Hot gas centrifugal fan
Our experts engineer each industrial centrifugal fan to match your process conditions and specific requirements.
for conveying media at up to 1,000 °C
In production processes with ventilation systems, fans are usually a decisive factor.
Where high temperatures occur on site, hot gas fans are used to convey the media. Their design and the materials used allow them to operate reliably even in high-temperature zones.
Thanks to special design measures and high-quality materials, Scheuch COMPONENTS hot gas fans convey media at up to 1,000 °C. This makes it possible, for example, to equip a heat treatment plant with heating, annealing and cooling zones from a single source.

What are the distinguishing features of hot gas fans?
Their special design and the use of materials that withstand high thermal loads allow media to be conveyed in the high-temperature range. Suitable cooling methods also enable safe continuous operation.
Different drive types are used depending on the impeller diameter and the intended application. Depending on the model or type, hot gas fans offer the following advantages:
Compact design for cramped production sites
Flexible application options at operating sites with challenging thermal loads
Models that are scalable to the conveyor temperature and air circulation
Where are hot gas fans used?
A standout feature of hot gas fans is their ability to be used flexibly in a range of applications. They are generally used in high-temperature zones. The areas of application can also be related to specific industries, such as:
Air circulation in heat treatment furnaces for metals, glass or bricks
Recirculation fans for aluminium melting furnaces
Conveying of exhaust gases from combustion plants or test benches
Other hot-air and hot gas applications
What criteria should be used to select a hot gas fan?
Depending on the required function and the temperature range, you can choose between different designs and sizes of hot gas fan. Probably the most important criterion is the temperature of the conveyed medium on site. In terms of function and safety, the materials used are another decisive criterion.
To ensure that our products withstand high loads over the long term, we use selected Cr-Ni steels and nickel-based alloys. These components are processed with the greatest care at our main plant in Aurolzmünster (AT). A well-designed cooling and ventilation system is also an essential selection factor for low-maintenance operation over the long term.
How do hot gas fans achieve a controlled & uniform flow?
Numerical simulation processes can be used to check and optimize the desired effects in advance. Scheuch COMPONENTS uses flow simulations to optimize the inflow of our hot gas fans. The resulting controlled flow plays a significant role in the quality of the heating processes and, importantly, the manufactured batch.
Furthermore, this technology makes it possible to use the energy supplied by the fan as efficiently as possible. The flow control system, for example, can be adapted to the spatial conditions in the kiln with the aid of flow simulations. This reduces high-speed gradients and prevents dead zones.
How can fans be protected even at high medium temperatures?
Our hot gas fans are produced using heat-resistant metal alloys, effective high-temperature greases and mechanical cooling components. Additional thermal insulation can be used as an option to shield casing surfaces against extreme temperatures or prevent possible heat loss.
Independently of fan operation, active additional cooling can also help protect particularly vulnerable components such as rolling bearings if required, even after the fan has been switched off.
What are the advantages of hot gas fans from Scheuch COMPONENTS?
We have many years of experience in the field of centrifugal fans. Continuous development of our product range ensures that Scheuch COMPONENTS hot gas fans prove themselves in practice even in extreme operating conditions at temperatures of up to 1,000 °C. We design the geometry of the impellers used in our hot gas fans for the specific application, optionally without housing or guide plates. We can also equip your site with a complete heat treatment plant including heating, annealing and cooling zones from a single source. For sites with high thermal risk, we also offer further components as additional and safety equipment for centrifugal fans.
