According to user requirements, can be customized special specifications of low temperature constant temperature water bath, constant temperature reaction bath, low temperature reactor, low temperature constant temperature tank and other equipment, according to the needs of the production of step temperature control, real-time communication with the upper computer, real-time record of low temperature tank products. Based on the principles of low temperature condensation, low temperature solidification and low temperature adsorption, GM refrigerator is used to develop and produce a helium liquefaction recovery system, which can recover, purify and reliquify helium and run fully automatic. The portable helium liquidizer is a structure in which the refrigerator sinks into the liquid helium dewar. At the same time, the helium compressor and the liquidizer are integrated on a skid mounted. The overall size of the system is small, and the system can be moved when the liquid helium is turned on.

Detailed introduction

Note: According to user requirements, we can customize special specifications of low temperature constant temperature water bath, constant temperature reaction bath, low temperature reactor, low temperature constant temperature tank and other equipment. We can produce the low temperature constant temperature tank products according to the needs of step program temperature control, real-time communication with the upper computer, real-time recording. Based on the principles of low temperature condensation, low temperature solidification and low temperature adsorption, GM refrigerator is used to develop and produce a helium liquefaction recovery system, which can recover, purify and reliquify helium and run fully automatic.

The portable helium liquidizer is a structure in which the refrigerator sinks into the liquid helium dewar, and the helium compressor and the liquidizer are integrated on a skid mounted. The overall size of the system is small, and the system can be moved when the liquid helium is turned on. When the liquid helium is transferred, the liquid helium is directly transferred from the liquid helium dewar to the equipment used by the user, eliminating the transfer process of intermediate dewar and avoiding the liquid helium loss in the transfer process.

System Features:

1. Full automatic control, one-button start-stop, visual operation interface;

2. Modular design, high integration, the system can be deeply customized for user needs;

3. Provide equipment, installation and debugging services
