Advantages and differences between sealed and non-sealed recirculating chiller

May. 13. 2022

The sealed circulation chiller is a kind of mechanical equipment using air-cooled fully closed compressor refrigeration and microcomputer intelligent control system. Its main function is to quickly cool the liquid during the test process. Different from the ordinary circulation chiller, it can not conduct low-temperature test directly in the tank, but must be used with other equipment or instruments.

Advantages and differences between sealed and non-sealed recirculating chiller

The ordinary cooling circulator is a low-temperature liquid circulating equipment cooled by non-sealed mechanical form. Compared with the sealed type, its cooling mode is that there is an open cooling tank on the upper part of the body, which can be used directly with the rotary evaporator. During the test, the speed and displacement can be adjusted at any time to facilitate the observation of the reaction process.


The sealed recirculating chiller adopts the fully sealed design. It has a faster cooling speed than the ordinary recirculating chiller and can reach the temperature required by itself in a short time. If it is accidentally shut down halfway, its heating speed will also be very slow, which is convenient to continue cooling.


Compared with ordinary equipment, the sealed recirculating chiller also has lower energy consumption, less medium loss, lower sound, less dirt and dust. At the same time, it also reduces the failure probability of the equipment, improves the safety of the equipment, and prolongs the service life and cost of the equipment.


These are the advantages and differences between the sealed recirculating chiller and the ordinary one. Dear friends, which one would you choose during the test?
