Description
Function
Fresh air is supplied to the kitchen via the hood’s supply air terminal. With the adjustable comfort nozzle locatedat the front of the air terminal, kitchen personnel can direct a small amount of air in the desired direction. Contaminated air is drawn up into the hood’s efficient cyclone filter. The filtered air is then discharged via the exhaust air duct. The control air enhances the hood’s efficiency and prevents contaminated air from leaking out from under the edge of the hood.
Recessed lighting
The lighting fixture is completely recessed and approved to protection class IP 65, which means that it is dust-tight and can be exposed to water. The fixture is equipped with energy-saving LED lighting (2000, 4000 and 5000 lumens). The colour temperature is 4000 K and the colour rendering value RA(CRI) is 90.
The fixture is equipped with a 2 m extension cord with connector for easy further connection. Quick assembly with only one connection point. The fixture’s length and wattage is 710 mm / 18 W, 1310 mm / 36 W and 1610 mm / 45 W. The drive unit is equipped with support for DALI.
Design
The hood is manufactured with the desired number of sides and is delivered factory-assembled.
- Sides in stainless steel sheet metal or 3+3 mm laminated glass
- Cyklotec cyclone filter with damper and pressure tap
- Recessed LED lighting, protection class IP 65
- Integrated supply air terminals with damper, pressure tap, inspection hatch and adjustable comfort nozzle
- Control air
The integrated supply air terminals can be positioned as desired on one or more sides of the hood.
Dimensions and technical data
Dimensions
Height of hood H = 550 mm or 350 mm.
The length and depth may be freely selected. If the length x width is greater than 3000 x 1800 mm, the hood is delivered in two or more modules. The connections for supply and exhaust air have spigot connections with rubber ring seals. The height of the cover is adapted to the distance between the upper edge of the hood and the room ceiling.
h = height of cover
H = height of cover
B = depth of hood
L = length of hood
hs = height of supply air distributor
ØDT = diameter supply air connection
ØDC = diameter exhaust air connection
LC = length of filter housing
Exhaust air
The number of filter cassettes in the Cyklotec cyclone filter is determined by the exhaust air flow. For effective separation, a pressure drop of at least 20 Pa across the Cyklotec filter is recommended, which corresponds to the lower exhaust air flow rate in the table below. At the higher air flow, the pressure drop is 80-90 Pa.
| Exhaust air l/s | Number of filter cassettes | ØDC mm | LC mm |
|---|---|---|---|
| 60 - 150 | 1 | 250 | 295 |
| 120 - 250 | 2 | 250 | 295 |
| 170 - 340 | 3 | 400 | 620 |
| 215 - 430 | 4 | 400 | 840 |
| 250 - 520 | 5 | 400 | 1060 |
Supply air
The table shows how much air that can be supplied per supply air distribution unit. Each air terminal, within its flow range, is delivered set to a static pressure drop of 20 Pa.
| Supply air l/s | Height of hood | Height of supply air distributor hs | Connection ØDT mm |
|---|---|---|---|
| 50 - 110 | 350 | 260 | 200 |
| 50 - 110 | 550 | 260 | 200 |
| 90-195 | 550 | 460 | 250 |
