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.
