Whether High Low Temperature Test Chamber Can Do + 180 C Test or Above

At present, The high low temperature test chamber in domestic market generally do highest temperature test till + 150 C, only some companies with good technical ability can achieve + 180 C.

The main reason is that the compressor's refrigerated oil is easy to carbonize at high temperature and cause pipeline blockage, so it is not recommended to run at a higher temperature than + 180 C.

If the operating temperature above + 180 C,should be use the liquid nitrogen refrigeration, because there is no problem of refrigerating oil in liquid nitrogen refrigeration, high temperature can be done higher, low temperature can also be done lower
