The Centrifuges are used for the determination of the bitumen percentage in bituminous mixtures. All models comprise a removable precision-machined rotor bowl housed in a cylindrical aluminum box. The bowl is driven by an electric motor fitted with an AC drive (inverter) with the double function of speed control up to 3600 rpm regardless of the frequency (50 or 60 Hz) and electrical breaking. The centrifuge can be set for the automatic speed ramp up to 3600 rpm and will stop in 10-15 seconds.
The cover is precisely machined and fitted with a solvent resistant gasket to avoid leakages.
The control panel includes: Start/Stop button and speed control knob.
