Katherm QE

Trench convectors can be selected in different lengths (A) depending on the version, so that they can be optimally integrated into common window hinge systems.

The functional width (B) and height (C) allow individual adaptation to the floor structure and at the same time determine the performance of the trench convectors.

Continuous hinges can be realized using empty parts, column recesses, angles, etc.

Various grating variants are available for the cover, which ideally meet both functional and design requirements. Different materials can be selected depending on the application area.

In addition, different surface coatings and colors are possible in order to achieve a visual adaptation to the building architecture and interior design.

What is technically relevant is that the choice of material and geometry can influence the free air cross-section and thus have an impact on the performance of the unit. These effects are taken into account in the performance calculation.

The heat output and safety functions were determined in accordance with DIN EN 60335, Part 1, Part 2 - 30 and Part 2 - 40.

DIN EN 60335 regulates, among other things, the operating and functional behavior of:

• improper operation, e.g. covering the grate;
• overvoltages occurring in the grid;
• maximum surface temperatures, e.g. on the grate surface;
• Function of the safety devices;
• Moisture resistance.

• directly on the façade, without a large gap (A, B)
• provide expansion joints (1) on site to prevent compression by, for example, screed
• Arrangement convector on the window side, tangential fan on the room side
• effective heating and cold air shielding for glass surfaces
• Rising air forms an air vortex that flows into the room without creating a draft.

The units are equipped with quiet, sound-optimized EC fans.

Sound pressure and sound power levels are tabulated in the technical data.

The actual sound pressure level depends heavily on:

• the number of units;
• the acoustic properties of the room.

Recommendation: The design should always take into account the permissible sound pressure level in the room.

Two control concepts are available for controlling the Katherm QE:

• Control by a room temperature controller
• Control by an external BMS

In both concepts, the EC tangential fans are speed-controlled via a 0-10 V signal.

As soon as the EC tangential fans are switched on at any setpoint, the stepless heating output control goes into operation.

The right electric heat output is provided for every volumetric flow.
