Air heaters

What is an air heater?

The space to be heated influences the choice of the appropriate air heater. In industrial halls and large spaces, supply air heating is often the best solution, whereas in confined spaces, a recirculating air heater may be considered.

Air heater selection

We assist in selecting an air heater that meets the requirements of the application. Ask our contacts for more information.

Supply air heating – devices for heating replacement air flows

When an industrial hall or another large space requires a significant amount of replacement air, for example due to processes that heavily soil the air, centralized supply air heating is often the most sensible way to implement heating. The advantage of gas-fired supply air heating is its excellent efficiency, and the supply air heaters we provide comply with current energy efficiency directives.

We supply the MARK GC series supply air units that are installed adjacent to the wall, with the heated replacement air brought from outside directly to the unit via a short duct. GC heaters are also suitable for decentralized supply air heating implemented with multiple units. The exhaust gases from the heaters can be directed straight into the heated space or, if necessary, channeled out through the wall. Because the devices have a completely closed air circulation, they are also well-suited for spaces where the air is dusty or otherwise dirty.

Supply air units are typically suitable for heating large air flows, and thanks to a powerful radial fan, the supply air can be conveyed through a duct.

Recirculating air heaters

Recirculating air heaters are particularly suitable for low spaces with many shelves or other structures that compartmentalize the area. A recirculating air heater is easy to install, for example, high on the wall where it does not interfere with other activities. The fuel for our imported air heaters can be natural gas or liquefied petroleum gas. The exhaust gases can be directed either straight into the heated space or, if necessary, away from the space. In the summer, the heaters can also be used solely as blowers. The unit power range of recirculating air heaters varies from 15 kilowatts to 150 kilowatts.

Axial fans are used in recirculating air heaters, which circulate the air in the space without causing excessive and disruptive blowing.
