Britannia Ventilation has introduced the Refresh recirculating air system, a self-contained kitchen ventilation system that is said to need no direct duct connection to atmosphere.
Therefore, this should make it suitable for kitchens sited in less conventional places and restaurants that have run out of space beneath existing hoods.
By using recirculating hoods, the Refresh system allows caterers to take full advantage of existing spaces with minimal cost implications when compared to the retrofitting of permanent exhaust hood fans and ductwork.
A Refresh unit can also be used to set up a cooking station in previously unattainable areas of a building.
Suitable for any kitchen using light to medium electrically powered equipment such as bratt pans, fryers, griddles and pasta cookers for example, a Refresh unit is claimed to be simple to install.
Britannia believes that energy saving fan motors and efficient fume saving features make it ecological. The filtration system takes the air through multiple stages to remove grease, particulate, smoke and odour before re-introducing it to the kitchen space.
The Refresh stand-alone units, all constructed in 304 grade stainless steel, come in a number of sizes, ranging from the Refresh Mini, suitable for a single piece of equipment of up to 500mm wide, up to the Maxi for multiple pieces of equipment up to 1,500mm wide. The Refresh Ultima range includes seven models increasing in size to cater for multiple runs up to 3,600mm wide.
Refresh units need no direct duct connection to atmosphere. However, Britannia suggests a small amount of background extract ventilation which is normally provided in most kitchens. The frequency of filter changes will depend on the intensity and type of cooking.
