Effective cold air screening

The Tandem increases comfort in the entrance area. Thanks to the preliminary air curtain, it improves effective cold air screening and reduces energy losses.

Preliminary and warm air curtain

A so-called tandem technology is built into the air curtain, generating a preliminary air curtain and a warm air curtain. The preliminary air curtain is not heated; it protects against energetically unfavourable turbulence in the warm air curtain. The separation of the two air curtains reduces the heating demand and leads to faster payback compared with conventional units as well as more climate-friendly operation.

Model sizes

The Tandem is available in two unit heights. Depending on the unit height, up to four unit lengths are available.

Mounting options

The unit can be mounted suspended with brackets on the wall or on the ceiling . The air discharge height is between 2.7 m - 4 m.

Several Tandem air curtains can be mounted as a visually continuous band using a connection set (accessory), or connected to one another.

Fast Maintenance

Maintenance is extremely simple: the large-area filter, including frame and intake grille, can be removed with minimal effort.

Also practical is the large revision flap. The entire underside of the unit can be opened in just a few simple steps.

Technical highlights

Air outlet

  • Adjustable air outlet rectifiers ensure a straight, low-turbulence air outlet.
  • They can be swivelled up to 20°.

Low temperature operation

  • For efficient use of a heat pump system, the air curtain can be operated with low flow temperatures.
  • The warm air curtain also benefits from this, as it reaches the floor more efficiently due to lower temperature differences.

Life cycle assessment data (EPD)

  • 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.

Control options

KaControl MC

The Tandem offers bidirectional communication of 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.
