Operational safety

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

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.

Wide range of variants

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.

Customized made-to-measure production

For every building architecture with individual geometries, custom-made solutions are possible. This applies to the trench and the grille. 

Possible examples include individual:

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

Matching roll-up grilles

Katherm QE units are supplied as ready-made heating channels 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 period

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 factory-mounted 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 in which the use of a convector with hydronic hot water cannot be implemented or is uneconomical.
  • The high heat output is supported by an energy-saving EC tangential fan while maintaining a low sound level.

High operational safety

  • 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 implemented in 2 stages (mechanical and electrical).
  • For touch protection, the trenches are additionally equipped with a factory-mounted grille fixing. 

Certified to CE and UL

  • The Katherm QE complies with the required safety directives 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 taking the relevant standards into account.
