Kitchen Ventilation Canopies
Supply Air Canopies – Britannia Model BKV12
The canopy has insulated supply air plenums incorporate Supply air
diffuser panels to deliver make up air at low velocity back into the
kitchen. This method of providing make up air removes the need for
extensive ductwork runs and additional supply air grilles in the kitchen
ceiling. The make-up air is normally around 80-85% of the extract volume
to ensure a negative pressure is achieved in the kitchen. The supply air
is generally conditioned prior to introduction through the canopy.
Induction Canopies – Britannia Model BKV13
The canopy has insulated supply air plenums mounted along the two
long sides of the canopy. These plenums incorporate stainless steel
induction slots to delivery air internally at high velocity. The
induction principle relies on a high velocity jet of air directed
towards the grease filter panels. This untreated air (approx. 20% of
extract volume) induces the extract fumes towards the filters and lowers
the temperature making the filters more efficient. Induction does not
however provide make up air to the kitchen.
Combination Supply Canopies – Britannia Model BKV1234
The combination supply canopy combines the benefits of induction and
supply air with the added benefit of personal supply air nozzles to
provide localised air movement towards operatives.
This can combat the effects of radiant heat.
Please note that any method of air movement can be combined to create
the ideal solution for your particular ventilation problem.
Please consult Britannia for free advice and assistance.
Silverline Kitchen Ventilated Ceiling System
The Silverline Ventilated Ceiling System protects the cooking
equipment by a dedicated extract chamber, which forms a positive fire
barrier with integral grease collection and drainage system. The
surrounding ceiling area is made up of insulated, stainless steel
ceiling tiles.
The system utilises the void above the ceiling as a pressurised supply
air plenum. This ensures that only clean air is passed through the
ceiling void, ensuring structure and services, which pass through the
void, remain uncontaminated.
As the grease is collected and contained within the grease filter
housings, the kitchen equipment and the extract ductwork connections can
be protected using a proprietary fire suppression system.
Heydal Ventilated Ceiling System
Heydal is a fully integrated ventilated ceiling system from Britannia
that is designed for ventilating large commercial kitchens.
The ceiling is made up of a supporting framework which is divided into
500mm square modules, made up of grease filters, supply diffusers,
lights and blanking panels.
Heydal has many advantages, firstly it has greater flexibility allowing
the cooking equipment layout to be modified in the future, also the
ceiling offers a clean line of sight across the kitchen which improves
aesthetics, ideal if the kitchen is on sight to the diners.
Only the exhaust modules and grease collection troughs require regular
cleaning, all modules are easily removed without tools and are suitable
for cleaning in a commercial dishwasher. Britannia also supply
maintenance contracts to ensure the ceiling is always in excellent
condition.
