SMEC Power & Technology are pleased to announce trials of the Ventilation on Demand System utilising our Smart VOD System and Magnetek GP1000 M-Force 1000V VVVF Drives has continued to provide realised savings of 52.9% Aux Fan energy costs.


Released energy savings taken over 6-month periods – show with only six VVVF Drives with Smart-VOD operating 110kW fans have offered savings equivalent to 400,000 litres of diesel, as well as approx. 1070 tons of CO2 emissions avoided.


SMEC will continue working with the team at Westgold to continue providing increased savings throughout Westgolds’ operations utilising the Smart VOD systems’ autonomous control and the Magnetek GP-1000 M-Force 1000V VVVF Drive

Key Features to achieving these savings for Westgold

The Smart VOD system autonomously adjusts Aux Fans speeds to maintain the required ventilation, utilising the VVVF Drives to manage a range of energy consumption between 3% through to 100% across fan speeds.

Vent bag inflation is achieved with a minimum energy consumption of 3%.

Reducing the fan by only 20% to a fan speed of 80% of the rated RPM has seen as much as a 50% reduction in power consumption.
