Hi Tech Equipments offers Reciprocating Chiller A reciprocating chiller is a type of refrigeration system that uses a reciprocating (piston) compressor to remove heat from water or a coolant. The compressor works much like an automobile engine, using pistons moving back and forth to compress refrigerant. These chillers are typically used in small to medium-capacity cooling applications such as commercial buildings, industrial processes, and HVAC systems. They are known for their high efficiency at part loads, reliable performance, and relatively simple maintenance compared to some other chiller types. India, Bangladesh, Sri Lanka, Nepal
