When buying hand dryers, consumers should decide which hand dryers to buy according to their own needs and the environment. PTC type hand dryer, because with the change of environmental temperature, the PTC heating power also changes, in the winter, the PTC heating power increases, the hand dryer blowing out of the warm air temperature rise also increases. The electric wire hand dryer is simple and practical with long service life. Consumers can also according to their own needs, choose to wind as the main heat auxiliary air volume hand dryer, or heat based hot air hand dryer. In the selection of electromagnetic induction hand dryer, should pay attention to the hand dryer easily affected by the environment, items. Choose infrared induction hand dryer to pay attention to, infrared induction hand dryer is also easy to be interfered by light, consumers in the purchase of time to test the machine, choose not easily interfered hand dryer. When buying hand dryers, you should also pay attention to the form of electric motors used in hand dryers. There are many kinds of motors for hand dryers, such as capacitor induction motors, hood motors, series motors, direct current motors, and permanent magnet motors. Capacitor asynchronous motor and cover pole motor, dc motor driven hand dryer has the advantages of low noise and series motor and permanent magnet motor driven hand dryer has the advantages of big air volume, now the latest brushless dc motor is a combination of the above characteristics, low noise, big air volume, now became the best choice for hand dryer.

First, now fast hand dryer, environmental protection and energy saving hand dryer is mainly wind, heating auxiliary hand dryer. This hand dryer is characterized by high wind speed, which will blow the water out of the hand quickly, while the heating function just keeps the comfort of the hand. The wind temperature is usually between 35-40 degrees. Dry your hands quickly without burning them.

Ii. Main parameters of hand dryer:

1. Shell: The shell material not only determines the appearance of the hand dryer, but unqualified material may become a fire hazard. The better shell of the hand dryer usually adopts ABS flame retardant plastic, metal spray painting and engineering plastic.

2, weight, main is to consider the installation location and materials have the ability to bear the weight of the hand dryer, such as: concrete block wall generally can not consider the weight problem, as long as the installation method right, this is not the problem, but if is about to consider choi steel materials such as bearing capacity, but some manufacturers hand dryer to provide support to solve this problem.

3, color, color is mainly personal preferences and the overall environment of the problem, there are food factories, pharmaceutical factories and other materials to choose the primary color of the hand dryer, because the spray paint hand dryer may be volatile, will affect the safety of food or drugs

4, startup mode, usually for manual, two methods of infrared sensor, photoelectric type, now new startup mode is characterized by fast start, is not susceptible to environmental effects, such as strong light may lead to keep running hand dryer or start, infrared photoelectric adopt the way of keep out into the light, so as to prevent the problem of infrared hand dryer, also don't touch your hand dryer, so as to prevent the cross infection.

5. Induction position can be selected according to your own needs

6. The working mode, hanging on the wall and bracket, should be selected according to their own needs. It is suggested to use the bracket type when moving frequently

7. The less noise you make at work, the better

8, dry hand time, the shorter the better

9. Standby current, off-modulation is better

10, wind temperature, according to their needs and choose the type of hand dryer, usually choose a long time operation without burning feeling is appropriate

Iii. Purchasing Suggestions:

When buying hand dryers, don't just look at the price of the hand dryers themselves. Although some hand dryers are very cheap in price, they are like tigers when using electricity, which can hardly control the consumption of electricity. Therefore, we should try to buy products with low energy consumption. Low energy consumption is characterized by short drying time and relatively low power, so it can be calculated as follows: energy consumption = power * time. There are as far as possible to see the product, after trying to buy, now a lot of small hand dryers manufacturers use inferior materials made of hand dryers, continuous use of a long time after the deformation of the shell, there are serious fire hazards.
