Low Charge Ammonia Chillers Air to Water

We present our new modular Chillers with NH3 refrigerant for medium and low temperatures (medium temperature from 200 kW to 1500 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 can be equipped with semi-hermetic or open screw compressors (depending on the application) and use natural refrigerant R717 (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. Our air-to-water Ammonia chillers represents the best solution in terms of environmental sustainability, energy efficiency, reliability, and innovation.
