Kitchen grease extract ductwork cleaning

What is a kitchen grease extract ductwork system ?

The B&ES / HVCA in TR/19 Guidance to good practice define kitchen extract ventilation as "the extract systems intended to collect and remove contaminants, heat and moisture from cooking appliances". A grease extract duct system is made up of the following components:-

Canopy hood - types are box / ridge.
Filters - mesh, baffle or cartridge type are most common. 
Extract plenum - void area immediately behind the filters. 
Grease extract ductwork - duct controls the flow of air. 
Fan and fan housing. 
Access panels - method of obtaining entry to the ductwork interior. 
Exhaust grill.

Purpose of a kitchen grease extract ductwork system

Remove heat, smells / odours and steam from the kitchen. 
Removes greasy vapours from the kitchen which is an ignition source. 
Produces a safe working environment.

During the cooking process flammable vapours are given off from cooking oils at temperatures between 200 to 300'C. "Spontaneous ignition occurs at 310-360'C" (Source : RC44 - Recommendations for fire risk assessment of catering extract ventilation BSRIA).

Grease extract ductwork cleaning helps reduce the flammable materials that build up within the system.

It should be noted that insurance companies now stipulate as part of a building's insurance terms the requirement for grease extract ductwork to be cleaned on a stated frequency (normally once or twice per annum). They remain the driving force in ensuring that cleaning is carried out.

"Bends or dips which might collect residues are to be avoided and the whole of the ducting should be accessible for cleaning. At each change in direction of the duct an opening with grease-tight cover should be provided for the purpose of inspection and cleaning. A residue traps and fire dampers should be installed at the base of any vertical riser

Frequent cleaning of filters or other grease removal devices is particularly important. Cleaning intervals depend on the type of equipment and the extent of its use but should not exceed seven days. … Cleaning should take place at intervals not exceeding 12 months by a specialist contractor. This may require cutting of openings in the ductwork if none have been provided."

The Commercial Duct Cleaning service

Our kitchen ductwork duct cleaning service looks at the grease extract duct system from the point of entry via the canopy, filters through the ductwork run to air. Before and after duct cleaning photographs are taken of the system ductwork. As one of the leading experts in grease extract ductwork cleaning this service is designed to significantly reduce the grease and carbonisation associated with extract ducting from the point of entry to atmosphere. Each kitchen ductwork cleaning treatment will reduce the hazards of flash fire and enhance the extract flow of air.

We provide a full schematic drawing of the kitchen grease extract ductwork system. This is produced with a comprehensive written survey and risk assessment, FREE of CHARGE, together with our quotation. All grease extract duct cleaning carried out follows the latest guidance to good practice TR-19 section 7 by the B&ES / HVCA.

Canopy is degreased internally and externally including the filters, filter housings, drip trays, canopy lips, light fittings. The duct cleaning will start with degreasing and inaccessible areas will have access panels fitted to facilitate cleaning. Extract fans will be removed if possible for cleaning and decarbonizing. Take photographs from an initial survey but also as evidence of the Project, both pre and post cleaning. All works are validated with digital photography being taken as a visual of the works.

How often should you clean?

Other risk factors such as vulnerability of the system to ignition and of the building and its occupant/users to system fire, hygiene, vermin and mechanical hazards. Typical duct or ventilation cleaning intervals are shown in the table below:

Heavy use               (12 -16 Hours per day) once every     3 monthly

Moderate use         (  6-12  Hours per day)  once every     6 monthly

Light use                 (   2-6    Hours per day) once every    12 monthly

Free Inspection Survey

We can explore the ductwork system with a CCTV crawling camera and produce a visual representation and short written report of the recommendation and observations.
