Product Portfolio
Flange immersion HEATERS | FHK series
- Flange heaters from Herbst Beheizungs-Technik are particularly suited for heating up fluids and gases.
Electric flange heaters are manufactured with highly compacted tubular heaters (Ø 8.5 / 11.5 / 12 / 16) which are bent into a U-shape and welded or hard-soldered into flange plates DN 50 up to DN 600.
The flanged heating elements enable high heating performance within the smallest space.

Construction
-
- 法兰与影响以及浸入式加热器制造hly compacted tubular heaters [1] (Ø 8.5 / 11.5 / 12 / 16 mm) which are bent into U-shape and welded or hard-soldered into flange plates [2] from DN 50 up to DN 600.
The stable positioning of the heating elements is secured by means of laser-cut spacer discs [3] which are also used as baffles. This construction element provides an adequate flow-direction of the operating fluids and gases and prevents undesired accumulation of heat.
The connection housing [4] is mounted directly on the flange plate. If a cooling section [5] is required the enclosure can be installed with sufficient distance to the heating zone.

Processing
-
- 法兰加热器被证明每天在不同的职业cess installations. Electric heating elements combine properties such as efficient heating, long service life and low maintenance costs.
When dimensioning heating elements, particular attention is paid to finding the best compromise between technical feasability, quality and economical aspects.
Flange heaters have to suit customers' application - in size, shape , performance, chemical and thermal resistance, controls and protective systems. To ensure this, it requires expert knowledge.

Cartridge heater
-
- Heating flange with cartridge heaters
Flange plates equipped with heating cartridges are particularly suitable for use in large tanks. The welded-in steel tubes contain exchangeable ceramic heating elements which can be replaced individually without draining the fluid.
The steel tubes have selectable diameters of Ø 36 mm, Ø 42 mm and Ø 52 mm. The TIG welding process is mainly used to connect them with the flange. The flange heaters should be mounted horizontally.
Similar to standard flange heaters the electrical connection is contained in a housing directly on the flange plate. Control cabinet with protection system IP54 and IP65, integrated thermostat and temperature limiter are available as options.
Circulation heaters
- Circulation heaters - Industrial process heat
Circulation heaters are very suitable for an efficient heating of fluids and gases. The petrochemistry, shipbuilding, medical technology, industrial cleaning technology, plant construction and process engineering are typical areas of use.

Air HEATERS | LEH series
- Design with finned tubular heaters
为了阿btain optimum heat transfer and heat distribution the tubular heaters can be supplied with finns. The finned heating elements enable higher power outputs in often smaller installation spaces.
Design with tubular heaters
Air and duct heaters are typically used to heat process gases and air in industrial applications up to a temperature of 800 °C.
Air heaters are designed to obtain optimum heat transfer as well as good heat distribution.
Depending on the particular process parameters the electric air heaters can be designed and built with single or double U-shaped heating elements or in customer-specific shapes.
When dimensioning the air heaters particular attention is paid to select the permissible watt density and the maximum temperature of the tubular heating elements.
While avoiding overheating and subsequent damages the air and duct heaters are permanently and reliable ready for use.
The connection housing can be mounted with a suitable cooling zone and if required with further protection by thermal insulating material.
Herbst Beheizungs-Technik provides their air duct heaters ready to connect and the terminal housing can be supplied with protection class IP54 and IP65.
