Unit heaters

choosing?

An air heater is a heating apparatus used in large industrial and commercial spaces. It takes in ambient air, passes it through a heat exchanger and redistributes it as a function of the configuration of the space and the desired level of comfort.

Applications

Air heaters are high-power heaters used to heat large-volume spaces such as industrial buildings, warehouses, workshops, sports arenas, etc.

Technologies

The three principal types of air heater differ according to their energy source.
- Hot water and steam heaters circulate hot water or steam through a heat exchanger coil.
- In electric models, the exchanger contains a resistance element.
- Gas heaters use a burner to heat the air passing through the exchanger.
Their blowers can be helicoidal or centrifugal.

How to choose

The range of on-site energy sources and regulations governing the activity in question will determine the choice of heater. A thermal study of the area to be heated, its size and layout will dictate the number, power and flow rate of the heaters.

Advantages

- Powerful
- Can heat large air volume
- Significant circulation
- Avoids thermal stratification

Disadvantages

- Slow to start
