But it costs higher. 3) Ceramic shell, it’s good in resistance to corrosion. But its heating power could not be very large. 4) Stainless steel or titanium shell or pipe, it is very excellence for preventing corrosion, and meets food safe standard. But it costs higher and has bigger bulk. China patent number: ZL 2011 2022 0811.4, ZL 2011 2022 0805.9.5) Anti-corrosion coated aluminum shell, it is corrosion resistance, and prevent incrustant, but the cost is quite high.2. Some samples of uses.PTC water heater could be used for shower, footbath, washing hand, vegetable and dish, drink warmer and boiler, fermenter, tea warmer, coffee warmer, milk warmer, vapor generator, sauna bath.They could be used in heating diesel oil, gasoline or other liquid. Using PTC as a heating element could prevent the oil burning, it’s safer.3. Notice in appliance.PTC as a heating element, it fits for high safety, slap-up product. In some situations, it’s low cost and convenient.The electric power of PTC water heater changes with the temperature of water. The higher is the temperature of water, the smaller is the power. Using higher switch temperature PTC can get higher power, 220~270℃switch temperature PTC is selected usually. But if select too high switch temperature, the reliable will reduce. Power is almost same to change the voltage twice or decrease of 1/2. 4.

Two applied voltages in one heater; three phase voltage are possible.3) The length of heating part could be selected between 50~800mm, the longer is the shell, the larger is the power. 4) The connected screw or flange could be customer made.5) The surface temperature without water, could be between 50~260℃, the higher is this temperature, the larger is the heating power.6) The stable temperature of water would be affected by the heating power, cubage of water, the shape and material of container, heating dispersion, evaporating of water, temperature controller.7) The tube can be consist of aluminum, copper, brass, 304/316/316L stainless steel, titanium, monel alloy. The life time for aluminum tube is around 2years, for stainless steel is around 5years continuously operation.8) For preventing corrosion, the surface of tube can be coated with Teflon, used for heating element in electroplate tank is possible. 9) A thermostat or thermo-couple or sensor can be assembled in the tube for controlling the temperature of water.10)TUV approval number: B 09 06 46746 004,B 09 08 16746 008.11) National patent, ZL 2010 2 01356626.0, high power density water heater. National patent, ZL 201320630141.2, surround PTC heating tube.National patent, ZL 2011 2022 0811.4, anti-corrosion PTC heating tube. National patent, ZL 2011 2012 6016.9, Used for special high security, there are 2 layers of insulator and 2 layers of metal protective layer.
