Steam hot air curtain air curtain is the electrical energy is converted into heat energy of high-power electrical equipment, because of its large heat and safe and reliable, wide use, has got the market favour. Hot air curtain is generally not equipped with air filter unit, because install air filter, increase the air intake resistance and reduce the number of inlet, also increased the load - heater (heater consists of a number of PTC ceramic composite) when the hot air curtain electricity that is, when the heater and fan work after work, after electrify PTC ceramic film rapidly warming, the wind of the fan out and now PTC ceramic high-temperature heat away on the surface, the lower the surface temperature of PTC ceramic chip.
Although hot air curtain is generally not add air filters, but there will be a lot of dust particles in the air, the particles will work with hot air curtain into the surface of the heater in the hot air curtain, air curtain use the longer, the dust particles in the air accumulated in the surface of the heater will be thick, it will affect the cooling speed of PTC ceramic chip cooling speed (heater), increases the overall temperature of the hot air curtain body, may also affect the stability of the fan, affect the service life of heater.
1. Can be divided by appearance
Large hot air curtain: mainly applicable to shopping malls and industrial and mining enterprises, large energy consumption of hot air curtain, FengMen effect is better
Small hot air curtain, installation height is not more than 3 m, the energy consumption of the air curtain is smaller
2. According to heat transfer can be divided into as well
Electricity hot air curtain, easy to use, no pollution, low cost of installation, the economy is applicable and the effect is good
Piping hot water hot air curtain: the system requirements such as water temperature is higher, the effect is generally
Steam hot air curtain, steam consumption is larger, restricted by the steam boiler, the best results
3. According to the direction can be divided into the air
On air supply hot air curtain (ld) : the wind from top to bottom, most hot air curtain is in this form
Side supply hot air curtain (side) : horizontal air supply, when installation height more than 5.5 m should be taken to this form
4. According to the use of motor can be divided into
Tubular hot air curtain, air volume is small, the installation height of 2.8 meters
Axial flow hot air curtain, air volume is small, the installation height of 3 meters
Centrifugal hot air curtain, air volume is bigger, according to the power of the motor to adjust the installation height, no more than 5.5 meters
