Construction

The KFM hood comprises a Capture Jet™ air supply module, a light fixture, adjustment dampers, airflow measurement taps and KSA grease filters. All parts of the hood are manufactured from polished stainless steel EN 1.4301 (AISI304). The Capture Jet™ supply plenum is thermally insulated through the use of mineral wool material to prevent condensation on the inner face above the cooking equipment. The hood is equipped with removable grease cup for collection of the grease.

Function

  1. Supply air enters the Capture JetTM plenum.
  2. Contaminated air and heat rises from the cooking appliances.
  3. Contaminated air is directed into the hood by Halton patented Capture JetTM technology.
  4. KSA multi-cyclone filters remove grease and contaminants from the air stream with the aid of centrifugal effect. According to independent laboratory tests KSA is the most efficient mechanical grease filter on the market.
  5. Filtered exhaust air.

Specifications

Suggested specification

General

The galley hoods shall be constructed from stainless steel EN 1.4301 (AISI304). The galley hoods shall be supplied complete with outer casing / main body, airflow measurement taps, exhaust air spigot connection with adjustment damper, maintenance hatch, light fixture, grease filters, grease cup. Classified fire damper in each exhaust connection. Classified fire damper in each exhaust connection is available as an option. he manufacture of all galley hoods shall be controlled by ISO 3834-2:2005, ISO 9001, 14001 and OHSAS 18001 standards. The design of hoods shall follow USPHS guidelines.

Construction

All parts shall be constructed of stainless steel sheet (thickness 1.25 mm) with a polished finish. The inside corners of the hood are rounded for easy cleanability according to USPHS guidelines. The joints at the lower edges of the device are welded. All visible screws are thumb screw type. The hood is equipped with a grease cup for removing the grease. There is a maintenance hatch in each hood for easy access above the hood.

Capture Jet plenum

The Capture JetTM plenum shall be insulated with sealed mineral wool. Plenum can be accessed through a maintenance hatch(es).

Capture Jet system

The hood shall be designed with Capture JetTM technology to reduce the exhaust airflow rate required and increase the capture and containment efficiencies of the hood, while reducing energy use.

Airflow measurement taps

Measurement taps shall be located on top of the hood for supply air and exhaust air measurement.

Halton KSA filter

  • Minimisation of grease deposits in the ducts
  • Enhanced hygiene and safety

The KSA grease filters shall be constructed of stainless steel. The grease filters shall be supplied in modular size of 500x330x50 mm and shall be removable via two folding handles. The grease filters shall have a honeycomb design in order to allow high grease filtration efficiency with the aid of centrifugal effect in filter honeycombs.

Mechanical filtration is recommended to be used in hoods with low utilization rate and cooking process producing mainly large grease particles (> 8 microns), e.g. food prepared with gas fryers, griddles and broilers (source ASHRAE).

Duct connections

The duct connections and adjustment dampers for exhaust air shall be constructed from stainless steel. The dampers shall be adjustable.

Light fixtures

Each hood shall be delivered with a fluorescent light fixtures or LED light fixtures providing approx. an average illuminance of 500 lux at the work surfaces of the cooking appliances. The light fixtures shall be suitable for a single-phase 230-VAC power supply and shall be manufactured to be of protection class IP67. The ballast and capacitor shall be located within the light frame. The core electric cables connecting the light fixture to the junction box shall be provided.The light fixture shall be installed on a hinged maintenance hatch, allowing access to the hood roof.
