Product Details

Functional Features/ product function

Corrosion resistant water-cooled chiller

basic function

•Adopting imported compressor heads from Europe, America, and Japan
•Inner copper tube adopts oxygen free welding method
•Adopting SUS304 stainless steel PP plastic water tank
•Computer PC board self optimizing microprocessor or touch screen PLC
•Efficient condenser and evaporator can save more than 30% of the source
