Katherm QK

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.

It is technically relevant 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.

We offer various solutions for the control and regulation of our units, which can be used depending on the application and requirements:

Electromechanical control

This variant is ideal for simple applications. All integrated actuators are factory-wired to terminals and can be connected to our electromechanical accessories such as thermostats or external controllers.

KaControl MC1

Our comprehensive comfort control offers extended control options for individual rooms or appliance groups. It can be operated either via a touch display or a web interface. Thanks to on-site 0-10 V control or common communication protocols such as Modbus RTU & TCP, BACnet and KNX, this solution is ideal for all BMS applications.

• The heat outputs were determined in accordance with DIN EN 16430 (Part 1-2) under realistic conditions on the basis of DIN EN 442.
• The standard regulates the performance measurements in uniform standards, especially for trench convectors.
• Ensuring uniform comparability of different units.
• Safety in planning and design.

• 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 shielding on glass surfaces to avoid condensation
• 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.

Additional supply air models (ZL) are available for the Katherm QK, enabling additional conditioned supply air to be fed into rooms.

Features:

• Trench length 400 mm
• different nozzle sizes/designs are possible
• Regulation of the air flow via built-in sliding elements
• Low leaving air velocities, hence pleasant level of comfort.
• Low sound development when correctly designed.
• low investment and maintenance costs
• No wear parts/no electrically rotating parts.

The slider can be moved into different positions to set the required volumetric flow for the room on the supply air module.

• 4 different slider positions are possible (100%, 75%, 50% and 30% open).
• Reading the air volume flow, sound level and pressure losses from the diagrams in the technical documentation regarding comfort.
• Intermediate values can be interpolated.
