The “STR type electrical process flow heater comprise a large range for industrial application custom built to meet client specification. These heaters are supplied CE marked in acc. the latest CENELEC requirements or manufactured to the latest IEC standards.

Typical electric process heaters applications include heating of liquids i.e. heat transfer oil or fuel oil, glycol reboilers and water heaters and heating of pressurized gases i.e. pressurized air, superheated water steam, nitrogen or other compositions of gases.

The “STR-TWIN type electrical heater comprise a large range of process flow heaters for industrial application custom built to meet client specification. Due to the small diameter construction of the vessel it is perfectly suitable for low volume or mass flow. These heaters are supplied CE marked in acc. the latest CENELEC requirements or manufactured to the latest IEC standards.

Typical electric process heaters applications include heating of liquids i.e. heat transfer oil or fuel oil, glycol reboilers and water heaters and heating of pressurized gases i.e. pressurized air, superheated water steam, nitrogen or other compositions of gases.

Thyristor control systems are also designed and supplied by OhmEx to control the range of electric process heaters. We are pleased to advice on the most suitable control system for your heating application.

The “STR-Exe” type electric process flow heaters are EEx e certified. These heaters are custom built to meet client specifications and suitable for use in zone 1 & 2 hazardous areas.

In general a cooling down takes place at expansion of gases whilst a heating takes place at compression. Typical gases are carbon monoxide, natural gas and air. The temperature change, which occurs at expansion of gas or gas mixture from a high to low pressure i.e. after a gas pressure control is called Joule-Thomson effect.
In order to prevent the effects of Joule-Thomson as icing or condensate separation, the gas will be heated up before expansion. The gas pre heaters are suitable for all kind of gaseous media (i.e. air, natural gas, technical gases, fuel gas) and low flow process applications, suitable for pressures up to 300 bar.

The “Cast electric heaters” type flameproof electrical gas pre heaters are certified for use in zone 1 or 2 hazardous area, custom built to meet client specification. The gas pre heater consists of a process tube coil and an electrical heating bundle, casted in aluminium. The process gas flows through the tube coil and is heated by the aluminium block that provides the heat transfer. This indirect electric heating gives an accurate control of the process and eliminates pressure vessel design and associated costs.
