The electrical heaters EHA are high pressure heaters designed for evaporation and/or superheating of carbon dioxide, nitrogen, oxygen, argon, and their mixtures.

The EHA heaters are primarily intended as trim heaters of high pressure gas, but can be used also as pressure build-up vaporizers, or product vaporizers in technical gases applications.
The heat exchanger bundle of spirally wound stainless steel tubes is together with electrical heating rods cast into aluminium block that provide for superior heat transfer properties.

There are no valves on the heater. Isolation and relief valves shall be a part of the system the heater is incorporated in.
