Twin Wall
Airtherm Engineering Limited has recently completed a flue dilution installation, working closely with the consultant and contractor at Grange Farm Primary School, Coventry.
The flue system selected for the project needed to be aesthetically pleasing, discreet and blend in with the building features, so a dilution system was chosen over a traditional system, which the client was in total agreement.
Airtherm provided design calculations for the project using the latest iCalc sizing package, along with compressive technical submission and Auto Cad drawings for approval prior to manufacture and ordering of the equipment.
The flue system installed comprised of a 300mm diameter fully welded dilution header, flatk Woods bifurcated epoxy coated fan, stainless steel silencers, volume control regulators and supply and discharge louvres, situated 2m from ground level to comply with Clean Air Act Memorandum.

Considerations
Airtherm can offer a fan dilution system to suit many appliances, from modern high efficiency condensing to gas blown and atmospheric boilers, however the principal of diluting the products of combustion is to reduce the CO² content at the discharge to below 1%, CO 50ppm & NOx 5ppm (BS6644 / IGEUP/10) in line with current legislation.
There are many design considerations that must be achieved, for instance, the correct sizing of the fan unit, dilution header, inlet and discharge plenum boxes, the location to adjacent buildings, openable windows, fresh air vent pipes and final discharge height. These can be found from the Clean Air Act memorandum, IGEUP/10 or BS6644, along with other certain provisions with respect to the final discharge height which is calculated based on the total kw input load of the plant.
Good Practice
There are two methods that can be considered when designing the dilution system -
• Air is directly taken from the outside.
• Fresh air is taken from within the plant area.
We offer a design, supply and installation service for flue dilution systems, and can offer a tailored-made package to site conditions and customer requirements.

Airtherm Engineering Limited liaised with both the consultant and the contractor at all times, attending site meetings, providing comprehensive technical submission, including calculations and drawings for approval prior to manufacture of the equipment.
Our aim was to deliver a complete ventilation package to our client that was fully compliant with current legislation, and endeavour to exceed our customers expectations whilst fulfilling all the demands of installing our kitchen canopy, using our own qualified installation team.
Manufacture
The canopy was manufactured from 304 (En 1.4301) or 316 (En 1.4401) stainless steel where specified and are suitably braced to prevent product distortion.
All joints are welded and polished. The island canopy was cut, punched and folded into sub sections and factory assembled by means of computer controlled seam welds, and non-visible mechanical fixings. Systems are manufactured to the strict guidelines of DW/172, British Standards and conform to HSE for commercial Kitchen ventilation.
The system ductwork was manufactured and installed incorporating cleaning and maintenance access doors where required to fully comply with DW/144 & TR/19 standards.
Canopy Lighting
The units are designed and manufactured to deal with a wide ranging and varied commercial application, and can deal with humidity, condense rich, as well as hot and greasy environments.
These units are normally recessed into the canopy ceiling providing easy cleaning and maintenance of the unit exterior. This also helps to greatly reduce the build-up of grease and other contaminates usually associated with the commercial kitchen environment.
Recessed Incandescent Units:
• Approved for use in commercial kitchen applications
• Meet with guidelines for DW172 & HSE Guidelines
• Satin finished stainless steel matching faceplates for matching hood interiors
• Tempered prismatic glass diffusers
Fire Suppression System
The island kitchen canopy was fitted with a R102 Ansal fire suppression system which conforms to NFPA standards 17, 17a and 96 and is UL300 listed by Underwriters Laboratories Inc .
The system was supplied with nozzles, detectors, cartridges, liquid agent, fusible links, pulley tress and elbows as required for the specific commercial kitchen application at Elmhurst School.
We can undertake turn-key packages from the simply design and installation of the equipment to providing you with all necessary builders work, electrical wiring and commissioning of the complete system.
