pro cooler

I'm considering installing a "Pro-Cooler" to my ac system. Has anyone installed this device. I would like to hear from you. Is this more trouble than the cost of the unit? Does it do what the manufactorer claims it does?.

I thought the company that sells them went out of business.
From what I know its just a modified reciever/dryer and I dont see how it makes a difference enough to justify the cost,I have seen similar devices at Pep Boys you put on your a/c lines that sell for around 10.00 that make the same claims of removing moisture in the system and improving cooling
What makes the biggest improvement would be adding more condenser to remove heat .Performance Air in S Cal sells kits for mounting one under the body.

I have not taked to Pro cooler lately (about a year ago)so I don't know if they are still in the game. I think back then it was about $175.00 for the parts.
FWIW... A buddy of mine (Whom now instructs at a porsche mechanic training school in atlanta) has installed a few kits and they seem to have a more dramatic effect with cars that have the condenser mounted in the rear than cars that have them mounted under them it. (airflow)
He said they were a little better as both types sat in traffic but the "under car" did not seem that different once it was rolling.
The Rear type still seemed to improved when rolling.

hope it helps

I just bought a pro cooler yesterday for a customers care. It should bs installed in the next few weeks. He has a 1976 911S with only the rear condenser. I talked to Pro Cooler yesterday and the confirmed that cars with only the rear condenser will notice a big improvement over a car with both front and rear condensers. If you want more info at http://www.procooler.com

The current price is $300 + shipping - install time 2-3 hours (3X60= $180) + freon -
looks like about a $550 thrill. Has anyone actually tried one? I got a picture of it inatalled on a 911 from Pro Cooler (actually a blowup of the pic on their web site) looks like it wasn't engineered for a 911 - one of the hoses is awfully close to the tire.
Performance Aire sells a fan to go on the bottom of the small rear condensor in a turbo- wonder how much this helps and if 2 fans would work on a non-turbo? Also I have a turbo tail w/o a turbo has anyone tried a second condensor in the tail?

Just a note about pro cooler. Went to the web site listed to see what they had to offer and it seems to me that what they are selling can make a difference on your a/c load.

This is how it works. For argument sake, lets say the pressure (discharge)at your compressor at 98F (outside air temp) is at 235 psi with a refrigerant temperature of 138F. Lets also say that the refrigerant in the return line (suction) pressure from the evaporator back to the compressor is 45 psi with a temperature of 38F.

The pro air cooler is basically a heat exchanger. The refrigerant that is discharged from the compressor at 138F is run through the pro cooler. The refrigerant from the suction line at the evaporator at 38F also goes through the pro cooler. By doing this, heat transfer takes place and the discharge pressure/temperature from the compressor is lowered because the lower suction line temperature is used for the heat transfer.

This causes a lower pressure/temperature on the discharge side of the compressor after the pro cooler. The refrigerant pressure/temprature at the capillary tube is lower thereby incresing the refrigerant effect when it enters the evaporator. This effect causes the temperature on the evaporator to become lower causing a cooler enviornment. However, the capacity of the evaporator is not increased.

I hope this info helps in understanding how the pro cooler works.

This thread seems to have died. I tried to elicit a response from DMARV on 5/21 - no answer yet. Has anyone actually installed a Procooler and is it worth $500-600 ??? in terms of increased cooling?

Charlie '87 Carrera in Palm Springs (was
113 a few days ago !)

The new catalog from Tweeks arrived yesterday
they're now selling the procooler for $299.

Still waiting for a reply from DMARV on the results of his installation.

Has anyone actually used of of these devices?

Hi Charlie
Having lived in Palm Springs for 3 years can emphathise with your situation, I'll never forget the day i tried to ride my motorcycle in 129' heat, felt like I put my face in a 500' oven and I couldn't ride more tham 10mph

Anyway back to your situation I really don't see how this product can provide the claims made for $500.00 I suggest you call Performance Aire in LA, Cal they have a full catalogue of mods you can do to your 911 including a true rotary compressor (not the Sanden Type)

They also sell a condensor kit for the pan of the car along with a skid protector which is what will make the biggest difference in temp drops for the A/C they are also very knowlegeable and probably can give you a straight opinion on the pro cooler as if it worked as claimed they would sell it.

I'm suspicious of Pro Coolers' claims.

You can buy a new front condenser from Vertex for half the price of a Pro Cooler.

To me, that seems to make more sense.

Jack: Procooler replaces the receiver/dryer.
my '87 has a front condenser as do all 911's built since the early 80's)
