Kuehl Variable Speed Evaporator Fan Control
Speed Controller Board

The Kuehl Fan Speed Controller upgrade gives you complete control of your Porsche 911 or 930 evaporator fan motor, and much more. The stock Porsche fan speed switch limited fan speeds: "1" you could not feel, "2" was no better than 1, and "3" was full blast. Now you can have a gentle breeze or all the way to full factory full blast; infinite and fully variable fan speeds! The Kuehl Fan Speed Controller switch replaces your stock Porsche 911 or 930 switch on the right side of the ac console. The controller board is simply mounted in the passenger side air inlet. In addition to having a state of the art control, seldom found even in modern cars today, you now have a unique indicator light to tell you (a) when your a/c system is on, a "green" light and (b) when the compressor is running, a "yellow/orange" light ! We made the installation and wiring simple (no soldering, just plug and go, and of course our instructions make it easy for anyone to do). The Kuehl Fan Speed Controller system includes a new control knob for the right side fan speed, new fan speed switch, wiring harness, fan speed controller board, system indicator LED, all necessary terminal connectors and detailed instructions.

Compressors OEM - York Compressors
late 1960s through 1983

The Porsche 911 used various a/c systems in the early years, some made by Delanair (later became part of VPC or Volkswagen Products Corp), another firm called Coolaire and Behr. Earliest systems used a Tecumseh 5cu.in. and York 6cu.in. Around 1971 the York 10cu.in. (size shown in the right side picture) became common in the Porsche 911 and 930 up through 1983 (in 1983 the euro 930 starting using the Nippondenso). The York design is uses a crankshaft type piston mechanism. Griffiths stocks brand "new" York 10cu.in. compressors, available without clutch.

York Manifold Fittings

For your Porsche 911 and Porsche 930 we also stock the York compressor manifold valve fittings with base seal that your hose lines connect to (manifolds fail with time and corrosion). If you want to improve your systems performance: cut down on weight, vibration and engine loads, consider upgrading to our Kuehl-507 compressor kits shown below.

Kuehl-507 Rotary Piston Compressor - Update Kits
replaces the York
Kuehl Compressor

Our Kuehl-507 (pronounced as "cool") Porsche 911 and Porsche 930 upgrade kits (for 911's prior to 1984 and turbo's prior to 1983) offer many benefits over the original York compressor found on the early Porsche 911 and Porsche 930 up through 1983. The Kuehl 507 compressor uses a "wobble-plate" update design and is built alike a Sanden compressor. The wobble plate moves five smaller pistons as compared to the York that uses a crankshaft to move two large pistons. The Kuehl 507 compressor wobble-plate update design requires less horse power to turn and is a better match for the condenser area. Our Kuehl 507 upgrade kit uses less engine compartment space & less horse power to turn. You will notice it runs smoother & quieter and improves system efficiency. The Kuehl 507 compressor upgrade and its Kuehl Kwick mounting bracket bolt directly to the original York sub or base plate, which saves you lots of time and knuckle scraping during installation.

For your Porsche 911 and Porsche 930 you can purchase our Kuehl-507 Kits in three configurations to match your objectives & budget: from bare bones compressor with essential replacements to complete system overhaul, such as brand new hose lines made of barrier hose with bead lock crimped fittings. Our new barrier hose lines reduce system refrigerant loss. All Kuehl-507 kits include our exclusive "high-low" pressure cut-out switch feature. The switch prevents the system from running when the high side pressure is either too low or too high. This special features helps to prevent compressor failure and is required by the EPA in certain State applications. We offer our Kuehl-507 Kits in either R12 or R134a in various configurations to meet your performance requirements. We also offer Kuehl-507 Kit's bundled with our Kuehl Condenser Systems packages for additional cost savings.

OEM - Nippondenso Compressors
1984-1989

In 1984 Porsche started utilizing the swash-plate multi-piston driven Nippondenso in the 911. This compressor design proved to be smoother, quieter and more efficient as compared to the York. The Nippon can also be found on imported 1983 930s. Griffiths stocks new Nippondenso compressors with and without clutch, in both R12 and R134a configurations. If you are considering purchasing our Nippondenso compressor inquire about our bundled discount package in our Kuehl Condenser Systems for a major improvement in cooling and cost savings.

