Low Charge Refrigeration Ammonia Chillers Air to Water

We present our new modular Refrigeration Chillers with NH₃ refrigerant for medium and low temperatures (medium temperature powers from 110 200 kW to 2,2501500 kW). These are compact air-cooled chillers with microchannel condensers, oil-cooled air with stainless steel coils, three-stage oil separators, electronic expansion, and a semi-welded plate evaporator. These chillers are can be equipped with semi-hermetic or open screw compressors (depending on the application) and use natural refrigerant R717 as refrigerant (GWP = 0). The design allows a minimum refrigerant charge (up to 67 gr. per KW of refrigeration), a high COP, and very low energy consumption. This solution Our air-to-water Ammonia chillers represents the best solution in terms of environmental sustainability, energy efficiency, reliability, and innovation.
