The whole liquid circulation of the high and low temperature heating and refrigeration system circulation device is sealed, with an expansion vessel, the expansion vessel and the liquid circulation are insulated, and do not participate in the liquid cycle, but are only mechanically connected, regardless of whether the temperature of the liquid circulation is high temperature or low temperature The medium in the expansion container is lower than 60 degrees
.
The whole liquid circulation is a closed system, there is no absorption of water vapor at low temperature, no oil mist is generated at high temperature, and heat conduction oil can be a wide working temperature; There are no mechanical and electronic valves
used throughout the circulation system.
Features of high and low temperature heating and refrigeration system circulation device: 1, wide working temperature range, with heating and refrigeration function, large temperature range: -25 °C ~ 200 °C, HRV series is -25 °C ~ 200 °C
.
2.
Controller with 2 LED displays, can display temperature set value and actual value, as well as overtemperature alarm value
at the same time.
3.
Efficient and fast, simple
to fill liquid.
4.
Ensure rapid cooling under high temperature; It can achieve continuous temperature
control from 200 degrees to -25.
5.
The circulation management is fully closed treatment, without oil mist and water absorption, which ensures the safety of the experiment and the life
of the heat transfer fluid.
, 6, refrigeration unit American Copeland compressor, circulating pump, stable performance, reliable quality 7, with self-diagnosis function; freezer overload protection; High-pressure pressure switch, overload relay, thermal protection device and other safety functions
.
8.
Control the temperature of the heat conduction medium, and use the same heat conduction medium
for the entire heating and cooling process.
9.
High head design to meet the long-distance transportation of heat conductive medium
.
