Vapor generator

Use:

Vapor generator is used to boil water and evaporate from liquid to gas state. The steam can add humidity in air, add water on face, sterilize the cooking appliance, or for sauna purpose.

Classify:

1.Classify by heating elements.

Type	Specialty	Excellence	shortcoming	Others
PTC self- controlled heater	The temperature can be limited by PTC itself, preventing over temperature.	Long life, safety simple structure, temperature protector are needless	Lower power	Used in small power heater
Casting Al heating plate	Cast the heating wire in aluminum plate	Large power and evaporate quickly	electricity is inhibitive without water, need protector, high cost	Used in large power heater
Ultra-sonic humidifier	Ultra-sonic smash water into fog	Fog effect can be seen, save energy	Short life, no warm, impurity and granule in water disperse into air, high cost	Used in humidifier only

2.Classify by structure for PTC heating.

Type	Specialty	Excellence	Shortcoming	Others
Transflux heater	Water flow in the enter of the heater and vapor come out in exit	Large power, evaporate water quickly, high efficiency	Complex structure, pump may be needed.	It can be linked to tap water supply
Bottom heater	Heater is put at bottom of tank	Simple structure, low cost, easy to clean	Low power, low energy efficiency, long waiting time to heat all water to boil point	Used in small power only
Immerging heater	Heater immerge at bottom of water	It can be used to evaporate quiet water, high efficiency	long waiting time to heat all water to boil point

Notice for manufacturer and consumer:

      The power of PTC is very different from applied conditions.
      To shorten the waiting time of initial vapor, add little water in the pot first. After vapor, add other water at the same time as vapor.
      Neglecting other energy consume, vaporizing 1 gram water need 2260 J of heat energy. If vaporizing 1 gram water in one second, it generate 1.3 liter steam, 2260W of power is needed.
Power is 10% smaller on 110V than on 220V for the same PTC heater.

PTC self-controlled heater:

Our company can supply PTC heater with shell, transflux type, immerging type, or Bottom type. Various coating, such as Teflon, ceramic paint, or oxygenation on surface of shell is possible. We also supply PTC heater with insulating film, or PTC heating pellet. But for getting high power, PTC heater with shell is commended firstly. Electric power of one part is between 100~500W, and parallel several parts can be used for larger power.
