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.

It is manufactured from DuPont Nomex coated with an aggressive solvent resistant acrylic pressure sensitive adhesive. Designed for high temperature electrical applications where a thin, strong and puncture resistant backing is required. Thin, strong and puncture resistant backing Chemical resistance Nomex high temperature film Phase insulation of electrical motors, generators, etc. Outer wrapping, tabbing and anchoring leads of electrical transformers, coils, etc.

It provides excellent bulk and stiffness in an easy to tear product. Polyester Non-Woven laminates are puncture resistant and highly conformable making these tapes ideal for wrapping around sharp corners and edges. Applications • Ground and barrier insulation for electrical motors, generators, etc. • Outer wrapping, tabbing, harnessing and anchoring leads for electrical transformers, coils, etc
