KVIF/1908/UK HaltonCapture Jet technologyENERGY EFFICIENCY30 to 40% reduction in exhaust airflow rates.INDOOR ENVIRONMENT QUALITY (IEQ)The capture efficiency combined with reduced airflow ratesimprove the working conditions.SAFETYCooking vapours are not dispersed and food safety isimproved.All hoods fitted with the constantly evolving Capture Jet technology (patented) bring about a 30 to 40% reductionof exhaust airflow rates compared to classic hoods.WITH Capture JetsThe latest generation of the Capture Jet technologyrests on the association of two sets of nozzles suppliedwith an extremely low supply air volume (a maximum of30 m³/h/ml of hood). These nozzles fit to the lower part ofthe hood front as well as the sides, so as to literallyencircle the covered cooking areas.WITHOUT Capture JetsDigital simulation on the efficiency of the Capture Jets thanks to theassociation of two sets of nozzles- The horizontal nozzles increase the driving speed to thelower part of the hood front thanks to the Venturi effect.They therefore push vapours back towards the filters.It is possible to bring the reduction of exhaustairflows to 64% by combining Capture Jet andM.A.R.V.E.L technologies.- The vertical nozzles form a curtain of air that increasesthe hoods’ containment volume, protects the capturezone from draughts and considerably minimises thedispersal of vapours. Thanks to these vertical nozzles, ahood installed at a height of 2 metres is as efficient as ifit was installed at a height of 1.85 m or 1.90 m.1 Schlieren tests on a hood WITH and WITHOUT Capture JetsWITH Capture JetsThe Schlieren system shows the convectiveflows of cooking appliances so that the hoods’capture efficiency can be reliably and objectivelymeasured.KVF/IWITHOUT Capture Jets3600 m³/h3600 m³/h6000 m³/hAll vapours released by theappliances are captured andevacuated at a rate of3600 m³/h.With this same rate of3600 m³/h, a traditional hoodwithout Capture Jets isinefficient.The airflow of a hood withoutCapture Jets must be 6000m³/h in order to be consideredefficient.Capture Jet hoodWith (F) or without (I) makeup air on the front / M.A.R.V.E.L. compatible3
KVIF/1908/UK HaltonHighly-efficient KSAcyclonic filtersENERGY EFFICIENCYReduces the energy used by fans, by minimising loss ofpressure.SAFETY95% efficiency on 10 µm particles minimises build-up ofgrease deposits and improves fire safety and food safety.KSA cyclonic filters are composed of vertical honeycombsections. Opening only at the top and bottom, they aredesigned to force the air to swirl inside. The centrifugaleffect is significant and, above all, continuous – especiallyin comparison to the action of traditional filters. Particlesare thus thrown against the honeycomb walls with muchhigher force. KSA filters are 95% efficient on 10 µmparticles. Improved hygiene and fire safety thanks to less greasedeposits in the exhaust plenums and ducts. Lower maintenance costs due to lower cleaningfrequency. Improved noise levels thanks to limited pressure loss. A must for the use of UV-C Capture Ray technology.

Ideal working conditions.SAFETYThe sensible areas of the kitchen benefit from a better lightfor a better safety and quality control.ECONOMIC ADVANTAGEDrastic energy savings leading to reduced payback times.The impact of lighting in professional kitchens has oftenbeen regulated to simply satisfying illumination levelswithout regard for personnel wellbeing.safety of the staff and hygiene of the kitchen.Halton Skyline is the first LED based lighting technologyspecifically developed for professional kitchens.Everyone agrees the light it provides is simply theclosest possible to natural light.The link between good lighting, better working conditionsand productivity, is now widely recognized. However,what often occurs when a kitchen benefits from excellentlighting levels, the staff is dazzled from reflected light.When dazzling does not occur, the kitchen typically suffersfrom a lack of illumination that is more harmful for theT5 tubes Halton Skyline remarkably respects the food colour andtexture from raw ingredients to plated presentation. Thetwo spot models developed for Halton Skyline haverespectively a CRI of 83 (@4000K) and 95 (@2800K).Halton Skyline Halton Skyline provides the best visual comfort, withoutalteration over time and without dazzling the staff, thusalso playing an active role in the kitchen safety. Amongothers, Halton Skyline’s shielding angle is up to twotimes higher than DIN EN 12464-1(1) demand. Halton Skyline’s Human Centric version is a biodynamiclighting centered on users needs. It creates daylightsimilar sequences depending on the kitchen activity,further improving their working conditions andWellbeing. You would think you were outside! A state of the art lighting technology that, at its core,saves significantly on energy and maintenance. With aluminous efficacy of 120 lm/W, Halton Skylineconsumes up to 2,8 times less than fluorescent tubes.KVF/ICapture Jet hoodWith (F) or without (I) makeup air on the front / M.A.R.V.E.L. compatible5KVIF/1908/UK HaltonCulinary and HumanCentric Light(Halton Skyline)
