Filter and preheater in welded steel construction combined into one pressure device
For cleaning and preheating of gases in reducer stations upstream of gas pressure regulators
Suitable for natural gas, related combustible gases, hydrogen and non-aggressive gases
Pipe bundle tubes made of seamless carbon steel tubes
Benefits
Suitable for up to 30% H2 feed into the gas network
The compact design enables smaller station sizes when compared to typical standard devices
Stable fine cartridges guarantee high separation rates – the same as in the HPF cartridge filter
Customised design with free nozzle position, selectable gas rail axis, etc.
Lower differential pressure when compared to separately constructed filter and heat exchanger
Minimised effort for regular pressure device monitoring
Optional pre-pressure-resistant water chamber design – also with hot water SSV
Tube bundle complete or heat exchanger tubes only optionally available in stainless steel
Removable tube bundle for cost-effective maintenance and tests
Standard bundle sealing on the tube plate with O-ring, optionally available with flat seal
Special design also for hot water and gas temperatures of up to 120°C
Functional description
Cleaning of dry gases with solid particle impurities through the cartridge insert
Compensation for the Joule/Thompson effect by the heat exchanger – upstream of the gas pressure
regulator
Filter cartridge with galvanised outer and inner support cage, with impregnated, reinforced and folded cellulose, cartridge sealing reliably released by upper and lower perbunan ring
Cleaning solids: 99.6% > 2 µm 99.9% 3 µm
