Welcome

• 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

• 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

• 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

• 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?

Our customers

• 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.

Grease & Odour in commercial kitchens

It is recommended to install the appropriate abatement equipment to ensure

that the extraction air conforms to local Environmental Health standards.

Electrostatic Precipitators (ESP) Moderate Moderate

Panel, Bag and HEPA filters   High High

Solutions

• 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

A modular approach...

• 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

• 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

• 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

• 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

Independent testing

The Plasma Clean Xtract has been tested to European Standard

EN13725:2003 by independent odour concentration measurements

ACHIEVED: Up to 90% odour removal

USPs

• Compact and lightweight unit • Low power • Two year parts warranty• Long life UV-C lamps and ballasts • Simple on-site maintenance• Easy retro fit product

• Flagship pub in residential area• Significant odour issues• Environmental Health stipulated odour control measures• EHO Approval obtained for the Plasma Clean Xtract 2100

Case Study – Joshua Bradley

• Low power system – only 160W per unit• Stainless steel and glass construction – fully recyclable • No harmful NOx emissions from production of ozone• Sits outside of the ductwork so adds no back pressure

- Easy retrofit with no significant ductwork modifications- No additional power required to push air through duct- No fan upgrade required

• No noise• Low maintenance• No landfill impact as seen with activated carbon• Cost effective odour control performance• Low carbon footprint

Environmental advantage

• Electrostatic Precipitators (ESPs) work by

ionizing and trapping grease and smoke

particles onto collector plates.

• They have high particulate removal

efficiency combined with low static pressurePCL 4420

PCL 6630

Electrostatix

• Greatest efficiency with highest volume flow rate capacity - 95% at 4420 and 6630m3/hr

• Two year parts only warranty• Robust power supply for longer life• Spiked ioniser blades - more robust than wire ionisers for longer life• Low pressure drop• Combines with Techniclean UVC for high efficiency grease, smoke

and odour control

USPs

Efficiency

• High energy UV-C lamps are used to break

down odours and traces of grease in the extract

air by the mechanism of photolysis and

ozonolysis – combining high intensity UV-C light

with ozone technology.

UV-C Filtration

• Slim-line and lightweight ducted unit• Low power• Long life UVC lamps and ballasts• High flow capacity• Two year parts warranty• Low pressure drop• Combines with ESP for high efficiency grease, smoke and odour
