Electrical gas preheaters


Electrical gas preheaters

Heat – for all gases up to 650°C
And safety– for operation in EX hazardous areas and for high pressure up to 500 bar.
Our solution – tailored exactly to your needs

Typical appilcations:

  • Gas pressure reduction stations
  • Seal gas and fuel gas heaters

Advantages of ELMESS gas preheaters:

  • designed according to customers’s individual requirements
  • safe and reliable operation
  • simple installation
  • low service requirement
  • long lifetime

Special design with inline process connections:
Due to a special, double-walled design, the heat loss is reduced. Inlet and outlet nozzles are one the same level.

Block type gas preheaters

The medium is heated up indirectly inside a tube coil. The tube coil and the electrical heating inset are cast in an aluminium block which serves as heat transfer medium.
