Wells Canopy Style Hoods are Certified Type-1 compliant, UL710B compliant recirculation hood systems and feature completely self-contained air filtration system. Canopy-style hoods are available with or without completely self-contained fire suppression systems. They do not require venting outside making it possible to cook in non-traditional locations or when traditional Type-1 hoods and duct-work are impractical, restricted or too expensive. Operators may only use forward-facing, enclosed compartment appliances like single or double deck electric convection ovens, conventional ovens, combi ovens, cook & hold ovens, steamers and oven proofer combination ovens.
