Optimum energy usage regulated by assessed cooking activities (steam, smoke and exhaust air temperature) enables significant savings in fan energy usage, maintenance and fan life – as well as conditioned supply air during idle, low or non-cooking periods.

Advanced energy controls, operated by Variable Frequency Drives giving variable control to exhaust fans, make operating decisions on the precise levels of energy required for comfortable and safe operating efficiency.

With conventional systems, exhaust and make-up air fans operate at 100 % or 0%.  Automatic exhaust fan control systems will assess the varied energy requirements throughout the working period adjusting fan speeds automatically to optimum energy usage based on continuous sensor assessment of actual cooking activity at each hood workstation.
