Considerations when selecting a hand dryer
The purchase of hand dryer should also pay attention to the hand dryer using the motor which is a form. Hand dryer with the motor has a variety of forms, there are capacitor asynchronous motor, shaded-pole motor, series excitation motor, DC motor, and permanent magnet motor, etc.. Capacitor asynchronous motor, shaded-pole motor, DC motor driven hand dryer has the advantage of low noise, the disadvantage is slow hand drying, high power consumption, and series excitation motor, and permanent magnet motor driven hand dryer has the advantages of large air volume, fast hand drying, low power consumption, and now the latest permanent magnet brushless DC motor combines the above features, low noise, large air volume, has become the best choice of hand dryer.
A, now dry hands fast, environmentally friendly and energy-saving hand dryer is wind-based, heating-assisted hand dryer. This kind of hand dryer is characterized by high wind speed, quickly blowing the water off the hands, while the heating function is just to keep the hands comfortable usually wind temperature between 35-40 degrees. In the fast dry hands at the same time, there will be no burning sensation.
Second, the main parameters of the hand dryer.
1, shell, shell material not only determines the appearance of the hand dryer, unqualified material may become a fire hazard, better hand dryer shell usually uses ABS flame retardant plastic, metal spray paint, and engineering plastic.
2, weight, mainly to consider the installation location and whether the material has sufficient capacity to withstand the weight of the hand dryer, for example, cement brick walls can generally not consider the weight problem, as long as the installation method is appropriate, this is not a problem, but if the color steel plate and other materials to consider the issue of load-bearing capacity, but some manufacturers of hand dryers provide brackets to solve such problems.
3, the color, the color is mainly a matter of personal preference and the overall environment with the problem, there is a food factory, pharmaceutical plants, etc. Try to choose the original color of the material hand dryer, because the spray paint hand dryer may have volatile, will affect the safety of food or medicine
4, start the way, usually manual, infrared induction two ways, now the new start photoelectric type, characterized by fast start, not easily affected by the environment, such as strong light may lead to infrared hand dryer keep turning or start their own, photoelectric using the amount of light into the way to start, thus preventing the problem of infrared hand dryer, the same does not need to hand contact dryer, thus preventing cross infection
5、Sensing location, you can choose according to their needs
6, the way of work, wall-mounted, bracket, according to their needs to choose, often move recommended the use of bracket type
7, the work noise, usually the smaller the better
8, dry hands time, the shorter the better
9, standby current, the better to adjust the better
10, wind temperature, according to their own needs and choose the type of hand dryer, usually choose a long time to run without burning sense is appropriate
