View detailsIntroduction to Low Temp Chillers
Low temp chiller is a kind of refrigeration equipment which can provide cold source below 0℃. It generally refers to the use temperature from 5 to 35℃. The refrigerant can be carried by ethylene glycol or calcium chloride aqueous solution, and the evaporator with higher concentration needs anticorrosive treatment. The compression ratio of low temp chiller to the compressor is higher, so most cryogenic fields adopt a more complex system than a single compressor. Cascade compression or two-stag...
