Product Details

PTC Hydropower Separation Heater A ceramic PTC thermistor yields a certain amount of free electrons that produce electrical conductivity by doping a material with a higher chemical value. The use of semiconductor hole principle, the realization of electronic oxygen vacancies to promote the collision of electrons in the field conditions, so that electrical energy into heat. 

Its characteristics are: 

◆ true separation of water and electricity: PTC heating film heating in the outer wall of the sink, the real separation of water and electricity. 

◆ High thermal efficiency: Because of the large contact area of the heater's heat transfer surface with water, water bubbles will not be generated on the contact surface (water bubbles will separate heat conduction), so the thermal efficiency is much higher than that of the electric heating tube; When only produce heat, there is no light consumption; and heating pipe heating wire in addition to generating heat, but also produce light-emitting light consumption. 

◆ Power self-adjusting: The heater power changes with the water temperature in the heater tank. If there is no water in the water tank, the heater will maintain the temperature at a constant temperature. At this time, there is no working current and no power. 

◆ long service life. 

◆ Heater performance parameters Operating voltage: 220V ~ 220V 3N ~ pressure 600-700V Rated frequency: 50Hz Pressure: 0.6MPa (water, air or other gases) Ground resistance: ≤ 0,1Ω Leakage current: 233VAC <0.75mA / kW (max ≤5 mA) Electrical strength: 1000V 1min Leakage current ≤30 mA Input power deviation: 20 ℃ Water temperature and flow 10L / min Power deviation ± 5% 1-20KW Heater size: 20KW or more can be customized according to user needs Multi-component (1-20KW heater) parallel installation. 

◆First, Comparison between "PTC" heater and heater heater:

 1, Electric heater 

1)the heating wire is installed in the metal pipe, insulated with electric wire and metal wall with insulating material for insulation , To prevent leakage, the charged metal inserted in the water heating. 

2) electric wire has light consumption, power consumption. Heating red to 500 ℃ ~ 1000 ℃ above heating, electric red, light consumption, heating as long as the heat consumption (such as electric light, lighting, light bulb heat is heat consumption), electric wire light consumption, with insulation Material Metal tube wrapped, no effect on liquid heating, wasted about 30% of the energy. 3) electric wire in the metal tube insulation material isolation, conduction to the outer wall of the metal tube to consume heat. Metal tube insulation wrapped heating wire heating, storage heating, heating wire easy to aging, fall off, after the break, it will break the insulation layer and the metal link leakage, there is electricity in the water, will cause a safety accident. 

4) heating wire heating not only power, but also noise (water sound), electric tube inserted in the water, high temperature water, tube wall produce a large number of bubbles, bubbles affect the heat conduction. Water storage heating is heat conduction induction heating, heating wire heater for a variety of reasons low effect.

 2, "PTC" hydropower separation heater: 

1) the use of efficient, energy saving, environmentally friendly new material "PTC" for heating. It has: no open flame, no light consumption, fast heating, low power consumption, high thermal efficiency, long life, safe and reliable, automatic control, constant temperature heating, easy installation and use. Is to eliminate electric wire, quartz tube replacement product. 

2) the "PTC" folder on the two "plate heat exchanger" between the "PTC" and water isolation, in the plate for the replacement of the hot plate in the liquid (water), the heater on the middle of the water pipe, one end into Cold water, the other end that is out of hot water. Is the thermal heating method, rather than water storage heating. 

3) heating wire in the 500 ℃ ~ 1000 ℃ fever, and "PTC" element maximum heating temperature within 250 ℃ low temperature heating, no light consumption, no open flame. Flammable liquid can be safely heated, gas stations, chemical research can be used. 

4) plate heat exchange. With low temperature heating plate change, under the conditions of low temperature water heating, no bubbles, no scaling. 

Second, "PTC" Introduction to the separation of water heater:

1, thermal materials (media): water, oil, alcohol, superconducting liquid. 

2, "PTC" water heaters separation purposes: instant electric water heaters, kitchen treasure, solar assisted heating, intelligent electric heating boilers, oil pipe heating, central air conditioning and electric auxiliary heating and train fuel, water, instrumentation insulation heating etc. 

Third, the "PTC" water heaters and electric heater wire heater data reference: 

1, the heater volume comparison: with the same 12KW two heaters confirmed (1) electric wire storage water heater: 100cm × 50cm × 50cm = 0.25cm3 (2) "PTC" is the thermal heater: 35cm × 12.5cm × 8cm = 0.0035cm32, the weight of the heater contrast (1) Electric wire storage water heater: weight 85 kg. (2) "PTC" Instant Heater: Weighing 2.8 kg. 3, Comparison of electric heating efficiency (1) electric wire storage water heater: less than 70% (with high temperature light heating) 500 ℃ ~ 1000 ℃ heating. (2) "PTC" Instant Heater: more than 98% (no light and low temperature heating) 250 ℃ heating. 4, Comparison of service life (1) Heating wire storage heater: 2000 ~ 3000 hours according to national standards (2) "PTC" Instant heating heater: 100,000 hours according to national standards 5, Heating time comparison Electric wire storage water heater: wait for 0.25 cubic meters of water after the use of heat (isolated conductive storage heater) (2) "PTC" Instant heater: wait for 0.0035 cubic water after the heat (PTC is hot The type of water is not water storage) without waiting for the instant heat. Summary: Practice has proved that "PTC" hydropower heaters can be done, electric wire heater does not do.