Condensers

911 Porsche Rear Deck Lid Condenser
Non-Turbo Rear Condenser

All Porsche 911 typically have a "rear deck lid" condenser which is mounted on the underside of the engine lid. Air movement created by the engine cooling fan is drawn across the condenser. There were four variations of the rear deck lid condenser: on early Porsche 911 narrow bodies, depending upon whether the installation was "factory air" or after-market, had a simple but crude serpentine type design with flare fittings, then there was a single row tube and fin coil, next came a higher efficiency two row tube and fin design, and around 1984 the hose connection fittings changed to o-ring and the coils tubing was reduced in diameter in an attempt to provide more cooling surface (however it is not noticeable), and a similar design had a modification in the mounting for applications having a rear wiper. Griffiths stocks new high efficiency two row tube and fin designs for early flare fitting requirements, up through 1983, and o-ring fitting types for 1984 through 1989 applications with and without rear wipers.

Condensers should be gently cleaned annually. Use a soft bristle brush with very warm water and soap. Signs of oil with dirt accumulation can be a sure note of leakage. You can straighten bent cooling fins using a pair of tweezers and small flat blade screw driver (be very careful to avoid the tubing). Deck lid condensers get their air movement from the engine cooling fan; the higher the engine speed the more air movement across the deck lid condenser, so never operate your ac system with the deck lid up otherwise your system pressures will drastically rise.

930 Porsche Rear Deck Lid Condensers

Stock OEM	Kuehl High Performance


Tube and Fin	Serpentine

Above on the left side is stock 930 Porsche "tube and fin" two row construction deck lid condenser as found on 1978-1989 turbos. The condenser size is nearly half of the that of the 911Porsche deck condenser, so overall performance of the 930 is less in comparison to the 911. As air attempts to pass through a tube and fin type coil air masses converge and deflect air away from the tubing surface; note the large tear drop shaped "hot spots" (shown in red) on the trailing edge of the round tube cross section.

Above on the right side is the Kuehl 930 Serpentine high peformance deck lid condenser, which is a direct drop in, bolt on, replacement for stock factory condenser. This new condenser utilizes next generation "serpentine" tubing. The benefits of the Kuehl Serpentine lay in the unique serpentine tube design which is found in today's vehicles using R134a. Rather than using old fashion round tubing with many braze joints the Kuehl Serpentine has one continuous multi-channel extrusion to channel the flow of refrigerant. The fin spacing is also greater. This design offers three advantages over the old tube and fin design: (i) with the larger fin spacing a greater volume and velocity of air moves across the condenser coil. (ii) Serpentine (rectangular cross section tubing) develops small and fewer "hot spots" as opposed to tube and fin; serpentine coils are more efficient and offer better performance. (iii) The Kuehl unit has only two braze joints rather than dozens as found on tube and fin designs.

911 and 930 Porsche Front Condensers

Stock OEM	Kuehl High Performance


Tube and Fin	Serpentine

Above on the left side is stock 911 and 930 Porsche "tube and fin" two row construction front condenser. The front condenser was introduced in 1978 with all cars having factory air conditioning; years through 1983 have flare fittings, o-ring fittings were introduced in 1984 (the 1983 imported 930's have o-ring fittings). Front condensers are found on the underside of the car's belly pan just behind the front air dam per se. This unit runs in series with the rear deck lid condenser. The front condensers also have a blower fan, located in the front trunk, which runs when the ac system is on. Overall cooling performance was helped with the addition of the front condenser and blower.

Above on the right side is the Kuehl 911 Porsche Serpentine high peformance front condenser, which is a true direct drop in, bolt on, replacement for stock factory condenser. Alike the 930 deck lid serpentine, this new condenser utilizes next generation "serpentine" tubing. The benefits of the Kuehl Serpentine lay in the unique serpentine tube design which is found in today's vehicles using R134a. Rather than using old fashion round tubing with many braze joints the Kuehl Serpentine has one continuous multi-channel extrusion to channel the flow of refrigerant. The Kuehl Serpentine front condenser out peforms the old fashion OEM tube and fin condenser for various reasons. The Kuehl's design offers three advantages over the old tube and fin design: (i) A combination of more surface area with larger tube spacing gives you a greater volume and velocity of air moving across the condenser coil, as much as 40% more air!. (ii) There are fewer "hot spots" (shown in red) , sections of the tubing which do not receive sufficient air contact. Hot spots develop when round tubing profiles deflect air away from the tubing surface, such as when two air masses meet. (iii) The Kuehl unit has only two braze joints rather than dozens as found on tube and fin designs.

