Affinity FAA-050K Lytron Air Cooled Chiller

The Affinity FAA-050K is an air-cooled chiller engineered for precise thermal management in demanding industrial and laboratory environments. This unit delivers consistent cooling performance across laser cooling, semiconductor manufacturing, and other temperature-critical processes requiring stable thermal control. The air-cooled condenser design eliminates external water infrastructure while maintaining tight temperature regulation through digital control and hot gas bypass systems.

– Technical Specifications

– Compatibility & Integration

The FAA-050K accepts water, deionized water, oil, and Ethylene Glycol/Water mixtures—consult factory for PAO or non-standard fluid compatibility. Do not use automotive antifreeze or silicate-containing formulations, as these cause pump seal failure. RS-485 and RS-232 interfaces enable remote monitoring and control through WinChill software.
