HOT WATER SANITIZING
MULTIPLE-TANK
B-US 232 LPW
FLIGHT TYPE
W AREWASHER
The clean solution
Special Features:
• Narrow-belt configuration more easily fits into tighter
spaces, while accommodating common ware items such
as racked items, cafeteria trays, plates, and bowls
• Two full heated wash tanks provide true multiple-tank
washing performance, reducing the need for re-washing
items and providing greater capacity for food soil
• Dual-rinse design allows separate rinse and sanitization
areas for lower overall water consumption
• Pumped final rinse fully isolates the machine from
fluctuations in building water supply pressure, providing
more consistent results
• Rugged electro-mechanical controls are front-mounted
for convenience, with additional start/stop controls at both
ends of the machine
• Two-speed conveyor - adjustable during operation to
accommodate varying levels of soil
• CSS Basic (Chemical Savings System) reduces detergent
consumption by up to 30% by diverting used rinse water
into the prewash section, reducing food debris
contamination in the wash tank
Standard Features:
• Prewash tank with 3 HP (2.2 kW) pump
• Wash tank with 3 HP (2.2 kW) pump
• Recirculating rinse tank1 with 3 HP (2.2 kW) pump
• Auxiliary rinse zone with 3/4 HP (0.55 kW) pump
• Final rinse zone with 3/4 HP (0.55 kW) pump
• Built-in booster heater (steam or electric)
• 304-series stainless steel construction
• Fully automatic operation
• Front-sloping, V-shaped wash tank design increases
visibility and accessibility for cleaning, and improves tank
draining
• Double-wall insulated construction on front, top and back
improves operator safety, conserves heating energy, and
reduces noise and heat loss into the dishroom. Insulation
is fully waterproofed to eliminate heavy doors and
unsanitary waterlogging
• Standard lifting doors are full-width for each chamber.
Doors are balanced and spring-loaded to stay open
without latching
• Pumps are vertically-mounted to be self-draining and
easily serviced
• Block-manifold wash arms for fast removal and cleaning.
Wash arms feature slotted, concave nozzles to resist
clogging, and tethered (“captivated”) end caps
• Contacts for external fan control, detergent and rinse aid
dispensing systems
• Single-point drain and single-point indirect ventilation
connections

Optional Features:
• Waste Air Heat Recovery System - utilizes heat generated
by the machine as free energy to preheat the incoming
final rinse water. This improves efficiency and permits the
final rinse to operate from a cold water supply.
• CSS Top (Chemical Savings System) - replaces standard
CSS Basic system with a dedicated pre-flushing system
located prior to the prewash. CSS Top receives cooled
water from the auxiliary rinse zone, and pumps it over the
ware to remove food soil prior to entering the prewash.
Water is then reclaimed and filtered through cyclone
separators for improved soil removal performance. An
automatic, continuous rinsing spray removes soil buildup
from inside the loading section. CSS Top reduces the
need for physical scrapping as well as reducing wash
water contamination, which in turn reduces detergent
consumption by up to 50%.
• Steam or electric tank/booster heat
• Single blower dryer
• Dual blower dryer
• Load and unload sections in various lengths
• Conveyor belts in varying configurations to accommodate
special ware
• Drain water tempering
• Flanged, bolt-down feet
• Water hammer arrestor
• Single-point electrical connection (electrically-heated
machines only; standard on steam-heated machines)
1 Model B-US 232 LPW is approved by NSF as a multiple-tank dishwasher. The
recirculating rinse tank is a complete second wash tank. Some manufacturers
and/or models may refer to this as a power rinse tank.
This dishwasher is compliant with the Reduction of Lead in Drinking
Water Act (201 1) amendment to the Safe Drinking W ater Act (SDW A).

extended load sections. Consult MEIKO for
assistance.
Notes on custom load sections:
Load sections with a lowered loading height are
available for specific applications, such as when the
loading area is underneath a table or tray conveyor.
Consult MEIKO for details.
