BluQ is an ammonia chiller with a semi-hermetic compact screw compressor. The heart of the system is the GEA CompaX, an ammonia screw compressor with suction gas-cooled electric motor. Compared to an open solution, the risk of leakage is minimized by eliminating the mechanical seal, making operation with ammonia as a refrigerant more attractive, says the manufacturer. A 3-in-1 design combines the motor, compressor and oil separator in a compact and hermetically flanged unit. To minimize refrigerant charge, the evaporator and the liquid separator are housed in a single housing.
