The range of "Cast electric heater" explosion-proof gas preheaters are certified for use in Zone 1 or 2 potentially explosive atmospheres and are manufactured according to customer specifications. The gas preheater consists of a process gas coil and an electric heating bundle, which are cast in aluminum. The process gas flows through the coil and is heated by the aluminum block, which serves as a heat carrier. This type of indirect electric heating allows a very precise and consistent temperature control. Costly pressure vessels and the associated costs are eliminated.
The gas preheaters can be used for all gaseous media (air, natural gas, technical gases, fuel gases, steam) and low mass flows, at the same time high pressure (up to 300 bar).
In general, gases cool down upon expansion while they heat up during compression. These include carbon dioxide natural gas and air. The Joule-Thomson effect occurs when a gas or a gas mixture undergoes a change in temperature when the pressure changes, eg during the relaxation after a pressure regulator. In order to avoid icing or condensate deposits, thermal energy must therefore be used to heat the gas upstream of the pressure regulator. For this purpose this device is optimally suited.
