Single-stage heated pressure regulator for gas analysis sytem | GENIE GHR

The GENIE GHR single-stage heated regulator prevents sample gas condensation during its expansion. 
 
This phenomenon is often caused by the Thomson-Joule effect, especially when the gas has a high pressure, a high dew point or evolves in a low temperature environment. 
 
To preserve the integrity of the sample throughout the process, the GHR incorporates a unique internal architecture with a long and spiral flow path. 
 
This design is combined with two strategically placed heat exchangers before and after relaxation. 
 
The first exchanger raises the temperature of the gas upstream of the pressure reduction, thus keeping the gas above its dew point.
 
The second exchanger reheats the sample after expansion, avoiding any condensation in the transfer line.
 
This double heating ensures the physical stability of the gas and limits the risks of condensate formation. 
 
The electric cartridge heater, combined with a proportional temperature controller with digital display, offers precise temperature control and integrated thermal protection.
 
The alternative, a self-limiting heating block, is a simple, reliable and compact solution. 
 
Compact, with a low internal volume, the GHR regulator offers fast response time and excellent dynamic behavior. 
 
However, this pressure regulator is not recommended for use with hydrogen, helium or neon.
