Most factory A\/C evaporators from the 80s and 90s are now outdated in both design and materials.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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_6.jpg?v=1775143540\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_4.jpg?v=1775143541\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_5.jpg?v=1775143540\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe CSF engineers have once again applied modern design and manufacturing techniques to this classic Porsche evaporator.

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 in the last ~5 years due to environmental restrictions, so any new OE unit no longer comes coated from the factory.\u003c\/p\u003e\n\u003cp\u003eNo 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.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_OE-White-Flakes_1.jpg?v=1775143541\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_OE-White-Flakes_2.jpg?v=1775143541\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_OE-White-Flakes_3.jpg?v=1775143541\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch6\u003eCSF vs Griffiths Kuehl\u003c\/h6\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.facebook.com\/MotorsportInc\/\" target=\"_blank\"\u003eMotorsport Inc\u003c\/a\u003e was able to provide the CSF Engineering Team with a discontinued aftermarket evaporator from Griffiths. The Kuehl High Performance AC Evaporator was the go to replacement for 964 and 993 owners for many years. It offered improved A\/C Performance as well as an anti-corrosive coating so owners didn't have to deal with the dreaded snow flakes. However, these were discontinued over 5 years ago and there have been no alternatives since.\u003c\/p\u003e\n\u003cp\u003eThe Griffiths design was definitely better than the extremely dated mechanical design used in the OE unit. However, there was still plenty of room for improvement. The Kuehl Evaporator utilized a triple pass tube and fin design. While this was more efficient than the OE serpentine tube style, the triple pass design causes more back pressure than a single pass design like the CSF Evaporator uses. This back pressure raises the temperature of the refrigerant lowering the overall efficiency.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_comp_4.jpg?v=1775145207\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_comp_5.jpg?v=1775145207\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0677\/2893\/3037\/files\/8368_comp_6.jpg?v=1775145207\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eThere was also more space between each core than ideal, causing additional airflow restrictions. This empty space also reduces the overall refrigerant capacity. The CSF Engineers designed the dual cores to sit as close to each other as possible offering the best possible airflow and maximizing refrigerant capacity. CSF's Super-High Pressure Multi-Channel Microtubes also offer increased performance over the basic tube design of the Kuehl Evaporator.\u003c\/p\u003e\n\u003ch6\u003eWhy Upgrade?\u003c\/h6\u003e\n\u003cp\u003eWhether you are restoring a 964 or 993 to show-car condition or upgrading your weekend toy for modern comfort, CSF's OEM+\/Performance A\/C Evaporator is a no-brainer. No more white flakes\/dust blowing out of your vents and no chance of it happening in the future. This is the best and current only solution to a proper functioning A\/C system for the 964 and 993.
