Cooling coil for direct expansion (DX)

HW-CW-DX

DX coils are an ideal cooling solution for VRV(F) units or third-party DX cooling systems, as they are filled with coolant which evaporates and thus allows the coil to function as a cooling coil. This process needs to occur in a cooling circuit driven by a cooling compressor.
