AIR JET SYSTEM INCREASES CAPTURE EFFICIENCY
Exhaust hoods with integrated air jet system contribute to substantial energy savings of the kitchen ventilation system. The system takes advantage of the induction effect which considerably increases capture and containment efficiency of the hood. In other words – by supplying around 7% of required exhaust flow rate to the air jet system, it allows to have the exhaust flow rates as much as 20% lower and maintain the same capture and containment efficiency. The air jet system helps to increase the efficiency by introducing conditioned or unconditioned air through a series of nozzles located at the opposite side of the filter bank. The jets induce multiple low velocity air streams towards the filters and provide a dual effect: first, it stabilizes the rising thermal plume by forming a vortex within the hood and propels it towards the filters.Secondly, the jets create an air „curtain“, which helps to confine the hot plume inside the hood chamber and minimizes the chances of escaping before it gets exhausted. The induction air jet system is recommended by German VDI 2052 regulation.
AIR SUPPLY SYSTEM CONTRIBUTES TO INCREASING KITCHEN COMFORT
The air supply system allows to introduce fresh make-up air to the most critical space in the kitchen – next to the cooking equipment. The feature increases comfort levels for the staff, since the fresh air is supplied directly to the most occupied zone with the highest heat loads in the kitchen. The air is supplied through a large perforated panel at low velocity, which allows to avoid drafts, minimize mixing and ensure that the capture and containment efficiency of the exhaust hood is not compromised.
PRESSURE PORTS FOR EASY ADJUSTMENT AND BALANCING
Novameta exhaust hoods come with full technical specifications– pressure drop characteristics, k-factors and recommended air flow rates. Each hood is supplied with pressure ports, which allow to determine the actual exhaust and supply air flow rates by using a simple manometer and referring to pressure drop characteristics. The feature allows to easily adjust and balance exhaust hoods according to the calculated exhaust and supply flow rates.
INTEGRATED LED LUMINAIRES PROVIDE ENERGY SAVINGS
The ultimate choice for illumination is recessed LED luminaires which offer energy savings of up to 60%! The luminaires smoothly blend into the design of each hood and provide a pleasant and uniform warm white colour light. The recessed lighting fixtue is easy to clean, heat resistant and IP65 rated. The Philips LED modules used in luminaires are designed for high operating hours and offer up to 50,000 h lifetime.
