Wells Universal ventless hoods are Certified Type-1 compliant, UL710B approved ventless recirculation hood systems and feature completely self-contained air filtration and 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 use electric cooking equipment under the hood, including a fryer, griddle, hot plate and more – providing greater flexibility and through-put.
Fire Protection Completely self contained ANSUL R-102 system includes ANSUL tank, nitrogen cartridge, ANSUL sopanifier, piping, heat sensors, ANSUL drops, nozzles, and movable manual pull station. Manual pull can be relocated to the egress position or an additional station can be added by an authorized ANSUL representative. Fire protection system meets NFPA 96 Chapter 13. Fire protection system must be charged and certified by ANSUL Authorized distributor after installation and before first use (operator responsibility).
Filtration Completely self-contained filtration process reduces emissions below that allowed in NFPA 96 and ANSI UL710B using the EPA 202 test method and includes stainless steel grease baffle filter with grease cup, high-efficiency (Particulate Air) filter/ carbon-charcoal filter pack. All filters are easily removable with out tools. Air flow sensors continually monitor air flow optimizing performance and grease removal while an interlock system will not allow cooking appliances to function if filters are missing, clogged or in the event of a fire.
