Dutch ventilation specialist Vostermans Ventilation has developed a variable speed control for single-phase fans, which ensures they operate at the correct speed in all conditions.
The Trinc-1 has a triac controller incorporated within the fan motor itself, which constantly detects the speed of the fan motor and corrects any speed variations. The result is that producers can be assured that the fan remains at the correct revolutions per minute regardless of external wind or pressure influences, said Vostermans Ventilation.
A key feature of the Trinc-1 is that the controller is encapsulated in the motor housing through a low pressure injection technique, as used in the automotive industry. The company said this protects the controller against harsh conditions, humidity and mechanical stress, thus resulting in its high reliability.
