The thermal heat pump features a low refrigerant charge and uses R404A and ethylene glycol. It is available in 21-ton and 42-ton units and is designed to efficiently reclaim up to 100% of heat through condensing. The unit contains a compact screw compressor, brazed plate heat exchangers for chilling and condensing, and can maintain all refrigerant inside. It has a touchscreen controller and can be pre-manufactured and shipped with pumps to easily pipe cold and warm glycol loops on site.