The competition literally crashed by trying to copy the genuine Kuehl concept:
1) The genuine Kuehl unit does not reduce the ground clearance in the 911 or 930 undercarriage. Some competitors, who try to work around Kuehl's unique fin design, think thicker is always better. A recent crash test proved them wrong: A unsupsecting 911 owner who purchased a competitor's "thicker is better" design nearly ripped the bottom off his 911's tub while driving over a railroad passing because the competitor's thicker is better philosophy design reduced the vehicle's ground clearance. So if you have a lowered suspension, or if you have ever worried about crossing railroad tracks, parking close to cement tire stops, or moving over a driveway transition, there is no need to worry with your genuine Kuehl front condenser
2) The Kuehl unit does not require special spacers.
3) The Kuehl unit fits under the existing stone guard.
4) The Kuehl hose connections fit the exisiting 911 and 930 hoses.

The "new" serpentine rearward mounted Kuehl Condenser

One of the keys to reducing your air conditioning vent air temperatures is to add a high efficiency condenser. Or simply put the more condenser the cooler you can be. Above are pictures of our new serpentine Kuehl (pronounced "cool") Condenser system with full time blower fan (This unit is mounted behind the LH rear tire) . A full time cooling fan offers greater benefits compared to static type condensers which require vehicle movement to keep air flowing across the condenser. Full time blower fans are needed when you are in slow traffic or sitting still. This is the smartest way to move the heat out of your refrigerant to the outside air, increase the BTU exchange. You'll bet lower vent temperatures and keep your system pressures at safe levels using R134a or R12 refrigerants.
The Kuehl Condenser mounts easily in the 911 driver's side rear fender, without any major modifications. This durable unit fits narrow, SC and turbo bodies. You do not have cut any body panels. Smartly designed too: supported on vibration mounts, attached with stainless steel brackets and we have made the hose routing a breeze. The unit is shipped pre-assembled with brackets and cooling fan attached.
Features include: durable condenser with cooling fan, stainless steel brackets, new barrier hose lines for hook-ups, vibration mounts, high/low system pressure cut-out switch, hose heat shield, fuse link, Bosch relay, stone guard kit, hose hangers, all necessary hardware & wiring, and detailed instructions with pictures for each step walking you through the installation along with recommend charging procedures.
When you order your Kuehl Condenser system you can smartly purchase other options at the same time to save on your investment: our new compressors kits, complete barrier hose sets, and the new Kuehl Evaporator. If you need customized configurations: you have added turbo flares or installed a different year engine, we can customize a package for you.
The Kuehl Condenser can be installed in most 911 bodies through 1989; narrow body, SC or turbo flares.
And, if you really want absolute cold air consider our new Duehl-Kuehl systems: two condensers with full time blower fans, one mounted in the front section and one in the rear section of the driver's side rear fender (see below). The new Duehl-Kuehl systems are especially great for turbo's with oversized intercoolers which may have required you to delete the stock turbo condenser in the rear deck lid. You can even go to extremes (as a few of our southern state customers have, running "four" condensers!)
The Kuehl Condenser systems offers a more reliable a/c system and opportunities to achieve vent temperatures in the low 30's F with R134a. To find out more about the Kuehl condenser we suggest reading:

The New Duehl-Kuehl Condenser

Above is our Duehl-Kuehl condenser, mounted in front of the LH side rear tire. For optimal cooling performance the Duehl unit is intended to be used in conjunction with (runs in series with): the rearward mounted Kuehl Condenser, the original deck lid condenser, and the front condenser (therefore having four condensers for a very chilly experience). Or for earlier cars, pre 1978 cars, which only have a deck lid condenser, you would run the Duehl Kuehl in series with your deck lid and the rearward mounted Kuehl unit (therefore having three condensers). Installation is very easy and no major modifications to the body (no hacking).

Driers

The receiver drier is critical component to your a/c system. The drier is as important as your oil filter is to your engine. It consists of a steel tank, a filter, desiccant bag (drying agent) and a side mounted site glass. Driers should be replaced whenever: (a) your system has lost its refrigerant and you are unsure of its age, (b) the system is suspect to excessive moisture, (c) you are changing over to an alternate refrigerant or incompatible refrigerant oils, or (d) your compressor seized or locked up. The drier can be found typically attached to the back side of the driver's side front wheel well. Griffiths stocks OEM style Kuehl brand driers with the correct desiccant for R134 and R12 refrigerants.

