3. • Kitchen Ventilation
– Restaurants, shopping malls, airports, fast food
• Ambient Air
– Washroom, hotel rooms, waste storage areas
• Waste Processing and Storage
– Waste storage and composting
• Food Transportation and Storage
– Soft fruit and vegetables, meat and fish
• Food Manufacturing
– Preparation and processing
Applications

4. • There is an increasing demand by Local Government to reduce
odour, grease and smoke emissions associated with the activities
of commercial kitchens.
• Emissions control usually arises during the planning phase, or
when the local authority has received complaints from the general
public.
• Failure to comply with planning conditions can lead to delays in the
planning process, or existing businesses could face closure.
Local Government

5. • Legislative guidelines in the UK: DEFRA 2005 / 2010
• DW/172 Guidelines
•TR/19 - Reduce grease build-up to prevent fire risk
• Odour control for low level discharge
• EHO approval and enforcement
• Penalties for non-compliance including closure
• Duty to Neighbours and to the environment
Guidelines

6. • From an environmental perspective, offensive odour
emissions affect the quality of life of individuals,
impacting neighbouring businesses or affect the
customer experience.
• Economically, by reducing the amount of grease and
smoke which enters the ventilation ductwork, the duct
cleaning frequency is reduced, heat recovery is possible
and fan maintenance is reduced.
• From a safety perspective, by preventing grease from
entering the ductwork there is a reduced fire risk.
Why treat odours?

7. Our customers

8. • The proportion of odour, grease and smoke depends on the type of cooking.
• Odours are caused by volatile molecules found in the ‘gas phase’
• Grease and smoke are tiny particles and so are in the ‘particulate phase’
• It is recommended to install the appropriate abatement equipment to ensure
that the extraction air conforms to local Environmental Health standards.

11. • Treat in order of Grease => Smoke => Gaseous odour
• Interlock equipment with air flow either through fan control or PDS
• Ensure that fan has Pa capacity to handle additional pressure drop
• Check linear velocity through main duct run (6-8m/s) to ensure that
there is sufficient dwell time in equipment
• Use activated carbon if there is insufficient contact time for ozone (2
seconds), or if extracting at low level
Key design criteria

12. A modular approach...

13. • Latest non-thermal plasma and UV-C technology
• Two year limited parts only warranty
• Low capital and running costs
• Simple installation and maintenance
• Compact, lightweight and robust
• Great after sales
INNOVATIVE, CUTTING-EDGE SOLUTIONS FOR
GREASE, ODOUR AND SMOKE CONTROL
Product USPs

14. • Efficiency - up to 95% of grease particles
• Pressure drop – 200Pa
• Linear velocity - 4.2m/s
• Volume flow rate – 0.24 and 0.34m3
/s per filter
• Weight – 3kg
• Retrofit using an adaptor plate
• H x D x W mm - 150x475x161 or 150x375x161
• ROI – 12 - 18 months
Coil Filters

15. • Ozone is injected directly into the canopy or
ductwork as close to the source of odour as
possible
• A minimum of 2 seconds dwell time is
required to allow the ozone to react with
odours
• Ozone also reacts with low levels of grease
and smoke
• Treats up to 2m3
/s air flow
Ozone Injection

16. • The Plasma Clean Xtract generates
ozone, a well known cleaning agent to
combat odour
• Ozone is created from ambient air and
injected into extraction system
• Customers also notice that grease and
smoke is reduced in the air stream and
on ductwork surfaces
• Odour and ozone removed
How it works

17. Independent testing
The Plasma Clean Xtract has been tested to European Standard
EN13725:2003 by independent odour concentration measurements