ENERGY EFFICIENCYContributes to the exhaust airflow rates reduction achievedthanks to the Capture Jet technology.INDOOR ENVIRONMENT QUALITY (IEQ)Better working conditions and productivity thanks to a betterair quality, a draughts reduction, lower noise levels and apositive impact on the perceived temperature.Draughts have to be declared public enemynumber one.The heat and smoke generated by the cooking appliancesare extremely dispersible. When they rise up toward ahood or a ventilated ceiling, they are left to their own andare hence very sensitive to draughts. At a point that theair displacement generated by one people walking closeby is high enough to disperse them as shown below on aSchlieren test made on a hood which is not equipped withthe Capture Jet technology.HoodLow velocity makeup air from ceiling enhances boththe kitchen ventilation efficiency and the comfort.Hood C1It enables the kitchen air to be renewed on the principleof air displacement. Fresh air naturally drops to low leveland fills the working area from that level. The absence offlow turbulences prevents this fresh air from mixing withconvective flows from the cooking equipment.2In situation of total Capture, a “user” goes along s standard hood at anormal pace (1). The draught generated is enough to disperse the thermalplumes and cause spillages (2).“Mixing” diffusers are inadvisable.In narrow spaces like professional kitchens, mixingdiffusers indeed inevitably generate even strongerdraughts, harmful for the staff comfort and for theefficiency of hoods and ventilated ceilings.In addition, a comfort limit naturally appears in thekitchen’s environment through stratification. Below thislimit height i.e. above head level, air quality is optimal.Low velocity makeup air from ceiling allows not only toimprove the air quality inside the kitchen but also toimprove the Capture and Containment efficiency of theCapture Jet hoods and ventilated ceilings. It leads toenergy savings thanks to a reduction of the exhaustairflow rates.Ceiling diffusersHoodConvective flowsCooking blocKVF/ICapture Jet hoodWith (F) or without (I) makeup air on the front / M.A.R.V.E.L. compatible6KVIF/1908/UK HaltonIntegrated low velocitymakeup air

The hood shall be supplied completed and ready to beinstalled with all embedded technologies fully pre-wiredfrom the factory. The following specifications shall be fullyobserved.Exhaust plenum The exhaust plenum shall be constructed from 1.0 mmAISI 304 stainless steel in a brushed satin finish. The lowerpart of the sides shall be welded for a durable tightnessagainst condensates. All exposed welds are ground andpolished to the metal’s original finish. Its bottom edge shallbe aerodynamically designed (no flat surface) thus helping thesmoke and steam to freely rise toward the exhaust plenum,preventing steam spillage or stagnation leading to harmfuldripping of condensation. It shall be equipped with KSA multi-cyclone grease filters,constructed from stainless steel. Their efficiency shall be atleast 95% on 10 microns particles or larger, as tested by anindependent laboratory. The filters shall also be NSF and ULclassified. Baffle or slot type filters shall not be used. The exhaust connections shall be supplied with slidingbalancing dampers. The exhaust plenum shall be equippedwith T.A.B. pressure tap for quick airflow measurement.Hood outer casing Constructed from 1.0 mm AISI 304 stainless-steel in abrushed satin finish. The joints of the lower edges shall befully welded for better robustness, cleanability and a betteraesthetic. All exposed welds are ground and polished to themetal’s original finish. Hood sides shall be of double-wall construction to enablethe air supply of the side Capture Jets while reducing thecondensation risk on the internal face.Capture Jet technology The hood shall be equipped with the Capture Jet technology. Based on the use of two sets of nozzles on thelower part of both the front fascia and sides, the Capture Jetsimprove the hood capture and containment efficiency. Theexhaust airflow rates are thus reduced by up to 30 to 40%to remove the same heat load compared to the traditionalhoods, thus leading to huge energy savings. The air used for the Capture Jets shall not represent morethan 5% of the calculated exhaust airflow and the airspeed atnozzles outlet shall be a minimum of 8 m/s. Slot- or grille-typedischarge shall not be used. The hood shall be supplied with an integrated fan to providethe required airflow and static pressure for the CaptureJet nozzles operation. A specific duct is thus not requiredwhatever the model, unless contrary specification of a localcode.[Option] Integrated makeup air (KVF) To improve the staff comfort but also to optimise thecapture and containment efficiency of the hoods (thuscontributing to the exhaust airflow rates reduction), themakeup air shall be introduced into space from the hood frontfascia and at a very low velocity (less than 0.5 m/s). The hood shall be equipped with a perforated stainlesssteel front panel, combined with a honeycomb structure onthe back. This draught free diffusion complex shall be easy toremove for cleaning and maintenance operations. The internalface of the supply plenum shall be insulated to avoid any riskof condensation on the hood containment volume side. The supply connections shall be supplied with MSMbalancing dampers. The supply plenum shall be equipped withT.A.B. pressure tap for quick airflow measurement.Exhaust and supply airflow rates The exhaust airflow rates shall be determined with an EN16282-1(1) based calculation method. Hence, they shall becalculated based on the convective loads released by thecooking appliances, whether the loads are characterised bythe standard, the manufacturer or third parties’ tests, andthe installation configuration of the hood(s). The methodshall, also, in addition, consider the hood capture efficiencyaccording to ASTM 1704-12 standard. Both the exhaustairflow rates and capture efficiency shall be justified by acalculation note.KVF/I[Option] M.
Built-in Fire Suppression System (FSS) SAFETY The kitchen and the rest of the building are protected by fires being extinguished at source. Plenums and exhaust connections are also protected from the spread of fire. ECONOMIC ADVANTAGE Integration of the system in the factory to provide better respect for products and to optimise costs.
