Meiko's flight-type conveyors are the ideal choice for high-volume applications. They feature dramatically improved water savings
and Meiko’s exclusive Chemical Savings System (CSS) that reduces detergent consumption from 30-50 percent. As with all products
synonymous with the name “Meiko,” engineering excellence, manufacturing quality and performance come to the forefront in the
B-US 23 Series flight machines.
• Model B-US 231 includes: wash section, pumped auxiliary rinse zone, pumped fresh water final rinse.
• Model B-US 231 PW includes: prewash section, wash section, pumped auxiliary rinse zone, pumped fresh water final rinse.
• Model B-US 231 LPW includes: large prewash section, wash section, pumped auxiliary rinse zone, pumped fresh water final rinse.
• Model B-US 232 LPW includes: large prewash section, wash section, recirculating rinse section, pumped auxiliary rinse zone,
pumped fresh water final rinse.
• Model B-US 233 LPW includes: large prewash section, two wash sections, recirculating rinse section, pumped auxiliary rinse
zone, pumped fresh water final rinse.
Exclusive Features:
• Optional Waste Air Heat Recovery System utilizes heat
generated by the machine to heat the incoming fresh water.
This utilizes “free” energy and allows the machine to use an
incoming water supply with temperatures as low as 50°F.
• Insulated double-wall construction on doors, front, top
and back
• Pumped auxiliary rinse supplements the pumped fresh
water final rinse
• Standard Chemical Savings System (CSS) Basic reduces
detergent consumption by 30% (based on Meiko’s low water
consumption)
• Optional CSS Top reduces detergent consumption by 50%
Standard Features:
• Low NSF-rated water consumption
• High capacity
• Built-in booster heater (steam or electric)
• Central control panel with simple electro-mechanical controls
• Operator-activated start/stop controls at both ends of machine
• Two-speed conveyor
• Stainless steel wash pump assemblies with vertically-
mounted, self-draining pumps and powerful 3 hp motors
• V-shaped wash tanks for faster draining and easier cleaning
• Block-manifold wash arms for fast removal and easier 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 and external transport control
Options:
• Waste Air Heat Recovery System
• Single blower dryer (steam or electric)
• Dual blower dryer (steam or electric)
• CSS Top
• Load and unload ends in various lengths
• Steam or electric tank/booster heat
• Factory-installed external fan controller

• Heated auxiliary rinse zone utilizes fresh water a second time as a pre-rinse to provide pristine results.
• Horizontal clearance of 1’ 11-3/8” (600mm) and a vertical clearance of 1’ 3-3/4” (400mm) throughout the machine.
• Double-wall insulated construction to reduce heat loss, outside surface temperatures, and noise pollution.
• Flush stainless steel exterior panels on front, top and back.
• Front-sloping, V-shaped wash tank design to increase visibility and accessibility for cleaning as well as ensure complete
tank draining.
• CSS Basic (Chemical Savings System) reduces detergent consumption by 30% by diverting used rinse water into the

Unit will have these optional features:
____ Meiko’s exclusive “Waste Air Heat Recovery System” which utilizes the heat generated by (and normally exhausted
from) the machine as free energy to preheat the incoming rinse water. In addition to saving energy, this feature
allows the use of incoming rinse water with temperatures as low as 50°F (10°C).
____ Meiko’s exclusive CSS Top (Chemical Savings System) - a dedicated pre-flushing system located prior to the
prewash that receives cooled water directly from the auxiliary rinse zone. CSS Top flushes food debris directly
from the ware and removes food soil by filtering the water through two cyclone separators. This reduces wash
water contamination, reducing detergent consumption by 50%.
NOTE: The CSS Top option is not available on Models B-US 231 and B-US 231 PW.

B-US 23 Series • Updated 11-04 Meiko • 917 Airpark Center Drive • Nashville, TN 37217 • (800) 55-MEIKO • FAX (615) 399-6620 • www.meiko.us
Meiko’s flight conveyors use
double stainless steel walls, with
a layer of insulation between them.
This keeps heat inside the
machine, reducing energy
consumption while improving the
working environment by reducing
noise and heat dissipation into the
dishroom.
Prewash and wash arms are assembled into easily-removed
block manifolds, simplifying cleaning. The arms are also fitted
with tethered (or “captivated”) end caps to prevent their loss
during cleaning. Large, front-sloping stainless steel scrap screens
are easily removed for cleaning.
Now you have a choice!
Compare, and the
choice is obvious!
Meiko’s optional Waste Air Heat
Recovery System uses the waste
heat generated by the machine to
pre-heat the incoming rinse water.
In addition to saving energy, the
system allows the use of incoming
water as cool as 50°F/10°C!
Meiko’s flight conveyors have a pumped final
rinse to eliminate pressure fluctuations and
ensure consistent, pristine results.
Used rinse water, instead of cascading directly
into the wash tank, is regenerated and diverted
to a pumped, heated auxiliary rinse.
Water and chemical consumption can be significant long-term expenses
when operating a warewasher. Meiko’s B-US Series has the lowest water
consumption rate in the industry. Our exclusive CSS (Chemical Savings
System) reduces detergent consumption by 30%-50%.
Note: All specifications are subject to change without notice
based on Meiko’s dedicated product improvement program.
