the entire liquid circulation is a closed system. There is no absorption of water vapor at low temperatures. There is no oil mist at high temperatures. The heat transfer oil can have a wide operating temperature; mechanical and electronic valves are not used in the entire circulation system.

Features:
Wide operating temperature range, with heating and cooling function, the maximum temperature range: -25 C ~ 200 C.
A controller with 2 LED displays that simultaneously displays temperature setpoints and actual values, as well as overtemperature alarm values.
Efficient and fast, easy to fill.
It can ensure rapid cooling under high temperature conditions; it can realize continuous temperature control from 200 degrees to -20 degrees.
the cycle management is fully enclosed, without oil mist and water absorption, ensuring the safety of the experiment and the life of the thermal fluid.
Refrigeration unit US Gulun compressor, circulating pump, stable performance and reliable quality.
with self-diagnosis function; freezer overload protection; high pressure pressure switch, overload relay, thermal protection device and other security functions.
the temperature of the heat transfer medium is controlled, and the same heat transfer medium is used for the whole process of cooling.
High lift design for long-distance transport of heat transfer media.
