Water heating element
1) Transflux type. Water flows in the hole of the heating element and the water could be heated by the heating element.
2) Immerging type. The heating element is immerged in a water container, and the water could be heated by the heating element.
3) Underside type. The heating element can be put under a water container, and the water could be heated by the heating element.
4) Surrounding pipe type. The heating element can be surrounded out of the metal water pipe and the water in pipe could be heated.
The above types can be consist of materials below:
1) Aluminium
shell or pipe, it is not good in resistance to corrosion.
Anti-corrosion coating could be betterin
resistance to corrosion.
2)
Brass or
copper shell or pipe, it is good in resistance to corrosion.
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 shell or pipe, it’s very excellence for preventing
corrosion, and meets food safe standard. But it costs higher
and has bigger bulk.
5) Titanium shell, it’s very good in corrosion resistance, but the cost is quite high.
3. 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 wamer, 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.
4. Notice in appliance.
PTC as a heating element, it fits for high safety, long life-time, 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, 220~270Cswitch temperature PTC is selected usually. But if the switch temperature is too high, the reliable will reduce.

Notice:
1) Applied voltage could be 12~36V, 100~380V.
2) The length could be selected between some range, larger
power could be made with longer tube.
3) The fixing connected screw or flange could consist of brass,
aluminum or stainless steel. The shape could be selected by
customer.
4) The surface temperature without water, could be between
50~260C, the higher
is this temperature, the larger is the power.
5) For preventing corrosion, stainless steel shell, copper
shell, titanium shell, monel shell, could be selectted. The
surface can be nickel plating, paint anti-corrosion
coating.
