CSF Cooling - Racing & High Performance Division Porsche 964 / 993 OEM+ Performance A/C Evaporator 8368

Description:

CSF has decades of experience designing and manufacturing A/C Condensers and has leveraged that knowledge to design its first high performance Evaporator. Most factory A/C evaporators from the 80s and 90s are now outdated in both design and materials. They were originally designed for R12 refrigerant, which offered far superior performance compared to today's more environmentally friendly R134a. Even brand-new OEM evaporators are not efficient enough to provide a proper temperature differential with R134a. That's where CSF steps in.The CSF engineers have once again applied modern design and manufacturing techniques to this classic Porsche evaporator. Working closely with Motorsport Inc as a development partner, CSF was able to test, measure, and develop the new evaporator with both old and new OE units as well as a now discontinued Griffiths evaporator for reference. Test fitting was done in the full HVAC Suitcase courtesy of the team at Motorsport Inc.The result is an evaporator that fits perfectly, outperforms the factory system by a significant margin, and costs less than a new OEM unit. Based on testing, the CSF Evaportator fits and seals 2 times better than the factory or discontinued Griffiths units. A better seal means more airflow over the evaporator and in turn, better AC performance.The new 964/993 Evaporator utilizes a modern parallel-flow dual core design. Parallel-flow evaporators are far more efficient than old serpentine style designs like the OEM unit for the 964 and 993. These new cores feature CSF's Super-High Pressure Multi-Channel Microtube for Optimal Flow and Maximum Surface Area Contact.The CSF evaporator also features an anti-corrosive powder coat finish so there is no chance of oxidation or corrosion in the future. Corrosion and oxidation are what leads to the common white flakes/dust particles that blow from the vents of the 964 and 933.For the first 25 years, since the introduction of the 964, the original Behr/Mahle evaporators came with an anti-corrosion coating from the factory. Over time that coating has worn down and caused evaporators to corrode and oxidize. Normally a factory replacement will buy you plenty more years of good service. However, factory clear anti-corrosive coating for the evaporators was banned after 2020 due to environmental restrictions, so any new OE unit no longer comes coated from the factory.No coating means a new OE evaporator will begin oxidizing and corroding immediately. Many owners and builders have had their A/C systems turn into snow blowers within just a few months of installing brand new OE units. This issue plagues everyone from DIY inclined owners to the most prestigious and notable Porsche restoration companies.The CSF Evaporator was designed to solve this issue for good. The anti-corrosive powder coat finish offers the ultimate form of protection from oxidation and corrosion. Installing the CSF unit will give you the peace of mind that you won't ever have to worry about your evaporator again. If you've ever had to replace one of these, you know the value of never having to do it again. The HVAC Suitcase, which houses the evaporator, sits behind the dash and requires a significant amount of labor to remove and reinstall.
