Screw-in radiators for industrial and commercial applications
Screw-in heaters are the straightforward solution for heating liquids in industrial and commercial applications. They are suitable for hot water storage tanks and can be easily retrofitted into existing heating, cleaning, and heat exchanger systems. In addition to standard models that are available from stock, we develop customized versions that are precisely tailored to the technical requirements of our customers.
Our screw-in heating elements consist of three tubular heating elements that are soldered into a cartridge plug. Sensor tubes enable the integration of a suitable temperature control directly in the connection head. Controllers and limiters switch without a power contactor, which simplifies installation.

Delivery times for screw-in radiators
The screw-in heating elements listed in the type overview are available from stock.
Screw-in heaters are always installed horizontally. Sealing is achieved using an O-ring or liquid seal. Both variants must be approved in accordance with DIN EN DVGW up to 150°C. The models listed are designed for unpressurized systems. For closed water heaters, an STB safety limiter is required in addition to the regulator in accordance with the Pressure Equipment Directive 2014/68/EU. Our models with the item numbers 100-XXXX-03 meet this requirement. A safety valve must also be provided by the customer on site.
Our screw-in heating elements are made of corrosion-resistant stainless steel. We use material 1.4529 for the pipe jacket and material 1.4404 for the cartridge plug. A cover made of material 1.4301 protects the built-in switching devices. Our screw-in heating elements have protection class IP54 and bear the CE mark.
Can a screw-in heater also be operated in combination with a photovoltaic system?
Can screw-in heating elements also be used in aggressive or chemically contaminated liquids?
Use in aggressive media is only possible to a limited extent, taking into account the specific conditions.
Can individual screw-in heaters be designed for continuous operation at very high temperatures?
What options are available if the installation space is very limited?
Can existing systems be retrofitted with our screw-in heating elements?
Yes, in many cases this is possible, including through the use of thread adapters.
