The pre-bent original copper pipe layout perfectly matches the piping arrangement of the 30GT unit, minimizing the need for on-site brazing during major overhauls.

The metal housing stepper motor can effectively resist the erosion of condensate water and refrigerant vapor within the air-cooled chiller cabinet.

Only the dedicated 30GT EXV driver output is supported; direct power supply will immediately burn out the internal stepper motor windings.

Compared to model 32GB401044, the water-cooled 30HXC unit has a larger flow rate; the mechanical stroke and drive logic are completely different, and cross-model interchange is prohibited.

Before commissioning, it is necessary to completely evacuate the vacuum and remove refrigerant contaminants. Particle contamination will damage the precision metering orifice.

Common fault modes: stepper motor out-of-step leading to overheating protection, system impurities blocking the orifice, open circuit fault of the motor, unstable evaporator pressure fluctuation.
