WHY CHEETAH CONTROL? DEMAND BASED VENTILATION CONTROL FOR COMMERCIAL KITCHENS Cheetah Energy Control Cheetah - is an energy saving control system for commercial kitchens. It controls the extract and air supply fans to ensure that at all times they run at the lowest speed possible to minimise energy use whilst maintaining comfortable and safe conditions. To achieve this, the Cheetah system monitors the hood with laser optic sensors which detect smoke and steam. At the same time, it also measures the temperature within the extract ductwork. The data is then used to control the extract and supply...
