Katherm HK

Trench technology for heating or cooling

Katherm HK is low-noise and energy-efficient and is used for heating and cooling. It operates with tangential fans.

Heating and cooling

With Katherm HK trench technology, energy-efficient and noise-optimized heating and cooling is possible at all system temperatures, including low-temperature and heat pump operation. They are suitable for all types of buildings in which, due to internal loads and solar radiation through large glass façades, a predominantly higher cooling load occurs.

Supply air connection

Take advantage of the possibility of introducing primary air into the building with Katherm HK - optionally via supply air modules or supply air ducts. The new Katherm HK P (height 160 mm, width 310 mm) features primary air connections with air spigots or air intake via the raised floor.

624 variants

Four trench widths and three width-dependent trench heights are available to choose from. Depending on the on-site requirements, 6 different product-specific lengths are available for all performance requirements in the 2-pipe and 4-pipe system.

Lengths: 915 – 3000 mm

Customized production

Custom-made solutions are possible for any building architecture with individual geometries. This applies to the trench and the grille. Available examples include:

  • mitred corners
  • curved versions
  • angles and slopes
  • column cut-outs
  • various grille variants
  • frame edges

Optimized air distribution in cooling mode

Katherm Hk glass facades

Use with high cooling loads

  • for rooms with high cooling load and special requirements for comfort
  • the units are generally arranged directly at the façade without any greater distance
  • cost-effective effective cooling, especially with large glass façades

Comfort in cooling mode

  • low air outlet velocities and an optimized air outlet ensure optimum comfort in cooling mode
  • cooled air rising at the façade forms an air roll and flows into the room without drafts
  • ensures the best possible shielding of the glass façade

Condensate drain

Every Katherm HK is equipped with a condensate tray that collects the condensate produced in cooling mode and drains it safely from the trench. Condensate removal is achieved by a natural fall or optionally by a supplied or factory-mounted condensate pump .

 

Minimum noise through acoustic decoupling

Katherm HK is used in acoustically sensitive rooms because the smooth-running tangential fans are mounted with acoustic decoupling thanks to the innovative combined coupling/ball stud system.

For maintenance purposes, the fan can be removed or installed without tools.

Protection during installation and construction time

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.

Control options

KaControl MC

The Katherm HK offers bidirectional communication for up to 10 units within a group/room via CAN bus with the integrated KaControl MC control. With KaControl MC, the unit can be easily integrated into common building management systems such as Modbus RTU, Modbus TCP, BACnet/IP and KNX-TP. 

Electromechanical control

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

Selection options

Adapt the product to your requirements - these options are available for selection.

2‑pipe system

Heating or cooling (central switch-over possible)

4‑pipe system

Simultaneous heating and cooling in different usage zones

Design grilles

Wide range of versions in material and color. Can be used on both sides. Shortenings and extensions are also possible.

Product finder

With our free calculation program you can find the product with the right performance data for your project in just a few steps. The official technical data sheet with your individual project values as a PDF download is then available.

Hygiene-certified

Thanks to its well-thought-out design, thorough cleaning in accordance with the requirements of the VDI 6022 hygiene guideline is easily possible. The condensate tray that can be pulled out toward the room enables complete cleaning of the tray. 

Life cycle assessment data (EPDs)

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.

ErP-compliant ventilation

Separate ventilation and temperature control with a hybrid ventilation concept: The combination of central ventilation via an AHU unit and decentralized air conditioning with pumped hot water and chilled water enables efficient heating and cooling.
