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