EVAPORATOR COIL
At KRN Heat Exchanger & Refrigeration Ltd., we design and manufacture high-performance evaporator coils that ensure efficient heat absorption and reliable cooling. These coils are a key part of the refrigeration cycle—responsible for converting liquid refrigerant into vapor by absorbing heat from air or process fluids.
Our evaporator coils are built for energy efficiency, long service life, and consistent cooling performance across residential, commercial, and industrial applications.
