ECOFIT centrifugal fans for hot air are specially designed to convey air at very high temperatures, up to 150°C for GRA and GTA models, and 300°C for DTR models. Thanks to their impeller mounted on an outgoing shaft and a robust design based on our industrial expertise, they provide a reliable and high-performance solution for the most demanding thermal applications.

Technology designed for hot air

Unlike conventional compact fans, ECOFIT DTR, GRA, and GTA fans have a remote motor, which allows them to:

• Keep the motor out of the hot air flow
• Ensure good thermal endurance
• Guarantee continuous operation at temperatures up to 150°C for GRA and GTA models, and 300°C for DTR models

This unique architecture offers a major advantage: the hot air flow is supported by the backward impeller (DTR) or forward single inlet impeller (GRA and GTA), while the motor remains in a temperate zone (up to 70°C for DTR, and 50°C for GRA and GTA), significantly increasing the overall service life.

Performance, reliability, and compactness

ECOFIT DTR, GRA, and GTA centrifugal fans are available in several sizes and turbine types:

• impellers with diameters ranging from 180 to 225 mm for DTR models, and from 120 to 180 mm for GRA and GTA models
• stainless steel (DTR) or galvanized steel (GRA and GTA) impellers suitable for high temperatures

Our hot air fans are therefore the solution for manufacturers looking for a reliable, durable and easy-to-integrate high-temperature fan.

High-temperature applications

ECOFIT DTR, GRA, and GTA fans are widely used to transport hot air in critical environments such as:

• Food processing: cooking, heating, or maintaining food temperature
• Hot air units: essential reliability for air circuits heated between 100°C and 300°C.
• Climatic chambers and test chambers: uniform air circulation, thermal stability, continuous operation.
• Industrial ovens and low-temperature furnaces: internal ventilation, heat homogenization, mechanical resistance.
• Thermal OEM applications: integration into systems where compactness, endurance, and efficiency are crucial.
