Electric Flying Insect Killer Technical Training Course 1. The need for insect control
1. Why do we need insect control? Food premises need an appropriate approach to insect control to... Food safety legislation The Hazard Analysis and Critical Control Points (HACCP) system is an internationally recognised preventive approach to food safety A Guide to the Food Safety of the Australia New Zealand Food Standards Code 3rd Edition, November 2016(SAFE FOOD AUSTRALIA of the Standards Chapter 3 applies to Australia only) Environmental Health Officers (EHOs)audit facilities to ensure they meet the requirements The NZ Food Act 2014 came into force on 1 March 2016. A food operator needs to meet with the requirements of the Food Act 2014 and register a Food Control Plan (FCP) with the local Council. 4
Electric Flying Insect Killers Category Overview 2. What is a flying insect killer?
Flying Insect Killers are commonly called Electric Fly Killers 2. What is an electric flykiller? Electric flykillers (EFKs) utilise ultra violet (UV) light to attract flying insects Ultra violet tubes create UV at the optimum level to match the eye sensitivity of flying insects There are two common methods of killing flying insects 1. An electrified killing grid 2. A glueboard 6
What is an electric flykiller Killing grid? There are three key components of killing grid flykillers 1. UV tubes Which attract the flying insect (also ballast & starter) 2. Transformer Which powers a killing grid, which zaps the fly dead 3. Catch tray Retains the fly carcass for hygienic disposal UV tubes Catch tray Transformer
What is an electric flykiller Killing grid To test the killing grid flykiller, insert a grid tester into the electrified grid If the killing grid arcs, causing a spark, the killing grid is live If there is no arc, there is a problem with the unit
What is an electric flykiller Glueboard? There are two key components of glueboard flykillers 1. UV tubes Which attract the flying insect 2. Glueboard Which retains the fly for inspection or disposal UV Tubes Glueboard
What is an electric flykiller? Three types of Flykiller Categories Killing Grid Glueboard 1. Killing grid 2. Glueboard 3. Decorative
Global power supply variations Different countries have varying mains supply Electrical equipment must be appropriate to run of the mains supply For example, the UK runs off 230v 50Hz If the electrical equipment is not designed to run of this mains supply it will either not work or fail Common mains supply variations we encounter are Europe and GB 230v ~ 50Hz USA Australia New Zealand 110v ~ 60Hz 230v -240v~ 50Hz 230v -240v ~50Hz
Flykiller Technical Training Course 3. Key Components of a Fly Killer
3. Key components UV tubes UV tubes produce ultra violet light, which humans can not see Most UV tubes emit light at a wavelength of 368nm (UV-A), which matches the eye sensitivity of flying insects UV tubes only work efficiently for 8,000 hours & should therefore be replaced every 12 months Starters should be changed at the same time Some tubes eg the Synergetic tubes combine UV and visible green light, which makes them more attractive to a broader range of insects Based upon a unique phosphor mix, patented technology ensures that a broader two peak wavelength is maintained (368nm & 540nm) attracting a wide range of insects including stored product moths, whilst attracting the common housefly as effectively as traditional blue UV tubes. A wide diversity of insects were shown to be more attracted to Synergetic light, including: Greenhouse whiteflies, silverleaf whiteflies, thrips, leafhoppers, Indian meal moths, Mediterranean flour moths, tropical warehouse moths, warehouse moths, plus many more!
The light spectrum UV used within flykillers is known as UV-A UV-A is invisible to the human eye due to its wavelength of 315-400nm Length if the UV light is measured in nanometres 1 Nano metre equals one billionth of a metre ( 0.000000001 m)
UV Tubes An overview Ultra violet (UV) is used within flykillers to attract flying insects Broadly speaking, the higher the amount of useful UV output from the flykiller, the larger the area that can be protected A wavelength is a measure of a repeated wave within a certain frequency The length of a wavelength is measured in nanometres, measuring one millionth of a millimetre 16
Common types of UV tubes
Irradiance testing As UV is invisible to the human eye, it is impossible for us to know whether a tube is producing UV UV tubes will continue to glow blue (or green) forever, but if they are not producing UV, they will not attract flying insects Pelsis has unique test equipment which allows them to measure a full spectral irradiance emitted from UV tubes, both when new and over time. They remain sceptical of inexpensive hand held UV measuring devices. 18
Tube diameter There are three different diameters of straight tubes used throughout the industry Described as T5, T8 and T12, typically higher wattage tubes have a thicker diameter (38mm) (25mm) (16mm)
The demise of T12 tubes However, the entire lighting industry is moving away from T12 tubes Compared to T8 and T5 tubes they are 1. Less efficient 20w tubes draw more power than 18w tubes 2. More expensive More glass / Shatterproof sleeving material 3. More fragile Bulky T12 tubes are less robust 4. Less ecologically sound They require more mercury to light US legislation already bans the sale of ballasts to power T12 tubes Philips, the worlds largest fluorescent tube manufacturer stopped producing T12 tubes in 2010 Havells Sylvania are already developing T8 replacements for their T12 tubes, in preparation for stopping production
What are shatterproof tubes? Shatterproof tubes incorporate a plastic sleeving that is designed to retain all shards of glass in the event of a breakage Many sensitive applications such as food prep. Incorporate a glass free policy which demands the use of shatterproof tubes Good quality shatterproof tubes should be translucent, both when new and after use, so a silver band provides clear indication of sleeving Sleeving can be applied to almost all designs of fluorescent tubes 21
