Below is a list of Absorption Chiller manufacturers from Fullerton, California. Absorption chillers are an alternative to standard, electric chillers and work similarly to air conditioning systems. Instead of using electricity as power, these chiller systems run off heat. They are used when electric power conditions are poor, and they significantly reduce electricity costs associated with cooling, since they do not use a gas compressor. However, absorption chillers do require greater pump energy than electric chillers.
