Doll – Smooth-start-up devices for radiator heaters:

 

Normally motor drives are running up with full motor-power when starting-up a ventilator, the negative side effects are that vee-belts can't be instantly accelerated from zero to full-transmission operation, the vee-belts get shifting and are causing a squeaky noise.

Besides the acoustic disturbance a decreased vee-belt life-span is also resulting from wearing and tearing. To avoid those appearances we have developed the Doll Smooth-startup-up devices for equipment of new systems ex works and after-market equipment of existing Doll-systems.
