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.

Maximum measurement accuracy with simple operation Dräger tubes are calibrated short-time rapid measurement system, which determines quickly and inexpensively various gas concentration currently. With easy operation highest measurement accuracy for gases, vapours and aerosols is achieved. Individual- and simultaneous measurements are possible, either air or technical gases and in water or bottom sludge. During the shelf-life (normally 2 years) no calibration is necessary. Several measurements with only Dräger tube are particularly possible Generally one package contains 10 Dräger-tubes (PU), some articles contain fewer tubes, but then the deviating number is stated in brackets. Dräger tubes indicate standard measuring range; any possible deviation of measuring range can be read in instruction for use. With short time measurements, the indicated measuring time refers to stated number of strokes for each tube. If the measurement time is less than 1 minute, the time record is...
