Tandem · Kampmann
Two coordinated air streams for the entrance.
Tandem air curtain technology combines air streams to help separate indoor and outdoor conditions at an entrance. It is suited to commercial buildings where doors open frequently.
Designed around your project
- Select the model and discharge arrangement to suit the doorway width and mounting height.
- Coordinate heating supply and controls with the building operating concept.
- A suitable maintenance arrangement keeps air inlets and internal components accessible.
What matters when selecting the unit?
Existing Tandem 300/385 models may differ from current units. Confirm the precise generation and installation drawing; doorway exposure and pressure differences affect performance.
Product selection with TDC
Send us the room layout, required heating or cooling duty, system temperatures, available installation space and controls requirements. We will help select the equipment and suitable accessories.

Dimensions and available versions
Tandem 300: width 820 mm, height 300 mm, lengths 1,250, 2,000, 2,500 or 3,000 mm. Tandem 365: width 985 mm, height 365 mm, lengths 1,250, 2,000 or 2,750 mm. Verify the exact current version; older Tandem 385 installations may differ.
Technical details
An unheated leading stream helps protect the heated stream from mixing with outside air. Discharge elements can be adjusted up to 20°. Hydronic low-temperature operation needs the correct coil selection at the design conditions.
Installation and project planning
Select the unit and mounting arrangement for the entrance. KaControl MC or electromechanical control is version-dependent. Multiple units require suitable connection and control equipment.

In addition to the warm air curtain, a separate fan group produces an unheated primary air curtain that has a greater penetration depth and acts as a "back-up" air stream for the warm air curtain. At the same time it acts as a separately layer towards the cold outside air: cold outside air cannot penetrate in and warm air cannot escape.
The penetration depth and screening effect are both increased by the contraction of the primary air stream and the warm air stream without this needing additional energy. This also means that the units can even be fitted at a greater height.
An energy-saving of approx. 38 % is possible by the combination of:
- Increased penetration depth caused by the Coanda effect
- Unheated primary air stream
- A resulting smaller volume of warm air curtain
