| 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. The LN2 vaporizer jet can be adjusted to minimize liquid
nitrogen consumption and to adjust both the cooling rate and the
gas flow.The cryogenic gas flow is then piped through a vacuum
insulated flexible metal line to the object to be cooled. |

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 or heat exchanger is installed. This module
can be connected directly to the line, or installed in a chamber
adjacent 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 defined temperature, is ready for use as a cooling agent.
With an optimized temperature controller 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.
Apart from the high cooling speed, another
advantage of KALTGAS systems is their modular design. By swapping
out individual modules such as the N2 gas line, the
LN2 vaporizer or the heater, it is possible to change
the cooling speed, LN2 consumption as well as the
application. The basic modules, including the LN2 container,
the vacuum pump and the safety control unit, remain unchanged. |
