SANITIZING
B-US 283 LPW
FLIGHT-TYPE
WAREWASHERS
Meiko's flight-type conveyors are the ideal choice for highvolume applications. They feature dramatically improved
water savings and Meiko’s exclusive Chemical Savings
System (CSS) that reduces detergent consumption from
30-50 percent.
Other standard features include computer-positioned wash
and prewash arms that are pre-assembled into easilyremoved manifolds. Nozzles are slotted and concave to
minimize clogging, and feature captivated end caps which
can’t be lost during cleaning. A double-wall, insulated, flush
stainless steel exterior is present on all sides to conserve
energy and improve the working enviroment. Meiko’s
exclusive, optional Waste Air Heat Recovery System is
available on all models. This system eliminates the need for
the final hot water rinse to be supplied by an external water
heater, and dramatically improves energy efficiency.
As with all products synonymous with the name “Meiko,” engineering excellence, manufacturing quality and performance
come to the forefront in the B-US 283 LPW flight machine.
B-US 283 LPW
Model B-US 283 LPW includes: prewash section, two wash sections, recirculating rinse section, pumped auxiliary rinse
zone, pumped fresh water final rinse.
Standard Features:
• Low NSF-rated water consumption
• High capacity
• Large opening (21-5/8” H x 28-1/2” W) accommodates
sheet pans and other large ware
• Pumped auxiliary rinse
• Pumped fresh water final rinse
• Built-in booster heater (steam or electric)
• Standard Chemical Savings System (CSS) Basic reduces
detergent consumption by up to 30%
• Flush stainless steel exterior panels with double-wall,
insulated construction
• Central control panel with simple electro-mechanical controls
• Start/stop controls at both ends of the machine
• Two-speed conveyor - adjustable during operation to
accommodate varying levels of soil
• Stainless steel prewash, wash and recirculating rinse pump
assemblies with vertically-mounted, self-draining pumps
and powerful 3 hp motors
• V-shaped prewash, wash and recirculating rinse tanks for
faster draining and easier cleaning
• Block-manifold wash arms for fast removal and cleaning
• Tethered or “captivated” wash arm end caps
• Slotted, concave, non-clogging wash arm nozzles
• Large, balanced front access doors stay open without latching
• Contacts for external fan control, detergent and rinse aid
dispensing systems
Options:
• Waste Air Heat Recovery System - utilizes heat generated
by the machine to heat the incoming fresh water. This
utilizes “free” energy, eliminates the need for an external
boiler or water heater, and allows the machine to use an
incoming water supply with temperatures as low as 50°F
• CSS Top - additional pre-flushing system prior to the
prewash, that includes cyclone separators to actively
remove food soil from the recirculated water in the machine.
The additional pre-flushing nozzles help to reduce the need
for thorough pre-scrapping of ware by the dishroom staff.
In addition, reducing the overall soil level of the wash water
improves washing performanceand reduces detergent
consumption by up to 50%
• Steam or electric tank/booster heat
• Single blower dryer (steam or electric)
• Dual blower dryer (steam or electric)
• Low-ceiling configuration (side vent and lower-opening front
access doors)
• Split, hinged front access doors
• Load and unload ends in various lengths
• Conveyor belts in varying configurations to accommodate
special ware
