Katherm ID

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.

2-pipe system

With this design, the entire heat exchanger surface is available for temperature control, depending on the medium currently present in the pipe system (cold or hot water). Switch-over between heating and cooling takes place centrally via the building management system. This variant is particularly suitable for applications with seasonal switch-over and reduced installation effort.

4-pipe system

This version is suitable for sophisticated air conditioning concepts in which each room zone or unit can be switched over individually between heating and cooling. By routing the heating and cooling medium separately, the system offers maximum flexibility and comfort - ideal for buildings with changing usage requirements.

This configuration has a direct influence on the induction effect and the sound power of the unit. For applications with a low primary air volume, the number of nozzles is reduced in order to achieve the highest possible induction effect with a low air supply. For higher primary air volumes, more and larger nozzles are used to prevent acoustic impairments. The induction effect remains at a high level. The appropriate nozzle design should be selected depending on the air volumes, room acoustics and thermal requirements.

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.

• The heat and cooling outputs were determined in accordance with DIN EN 16430 (Parts 1-3) under practical conditions based on DIN EN 442.
• The standard regulates performance measurements in uniform standards, especially for underfloor convectors.
• Ensuring uniform comparability of different devices
• Safety in planning and design

• directly on the façade, without a larger distance
• Provide expansion joints on site to prevent compression by screed, for example.
• Air outlet arrangement on the window side.
• The rising air forms an air roll that ventilates draught-free into the room.
• Optimum shielding of the facade as well as cooling and heating of the room.

The current guidelines of DIN EN 16798 and DIN EN ISO 7730 must be taken into account when planning Katherm ID.

The following values are recommended:

Cooling case:

• Supply air discharge temperature <4K below room temperature
• Outlet velocity <1.2 m/s
• Distance of the supply air duct to the occupied zone >1 m

Heating condition:

• Supply air discharge temperature 20-26 °C (not lower than room temperature)
• Outlet velocity <1.5 m/s
• Distance of the supply air duct to the occupied zone >0.5 m.

Katherm ID are designed for:

• Short-circuit-optimized air outlet on the façade
• Even temperature distribution and comfort in the occupied zone

• Various air volumes can be applied to the Katherm ID.
• Matching nozzle plates available for different supply air volumes.
• The nozzle plate can easily be replaced with another nozzle plate to adjust the air volume.

The Katherm ID trench convectors are equipped with the standard grilles

• Aluminum, anodized
• Stainless steel

available.

You can also choose your suitable grating from the following variants:

• Aluminium in the variants natural anodised, brass anodised, bronze anodised, black anodised, bronzed and coated DB 703
• Stainless steel, polished
