PTC room warmer radiator heating element

PTC room warmer radiator heating element

1) Transflux type. tea infusion pot kettle warmer, auxiliary heating part, Water flows in the hole of the heating element and the water could be heated by the heating element.

2) Immerging type. hot warmer water bed, hot water heating systems. 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.

 5. Current products.

Some immerging heating elements.

 Stainless steel cylinder tube PTC heater

Titanium cylinder tube PTC heater

Notice:

1) PTC heating tube can be operated without water, at low water level, with incrustant depositing.
2) Applied voltage could be 12~72V, 100~600V. three phase voltage are possible.
3) The length of heating part could be selected between 50~800mm, 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,.

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.
