Warm air is lighter and always wants to rise, which makes driving it downwards a genuinely hard engineering problem. The answer lies in precise blade control across a range of 0° to 90°: the blades form a dense vertical jet that cuts through the height of the building and delivers heat right down to floor level.
How the hot air layer is broken up
- Effective recirculation. Quiet, energy-efficient EBM-papst fans pull the overheated air down from ceiling level and return it to where people are working; smooth 0–100 % modulation matches output to what the building actually needs.
- Vortex distribution. The swirl gives the stream stability and reach, so it drives through the cold layers all the way to the floor instead of dissipating early.
- Precise aim. Adjustable blades on Belimo actuators steer the warm stream vertically downwards and keep adjusting as conditions change.
- Maximum heat transfer. The copper-and-aluminium coil heats the space quickly while moving 25–30 % less air than conventional systems.
Heating variants
| Energy source | Series |
|---|---|
| Water (boiler house, district heating, heat pump) | OXA-D |
| Electricity (heating elements) | OXA-ED |
| Gas (integral burner, 98.9 % efficiency) | OXA-GD |
| Refrigerant (condensing unit / VRF) | OXA-530N/670N |
| Side discharge, water | OXA-SD |
Because the heat source is a module rather than a fixed part of the design, the equipment drops into whatever energy infrastructure the site already has without changing the architecture of the system.