Sleeving material The material used to sleeve UV tubes is crucial to retaining glass shard throughout the tube life, whilst remaining effective in attracting insects Poor quality sleeving material can Stop UV light from passing through the sleeving Allow shards of glass to escape in the event of a breakage Discolour over time, dimming the effects of the light Even appropriate material can be ineffective at retaining glass shards if it is applied too thinly The only appropriate sleeving material for UV tubes is Fluorinated Polymer (FEP) 22
Implications of poor quality sleeving Performance tests Pelsis commissioned an independent source to test two sets of the same specification UV tubes using different sleeving materials One set used FEP, whilst the other used RT375, an alternative material The tests were designed to quantify two key performance indicators 1. UV transmission through the sleeving 2. UV absorption by the sleeving, indicating the potential for material failure
Fluorinated Polymer (FEP) FEP is designed specifically for optical transmission, allowing up to 97% of UV passes through FEP, maintaining efficacy in attracting Insects As a result, only 3% of the UV is absorbed by the FEP, minimising the effects on the structural integrity of the material FEP maintains consistent performance in retaining glass shards throughout the full life of a UV tube High resistance to high temperatures associated with fluorescent tubes Legislative conformity Approved to existing FDA standard and draft IEC 61549 : 2003 Fragment Retention standard of 90% light emission
Key components The glueboard Glueboards silently catch flies, which die of dehydration within hours High quality glueboards should work effectively for up to 3 months To work effectively, high quality glueboards should include Pheromone impregnated glue for extra attractiveness (Z-Trichosene) UV stable glue that remains tacky for up to three months Flat board material to allow for even applications of glue Dry glue which remains on the board when touched Varnished card which doesn t dry out the glue Silicon release paper for easy removal Printed grids for simple insect analysis Evenly applied glue with consistent thickness Examples of glueboards
Gridded Glue Board counting and identifying numbers Black Front of house - no visible insects White - Gridded or plain Yellow - Gridded or Plain
Key components The transformer The transformer powers the killing grid, which electrocutes the flies The step up transformer coverts the European standard 230v mains supply to around 3,750v If touched, the killing grid is not fatal to humans as the transformer also steps down the current to less than 0.01A The spark created by the transformer can be tested by touching the killing grid with a grid tester A transformer
3. Key components Ballasts and starters The ballast (choke) regulates the current from the power supply With no ballast, a florescent tube would draw too much current & blow There are two technologies of ballasts used within EFKs 1. Magnetic ballasts and starters 2. Electronic ballasts Magnetic ballasts work in conjunction with a starter Starters give the UV tube an extra surge of power to initially ignite Magnetic ballasts create a high frequency flicker, invisible to humans, but which helps attract flying insects Electric ballasts do not provide this attractive flicker
Flykiller Technical Training Course 4. Flykiller design and area coverage R2 29/08/13
5. Flykiller design basic principles Using high quality components is important to maximising the efficacy of a flykiller UV Tubes Glueboards Ballasts However, these components will have no impact in a badly designed flykiller Clearly to attract more flying insects, quicker, we must maximise the UV irradiance from the product design The position of the UV tubes and openness of the design make a significant impact on the irradiance emitted from the product Using the in-house spectrometer measuring equipment, we can measure fill 360 irradiance from flykiller products Exocutor (30w) Allure (30w) 30
The coverage area myth The most effective flykillers have the largest published area coverage Each application is unique, so it is impossible to give an exact coverage area for each flykiller Some manufacturers publish outlandish claims about the area their products cover, which is both misleading, and harmful to both their own and the industries credibility It is however possible to give a recommended coverage area, but this must be considered in conjunction with a full site survey
Area coverage guidelines Individual applications Both of these applications are 100m² Does logic really suggest they will require the same flykiller solution? INSERT PLAN OF SIMPLE ROOM INSERT PLAN OF COMPLEX ROOM No obstructions No direct light competition Non sensitive application Cooker hoods Large amounts of light competition Highly sensitive application
Area coverage guidelines Flykiller design and specification Both of these flykillers are 30 Watts Does logic really suggest they will cover the same area effectively? Design Open top Closed top Tube irradiance 368nm and 540nm 368nm Materials Polished internal sheet steel Wire / matt extrusion
Application matrix Based upon area coverage guidelines, a starting point can be recommended for the number of flykillers required
Flykiller Technical Training Course 5. Specialist environments
6. Introduction to specialist environments The market for insect control products includes specialist environments. These specialist environments include: Areas with high humidity or which require regular hosing down Eg, abattoirs Areas where there is the potential for explosive vapours Eg, flour mills Such applications are classified using two international ratings: Ingress Protection (IP) ATEX Flykiller requirements of Ingress Protection The vast majority of applications requiring an IP rated flykiller, simply need the product to be safe to be hosed down IP rated Flykillers do not come with an electric plug they must be hard wired An IP rating of IP45 and above is appropriate to meet this need
