Four Seasons' line of remanufactured compressors now contains ICE 32, a refrigerant additive which the company claims extends compressor life and improves the overall performance of automotive air conditioning systems. ICE 32 works year-round to extend compressor life by reducing friction and protecting metal surfaces. It provides cooler air due to increased heat transfer, allowing the vehicle interior to cool faster while reducing interior humidity. ICE 32 is environmentally safe and does not contain chlorinated compounds.
