Furthermore, when the Trinc-1 (triac controller integrated in fan motor) was introduced, it was pointed out that the Trinc-1 is protected against harsh environmental circumstances, f.i. humidity and mechanical stress. In addition, due to the applied production method of low pressure injection, the Trinc-1 is highly reliable. The economic lifetime is guaranteed as such, that Vostermans Ventilation provides this product with a 3-year warranty as well. The 3-year warranty period is also applicable for the standard Multifan, EMI and Mf-Flex motors. The decision for the extended warranty period is supported by positive experiences from applications worldwide and feed back from the satisfied customers.
