Screw Industry Cold Water Aircrew

1. the machine adopts international advanced semi-hermetic screw compressors, motors, compressors, integration, taking into account without shaft seal leakage; 2. double compressor or compressor start, down-cycle control, balanced load the parts life extension; 3. efficient and reliable flooded evaporators, and energy-saving electronic expansion valve orifice adjust refrigerant flow and evaporator liquid level changes; 4. mechanical and adsorption separation of primary and secondary oil to ensure oil return more reliable; 5. compressor unloading relief starts to avoid impact on the power grid; 6. dual-compressor units or above using multiple refrigeration circuits, when one of the loops to maintenance, the other loop is still running, with stand-by function; 7. small vibration, low noise, and adoption of R134a refrigerant and reduce environmental pollution.
