Humidity Sensing Saves Time, Energy, and Money in Your Commercial Laundry

Humidity Sensing Saves Time, Energy, and Money

B&C Technologies Humidity Sensor

We all know that tumble dryers aren’t particularly gentle, but along with the tumbling action, there are other dangers lurking in the dryer. Over drying can damage or shrink fabrics, and a moisture sensor minimizes that possibility. Commercial Laundry dryers equipped with a moisture sensor can save up to 15% on energy costs over standard timed drying by measuring the remaining water left in the goods, and stopping the drying process when they are dry.

There are quite a few worthwhile benefits of moisture sensing:

  • Less wear and tear on goods
  • Lower energy costs
  • More loads per week
  • Automatically adjusts to different sized loads
  • Automatically adjusts for different fabric types
  • Excellent for special processes like wet cleaning

Humidity sensing allows for a gentler drying process, as heat damage to the goods mainly occurs after the water has been removed from the goods via evaporation. As the dryer adds heat, the energy is used to heat the goods and the water in the goods to the point where the water vaporizes. Water has a very high latent heat, meaning it takes quite a bit of energy to change it from a liquid to a gas. In a dryer, this energy is supplied by the fuel type (gas, steam, or electric heating) and typically heats the airstream much higher than the boiling point of water (212F or 100C). However, the water contained by the goods can only be heated to its boiling point so the maximum temperature the goods see is 212F or 100C. After the water is removed, the goods will be able to absorb the full amount of heat from the air stream and this is what causes fabric damage, wastes energy, and wastes time, leading to lost profits.

Humidity sensing is another fantastic tool in an efficient commercial or industrial laundry that is critical for utility savings as well as adding life expectancy to the laundered items and should be insisted upon for any dryer purchase.
