Below is a list of Process Chillers manufacturers from Morgan Hill, California. Process chillers are a type of industrial cooling system that is used when HVAC water chillers do not provide enough cooling power. They use refrigerants like ammonia and halocarbons to cool facilities, machinery and products during and after industrial processes that generate large amounts of heat. They provide very effective cooling, and may be compact and portable or centralized chiller systems that are installed indoors or outside.
