Frequently Asked Questions
How Does Intelli-Hood work?
Intelli-Hood utilises dual sensing to monitor cooking activity and implements VFDs (variable frequency drives) to modulate the exhaust fan speeds. This demand control ventilation system reduces energy consumption by operating fans only as needed, enhancing efficiency and comfort in commercial kitchens.
When can Intelli-Hood be installed?
Intelli-Hood can be planned and installed at various stages:
During new construction design phases to maximise long-term energy savings.
During kitchen remodels when upgrades are being made to the commercial kitchen’s ventilation system.
Years after initial installation as a retrofit to existing hoods to improve efficiency and reduce operational costs.
How long does installation take?
installationThe installation duration for Intelli-Hood varies based on the complexity and size of your kitchen ventilation system, as well as the number of optics required. Typically, instillations are completed within a few days, minimising disruption to your operations.

Retrofit
What does a DCKV retrofit installation involve?
A DCKV retrofit upgrades an existing commercial kitchen ventilation system with intelligent controls. Sensors and variable speed drives are added to the existing system so fan speeds adjust automatically based on real cooking activity.
The existing canopies are retained and do not need to be replaced.
What happens during the initial site survey?
The site survey reviews how the kitchen currently operates and checks that the existing mechanical systems are suitable.
This includes inspecting extractor fans, make-up air units, canopies, ductwork, and current maintenance practices. The kitchen footprint, electrical infrastructure, and existing safety interlocks are also recorded, along with local regulatory and site-specific requirements.
How long does a DCKV retrofit installation take?
Installation time depends on the size and complexity of the kitchen.
Smaller kitchens may take one to two days, while larger kitchens with multiple canopies may take longer. Installations can often be phased to reduce disruption.
Can installation be carried out while the kitchen is operating?
Yes. Because this is a retrofit, installation can be planned around normal operations.
Work is often carried out overnight or during quieter periods. This is common in hotels, leisure venues, and sites with extended operating hours.
How much disruption should we expect?
Disruption is usually minimal.
Most physical installation work is completed before the system takes control of the kitchen ventilation.
Final connections and commissioning are completed at the end of the works, once all components are in place.
What equipment is added during a retrofit?
A typical DCKV retrofit includes:
Temperature sensors installed within the canopy
Optical sensors to detect smoke and vapour
A controller or touchpad
Variable speed drives on exhaust and make-up air fans
These components integrate with the existing ventilation system and, where required, the building management system.
What happens after installation?
Once installed, the system is commissioned and tested to confirm correct operation.
Fan speeds are verified to respond to real cooking activity, with typical average speeds reducing to between 40% - 70% rather than running constantly at full speed.
What are the benefits once the system is live?
A properly installed DCKV retrofit can reduce ventilation energy use by up to 90%.
It also reduces wear on mechanical equipment and provides better control of the kitchen environment.
