Capture Jet™ Hood with Side-Jet Technology - Halton

KVI
Capture Jet Hood with Side-Jet Technology
The KVI Capture Jet hood with Side-Jet technology
is a highly efficient kitchen ventilation hood that
removes contaminated air and excess heat emitted by
cooking equipment, helping to provide a comfortable
and clean environment.
The KVI hood uses the advanced Halton Capture Jet
system, combining horizontal and vertical jets at the
front and also on the sides of the hood to improve
capture and containment of the air flows generated by
the cooking equipment, even at the end of the line.
Overall, the system requires 30 to 40% less exhaust
air volume than traditional hoods do to remove an
equal heat load.
The Capture Jet with Side-Jet technology is based
on the high entrainment of a compact, high-velocity
capture air jet. The capture air jets efficiently induce
ambient air at the critical front and side area of the
hood, minimising the spillage of the contaminated air
and maintaining good air quality in the chef’s work
area.

• Improved indoor air quality for higher productivity
with reduced energy use. Halton’s patented Capture
Jet with Side-Jet technology improves the capture
and containment efficiency of the hood, thus
reducing the exhaust air volume required.
• Performance tested by a third party in accordance
with the ASTM 1704 standard.
• High-efficiency grease filtration using UL- and NSFclassified
KSA multi-cyclone filters for removal of up
to 95% of particles with a size of 8 microns or
above.
• Standard delivery that includes lighting, integrated
Capture Jet fan, TAB (Testing and Balancing)
taps, and balancing dampers that allow accurate and
effective commissioning.
• Stainless steel construction with seamless design
for improved hygiene and fire safety.

The KVI kitchen canopy comprises a Capture Jet unit
with side jets, a Capture Jet centrifugal fan
(optional), an IP65 light fitting, adjustment dampers,
airflow measurement taps and a KSA grease
separator.
All visible parts of the canopy are manufactured from
polished stainless steel AISI 304 and the unexposed
parts from galvanised steel. Joints on the lower edge
are fully welded.
A collection tray or a drain tap is fitted into the grease
drain channel in order to enable the removal of the
grease and dirt extracted by the KSA multi-cyclone
separator.
The Capture Jet air plenum is thermally insulated
using non-fibre-releasing material to prevent vapours

Testing and balancing taps (TAB) for flow
measurement are fitted to the exhaust plenum and
the Capture Jet air plenum.
The new Capture Jet family is manufactured in the
form of modular sections. Large canopies are
assembled using a combination of separate modules
without any beams between the modules, meaning
that one long section is created, which is aesthetically
preferable.
The modular sections make transportation and site
handling easier.

Function
The kitchen canopy above cooking appliances contains
the rising warm air and contaminants (A).
The Capture Jet (B) increases the efficiency of
capture of the smoke and contaminated air at both the
face and sides for enhanced performance at the end
of the cooking line and directs the contaminated air

Suggested specifications
The kitchen hood shall be constructed from 1.0-mm
AISI 304 stainless steel.
The kitchen hood shall be supplied complete with
Capture Jet technology, high-efficiency multi-cyclone
grease filters, pressure measurement taps, exhaust air
spigots with adjustment dampers, and a fluorescent
light fitting with installation hatch.
The size shall be as indicated in the drawings.
Outer casing
• Outer casing panels are constructed from AISI 304
stainless steel in a brushed satin finish in a modular
construction. The joints of the lower edge shall be
fully welded to be liquid-tight, avoiding harmful
dripping of condensation. All exposed welds are
ground and polished to the original finish of the
metal.
• The bottom edge of the exhaust plenum should be
aerodynamically designed (no flat surface or
bounce).
• Canopy ends shall be of double-sidewall construction
(no single wall permitted).
Exhaust
• The exhaust air flow will be based on the convective
heat generated by the appliances underneath each
canopy. Submittal shall include convective heat
calculations based on the input power of the
appliance served.
• The hood’s mounting height shall be in accordance
with the drawings supplied, as a moderate increase
in exhaust rate is required if the hood is installed
higher than designed.
KVI - Capture Jet Hood with Side-Jet Technology
10
Capture Jet with side-jet technology
• The hood shall be designed with Capture Jet
technology and Side-Jet technology to reduce the
exhaust air flow rate required and to improve the
capture and containment efficiency of the hood not
only at the front but also on the sides of the canopy,
while reducing energy consumption. The Capture
Jet air shall be introduced through a special
discharge panel and shall not exceed 10% of the
calculated exhaust air flow. The Capture Jet
discharge velocity shall be, at minimum, 8 m/s. Slotor
grille-type discharge shall not be used. The
Capture Jet chamber is to be insulated.
• The hood shall be supplied with a Capture Jet fan
to provide the required air flow at the indicated
static pressure. The fan is to be provided by the
hood manufacturer, so an additional supply air
system is not required for the Capture Jet system.
Grease filters
• The hood shall be equipped with a KSA-model multicyclone
stainless steel grease extractor. The grease
extraction efficiency is 93% for particles with a
diameter of 5 microns and 98% for those with a
diameter of 15 microns or larger, as tested by an
independent testing laboratory. The pressure loss
over the extractor shall not exceed 120 Pa at the
flow rates calculated. Sound levels shall not exceed
an LpA rating of 50 dB(A). The filter shall be NSFand
UL-classified. Baffle- or slot-type grease
extractors shall not be used.
TAB ports and air flow balancing
• The air flows through the KSA separator and the
Capture Jet air chamber are to be determined via
the integral TAB ports mounted in the hood. The air
flows are to be determined by the pressure vs. air
flow curves supplied by Halton.
• The replacement air shall be delivered with a supply
control damper of type MSM.
• The spigot connections for supply and extracted air
shall be supplied with a sealing gasket and air-flowbalancing
damper plate.
20/KVI/0000/0408/EN

Light fixtures
• Each canopy shall be provided with a fluorescent
light fixture to provide approx. 500 lux at the cooking
appliances work surface. The light is protected with
a stainless steel hatch with plain milled finish,
surrounded by a tempered-glass light diffuser (the
heat tolerance of the glass shall be -40 to 300 ˚C).
The hatch shall be hinged and held in position with
screws.
Fire suppression system
• The kitchen hood fire extinguishing system shall
protect the kitchen hood against grease fires
through a completely automatic fire control system
of the wet chemical type. The fire detection system
shall be capable of detecting fire in the hood, duct,
or surface equipment and shall automatically
discharge liquid extinguishing agent into the plenum
chamber, exhaust duct collar, and cooking appliance
areas to eliminate the possibility of re-ignition or
re-flash. System components shall include a springloaded
release mechanism, agent tank brass nozzles
with blow-off caps and stainless steel appliance
drops, a fusible link detector, wall-mounted
emergency pull stations, a wall-mounted automan
and cabinet, and a mechanical gas valve installed in
the gas line serving the cooking equipment (valve
provided by the fire protections system
manufacturer and installed in the gas line by a
plumber). The system’s installation shall be
performed by an authorised representative of the
system manufacturer and conform to UL 300
requirements and local codes.
