Kaltgas - Cryogenic cooling system for cooling applications to -180°C (-292°F) What is Kaltgas KALTGAS is a tempering system that utilizes the very low temperature of liquid nitrogen as a cooling agent. The Jet vaporizes the liquid nitrogen in a cryogenic container, producing a steady cryogenic gas flow. This LN2 vaporizer (Jet) can be adjusted to minimize liquid nitrogen consumption and to adjust both the cooling rate and the volume of the gas flow. The cryogenic gas flow is then piped through a vacuum insulated flexible metal line (N gas line) to the object you wish to cool. A KALTGAS system needs only a few minutes to produce a cold gas flow with a temperature as low as -180°C (-292°F). In most cases, this KALTGAS system is only used to produce a cold gas flow. The volume of the gas flow is adjusted with the safety control unit. Since the controlled system operates without a heat exchanger, it is not possible to maintain precise temperature stability. To achieve good temperature and control stability, a post-heating module (heat exchanger) must be installed. This module can be connected directly to the line, or installed in a chamber right next to the cold gas flow. The heat exchanger is designed to heat the cold gas flow to the desired temperature. The final product, a clearly quantified gas flow exiting the heat exchanger at a clearly defined temperature, is ready for use as a cooling agent. By embedding an optimized temperature controller inside of the safety control unit, a temperature stability of ±0.1°C can be achieved. With the standard safety control unit, a temperature stability of better than ±0.2°C can be achieved at a steady state.
