Katherm QK nano

Fan-assisted trench heating with EC technology.

Katherm QK nano
Your benefits:
  • Extremely reduced dimensions

  • Whisper quiet, high performance

  • New filigree FineLine grille


  • Shallow trench height of only 70 mm and trench width of only 165 mm enable maximal use of the floor space.
  • A matching edge profile for a perfect design with every FineLine grille
  • A 24 V / electromechanical control option or alternatively the KaControl control system are available
  • Can be integrated into KaControl networks or building automation system, such as KNX, Modbus or LON


  • Effective cold air screening of full height windows
  • Whisper-quiet tangential EC fan for balanced airflow over the convector length, resulting in high heat outputs at low sound emissions
  • Unique high-performance convector optimised for ultra-low LPHW-Temperatures.
  • Anti-twist device for the LPHW- connection prevents damage to the convector when fitting the valves; valve connection sets optional as accessories


  • All areas of buildings with limited floor build-up for trench heating solutions in which effective heating and cold air screening is required.
  • Ideal for residential and commercial applications
  • Clear view and feel good temperature in front full heigth glazing



The combination of EC technology and KaControl stands for maximum energy efficiency, as the advantages of the EC fan can be ideally used in operation thanks to the continuous fan control by the KaControl technology.


At the same time, the air conditioning system that is operated at low fan speed to meet demand is advantageous especially in residential properties, offices and hotels. The ability to reduce the fan speed and thus also the air volume of the fans is of huge significance in terms of noise levels.


Kampmann Katherm QK nano with KaControl control are fully wired and delivered ex-works complete with all of their electrical components fitted. An effective parameterisable microprocessor provides all of the requisite functions, thus every Katherm QK nano has its own "intelligence" and can be operated in groups via Kampmann-t-Lan or CANbus networks.


KaControl Katherm QK nano can be fitted with plug-in communications interfaces for single room control or for connection to higher-order management systems. Every basic unit therefore has the potential to be integrated into a technical building automation network.




  • Valve actuation for 2- and 4-pipe systems
  • Temperature recording via KaController or external room sensor
  • Automatic continuous fan control according to room temperature
  • Maximum fan speed set via potentiometer on the PCB
  • Noiseless valve actuation via electronic relays
  • Motor fault evaluation, condensation alarm
  • Room frost protection function by monitoring of room temperature in every state to a limit value of 8°C
  • Frost protection function by fitting optional clip-on temperature sensor
  • Actuation by means of 0-10 V signal from an external BMS
  • Connection to open BMS system by optional interfaces (BACnet, Modbus)

System configuration

Control zones with up to 6 Katherm QK nano can be connected to a KaController via simple 2-wire bus connection.


Control zones with up to 30 Katherm QK nano can be connected to a KaController via a CANbus connection.
