Special Heating and Thermal Technologies for Industry and Halls
For industrial and hall heating, various specialized systems are available that efficiently, economically, and demand-orientedly heat large and high spaces. Since 2024, legal regulations require an increasing share of renewable energies such as green electricity, hydrogen, or bio-liquefied gas, which can be implemented particularly efficiently using radiant heaters (infrared), surface heating systems, as well as modern heat pumps and hybrid systems that can flexibly adapt to individual process and temperature requirements.
Infrared heating
These systems do not heat the air but directly warm the objects in the room, such as machines, components, and people. These objects store the heat and slowly release it again. This creates a comfortable, draft-free indoor climate with reduced dust circulation and low operating costs.
Advantages:
- High efficiency
- Short warm-up times
- Zonal heating possible
- Pleasant warmth sensation
- Quiet operation
- Reduction of energy consumption and CO2 emissions
Warm air generators
Warm air generators draw in air, heat it using gas or oil, and then direct the warm air straight into the space to be heated. Modern units use condensing technology for higher efficiency.
Advantages:
- Ideal for halls with frequent air exchange, such as those with large doors
- Can be combined with other ventilation systems
Surface heating systems (e.g., underfloor and wall heating)
Surface heating systems include underfloor, wall, or ceiling heating, in which flat piping systems embedded in building components are supplied with warm water or air. These systems heat the components, which in turn emit radiant heat across a large surface.
Advantages:
- Even heat distribution
- Low supply temperatures (e.g., 35 °C)
- Can be combined with heat pumps, also suitable for cooling
- Particularly cost-effective when used with renewable energy sources (e.g., heat pumps)
