Our Thermo roof fans provide one of the widest ranges in the market. These roof fans can handle kitchen and industrial exhaust air up to 120°C air temperature, which ensures a safe and comfortable indoor climate.
Air volume from 540l/s – 15,555l/s (1940m³/h – 56,000m³/h)
DVG-T/H roof radial fans are suitable for daily ventilation of media up to 120°C.
Casing
The casing with integrated bird protection is manufactured from sea water
resistant aluminium. Base frame is made from ZM (Zinc-Magnesium) coated steel.
Motor
IEC flange motors outside air stream with efficiency class IE2, where applicable. 60 Hz power supply.
Impeller geometry
Radial impeller with backward curved blades manufactured from steel.
Output control
Speed controllable via frequency converter. Service switch on the casing.
Motor protection
Integrated PTC thermistors.
Casing
Casing manufactured from sea water resistant aluminium. Base frame with integrated inlet cone, manufactured from galvanised sheet. Includes bird guard manufactured from powder coated, galvanised steel.
DVNI with 50 mm acoustic and thermal mineral wool insulation.
Motor
Voltage controllable IEC standard motors and frequency converter controllable IE2 standard motors.
Impeller geometry
Radial impeller with backward curved blades.
Output control
Single phase motors can be speed controlled via a 5-step transformer. In addition, three-phase motors where indicated are step speed controllable via star-delta switching. IE2 motors can only be controlled via frequency converter.
Motor protection
Integrated thermal contacts or PTC thermistors with cables for connection to a motor protection switching device.
