Batch Washers
The History
Since their introduction in the 1960s, tunnel washers
have saved water, energy, and loads of labor. Since 1979,
the Milnor CBW
in tunnel washing. With innovations such as True Top
Transfer, Solid Welded Partitions, Double Drum
Construction, and High Mechanical Action, our
productive and efficient equipment is unrivaled.
As a world-leading manufacturer of laundry
equipment since 1947, Milnor knows laundry
processing. And we’ve revolutionized tunnel
washing... Again.

PulseFlow™ Benefits
Pellerin Milnor has developed
a revolutionary, patent-pending
system—PulseFlow Technology—
which has been successfully
implemented in numerous locations
in the USA and Europe. The soil
removal and rinsing performance
of PulseFlow Technology has been
verified by an independent testing
laboratory. PulseFlow Technology in a

PulseFlow™ Technology
The new Milnor PulseFlow™ Technology system offers a
major breakthrough in batch washing technology. This patent-
pending innovation retains all the proven features that have
made the Milnor CBW
and improves upon that technology with increased productivity,
reduced utilities and more efficient use of chemical energy.

with a standing bath and counterflow to occur in every module
except the last. For the greatest part of each cycle, “PulseFlow”
without counterflow, creates standing baths, so that chemicals
are allowed to do their job better without being diluted. Then,
for a very short portion of each cycle, high-velocity counterflow

is initiated—PulseFlow—thus providing the required dilution
very quickly with less water compared to full-time counterflow.
Dedicated rinse modules are not required, meaning more
production from fewer modules.

Technology offers users the best of all worlds:
• The new system creates a Standing-Bath (SB) without flow for the
major portion of each bath allowing the chemicals time to reach full
equilibrium and work more effectively.
• PulseFlow™ Technology feature retains full Counterflow (CF)
(universally accepted as the most effective rinsing method for
tunnels), using controlled, high-velocity, intermittent pumps.

Now, with Milnor’s new PulseFlow™ Technology, we simply stop the counterflow
completely for the first 65-75% of each transfer cycle and then pump the entire
amount of counterflow water at a very fast rate in the 25-35% of time remaining
(see diagram above). The pumps are high-velocity, inverter driven variable speed
so that both GPM and duration can be varied based on goods being processed.
The high-speed flow gives better wash action and uses far less water.

B. Lowest Water Consumption
Milnor CBW® washers with new PulseFlow™ Technology wash
and rinse linen at a rate of 0.6 - 0.8 gallons per pound (5 - 6.7
liters per kilogram) with a fresh water replenishment rate as low
as 0.3 gallons per pound (2.5 liters per kilogram) for light soil
processing and 0.5 gallons per pound (4.2 liters per kilogram) for
heavy soil processing.
PulseFlow™ Technology saves water with these features:
• Interrupted Counterflow: water only flows about 25-35% of each cycle.
• Pumped Counterflow: water is delivered by high-volume inverter pumps
with vigorous flow that remove soil and chemistry faster with less water.
• Dual-Use Modules: each module is used for both standing chemical baths
AND counterflow rinsing.
• Eliminates Rinse Modules: single-purpose rinse modules are eliminated.
• Better Use of Chemistry: Reduced chemicals require less water to rinse.
• Controlled Flow: inverter pumps utilize programmable time and flow
rates, keeping water use low.

• Recycled Wet-down Water: high-volume pump circulates bath water
for quicker loading and wet down.
• Full Water Availability: fresh water and recycled press water are
collected in a single tank mounted within the washer frame (under
the load scoop). No external tanks exist.