A word about: Subcoolers or Liquid-Suction Heat Exchangers.
Over the years we have received many inquires regarding "subcoolers". In simple terms, with respect to air conditioning, a subcooler attempts to use the residual cool refrigerant gas exiting the evaporator to further cool down the liquid refrigerant before it enters the expansion valve; a colder liquid refrigerant in many cases can yield colder vent temperatures. In theory this sounds great however in application subcoolers sometimes work and sometimes do not work, and here is why:
1) "For any fluid and system, a subcooler or liquid-line/suction-line heat exchanger (LLSL-HX) increases temperatures at the compressor inlet and outlet which is a shortcoming." (reference P.A. Domanski and D.A. Didion; J.P. Doyle, Evaluation of liquid line/suction line heat exchange in the refrigeration cycle, March 1994).
2) "Under closer evaluation, liquid-suction heat exchangers increase the temperature and reduce the pressure of the refrigerant entering the compressor causing a decrease in the refrigerant density and compressor volumetric efficiency". (reference - S. A. Klein, D. T. Reindl, and K. Brownell, Refrigeration System Performance using Liquid-Suction Heat Exchangers Published in the International Journal of Refrigeration, Vol. 23, Part 8, pp. 588-596 (2000).
3) In simple terms you could say the subcooler is (initially) stealing energy from one end of the system and trying to move it elsewhere; we kinda think of it as a cat chasing its tail. And, heat is a major killer of compressors, and increases in system pressures are what we are attempting to prevent.
4) One benefit of a subcooler is its ability to help reduce unwanted liquids from entering the compressor and causing potential damage. However, all Porsche's produced to date utilize an expansion valve type system and seldom if ever have issues with liquids entering the compressor, hence a useless application of the device.
5) You have to ask yourself, "If subcoolers are such a great idea (if they did work in automotive applications) why doesn't every BMW, Chrysler, Chevy, Ford, GM, or Mercedes have one! They are not expensive to make, you can put one together for under $100.00.

The Kuehl Evaporators for Porsche 911 & Porsche 930

Kuehl 911/930 Evaporator with Expansion Valve

Above is our newest high performance serpentine Kuehl Evaporator for the Porsche 911 and Porsche 930. This unit has more surface area than the OEM and is lighter too. In a recent head to head controlled test, the original Kuehl out performed the OEM evaporator as well as an inexpensive copy. The Kuehl unit simply has greater surface area yielding more btu's per square inch than any other; click on the Test Data box below for details. If you own a Porsche 911 or Porsche 930 and drive it then why settle for second best, ask for the original Kuehl Serpentine 911 930 Evaporator.

(click the box to read the test report)

The Porsche 911 930 evaporator is located in the "old gas heater" box under the front hood (on RH drive Porsche 911 or 930's the evaporator is located inside ahead of the center console). Evaporators typically get clogged with dirt and dust which prevents proper heat transfer. It's a good idea to check the condition of the evaporator every other year. Leakage will be noted by signs of oil film. Carefully clean out any accumulated dirt & dust from its inlet side. The expansion valve's capillary tube pigtail should be attached to the top of the evaporator outlet pipe and secured with a clip and insulated with ac tar tape. Your thermostat switch (on your ac console) has an aluminum sensor tube (filled with a gas) which is inserted in the evaporator. The sensor shuts off the compressor to prevent the evaporator from icing up which reduces system efficiency (do not bend the tube, if it breaks the system will not function). Bent fins can be straightened with tweezers and a small flat blade screw driver. Griffiths stocks evaporators for most models.

Expansion Valves

The Porsche 911 and 930, through 1989, used an externally equalized expansion valve. Expansion valves should be replaced when either, (i) diagnostics have confirmed valve failure or leakage, or (ii) your compressor seized or locked up.

