Why our Boot Dryers Work

Why It Works

Air Distribution	• Warmed air is mechanically distributed either to the farthest or hardest part of a garment (or boot, or glove, etc) to dry. • The air delivery system creates a positive pressure differential between the interior and exterior of the garment. • As the air exits the garment it passes over the interior surfaces picking up water vapor.
Air Temperature	• The temperature of the blown air is 10º-15ºF above room temperature. This temperature differential can generally only be physically perceived by touching a non heated portion of the machine (eg supports) then a heated piece ie support/air arm. • The purposes of using warmed air: - Warmed air holds more water vapor than cold. - Machine operating efficiency can be maintained even in conditions or reduced room temperature. • The benefits of using warmed air: - Drying tests verified the fact that even when a garment, boot, glove, etc felt dry there was actually a measurable amount of water still contained within the article. Water molecules are hydrotropically attached to the microscopic fabric fibres. Heat is required to excite the molecules enough to break this attraction. Complete drying within reasonable time periods can only be achieved with the addition of some heat. • Organisms such as yeast, fungus, & bacteria thrive in warm, moist, dark environments. The accumulation of this biological mass has potential health issues. The amount of this biological mass is subjectively measured by "locker room" odor. Eliminating the last of the moisture contained within the garment goes a long ways towards reducing the "locker room" indicator. • The 10º-15ºF temperature gradient is a subjective level which: - adds enough heat to provide significant drying characteristics especially at the final stages of drying. - keeps the delivered air temperature below body core temperature up to ambient room temperatures of 95ºF. - ensures that spot burning, heat deformation, or changing fabric characteristics (eg "thermo set glues ") is not a concern.
General Information	• All machines are 110V CSA approved for Canada & the USA which plug into any standard duplex outlet. • Construction is heavy duty with a limited life time warranty on superstructure and a 1 year warranty on electrical. • Finish is electrostatic powder coated white. • Duty cycle: machines can operate continuously. Our first dryer was built in 1989 and we have had machines operate for 15 years under industrial conditions. • Maintenance: keep the intake screen clean. A blocked screen reduces efficiency and decreases life expectancy.

"Drying time for different boot brands can vary up to 45 minutes under the same drying conditions"
