Ventilation Systems

Why is Ventilation important?

Cooking produces significant quantities of fumes and vapours as well as high temperatures. Ventilation systems are necessary to remove and discharge these to a safe external location.

The ventilation system should also provide general ventilation throughout the area. It is particularly important to provide an adequate supply of replacement air, as incorrect flueing arrangements can lead to incomplete combustion and the accumulation of combustion products such as carbon monoxide.

Air Movement

Comfort

Air movement is crucial factor in thermal comfort. If air is stagnant in artificially heated areas it can contribute to musty odour problems and feelings of stuffiness. Whereas small movements of cold air can be considered draughty and unpleasant.

But in a warm or humid environment air movement can be preferable as it helps with heat loss without any change in the air temperature.

Odours

In a commercial kitchen environment with high temperatures and cooking odours, an intermittent or constant air movement can help with the comfort of staff.

Fumes

Any dangerous fumes and vapours must also be removed from the cooking area and immediately discharged. In modern restaurant design it is common for the kitchen to be open plan with the seating area so it is crucial that air movement keeps heat, noise and cooking odours within the cooking area and away from customers. The diners' thermal comfort adds to the overall enjoyment of the dining experience.

Fume and Vapour Extraction

Vapour

Heat / Fume Extraction and Vapour Extraction in a commercial kitchen need to combined into one single unit. This presents a challenge for the system as it needs to separate the heat and fumes from the water vapour.

But in a warm or humid environment air movement can be preferable as it helps with heat loss without any change in the air temperature.

Filter

Centrifugal force is used to transfer the water vapours to a baffle filter, the water is then channelled and removed every few days by removing a grease cover.

Discharge

Heat / Fume extraction is then performed and the air is discharged through the ductwork either externally or through a heat recovery / heat exchanger system to recycle the heat to other parts of the building.

Kitchen Canopy

Extraction

We always recommend a kitchen canopy is positioned directly above the cooking equipment to provide immediate extraction of all fumes and vapours protecting kitchen staff.

Our stainless steel extraction kitchen canopies can be manufactured to your exact specification, in line with HVCA DW/172 specification..

Greases

Extraction canopies are used to remove all greases and particles in the air. They are then taken through the ductwork and discharged in a safe location.

Fresh

Condense canopies are mainly installed over equipment that produces steam, such as combination ovens, Bain Marie's, pass through dishwashers and sterilising sinks. The basic principle is the same as an extraction canopy but with baffle plates and a drain off point for the condensation.

The kitchen canopy will also provide replacement air flow to bring fresh air into the kitchen.
