Multiple Drying Segments
• 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
OPT vs. Auto Dry
– 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

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: Over-drying Prevention Technology
Reduce Labor Costs
Lower Energy/Utility Costs
Lower Linen Replacement Costs
Maintenance Free Performance
Labor Cost is 50% on Every $1.00
• Laundry facilities are less efficient
due to over-drying. Reducing overdrying can:

Increase throughput
Decrease cycle times
Reduce utility waste
Lessen the frequency of linen

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
by the Numbers
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
Over-drying costs tumblers users utilities and throughput.
OPT can reduce utility costs and increase throughput.
The Cost of Over-drying
Affect on Linens
• Linen replacement cost can range between 18-25%
of the laundry dollar.
• When over-drying is eliminated linens experience
31% less fiber loss. *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

New OPL Micro Control- OPT highlights
• Advanced algorithm allows for moisture level selection of
0,1,3,5,7,10,15,20,25,30,35,40%
• Additional heat time for fine tuning
• 6 Load material type selections
• ADC has 3 general moisture settings
•Miele, Electrolux/ Wascomat also have multiple settings
Lifter Used as Sensors
• Two entire lifters used for sensing
• Lifters are isolated from cylinder
• Load provides conductance from lifter to tumbler
• Maintenance free
• ADC momentarily touches the load with one small set of
stationary contact strips
•Miele, Electrolux/ Wascomat use lifters
Rotational OPT Switch Assembly
• Receives constant signal from sensors and sends to micro
controller
• Rotational Switch life expectancy- billions of rotations
• Maintenance free
• ADC limited to testing a small sample of the entire load
• Miele, Electrolux/ Wascomat use external brush contactors
susceptible to wear and maintenance
