Hand dryer technology increases usability, efficiency,
and sustainability of the modern restroom.
Many new hand dryers are automatic and touchless, activated by motion
sensors. Some are smaller
and able to meet ADA requirements without having to
 recess the hand
dryer into the wall. Other hand dyers can now automatically detect 110,
208, or 220 voltages, thereby adjusting itself to the appropriate
voltage and thus making it easier to replace an existing
installation. The construction of the dryers'
plastic covers are
made strong enough to support a full size truck and still run perfectly.
Adjustable variable speed motors allow the installer to determine noise
level vs. air speed. Low wattage environmentally friendly dryers without heating elements
dry hands
in 10 to 15 seconds.
Until recently, hand dryers
mounted on the wall about chest height, dry hands by blowing heated air
from one direction while the user moves and rubs hands together to
assist in the drying cycle. Now, there are dryers that utilize 300
separate nozzles to massage the water from the operator's hands at 125
mph without the use of hand
 movement. These new hand dryers work by
the user placing their hands
into the dryer and holding them still until the end of the cycle.
The plastic used for the interior of these units are imbedded with Microban®, an antimicrobial agent which protects the product itself. Using this type of dryer will feel like a
massage to the hands. The unit mounts upright on the wall, just
below waist level, and dries hands in 10
to 15 seconds while using 80% less energy than conventional hand dryers.
Conventional hand dryers use up to 2200 watts of power for 30 to 45
seconds. These new dryers use less than 1800 watts of power for as
little as 10 seconds. Because the dryer runs for less time and
uses less power, energy is saved each time the dryer is used.
Additionally, excess water is captured
inside the unit and evaporates naturally keeping water from being
dripped onto the floor. These hand dryers combine the best
technologies with elegance and efficiency.
 Hand dryer technology has been used
to create a dryer that uses only 540 watts of power and will dry your
hands in less than 15 seconds. To achieve the low wattage usage,
the dryer uses only the heat from the blower motor, so it has no heating
element. Not only does this technology save resources but it
reduces installation cost and allows the dryer to be installed in places
that it could not be installed because of the wattage usage. The
low wattage allows up to 3 of these dryers to be installed on one
circuit. This reduces installation time (most electricians charge
by the hour) and can cut the number of new circuits needed by 1/3.
In some cases, normal wattage hand dryers could not be installed because
of a lack of power in the building. This dryer uses only 540 watts
so it can be install on an existing circuit with other devices as long
as the total power usage does not exceed the allowable power of that
circuit (check with your electrician for details).
