Process heater - Import export

EEx’e’ certified electrical process flow heaters EEx e T1 – T6 ATEX 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. The “STR-Exe type electrical process flow heater comprise a large range for industrial application. 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.

Electrical process flow heaters 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.

Flameproof mini line heaters ATEX Ex II 2 G Ex’d’ IIC T4-T6 nach EN60079-0 und EN60079-1 The Exheat range of flameproof mini line heaters consist of a screw plug or flanged type immersion heater mounted in a thermally insulated heating vessel. They are designed to efficiently transfer heat to a flowing medium (liquid, air or gas). All flameproof heaters are fully ATEX certified and designed for use in zone 1 & 2 hazardous areas, gas group IIC.

Explosionproof/flameproof gas preheater EEx d -ATEX und IECEx zertifiziert 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.

Control Panels for electrical process heaters OhmEx has extensive experience in the design of heater control systems and requirements for ‘load splitting’. Loads can also be divided into stages to give thyristor control and in addition combinations of thyristor and contactor control can be supplied to provide a fully synchronised system and limit impact on the power generating system. We can recommend cost-effective solutions to clients, outline requirements, or work to detailed specifications. In-house design facilities are supported by experienced engineers, backed-up by modern CAD facilities. OhmEx adopts an integrated project management approach to each contract, which provides effective co-ordination of design, procurement, manufacture, test and, where required, commissioning. Attention is paid to ensuring that each system is built to the demanding standards of our client, the environment and current legislation. Each control system is fully function-tested for correct operation, as a standard. Each test is simulated using the correct type of input signals to avoid start up and commissioning problems. A range of temperature control systems suitable for anything from small space heating systems to large process heating systems, including full PID control can be offered.
