Commercial Kitchen Extraction from KCM Catering Equipment

Commercial Kitchen Extraction from KCM Catering Equipment
Ventilation within a commercial kitchen environment is extremely important, not just from a comfort perspective, but also for health and safety.

The purpose of a kitchen extraction system has always been to remove heat and grease generated from the cooking equipment beneath it, however it also serves a much wider role. The use of gas cooking equipment creates carbon monoxide gasses from the combustion process, warewashing equipment and boiling generates steam all of which need to be removed from the working environment.
In order to provide a safe and comfortable working environment, commercial kitchen extract systems need to address a number of key areas. For the comfort of those working in the kitchen, ventilation needs to be provided to ensure sufficient clean, cool air, furthermore the supply of air must be sufficient for complete combustion of gas burning equipment. The gasses then generated by the combustion process needs to be effectively removed from the working environment and expelled to a safe exterior location. Commercial Kitchen Extraction Systems 3
The removal of these gasses should take place as close to the generating source as possible. Any system should be effectively kept clean from grease and fat residues to prevent any possible fire hazard or reduce the effectiveness of the system.

Air that is extracted from the kitchen environment needs to be replaced, as a general rule approximately 85% of the total air needed should be provided by mechanical ventilation with the remainder drawn from surrounding areas. In some kitchens it may be acceptable to provide the replacement air by means of ventilation grilles in walls, doors or windows, if this method is used then some form of fly screen should be used to prevent pest problems.

Kitchen Extract System Design

Commercial kitchen ventilation systems can be designed for either back or front of house, tailored to individual operational and design requirements. They can be either of a wall or island type with various options for filtration systems.

Most commercial ventilation canopies will use Baffle grease filters, as air is drawn through them it is forced to change direction and speed, this causes the grease to separate and run off into collection troughs. Generally cleaning of the filters can take place in a commercial dishwasher.

Other filtration systems are available, some of which are also able to remove odour as well as grease particles. We would tailor any system to your requirements to meet not only your operational but also budget needs.

Gas Supply Regulations (BS 6173)

All new and some existing installations where modifications or new equipment is being installed must have a gas interlocking system to comply with BS6173:2009
Gas Supply Regulations (BS6173) 2The installation of an interlock system will prevent the gas from being turned on until the ventilation system is fully operational. An interlock system uses an air pressure sensor or electrical current monitor to detect when the canopy is operational and working with sufficient air flow to comply with the regulations, once these conditions are met the system will allow a normally closed gas solenoid valve on the incoming gas supply to open.
While the air flow continues to meet the requirements gas equipment can be used normally, if the airflow falls below the required level or the ventilation is switched off the gas flow will be automatically switched off.

All systems that we supply and install for commercial kitchens using gas fully comply with BS6173:2009 with all gas components and catering equipment installed by commercially registered Gas Safe Register (previously Corgi) installation engineer

Where an existing ventilation system is in place the installation of an interlock system would be required by the replacement or retro installation of a Class 2 gas fired appliance, most but not all commercial gas fired prime cooking equipment falls into this category.

If you are looking just for a Gas Interlock System to ensure that you comply with BS6173 then we also sell the individual components (click here).

Stainless Steel Wall Cladding

Stainless steel wall cladding is ideal for areas which are directly subject to high temperatures, for example behind cooking ranges and under extract canopies. Also very easy to clean and fully EHO compliant, stainless steel sheeting can be tailored to suit most cooking areas.

We can supply and install stainless steel cladding to go beneath kitchen extraction canopies, or anywhere else where it may be required.
