The new range of heaterSteam immerse heater humidifiers includes models producing from 2 to 60 kg/h of steam, and can operate on drinking water or demineralised water. heaterSteam features exclusive technological solutions, such as the electric heaters embedded in corrosion-proof aluminium alloy casting with a large heat exchange surface, and built-in temperature sensors to prevent overheating. For each model there are two variants: basic and “full option”. The full option units have heat insulation around the boiler for maximum energy savings, and Teflon coated heating elements to facilitate the separation of lime scale. The heaterSteam range is available with 3 types of control: H, modulating with built-in controller (from active humidity probe); T, with temperature control (from external probe); C, for simple ON/OFF control . The models from 2 to 10 KG/h have a cylindrical stainless steel boiler, which is easy to remove for cleaning; The larger models, from...

Immerse heater humidification is becoming increasingly required in work specifications where: Humidity must be controlled precisely (museums,   laboratories, clean rooms); Water quality is not constant or is problematic (for example, aboard ships); Periodical maintenance needs to be minimised (using demineralised water).      Immerse heater humidifiers, unlike immerse electrode units, can operate on demineralised water, as they do not exploit the electrical conductivity of the water. Periodical maintenance can therefore be greatly reduced, due to the minimum formation of lime scale. Weighing against this, the resistive elements must always be completely immersed in the water, to avoid overheating, unlikely the situation with electrodes, in which the water level is adjusted to modulate the flow-rate of steam. The operation of an immense heater humidifier then requires water level sensors to ensure complete immersion of the electr...

Carel's extensive experience in the humidification sector has been used to develop the gaSteam range of gas-fired humidifiers, exploiting an energy source that is more economical then electricity. The humidifiers now have updated controllers, and the smallest model has now been upgraded to 45 kg/h (still below the 35 kW limit). The range thus now features the 45 kg/h, 90 kg/h and 180 kg/h models. Carel gas-fire humidifiers can run on both natural gas and LPG: the changeover is made by simply modifying a number of parameters, without the need to replace any parts. Cost effectiveness To generate 1 kg of steam at atmospheric pressure, considering all the various factors, requires around 750 Wh of energy, either electrical or from other sources. One of the main factors when choosing solutions in the field of isothermal humidification is therefore energy cost, particularly for heavy-duty applications. Gas can be considered an ideal solution in terms of energy source, ho...
