Low-temperature cooling system for cooling applications down to -180°C This KALTGAS system is designed for a temperature range down to -180°C, in which the temperature control system is only designed to generate a cold gas flow. The low temperatures are achieved by using cold nitrogen gas. The liquid nitrogen is vaporized in the LN2 storage tank and is thus available as a cold gas for temperature control. This constant, cold gas flow can be used, for example, to blow on the object to be cooled or to direct the gas flow into a test chamber for cooling. • Thermal testing of plastics, metals, composite materials, etc. • Cooling of electronic components • Deep freezing of sample chambers • Shock freezing of biological samples, foodstuffs, other materials • Tempering of test samples: -Tensile or torsion test -Notched bar impact test -Chemical or physical experiments -Process engineering processes KALTGAS is a temperature control system based on the low temperature of liquid nitrogen as a refrigerant. The liquid nitrogen is vaporized in a cryogenic tank by means of a heater (jet). This generates a constant, cryogenic gas flow. By varying the heater (jet) on the safety power controller (SL1), both the cooling capacity and the gas flow volume can be changed, and the LN2 consumption can be reduced to the necessary minimum by varying the jet power. The cryogenic gas flow is then fed through a vacuum-insulated, flexible metal pipe to the object to be cooled. A KALTGAS system can generate a cold gas flow of up to -180°C within a few minutes.
