Introduce of the heating and cooling circulator
The high- and low-temperature circulation device is also known as the ‘heating and cooling circulator,’ ‘cold-and-hot integrated unit,’ or ‘heating and cooling circulator.’When the temperature of glass reactors, reactors, rotary evaporators, extraction equipment, and other devices paired with the high- and low-temperature integrated unit needs to be rapidly increased or decreased, this equipment can quickly bring them to the set temperature. The equipment can switch between heating and cooling modes swiftly, and it uses the same medium—thermal oil—thus completely overcoming the previous drawback of requiring two separate instruments for heating and cooling. The entire liquid circulation system of the high- and low-temperature circulating unit is sealed and equipped with an expansion tank. The expansion tank and the liquid circulation system are thermally isolated and do not participate in the liquid circulation; they are merely mechanically connected. Regardless of whether the liquid circulation operates at high or low temperatures, the medium in the expansion tank remains below 60 degrees.

Safety Protection
Features self-diagnosis capability; compressor overload protection; high-pressure switch, overload relay, thermal protection device, and other multiple safety features.
Sealed Circulation
The entire system is fully sealed. At high temperatures, there will be no oil mist; at low temperatures, it won't absorb moisture from the air. During operation, the system won't experience pressure increases due to high temperatures, and at low temperatures, the heat transfer medium will automatically be replenished.
