Intelligent Demand Controlled Kitchen Ventilation
Cheetah is an intelligent demand controlled kitchen ventilation (DCKV) system that continuously matches ventilation performance to actual cooking demand – reducing energy use, operating costs and noise without compromising safety, compliance or kitchen performance.

Traditional kitchen ventilation is designed for the worst case - and runs that way all day
Commercial kitchen ventilation and extract systems are typically designed for maximum cooking loads. But in reality, kitchens operate with highly variable demand throughout the day. Between services, during prep, and in quieter windows, traditional systems often:
Run at full speed unnecessarily
Consume excessive energy
Rely on manual adjustment
Operate on static BMS timers
How Does Cheetah's Demand Controlled Kitchen Ventilation (DCKV) Work?
Cheetah's DCKV system uses intelligent sensors and automatic fan control to continuously adapt commercial kitchen ventilation to actual cooking demand.
Intelligent Sensors
Cheetah monitors cooking activity and environmental conditions within the kitchen, building a continuous picture of real demand.
Dynamic Fan Modulation
Based on sensor data, fan speeds are continuously adjusted. Over-ventilation during low-demand periods is eliminated.
Full Capacity on Demand
Full extraction is always available the moment it's required. Safety, compliance, and performance are never compromised.
Benefits of Demand Controlled Kitchen Ventilation
Significant energy reduction
Up to 80% fan energy reduction during quieter periods. Typical average savings of 50–60% across a full day's operation - often thousands of pounds annually.
Reduced noise
Lower fan speeds for extended periods reduce mechanical and aerodynamic noise - improving working conditions and comfort in adjacent areas.
No manual control needed
Once installed, Cheetah optimises ventilation automatically. Consistent performance without operational burden on kitchen teams.
Fully compliant
Supports UK Building Regulations Part F and Part L. Fail-safe operation - reverts to full speed in the event of a fault. Safety always maintained.
Reduce commercial kitchen ventilation energy consumption
Commercial kitchen ventilation can account for a significant amount of energy use, particularly when extract and supply fans continue operating at full speed regardless of cooking demand.
Cheetah reduces unnecessary fan operation by automatically matching ventilation levels to what's happening in the kitchen. During quieter periods, fan speeds reduce; as cooking demand increases, ventilation responds automatically.
Every site is different, which is why we provide site-specific savings calculations, specification packs and direct engineering support to make Cheetah straightforward to specify, install and operate.

Frequently Asked Questions
Demand controlled kitchen ventilation (DCKV) is a system that automatically adjusts kitchen ventilation according to actual cooking demand. Rather than extract and supply fans operating at full speed throughout the day, DCKV uses real-time information from the kitchen to increase or reduce ventilation as required. Cheetah is Quintex's intelligent DCKV system, designed specifically for commercial kitchens.
Yes. Cheetah is designed for both retrofit and new build. We assess your existing extract configuration and tailor the system to integrate seamlessly — whether you operate a single canopy or multiple extraction zones. In most cases it works with your existing fans, controls, and ductwork.
Savings depend on the kitchen, operating hours and existing ventilation setup. Cheetah installations typically achieve average ventilation energy reductions of 50–60% across a full day's operation, with fan energy reductions of up to 80% during low-demand periods. We provide site-specific ROI calculations based on the actual operation.
A DCKV system monitors activity within the kitchen and adjusts ventilation fan speeds accordingly. Cheetah uses intelligent sensors to identify changes in cooking demand, automatically reducing fan speeds during quieter periods and increasing ventilation when required. Full extraction capacity is still available whenever it is needed.
Most Cheetah installations are completed within one to two days. Installation is planned to minimise disruption, and scheduling is coordinated to suit your service patterns wherever possible.
Cheetah is a fail-safe system. If a sensor or control component fails, the system automatically reverts to full-speed fan operation - ensuring kitchen safety, ventilation performance, and regulatory compliance are never compromised.
Yes. Cheetah supports compliance with UK Building Regulations Part F and Part L. Variable speed drives are mandatory for larger extract fans — Cheetah provides safe, efficient fan speed control, improving part-load performance while maintaining full ventilation capacity when required.
Yes. Cheetah includes data logging and monitoring capability providing visibility of fan speeds, temperatures, airflow behaviour, and energy consumption — supporting performance verification, proactive maintenance, and long-term optimisation.
