Some of the technology and techniques
employed by Far East Kitchen solutions to deliver top quality ventilation
and extraction systems
Camouflaged ducting At a restaurant in Mansfield, Notts. Sometimes, the visual impact of a ventilation system must be reduced in order to make it acceptable to planning departments.
Although ducting can sometimes be camouflaged, on other occasions it may be necessary to install the ducting inside the building as much as possible; Far East Kitchen Solutions have the expertise needed to do this.
Silencers and anti-vibration mountings
Noise considerations are crucial, with most councils setting limits on
noise. A combination of careful placement of fans and exhausts, selection of
quiet fans, strategically positioned silencers and anti-vibration mountings
can be used to reduce the noise footprint both internally and externally.
The system shown on the left has two silencers, either side of the fan (these
are the wider cylinders) which are attached with a flexible connection to
prevent the transmission of vibration and oscillations. The anti-vibration
mounts are part of the wall brackets.
Activated carbon filter system
In a HVHD extraction system, grease is filtered out and odours are diluted with large quantities of fresh air, before being exhausted vertically at speed.
In some circumstances, additional odour control measures are necessary to
further reduce external odours.
Activated carbon is the industry standard for eliminating toxic fumes or
offensive odours. Carbon filters are designed to remove fumes and odour;
hence they are unable to handle fine particulates and dust. If left
unprotected, the life of the carbon is severely reduced and so they are
protected by pleated and bag filters within the system enclosure.
Electrostatic precipitator
An electrostatic precipitator unit (ESP) passes the air in to a strong
electrical field, known as the ionising section and this electrically
charges particles in the air.
It then passes into a collector section, made up of a series of plates. Each
alternate plate is charged with the same polarity as the particles, which
repels them, whilst the interleaving plates are earthed, which attracts the
particles and allows them to be collected.
The air exhausted from the rear of the unit is then almost entirely free of
contaminants, ideal for separating sub-micron smoke and grease odour laden
particulates from the air stream.
Odour neutraliser
An odour neutraliser saturates air with a special neutralising liquid, which then receives a very high negative electrical charge and is introduced into the exhaust duct where it combines with the positively charged odour, thereby eliminating unpleasant odour emissions.
Gas Interlocking System
This system is now mandatory in many installations and prevents gas
appliances being operated without adequate air flow in the kitchen.