Explanation of Ingress Protection The Ingress Protection (IP) rating classifies protection provided against the intrusion of solid objects and water in electrical enclosures The first digit represents ingress of solids, and the second of water Solid Objects Water Digit Rating Digit Rating X Not classified X Not classified 0 No Protection 0 No protection 1 50mm diameter 1 Dripping water 2 12.5mm diameter 2 Dripping water at 15 3 2.5mm diameter 3 Sprayed water 4 1mm 4 Splashed water 5 Dust protected 5 Water jets 6 Dust tight 6 Powerful water jets 7 Immersion up to 1m 8 Immersion beyond 1m
Explanation of Ingress Protection Whilst it sounds nice to have the highest possible rating on both digits, in reality this is unnecessary, and adds cost to the product IP45 is appropriate for flykillers to be hosed down Solid Objects Water Digit Rating Digit Rating X Not classified X Not classified 0 No Protection 0 No protection 1 50mm diameter 1 Dripping water 2 12.5mm diameter 2 Dripping water at 15 3 2.5mm diameter 3 Sprayed water 4 1mm 4 Splashed water 5 Dust protected 5 Water jets 6 Dust tight 6 Powerful water jets 7 Immersion up to 1m 8 Immersion beyond 1m
IP Rated Flykiller Examples Splashproof 80(Excalibur Aqua) - IPX4 FTC (Flytrap Commercial) 80 IP65 - IP65 ATEX Certified Flykiller Example Insect-O-Cutor EX55 II 3 G D Halo 45 IP45
Explanation of ATEX Directive Overview Often referred to as ATEX, the ATmospheres EXplosibles legislation is in fact two European Directives which discuss potentially explosive areas ATEX Directive (94/9/EC) covers the safety requirements for equipment to be used in potentially explosive atmospheres ATEX Directive (99/92/EC) is often referred to as the 'ATEX Workplace Directive' and highlights what employers must do to minimise the risk to workers from explosive atmospheres Any equipment designed for use in potentially explosive atmospheres must be certified to meet the standards of these two EU Directives
Tube replacement in specialist flykillers For most flykillers, once you have gained access to the tubes, replacing the tube is usually a quick operation However, IP rated flykillers take a little longer, as usually the tube holder cover will need to be removed before the tube can be replaced Care should be taken to ensure the tubes are fully fitted into position, or they will not light Standard flykiller tube replacement IP rated flykiller tube replacement
Flykiller Technical Training Course 6. Site surveying - Where to install a flykiller?
Siting and surveying Every application is unique, so each situation requires an individual assessment for flykiller siting However, there are basic principals that should be followed... Recommend enough EFKs to cover the area to be protected, as suggested by the manufacturer Install EFKs away from sources of light competition, such as windows, doors and high powered luminaires Consider sources of heat and airflow, such as heaters / AC units Don t install EFKs directly above sensitive areas, such as food preparation areas Consider access for installation and future servicing
When should you use a killing grid or glueboard flykiller? When electrocuted, the insect usually implodes, with the fly carcass being retained within the catch tray However, bacteria carried by the fly can be expelled out of the flykiller when the insect is electrocuted and some body parts (wings and legs) may become airborne. Glueboards are therefore recommended for sensitive applications such as food preparation areas Killing grids Effective low maintenance insect control for high infestation areas Glueboards Silently retain the caught insect for evaluation Appropriate for areas of hygienic sensitivity Decorative Discreetly traps insects, retaining them from view of customers Ideal for front of house applications
Example siting of killing grid, glueboard and decorative flykillers
Flykiller siting Siting do s Wherever possible, flykillers should be positioned at 90 to sources of natural light, such as windows, doors and skylights Flykillers should be positioned in between potential entry points, so as to intercept flying insects before they reach sensitive areas Shatterproof tubes MUST be installed in areas operating a glass free policy An appropriate number of units should be installed to correctly protect the area in line with the suggested area coverage of the unit Glueboard units should be used in sensitive applications such as food preparation or production areas
Flykiller siting Siting don ts Flykillers should not be installed immediately above food preparation or production areas The UV light from the flykillers should not be obstructed by canopies, furniture or other hanging obstacles, and should be visible from every part of the area to be protected Flykillers should not be sited either too high or two low in the area to be protected, with an optimum height of around 2m Flykillers should not be installed where air curtains or air conditioning units can prevent the flying insect from gaining access to the machine Do not install the flykiller where future servicing will be difficult. Eg, remember that the glueboard must be able to be removed
Flykiller siting Good or bad? - Protecting door to food prep - Not directly over food prep - Mounted at correct height -???
Flykiller siting Good or bad? - Glueboard flykiller (Food) - A little too high - How to service glueboards?!
Flykiller siting Good or bad? - Industrial flykiller - Killing grid flykiller - Too high to be effective - Too high to service
Flykiller siting Good or bad? - Glueboard flykiller (Food) - Correct height - Inappropriate to service
Flykiller siting Good or bad? - Glueboard flykiller (Food) - Correct height - Protecting access point - Bad access for service
