PulseFlow and Conventional CBW Batch Washers ®

On very rare occasions an evolution takes place that makes everyone stop and notice. Revolutionizing Laundry Processing Technology

CBW PulseFlow Batch Washers ® The History Since their introduction in the 1960s, tunnel washers Pellerin Milnor 05: PulseFlow Technology have saved water, energy, and labor. In 1979, Milnor introduced its True Top Transfer CBW batch washer 20: Solid Welded Partitions and has been a worldwide leader in tunnel washing since. With other innovations such as Solid Welded Partitions, Double Drum Construction, and High Mechanical Action, our productive and efficient equipment is unrivaled. In our continuing efforts as an industry leader, we introduced our latest CBW washer innovation in 2009… 22: Double...

PulseFlow Technology Benefits Pellerin has developed a revolutionary, patent-pending system—PulseFlow Technology — which successfully implemented in health care, hospitality, and linen supply applications worldwide. The superior soil removal and rinsing performance of PulseFlow Technology has been verified by independent testing laboratories and has earned a Hohenstein Certificate. PulseFlow Technology in a new Milnor CBW washer offers: • Lowest Water Consumption • Enhanced Chemical Performance • Low Energy Usage • Faster Washing Introducing Milnor’

’s Proven CBW® PulseFlow® Technology.

PulseFlow Technology Milnor’s PulseFlow Technology CBW washer (patents pending) retains all the proven features that have made the Milnor CBW washer a market leader for over 30 years. The PulseFlow concept now improves upon that technology with increased productivity, reduced utilities, more efficient use of chemical energy and the lowest possible amount of water. PulseFlow Technology combines traditional True Top Transfer with a standing bath and controlled intermittent counterflow in every process module. For the greatest part of each cycle, processing without counterflow creates standing baths...

Milnor's PulseFlow Technology is a unique but simple solution for faster and more water-efficient washing in a Continuous Batch Washer. MODULE A MODULE B MODULE C Time (Modules) Proven Milnor Top Transfer (TT) design still leaves the dirty free water behind for immediate dilution upon each transfer. Now, with Milnor's PulseFlow Technology, we simply stop counterflow completely for the first 65-75% of each transfer cycle a then pump the entire amount of counterflow water at a very fa rate in the final 25-35% of the time remaining (see diagram above' The pumps are high-volume, variable speed inverter-driven...

(Vigorous, High-Flow-Rate Intermittent Counterflow) This chart represents the chemicals in successive modules. first module, soil concentration is at its highest level. With traditional counterflow (descending white line) the dirt is removed immediately and quickly. (T)With PulseFlow technology, the counterflow is delayed for approximately 70% of the cycle time, allowing for extra chemical time at full strength (green line). cycle time, the PulseFlow pumps are activated to provide a vigorous high- volume counterflow (blue line). (3) Then transfer occurs using top transfer (purple line). programmed...

B. Lowest Water Consumption Milnor PBW™ washers achieve very low fresh water consumption—less than any other tunnel washer. For light soil linen, the expected water consumption is 0.3 gal/lb (2.5 L/kg) of linen processed. For most heavy soil linen, the expected water consumption is 0.5 gal/lb (4 L/kg). PulseFlow Technology saves water with these features: • Interrupted Counterflow: Water only flows for rinsing which is about the last 25-35% of each cycle. • Controlled Flow: Water is delivered by high-volume inverter pumps with vigorous flow that removes suspended soil and used chemistry faster,...

Lint Removal Screen The 430 micron wedgewire screen removes lint and other solids from the process water.

C. Enhanced Chemical Performance The PulseFlow system is able to achieve maximum chemical performance with standing bath washing and high-velocity counterflow rinsing. • RecircONE ® Pump Arrangement: High-speed water recirculation within the first module allows fast sluicing and wet-down, causing the chemistry to instantly penetrate the soiled linen. • Standing Bath: After the transfer of the goods, the counterflow is interrupted, creating a standing bath with no water flow—chemistry is not diluted. • Controlled Time: Chemicals work at full concentration from the start of each bath. And, chemicals...

Single Tank The PulseFlow tank is the single distribution point for all water to the PBW. It recovers water from the extraction device and premixes it with fresh replenishment water using a level control.

D. Low Energy Usage PulseFlow Technology reduces energy considerably, saving the user money and having a positive impact on the environment. These energy savings support our customers’ environmental stewardship and sustainability programs. A key value in today’s marketplace. • Less Water to Heat: Lower water usage (and recycling water) means less water to heat to wash temperatures. Energy to heat water is reduced significantly. • Lower Wash Temperatures: New, low-temperature chemical formulations work very well in Milnor PulseFlow CBW washers, lowering energy use even more. • Steamless Washing:...

Inverters on Pumps PulseFlow pumps are specially-engineered for lintladen water and flow rates are precisely controlled by inverters.

E. Faster Washing For over 30 years, Milnor CBW batch washers with “TopTransfer” have washed about 30-40% faster than batch washers using “Bottom-Transfer” designs. Milnor CBW washers with PulseFlow Technology wash even faster—reducing the number of modules needed to process a given capacity, reducing capital investment costs AND saving floor space! This is all possible with: • Standing Baths: Flow is paused at start of each cycle to create standing baths without dilution so chemicals work faster. Shorter process time means less wear on linen—and longer linen life. • PulseFlow Counterflow: Counterflow...
