Since make-up air is not often fully tempered and dehumidified, bring it in right at the source of where it's being exhausted.
Air curtain supply plenums introduce air near the hood to minimize mixing marginally tempered air with the fully tempered air in the rest of the kitchen.
Perforated panels evenly distribute air at lower discharge velocities which benefits hood capture and containment
Can be used as an efficient method for spot-cooling
Mounted 20” or higher above the bottom edge of the hood or flush with a drop ceiling.
External plenums can be placed on multiple sides of the hood to create a curtain of air on all exposed sides and increasing the potential volume of air that can be brought in at the hood
430 or 300 series stainless steel to match hood
14 or 18 inches wide for the air supply plenum and 24” or 28” for the split supply plenum.
Provides a thermal barrier when used in conditions that may cause condensation
