Cryogenic tank is used to fold the compressor refrigeration technology, using the thermal equilibrium principle and circulating mixing mode, achieve the sample uniform cooling, constant temperature automatically, it can fully meet the national standard GB/T229-2007 "metal" charpy pendulum impact test method of the temperature control indicators.The compressor is imported from taikang of France, the equipment is easy to operate and high efficiency, it is the ideal sample cooling and thermal insulation equipment in the metal low temperature impact test.It can also be used for other low temperature detection and testing.
GB/ t229-2007 "metal charpy pendulum impact test method"
Cryogenic tank by the cascade refrigeration compression main body, control box, cooling tank, cooling medium circulation system, automatic alarm system and other parts, equipment after start-up, high temperature of the compressor start automatically (chronograph 8 minutes can't regulate), refrigeration system into the formal work.The refrigeration compressor continuously works, when approaching the setting temperature, the electric control system automatically adjusts the refrigerating quantity and heating, slows down the cooling rate to achieve the purpose of constant temperature.Stirring allows the cooling medium in the cooling tank to circulate continuously to achieve uniform temperature uniformity in the tank.
