A corporate enterprise of Achter Elektronik AG Meanwhile, we speak about control cabinet climate control instead of control cabinet heating:Heating and/or cooling. This includes temperature control, control of humidity, and also com- bined control of temperature and humidity. Varied fields of application show that this subject is not only prevailing with regard to controlcabinets: Control cabinets, automation, traffic and motor vehicle technologies, telecommuni- cation, switching and control systems, control cabinet distributor systems, switch room di- splays in power plants, in mining and...

A corporate enterprise of Achter Elektronik AG > General A more uniform heat distribution is achieved if the heater is installed within the lower third of the cabinet. Coolers however, should be installed in the upper area inside the cabinet. > The natural convection of heating air should not be disturbed by extreme packing density of installed built-in devices. Efficiency and heat distribution can be optimized by implementing circulation fans, complete fan heating systems, or by installing small ventilators. (See catalog pages 21 / 23) > Because of high surface temperatures, no...

A corporate enterprise of Achter Elektronik AG Our heaters consist of ceramic heating elements, built into an aluminum enclosure designed to thermo-technical specifications, and include an on-off bimetal temperature controller. Resistors and output curves of that heating system show linear characteristics. 1) The built-in temperature controller ensures operational reliability.2) Due to the built-in temperature controller, there are no high surface temperatures thatcould influence or damage the built-in devices in their functional reliability.3) The built-in temperature controller is set to...

A corporate enterprise of Achter Elektronik AG Our heaters consist of specifically designed aluminum bodies with inserted PTC elements.These elements are also called thermistors and consist of doped semiconductor materials. 1) PTC heaters are self-controlling with a dynamic heat-up phase. 2) This heating principle can be utilized within a wide voltage range (110 V to 265 V). 3) With types P-25 (page 21) and P-80 (page 23), it is possible to install an additionalfan. Thereby you achieve a more uniform heat distribution and higher efficiency. 4) Regarding tightly packed built-in devices or...