Hose Line Assemblies

The average Porsche 911 typically has 5 hose line assemblies which account for 40 feet of rubber a/c hose line; the 930 has a greater overall hose length. This original type of hose was designed during the time period when R12 refrigerant was inexpensive and it's affect on the ozone level was not known. This old fashion hose line slowly leaks (permeates) refrigerant through it's skin overtime; this is not a design flaw nor was the design intended to do so, it was simply the way things were.
It was common to "top off" or recharge the system on a yearly basis. Today, with the high cost of R12 it's not wise to have leaks of any kind. With the introduction of R134a refrigerant the a/c industry determined that the original type hose leaked R134a at a greater rate than R12. To solve the problem a new type of hose was designed that has inner liner which reduces rate of permeation (leakage) of refrigerants through the hose wall. It's called "barrier" hose. You should inspect your hose lines on a yearly basis, looking for cracks, signs of oil or dirt accumulation on the hose or near the hose fittings. You may notice small pin size holes that are evenly spaced in a line running the length of your hoses. These are "pressure relief" holes which are installed by most hose manufacturers. The small holes allow pressure to escape in the event that the primary inner wall of the hose should fail under extreme pressure. The designers contemplated that it would be better to avoid a sudden eruption in the outer wall that could harm the vehicle or a technician working on the car. Under normal peak operating pressures refrigerant does NOT leak through these holes.
The rear deck lid hose receives a lot of bending, and the hose running under the car (from the rear condenser to the front or to drier for models without a front condenser) tends to get crushed by lifts. Griffiths stocks brand new hose line assemblies made of barrier hose. If your 911 or 930 has non-factory hoses we can custom manufacture new barrier hose assemblies for you!
Many 911's do not have a hi-low pressure cut-out switch. The EPA dictates that if you are switching over to R134a then you should install a switch. Griffiths offers the switch feature now in it's special barrier hose assemblies. Our special switch automatically prevents your system from operating when pressures are either too low or too high, thereby (i) "saving" your compressor from potential damage, and (ii) complying with the EPA requirements. It's easy to install too.

3.6 adapter

10PA15C Compessor with new adapter plate and hoses

After you drop the later 3.6 engine in your older tub, simply remove the original compressor manifold plate and bolt down our new adapter. Attach our new barrier hose lines, which include either R12 or R134a charge ports, and your ready to chill. Our new 3.6 adapter plate kit includes: the adapter, a new manifold base seal, o-rings, factory crimped barrier hose assemblies (compressor to condenser, and compressor to evaporator).

R134a Conversion Kits

Griffiths offers Kuehl R134a conversion kits to help you make the move over from R12 to R134a refrigerant easy. Our kits include new : low side and high side R134a charge port adapters with their own valve core (our solid steel body with its own valve core is superior to inexpensive aluminun types), an 8 ounce can of polyoester ("Ester") oil, a R134a compliance sticker, HNBR (Hydrogenated Nitrile) R134a compatible o-rings and our basic "How to Convert Guidelines". We also offer kits with new Kuehl receiver driers, the smart way to go, which contain XH9 type desiccant designed for R134.
We have been using ester type refrigerant oil in our conversion kits for the past 10 years. Ester refrigerant oil was developed for use when retrofitting an automotive compressor from R-12 to R-134A; the ester oil mixes with left over mineral oil. Ester type oil offers excellent miscibility with HFC R134a refrigerants.
Note: Prior to installing the R134a conversion kit the ac system must be evacuated by a quailified ac technician to remove the refrigerant. After installing the R134a conversion kit the ac system should be inspected, evacuated, refilled and tested by a qualified ac technician as well. We do not include R134a refrigerant with our kits as we believe that "charging" of the system is best left to an experienced ac technician who has the right equipment. This is not to say that you could not handle the task yourself, however good equipment is expensive and gaining experience can at times be more expensive.

The Kuehl Vent

Now you can have an additional air conditioning vent within a fingers touch. Our new Kuehl Vents! These are fully adjustable vents designed by Griffiths exclusively for your 911. The Kuehl Vents come in two versions. The original single Kuehl vent (shown above) replaces the factory "bow tie" floor vent located on the lower bulkhead (fire wall) in front of your AC floor console. It fits model years 1978-1989. The Kuehl Vent redirects the colder air from the bulkhead "floor" vent directly to you (rather than on your feet). Bulkhead air temperatures can be 5 F degrees colder than the sun baked dash vent temps.
The single Kuehl Vent installs in just 15 minutes (it's pre-assembled for you). This is a non-invasive installation (meaning no cutting or drilling or gluing) using just two wrenches. Kuehl Vent does not interfere with the ashtray operation. And best of all the Kuehl Vent design is as close to OEM as you can get (probably better), and it belongs there. Get more colder air with the Kuehl Vent.

The Tri-Kuehl Vents
The Kuehl Vent

Our latest addition to the Kuehl Vent product line is our Tri-Kuehl Vents package. The Tri-Kuehl Vent system includes the original Kuehl Vent mounted above the ac console plus two more Kuehl Vents, one mounted on the drivers side and one of the passenger passenger side knee pad. The left and right side Kuehl vents are screwed to the underside of the knee pad, installation is about 1.5 hours. The new Tri-Kuehl Vent will blow you away. Order your Kuehl Vents TODAY.
