Multiple Drying Segments Theory –Fact: Wet linens can handle more heat than dry linens. –Theory: While linens are wet, dry at high heat and gradually lower temperature to recommended drying temperature as more water evaporates and load gets dryer Multiple Drying Segments Example –Care label says: “Dry at 130°F” Without segment based drying you dry at 130°F –With segment based drying you can dry like this At 190°F until 30% moisture remaining At 160°F until 20% moisture remaining At 130°F until target moisture is reached Multiple Drying Segments

–Auto Dry calculates the drying time on the first heat cycle –OPT determines the remaining moisture based on input from the sensors throughout the ENTIRE cycle The result is that OPT is VERY accurate OPT vs. Auto Dry 75 lb Natural Gas Tumble Dryer

OPT: Over-drying Prevention Technology Reduce Labor Costs Lower Energy/Utility Costs Lower Linen Replacement Costs Maintenance Free Performance ALS Moisture Sensing Survey 79% respondents believe laundries over-dry by more than 8 minutes. 84% respondents believe that only 20% of managers realize they are over-drying.

OPT maximize throughput and minimize operating cost Labor Cost is 50% on Every $1.00 Laundry facilities are less efficient due to over-drying. Reducing over- drying can: – Increase throughput –Decrease cycle times –Reduce utility waste –Lessen the frequency of linen replacement due to reduced fabric wear. OPT is also valuable in WET cleaning applications where accurate moisture is important for fabric conditioning.

Efficiency Drying efficiency is often defined with terms like “gas usage” and “input Btus” –Reducing utilities doesn’t address a laundry most significant expense—Labor On average laundry facilities spend 10 times on labor cost as they do on utilities

Over-drying costs tumblers users utilities and throughput. OPT can reduce utility costs and increase throughput. If a laundry facility is over-drying by 8 minutes per load with a 75 lb tumbler, OPT can save: $883 per year in natural gas utilities $4,867 per year in labor If the laundry can process just one more load per day with a 75 lb tumbler for the duration of a year with a 75 lb: The laundry can process an extra 18,250 lbs per year by the Numbers

The Cost of Over-drying

Linen replacement cost can range between 18-25% of the laundry dollar. When over-drying is eliminated linens experience 31% less fiber loss. Affect on Linens *According to ALS lab tests

How OPT Works OPT measures the conductivity of the load –Measurement is read between a maintenance free electrically isolated lifter and the cylinder wall. As the load dries, conductivity decreases. –The conductivity signal (wetness) of the load is transferred from the rotating cylinder to a rotational switch located in the center of the cylinder bulkhead. – The maintenance free rotational switch transfers the signal to stationary wires. The wires transfer the signal to the control. – The control reads the moisture level of the load. – The control discontinues drying when the user set remaining moisture content is attained
