Overview

UWI | Capture Ray™ and Water Wash hood (CE)

Applications

Halton Capture Jet™ hoods and ventilated ceilings are all suitable for LEED (1), BREEAM (2), DGNB (3), etc. projects, particularly when combined with M.A.R.V.E.L. airflow and energy optimization technology. They can be used in all closed, opened, or show kitchens, and, in general, all food-producing environments.

UWI hoods are also equipped with the Capture Ray™ and Water Wash technologies. Combined with the Capture Jets, the Capture Ray™ technology is more typically used for commercial kitchens whose ducts are difficult to access for cleaning, as well as for kitchens located in classified buildings with strong fire safety requirements or with close proximity with the neighborhood. As for the combination with the Water Wash technology, it is particularly suitable to kitchens that have in addition a large opening hours range, with little time for filters cleaning.

Description

The Capture Jet™ technology is based on the use of one or several sets of dual or single nozzles strategically placed. They prevent the smoke, steam, heat, etc. released by the cooking appliances from escaping. It therefore increases the capture efficiency of Halton's hoods and ventilated ceilings, in order to reduce the exhaust airflow rates.

UWI hoods are equipped with dual nozzles on the front and sides.

The Capture Ray™ technology neutralizes the grease particles, grease vapors and a portion of the VOCs carried by the exhausted air. It drastically limits the grease deposits formation inside the ductwork that represents a major risk on fire safety and ducts hygiene. The airborne cooking odours will be also so minimal that it can negate the need to discharge the air at high level from the building to not annoy the neighborhood.

The Capture Ray™ technology allows for safely establishing kitchens in premium locations, while saving on operating costs.

The Water Wash technology is designed to automatically carry out the regular filters cleaning, with no outside intervention necessary. It cuts down the filters cleaning frequency to the strict legal minimum. It saves a lot on the maintenance costs. Users can also devote themselves entirely to creating and preparing menus and food.

Considerable energy savings

  • Up to a 40% reduction in exhaust airflow rates thanks to the Capture Jet™ technology.
  • The Capture Jet™ technology typically pays off from installation or within a few months after, thanks to the reduction of the construction and operation costs.
  • M.A.R.V.E.L. airflow and energy optimization technology allows for reducing the exhaust volumes by up to an additional 40% on top of that of the Capture Jet™ resulting in up to a 64% total reduction.

Improved safety, maintenance savings and respect for the neighborhood

  • KSA cyclonic aerosol separators constructed of stainless steel in compliance with EN 16282-6. They are up to 95% efficient on 10 microns particles or larger. Also certified UL 1046, NSF, and LPS 1263.
  • KSA aerosol separators efficiently slow down the build-up of grease deposits in the exhaust plenums and ductwork that could otherwise constitute a serious hygiene and fire safety hazard.
  • The Capture Ray™ technology neutralizes the grease vapors and the remaining grease particles. The exhaust plenum and ductwork are virtualy free of grease deposits.
  • The ductwork cleaning operations are cut down to the minimum legal frequency (if applicable) or to the strict minimum, leading to important savings.
  • Hygiene and fire safety are also at an optimum level.
  • The Water Wash technology automatically cleans the filters with no staff intervention.
  • The Water Wash technology adds savings on filters cleaning cost on top of the savings on ductwork cleaning. Hygiene, fire safety and savings are at the highest possible level.
  • The Capture Ray™ technology also reduces drastically the odors emissions and enables establishing restaurants in dense urban sites.
  • The UV On Demand option activates the lamps only when cooking appliances are actually used. It saves up to one lamps-set where other UV systems require two.

Other features and benefits

  • HACCP (4) International certified.
  • Integrated fan for the Capture Jet™ technology. No additional duct is required.
  • Capture Jets are automatically switched off when the hood is not used or operates at a minimum airflow.
  • Total access security to UV-C lamps that includes the detection of each filter presence.
  • Requires a control cabinet from CCW range for the automatic washing cycles management.
  • Advanced 24/7 distant monitoring capabilities thanks to Halton Connect IoT (Internet of Things) platform.
  • Highest value of ownership thanks to Halton Connect & Care smart services available as an option from kitchens commissioning.
  • Halton Skyline (HCL) LED culinary light provides the best visual comfort while contributing to further improve safety and energy savings.
  • When extended to the whole kitchen and surrounding areas, the Human Centric version of Halton Skyline (HCL) directly contributes to chefs' and their teams wellbeing.
  • Capture and containment efficiency tested in accordance with the ASTM 1704 standard.

About Halton Skyline



Halton Skyline is the first LED based lighting technology specifically developed for commercial kitchens. Everyone agrees the light it provides is simply the closest possible to natural light. Halton Skyline is embedded in Halton's hoods, ventilated ceilings and hard false ceilings. Also available as standalone light fittings, its use can be extended to all areas of kitchens. Halton Skyline represents a unique set of real benefits for the chefs, their staff and even their guests when it comes to display kitchens.

  • A Culinary Light that remarkably respects the food colour and plasticity from raw ingredients to plated presentation

  • A Culinary Light that also improves the working conditions while playing an active role in the kitchen safety

  • A Human Centric light that follows your biorhythm to further improve the working conditions and staff Wellbeing

  • A state-of-the-art lighting technology that, at its core, saves significantly on energy and maintenance

Construction

  1. Visible outer envelope in stainless steel AISI 304 (1,0 mm).
  2. Exhaust plenum fully constructed of stainless steel AISI 304 (1,2 mm).
  3. KSA aerosol separators.
  4. Removable deflectors.
  5. Water drain threaded pipe (DN50).
  6. UV-C rack mounted on runners for an easy removal.
  7. UV access hatch for a quick access to the UV lamps for cleaning.
  8. Stainless steel manifold equipped with brass spraying nozzles for the filters cleaning (hot water).

- Number of connections to be determined based on the sections length and on the calculation of the airflow rates depending on the cooking appliances.

- Rectangular connections on request.

Admissible and calculated airflows

Admissible airflows

(1) QE Min/KSA = 505 m3/h | QE Max/KSA = 786 m3/h - ∆PT.A.B. Min = 59 Pa | ∆PT.A.B. Max = 144 Pa

(2) Side Jets with W=1300 mm

Calculated airflows

The calculated exhaust airflow rates are determined with a EN 16282-1 based calculation method. It relies on the evaluation of the convective flows' volume (air mixed with heat, steam, grease, smoke and other pollutants) generated by the cooking appliances, depending on their type, on the energy they use and their installation conditions (central, on a wall, in an angle).

The air volume required to remove the convective loads is then calculated depending on:

  • The hood or ventilated ceiling installation height;

  • The makeup-air strategy (mixing or displacement);

  • The hood or ventilated ceiling capture efficiency according to ASTM 1704-12 standard.

UWI hood reduces the exhaust airflow rates(1) by up to 40% compared to traditional hoods.

(1) This scale is indicative and based on wall mounted hoods, opened on 3 sides, equipped with a same cooking bloc, whatever it is. For each hood model, the exhaust airflow variation is due to the makeup-air type (mixing or displacement). Other parameters do impact the final airflow rates. Our sales teams are at your disposal to provide you with a calculation note depending on your kitchen configuration.
