Cryogenic Chamber

Name: Cryogenic Chamber
Brand: Xi'an LIB Environmental Simulation Industry

LIB Cryogenic Chamber adopts mechanical refrigeration, and the low temperature can reach -120°C. This cryogenic test chamber achieves energy saving, When the temperature needs to be stabilized again, the advanced PID control can effectively control the output value of the constant phase and the recovery phase.

Model: CF-100, CF-225, CF-500, CF-800, CF-1000

Standard: ISO 14965, ISO 21011, ISO 21013-1, ISO 9328-4

Cryogenic Chamber Features and Benefits

1. Replacing the traditional way of cooling with liquid nitrogen, LIB cryogenic chamber achieves a low temperature condition of -120°C through mechanical refrigeration.

2. The cryogenics chamber refrigeration system is reliable and stable, which can realize the test in a stable cryogenic environment.

3. The standard cryogenic chamber has 2 sample holders, which can be adjusted and disassembled to test specimens of different sizes. The air circulation system of the test chamber provides good air circulation, achieving good temperature uniformity.

4. The cryogenic chamber applies programmable control, which can realize 120 programs for testing. The cryogenic chamber can be controlled remotely through mobile devices; it can also be connected to the unified control system of the laboratory to achieve unified control and operation.

Configuration of Cryogenic Chamber

①Workroom	Cryogenic chamber workroom is made of SUS304 which has good high and low temperature resistance.The standard cryogenic chamber is equipped with a double sample holder. Sealing strips and precise sealing structure design prevent cold air leakages.
②Air circulation system	Air circulation systems are equipped with high performance fans which encourage air circulation in the workroom. In the cryogenic test, temperature uniformity is a very important indicator, requiring ±2 ° C.
③Heating system	The use of nickel-chromium alloy heating wire, etc., can quickly generate heat, from the cryogenic state to a higher temperature when the heating system needs to play a role. The highest temperature can reach +150℃.
④Refrigeration system	A cascade mechanical refrigeration system is adopted.It is mainly composed of a compressor, a condenser, a throttling device (capillary) and an evaporator to form a refrigeration cycle to control the low temperature to -120°C.
⑤Control system	The heating system and cooling system is controlled by PID algorithm. The control system also has various safety protection functions, such as over temperature protection, compressor overload protection, etc.
