Universal Ventless Hood
MODEL WVU-48

Model WVU-48

DESCRIPTION

Wells Universal hoods are Certified Type-1 compliant, UL710B approved 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 ductwork are impractical, restricted or too expensive. Operators can mix and match various electric cooking equipment under the hood such as fryers, ovens, griddles, steamers and more – providing greater flexibility and through-put.

SPECIFICATIONS

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. Front access for easy fire system maintenance. 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’s 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, fiberglass pre-filters, HEPA (High- Efficiency Particulate Air) filter/ carbon-charcoal filter pack. Al filters are easily removable with out tools. Air flow sensors continually monitor air flow optimizing performance and grease removal while aninterlock system will not allow cooking appliances to  function if filters are missing, clogged or in the event of a fire.

Cooking Appliances – Only electrically heated appliances are acceptable for installation. Cooking equipment is optional from Wells or other manufacturers. Appliances must be installed as per manufacturers instructions and controlled thru the hood equipment  shut-off interface through a customer supplied contractor which will disable cooking equipment in the event of fire or hood malfunction. For size, temperature and KW limits see back page or manual.
Exhaustand Air Flow – Exhaust air may be horizontal or vertical. Hoods are shipped for horizontal discharge and are field convertible for vertical discharge. Typical airflow is 1,500 CFM. A minimum of 800 cubic feet of fresh air per minute is recommended both  in and out of the cooking area to ensure the dilution of cooking aromas.
