Katherm HK P

Katherm HK P units impress with their short circuit-optimised air discharge flow, which guarantees uniform temperature distribution and excellent comfort. Thanks to the special layout and air routing within the trench, the air rises higher up the façade, mixes and penetrates deeper into the room. Flow-optimised roll-up and linear grilles underpin this effect. Compared to conventional systems, Katherm HK units thus offers more efficient output and a more comfortable indoor climate.

Katherm HK P units also guarantee a pleasant indoor climate in cooling mode as well. Draught-free cooling is ensured, thanks to low leaving air speeds and optimised air routing. The cooled air rises up the façade, forming a spreading drum of air that effectively flows into the room. This optimally shields the façade and simultaneously cools the room in an energy-efficient manner.

The HK P trench units are hygiene-compliant according to VDI 6022. Condensate pump, connection and tray are built into the floor trench. Push-in connectors enable simply removal of the tangential fan, allowing the condensate tray to be completely removed for thorough cleaning. This design ensures hygienic and user-friendly handling.

With Katherm HK P units, we rely on sound-decoupled tangential fans, which are installed with a special coupling/ball joint system to ensure minimum noise levels. The fans can be dismantled for maintenance without tools – simply and quickly. So your rooms remain pleasantly quiet, and maintenance can be done in a matter of minutes.

We offer tailor-made solutions for trenches and grilles adapted to every individual building architectural design. Select from mitred corners, curved designs, angles, diagonals and column cut-outs. Different grille versions and frames are also available. Ask for our advice to find the optimum solution for your project!

We carefully protect your Katherm HK systems during transport and assembly. Every trench is provided with environmentally-friendly paper cover to prevent it from becoming soiled during construction. We also offer an optional factory-fitted wooden cover for additional protection in the early interior fit-out phase. We supply the grilles separately and securely packed to guarantee their quality.

The heat and cooling outputs of the Katherm HK are measured in accordance with the test standard DIN EN 16430, Parts 1 to 3, a standard that specifically takes into account the installation conditions for trench systems. Our freely accessible calculation programs provide for precise design of the trenches, including calculation of heat outputs, mass flows and water resistances. This gives you reliable performance data for your project planning.

Immediately after calculating your Katherm HK performance data, we create a technical data sheet with all the information about your configuration. Simply download and you have all the product details, descriptions and technical drawings ready – clearly arranged and specially tailored to your project!

We look at the environmental impact of our products over the entire life cycle – “cradle to cradle”! This results in Environmental Product Declarations (EPD). EPDs can be easily submitted for all common building sustainability certification systems, such as DGNB, BREEAM or LEED, and are available in the Download area. In addition, the product is registered in the building products platform DGNB Navigator.

The new modular parametric design of the Katherm HK P comprises three parts: connection, power and expansion module. Around 12,000 different versions are available for optimum adaptation to the space available along the facade and to maximum output, thanks to the new parametric approach 100 mm incremental dimensions of the power module.

The connection module contains the electrical junction and control box, the continuously variable EC fan motor, the water-side heat exchanger connection and the waste water-side condensate connection with optional condensate pump. Valve kits for 2-pipe and 4-pipe connection are also available on request. All electrical components are arranged and wired in the junction box The connection module thus combines all interfaces to the electrics, heating and waste water systems on one connection side and thus ensures straightforward and time-saving wiring and connection.

The new power module significantly increases the performance of the heat exchanger. A single high-performance drive motor drives a continuous string of tangential fans via a newly developed and innovative coupling system. This cascading prevents power losses due to empty spaces and ensures a uniform flow along the entire length of the convector. The use of fewer, but more powerful motors, reduces resource consumption, as well as energy costs and the susceptibility to errors in projects. Thus, the system offers a sustainable and powerful alternative to conventional solutions with several individual fans.

The newly designed Katherm HK maximises output with minimal noise by optimising the use of space within the floor. Depending on the model, the components are arranged efficiently: with 4-pipe models, the right-hand area of the trench is used for the additional heating mode valve connection, while with 2-pipe models, this area is reduced to a minimum. This flexible design enables the units to be tailor-made to conditions on site and ensures optimum use of every centimetre of the trench system.

The heat exchanger has a connecting internal thread and is secured with an anti-torsion device, which also acts as a splash guard during venting. We offer a wide range of pre-settable Open/Close valve kits and also differential pressure-independent valve kits for smaller or larger water flow rates with corrugated pipes. All models can be factory pre-equipped to save time, in which case only press-fit connections at the copper end piece of the corrugated pipe are required on site.

Each Katherm HK P features an integrated condensate tray for safe condensate drainage in cooling mode. Condensate is either drained along a natural gradient of using an optional condensate pump, which can be supplied separately or factory-fitted. There are significantly fewer individual components of the new condensate pump. In the new Katherm HK P, the float switch and condensate motor are accommodated in a compact housing. The unit is supplied with a newly designed connection bend to the condensate tray. This saves assembly time and makes it easier to install waste water and electrical systems. The condensate pump continuously adapts to the required power requirements and is extremely quiet. A plug-in power supply and error message for ease of maintenance are pre-installed.

The ready-wired junction and control box is design for fast and safe electrical wiring. A built-in cable duct ensures clean and safe cabling.
