Commercial Kitchen Extraction
Commercial kitchen extraction is an essential part of every catering establishment. The kitchen extraction system ensures a healthy and safe environment for members of staff and customers alike by addressing the by-products of cooking processes such as heat, grease, steam, smoke and odours along with the harmful by-products of combustion produced by gas and solid fuel catering equipment appliances within the kitchen.
At Target we have measures in place to quality assure each individual commercial kitchen canopy installation. As the basis for each site specific extraction system design, Target's design engineers use the latest BESA (Building Engineering Services Association) specification for kitchen ventilation systems, DW/172 second edition 2018, to ensure every kitchen ventilation system designed and supplied complies with the very latest commercial regulations and provides adequate ventilation necessary for the needs of the commercial kitchen.
COMMERCIAL KITCHEN EXTRACTION DESIGN
A commercial kitchen extraction design can comprise of different configurations depending on site specific constructional details, building and commercial kitchen layouts, as well as, type of catering equipment appliance and choice of fuels i.e. gas, electric, charcoal or solid fuel within the commercial kitchen. A correctly designed and specified commercial kitchen ventilation system will ensure a healthy and comfortable working environment for your kitchen brigade, addressing any potential issues of air quality, harmful by-products of combustion, noise, odour and temperature control. It will also address any conditions set by local authorities to protect the surrounding areas and residents.
Target's commercial kitchen extraction design services include layouts, positions, routes and specifications of varying commercial kitchen ventilation system components including;
Extraction canopy
Extractor canopy filters
Extraction canopy lighting
Extractor ducting
Extractor fans and fan boxes
Discharge cowls and louvres
Noise suppression systems
Carbon filtration systems
Speed controllers and fan power monitoring systems
Gas safety interlock systems
Co2 (Carbon Dioxide) monitoring
Replacement air systems
Odour control systems
In order to select the correct commercial kitchen canopy installation to meet your requirements and comply with commercial kitchen extraction regulations, you will need a detailed commercial kitchen ventilation design and specification to suit your kitchen operation.
At Target, following an initial site survey to assess your requirements, we can provide a report and offer professional advice based on our findings, prepare a commercial kitchen extraction system design and specification and if required submit plans and specification details to local authorities for required planning permissions and discharge of planning conditions.

Planning Conditions Relating to Commercial Kitchen Extraction
Being granted planning permission for ‘Change of Use’ to either A3 restaurant or A5 hot food takeaway will in many cases be subject to conditions put in place by Local Planning Authorities. Prior to properties being brought into said uses, properties are typically required to submit and have approved by Local Planning Authorities full details of any measures (i.e. any commercial kitchen eqtraction systems) to be installed to prevent and control noise and odour emissions generated from the proposed commercial kitchen.
At Target we carry out site surveys and prepare commercial kitchen extraction design details and specifications required for the discharge of these planning conditions. Target design consultants prepare commercial kitchen extraction systems to suit proposed kitchen layouts based on the very latest BESA specification for kitchen ventilation systems DW/172 second edition 2018. We also offer a full ‘Acting Agent’ service for the submittal of ‘Change of Use’ planning application, where we can complete the full planning application process on your behalf, and are proud to hold a 100% success rate for planning applications being approved and conditions being discharged.
COMMERCIAL KITCHEN EXTRACTION INSTALLERS
Commercial kitchen canopy installation can be simple or complicated depending on the many variables that all need to come together to ensure the complete system works effectively and efficiently. Issues tend to arise when a complete extraction system has not been correctly designed and specified and the extraction canopies are supplied and installed with ductwork, fans and filters that have not been correctly matched.
Target design engineers ensure all components including canopy hood, ductwork, fans and filters are matched and the installation team takes care of everything including install, final commissioning, testing and certification. This includes removal of protective plastic films ready for final deep clean and handover.
Designed, manufactured and installed to suit individual requirements Target's commercial kitchen exhaust hoods are available as an individual unit or as part of a complete ventilation system.
All Target canopy exhaust hoods are manufactured in accordance to BESA DW/172 second edition 2018 specification for commercial kitchen ventilation systems.
Extraction Canopy - Gas Equipment
A commercial kitchen extraction canopy is required to remove odour and heat and also the harmful by products of combustion such as carbon monoxide gasses which are produced from the combustion process when cooking using gas appliances.
Extraction canopies for gas appliances should over-sail catering equipment by a minimum of 300mm, they will also require an external high level exhaust point in order to meet environmental health commercial kitchen canopy regulations and also a gas interlocking system to comply with BS 6173:2020 regulations.

Extraction Canopy - Electric Equipment
When no gas connection is available or commercial kitchen extraction installation costs need to be kept to a minimum, you may consider an all electric commercial kitchen incorporating powerful commercial induction cooking technology.
Induction cooking does not give off any harmful byproducts. It also reduces the amount of excess heat produced within the kitchen compared to when cooking using gas appliances. As a result of this reduced heat the commercial kitchen canopy is able to run more efficiently using lower speed controller settings. Using an all electric cookline also removes the requirement for a gas safety interlock system to be installed.

Commercial Kitchen Exhaust Hood Requirements
Constructed from brushed, commercial grade 304 stainless steel, each extract canopy is designed to overhang cooking equipment on all sides. The underside of the canopy should be positioned about 2m from the floor to enable it to function correctly removing contaminated air from catering equipment positioned below.
The components of the extraction canopy may include:
Filters - each canopy will include appropriate filters to enable adequate extraction and eliminate the buildup of grease and other dust particles in the air inlets ensuring that the extraction canopy works efficiently.
Fans and Speed Controller - fans for moving fumes from the hood to the ducts, these are ERP compliant, suitable for low voltage inverter speed control.
Drip Channel and Drawer - an essential part of the Target canopy is the drip channel which collects water vapour produced when hot air hits the cold surface of the hood. Without the drip channel condensed air will collect and drip down the back and sides of the exhaust canopy and may contaminate food being prepared beneath. The drip channel drawer allows for easy removal of the collected mositure.
Canopy Lights - the Target manufactured canopies comprise of bulkhead UL approved fittings with LED energy saving lamps fitted or recessed LED fittings. All our lights are heat resistant with shatter-proof lenses and easy clean surfaces.
WALL MOUNTED EXTRACTION CANOPY
The wall mounted extraction canopy is suitable for use with equipment positioned in a cookline backing onto a wall.
CENTRAL ISLAND EXTRACTION CANOPY
An island extraction canopy covers equipment which is centrally fixed in an island configuration. The island hood can be single or double sided as required.
CONDENSATE HOOD
The condensate hood is designed to capture, condense and remove steam from steam generating appliances such as dishwashers and combination ovens.
