Typical applications of refrigeration heating temperature control system:

Dynamic constant temperature control of cold and heat sources of high-pressure reactor, dynamic constant temperature control of cold and heat sources of double-layer glass reactor, dynamic constant temperature control of cold and heat sources of double-layer reactor and constant temperature control of cold and heat sources of microchannel reactor; Small constant temperature control system, temperature control of steam saturation system, material low-temperature and high-temperature aging test, combined chemical cold and heat source constant temperature control, semiconductor equipment cooling and heating, vacuum chamber refrigeration and heating constant temperature control.

Structure and principle of Dynamic Temperature Control System:

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃[because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.
