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 safety monitoring and temperature regulation, for process heaters - Thyristor control panel - Interface to PLC - SIL calculation - Ex control panels for installation in hazardous areas

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.

Heating bands are the ideal solution for the heating of tubes an cylinders. Mica band heaters, frequently used as nozzle heaters, are made with a plastic-tight stainless steel casing. Such mica heating bands are in many dimension available from stock. The Ceramic heating band type is suitable specially for applications with high watt density and therefore for higher temperatures. Ceramic band heaters, also known as ceramic ring heaters or cylindrical ceramic sectional heaters, are attached to the contact surface by means of a clamping mechanism. A preferred field of use for ceramic band heaters is the heating of plasticising cylinders, bushings and nozzles of injection moulding machines and screw barrels of extrusion machines. For thermal optimization and process control ceramic band heaters can also be offered with insulation jackets or air cooling.

High temperature heater for pest control and drying processes Our high temperature electric heater model KILL MANN is an equipment designed and manufactured for pest control and drying processes where hot air at high temperature is required. The electric heater can be placed inside or outside the space that we want to disinsect or dry. The hot air will be directed towards the room repairing the heat evenly in all the corners where the insects can be found. Heat sensitive material should be removed from the room as the temperatures reached can damage them. The insects will die at a temperature of 48 °C for 150 minutes but if we increase the temperature to 55 °C for 60 minutes it will cause the elimination of the pest in all its stages (egg, larva, chrysalis, fully developed insect) by destroying the proteins from the body, a decisive factor in successfully eliminating the pest.
