Quintex has worked with a variety of different quick service restaurants, including KFC, Nando’s, Wagamama’s, Ikea, Deliveroo and more. In this case study, we will explore the technical aspects of their ventilation systems and highlight the energy savings achieved through our Cheetah solution.
Cheetah is a demand control kitchen ventilation system that uses a series of network sensors installed into the kitchen ductwork and canopy that monitor the activity on the cookline. Cheetah can slow down the fan speeds to as low as 40% during low-demand periods, which uses only 6.4% of the required power.
At two sites, KFC’s two 3kW fans running at full speed, consume a total of 40,500 kWh and, at a rate of 25p per kWh, this equates to £10,000 annually for running the fans 15 hours per day. This wasn’t sustainable financially and had a big environmental impact as they are also producing 5 Tonnes of CO2 each year.
Our proven DCKV system, Cheetah, was implemented into their kitchen’s ventilation system, and as a result, the energy consumption was dropped to 16,800 kWh, saving 23,700 kWh and nearly £6,000 per year, cutting their fan energy usage by 58%.
Each year we save KFC Birmingham 2 sites;
23,875 kWh saved each year
5 Tonnes of CO2 saved each year
£6,000 Saved each year
17 months Return on investment
58% Fan energy reduction
Now let’s compare this to Nando’s. Across five sites, Nando’s was consuming 448,000kWh annually, which, at an energy rate of 25p per kWh, resulted in £112,000, just to run their kitchens fans. Their extract fans are rated at 7kW, significantly larger compared to KFC.
After installing Cheetah, we’ve reduced their fans consumption to 235,000kWh, saving them 212,000kWh each year. Nearly cutting their fans energy usage in half! Saving them £53,000 and 48 Tonnes of CO2 each year.
Since Cheetah was installed, we save Nando’s [across 5 sites];
212,170 kWh saved each year
48 Tonnes of CO2 saved each year
£53,000 Saved each year
