Working principle:

 

This product is mechanically cooled by a totally enclosed compressor. The inner wall of the cooling tank has cooling copper coils. The refrigerant (Freon) continuously circulates through the coil on the inner wall of the water tank to cool the refrigerant in the tank. And then the refrigerant is conveyed to interlayer of the supporting equipment or the condensation coil through built-in circulation pump and external circulation pipeline. This method can cool the material in the reactor indirestly, and  also  cool & liquefie the steam in contact with condensation tube.

Generally speaking, this product can connect with the interlayer of a double-layer glass reactor, rotary evaporator, and condensation coil of the reactor for usage. It is also feasible to directly  put objects or containers which need to be cooled into the bath for cooling or reaction.

The outlet pipe of this product is connected to the lower inlet pipe of the kettle or condenser. The circulating liquid comes out from the upper circulation port and returns to the inlet of this product through the pipe, forming a complete circulation.
