Overview
Halton Capture Jet™ hoods and ventilated ceilings are all suitable for LEED (1), BREEAM (2), DGNB (3), RE2020 (4) 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..
Description
The Capture Jet™ technology enables significant reductions in airflow rates leading to savings on construction costs, mainly due to the reduced size of ducts and HVAC equipment. It typically pays for itself upon the startup of the kitchen or within few months. The energy savings it generates then directly contribute to an increase in profitability, while the staff benefits from improved working conditions.
KVF hoods are also equipped with a low-velocity makeup air built into the front face.
Considerable energy savings
- The Capture Jet™ technology allows for up to a 40% reduction in exhaust airflow rates.
- The combination with M.A.R.V.E.L. airflow and energy optimization technology allows for reducing the exhaust volumes by up to an additional 44% on top of that of the Capture Jet™ resulting in up to a 64% total reduction. Energy savings are then massive.
- It generates important energy savings on cooling/heating the makeup air (less air out, less air in!).
- The reduced draft risk and noise levels improve the working conditions for the staff.
Improved safety and maintenance savings
- 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 cyclonic 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. It also results in savings on the ductwork cleaning cost.
Other features and benefits
- Construction compliant with NF EN 16282-2 (5).
- HACCP (6) 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.
- 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.
- Better capture efficiency and comfort for the staff thanks to a low-velocity diffuser built into the front.
- Capture and containment efficiency tested in accordance with the ASTM 1704 standard.

Construction
![](https://www.halton.com/wp-content/uploads/dita/kvf_en/1720605748/Drawings/Draw_Construction_KVF.png)
- Visible outer envelope in stainless steel AISI 304 (1,0 mm).
- Exhaust plenum.
- KSA aerosol separators.
- Condensates drain.
- Collection tray as an option.
- Exhaust connection(s) and sliding damper(s).
- When the kitchen is equipped with M.A.R.V.E.L. airflow and energy optimization technology (MRV), the sliding damper is replaced by ABD automated balancing slim damper.
- T.A.B.™ (Testing And Balancing) pressure port(s) for quick airflow calculation during ductwork balancing operations.
- Front Capture Jet™ nozzles.
- Double skin sides.
- Side Capture Jet™ nozzles.
- Integrated Capture Jet™ fan.
- Halton Thermal Imaging sensor for the optional FireWatch or M.A.R.V.E.L. technologies *.
- Halton Skyline LED culinary LED light fitting integrated on a flush-mounted access hatch.
- As an option, Halton Skyline LED spots integrated on a full width and flush-mounted light beam(s).
- Makeup air plenum.
- Perforated front face with honeycomb structure for a low velocity makeup air.
- Personal supply air nozzles.
- Supply air connection and adjustment damper (type MSM).
* M.A.R.V.E.L. or FireWatch options require controlers that are typically installed on the top of the light fittings.
M.A.R.V.E.L. ready option: To allow for later installation of M.A.R.V.E.L. airflow and energy optimization, each hood can be equipped only with its ABD slim automated balancing damper, which is typically very difficult to install afterward.
[KVF-M]
Instead of two hoods mounted back to back, KVF hood is also available as in a monobloc version for island cooking blocks.

Notes:
- Above 3100 mm, hoods are an assembly of separate sections to make transportation and site handling easier.
- 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.

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.
KVF 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. The variation in exhaust airflow reduction for a given hood type is due to the makeup-air type (mixing or displacement). Other parameters do impact the final airflow rates.
