Non-standard Customization Air Cooled Screw Type Chiller
Features:
High/Low pressure protection for the compressor and overheating
protection inside the machine. Low water level alarm and low
temperature alarm. Imported compressor from Europe,US and Japan.
Refrigerating system welded with oxygen free method, to reduce
oxides and ensure the smooth surface. Throttle components from
Danfosss(Denmark) and Alco(US). SUS304 stainless steel water tank,
to avoid corrosion or water leak. Stainless plate, coil, shell, and
tube or fin type efficient heat exchanger. RS485 communication
function, to realize automatic management(optional). Electrical
devices supplied from OMRON, FUJI.TE,LG,MOELLER and SCHNEIDER.
Control mode:imported micro-computer or PLC(optional). Perfect
safety protection, failure display, and not requiring professional
personel for maintenance.Highly efficient evaporator and conderser,
to save over 30% energy. Temperature controlled 7-35°C:precision
controlled +_2°C.
