The Katherm QK nano stands out with its top performance in a compact format. It provides heating with tangential fans in low temperature operation.
The Katherm QK nano fits here with a channel height of only 2.76 in. Ideal for rooms with high heating demand.
Katherm QK nano units are acoustically optimized and fit perfectly in acoustically sensitive rooms. The sound power level is measured in accordance with EN ISO 3744 in a semi-anechoic sound measurement chamber.
The channel height of the Katherm QK nano is only 2.76 in. Depending on the control version, different channel lengths are available. This enables (almost) unrestricted use of the room. As a rule, it is installed with little clearance directly at the facade.
The Katherm QK nano stands out for its compact dimensions, ideal for rooms with high heating demand but only limited installation space. The compact EC cross-flow fans allow a channel height of only 2.76 in. This enables easy installation in raised floors or screed. Despite the low height, Katherm QK nano units can cover high heat loads in the room.
The Katherm QK nano is suitable for use with a heat pump or another low-temperature system. Thanks to fan assistance, especially at low system temperatures with warm water, you quickly achieve the 3-4 times the output of conventional radiators. This reduces your energy demand and heating costs and, ultimately, greenhouse gas emissions as well.

The FineLine grille was developed specifically for the Katherm QK nano. A rigid grille made of flow-optimized profiles as a orthogonal grille (FineLine Q) or linear grille (FineLine L).
Available in powder-coated steel in the colors RAL 9006 (white aluminium), RAL 9007 (grey aluminium), RAL 9005 (black), DB 703 (basalt grey) or in stainless steel.
Thanks to the valve connection, a fast and easy installation of the Katherm QK nano is possible on site. Height adjustment screws and step-resistant height adjustment feet are supplied as standard. This reduces installation time and therefore costs.
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 the units are often installed in the building at an early construction stage, the grille can be replaced at the factory with a wooden installation cover for their protection for an additional charge. The grilles are then supplied separately packed.
Adapt the product to your requirements – these options are available for selection.
The grilles are available in various colors.

With our free calculation program, you can find the product with the right performance data for your project in just a few steps. You can then download the official technical data sheet with your individual project values as a PDF.
We assess the environmental impact of our products across their entire life cycle („cradle to cradle“) and publish the results transparently in our Environmental Product Declarations (EPD). These EPDs can be easily integrated into leading building certification systems such as DGNB, BREEAM, or LEED and are available in the download section.
