Operational reliability

The Katherm QE offers a high level of safety during operation. This is ensured by the two-stage safety circuit and the grille fastening.

Electric heating coil

The Katherm QE offers a powerful electric heating solution for rooms with floor-to-ceiling windows – wherever hydronic systems are not practical or cannot be implemented.

Various lengths

The selection of sizes offers the right solution for every project.

The Katherm QE is available with a uniform trench width and height 
and is available in three trench lengths.

Custom-made solutions

Custom-made solutions are possible for any building architecture with individual geometries. This applies to the trench and the grille. 

Possible custom options include, for example:

  • Mitred corners
  • Curved versions
  • Angles and slopes
  • Column cutouts
  • Various grille variants
  • Frame edges

Matching roll-up grilles

Katherm QE units are supplied as ready-made heating trenches at screed height. We provide the matching Optiline roll-up grilles for every installation situation. The frame edge is also manufactured to match visually.

Protection during installation and construction

Our Katherm trench technology products are carefully packed in cardboard packaging for transport. The grille edge trim profiles are protected against damage by green plastic profiles. A sustainable paper cover prevents dust and dirt from entering.

As Katherm QE units are often installed in the building at an early construction stage, they should be covered on site with wooden boards or similarly stable material to protect them from mechanical damage.

Touch protection

The grille of the Katherm QE serves as touch protection. It is fastened at the factory and can only be removed with a tool.

Technical features

High heat output without hydronic hot water

  • Katherm QE units with electric heating coil are the ideal solution for rooms with floor-to-ceiling windows where the use of a convector with hydronic hot water cannot be implemented or is not economical.
  • The high heat output is supported by an energy-saving EC tangential fan while maintaining a low sound level.

High operational reliability

  • An integrated safety chain consisting of a safety thermostat and thermal fuse ensures safe operation with low grille surface temperatures in the event of improper operation.
  • The safety circuit is 2-stage (mechanical and electrical).
  • For touch protection, the trenches are also equipped with a factory-mounted grille fastening. 

Certified to CE and UL

  • The Katherm QE complies with the required safety guidelines and is certified to CE and UL
  • The measurement-based determination of the heat output characteristic curve and the safety functions, proportional to the control voltage, was carried out in consideration of the relevant standards.
