Open type heat pumps for industrial heat recovery
Optimize your ammonia refrigeration system efficiency by recovering and utilizing excess heat, transforming it into a valuable energy source for diverse industrial heating processes.

The GEA Open Type Heat Pump is engineered by GEA for industrial heating and ammonia refrigeration applications. This pump excels in recovering heat from ammonia refrigeration plants, using reciprocating compressors designed to handle significant temperature lifts efficiently. It’s particularly beneficial in food, beverage, and pharmaceutical sectors, where maintaining specific temperature thresholds is crucial. With heating capacities ranging from 300 kW to 3,500 kW, this system efficiently manages energy consumption through options like desuperheaters and subcoolers, tailored based on the heat carrier circuit’s requirements. Constructed with materials like AISI 316L and SMO 254, it ensures durability even in corrosive environments. The fully welded plate and shell condenser supports robust integration into existing production lines, with a design pressure up to 50 bar, utilizing natural refrigerant ammonia (R717). The equipment’s high efficiency is maintained even at partial loads, empowered by variable speed drives. This heat pump is a valuable asset for enhancing operational efficiencies in continuous, high-speed, and automated processes.
