2 MZF SERIES PTC Heating Elements

RoHS

A PTC thermistor is a thermally sensitive semiconductor resistor. Its resistance value rises sharply with increasing temperature after a defined temperature (Curie temperature) has been exceeded. This feature makes them ideal for use in countless applications of modern electrical and electronic engineering, for example as resettable fuses against current overload or as short-circuit protection in motors. You find special motor starter PTC themistors in the compressors of refrigerators for in- stance. Thermal protection of motors and transformers is another example of the versatility of PTC thermistors. The applications extend to measurement and control engineering, to household and automotive electronics, plus data systems and telecommunications of course. PTC thermistors are also suitable as self-regulating heating elements, in auxiliary heating, nozzle heating and carburetor preheating in automobiles, as well as in many domestic appliances such as door locks for washing machines, or glue guns and hair curlers. Due to the PTC thermistor is the more energy saving and safe component, it is widely used in many household electrical appliances, electric power facilities and electronic products. In general, application using PTC thermistor can be categorized according to three unique characteristics; resistance-temperature (R-T), current-time (I/T) and current-voltage (I/V) characteristic.

FEATURES AND APPLICATIONS

PTC ceramic thermistior is functional in stabilizing, adjusting and controlling temperatures Loaded by alternating or direct current, the temperature of PTC soars up with low resistance value. However, when it exceeds curie point, the resistance value arises suddenly and the current would drop to a certain value. Thus temperature is stabilized. For PTC thermistor, additional temperature-control devices are not necessary any more. Besides, different curie temperatures are realizable by adjusting the formula of PTC.

Inflammable & Reliable Compared with fuse, PTC components would not turn red nor on fire when heated. When the ambient temperature overpasses the limit, its power would drop to equilibrium value so as to avoid burning.

Long life length As oxide ceramic in nature, PTC neither oxidize upon high temperature as nichrome wire, nor as fragile as infrared lamps. It is kind of components with long life length

Wide Range of Voltage PTC components could work normally under either low voltage (3-36V) or high voltage (110-380V). - The low voltage PTC component could be applied in all type of low pressure heaters, low temperature compensation, vehicle heaters ect.. - The high voltage PTC is suitable for all electric devices such as shoes drying machine, glue gun, electric cooker, mosquito dispeller, venous transfusion heater, roller, vending machine, air cur- tain, hand warmer, etc.

ADVANTAGES

This kind of PTC water heater is used ceramic semiconductor - PTC heating elements as the main heating unit. There are many advantages as follows: a. PTC heating elements are not contact with water, which truly realized the separation between water and electricity. b. When power on it, the heater only fevers, no light, and not in danger of electric shock or open fire. c. Electrical insulation strength: 2000V/ ≤ 5mA/5s. No damage abnormal phenomenon after test. d. Long –time usage and stable heating capability. e. Good ability to resisting scale incrustation. f. Easily installation due to the small dimension

APPLIANCE

a. Electric cainuanlu heating hot water circulation b. Instant electric water heater c. High temperature cleaning machine d. Commercial plant f. Solar assisted heat

At present, our MZRD and MZRB series have been extensively applied in home air conditioner, commercial air condition as well as household heating appliance. The relations between power and wind speed, between power and ambient temperature as follows:

Standard test wind rate 4.5m/s, ambient temperature 25°C

DURABILITY OF PTC HEATERS (DECAY RATE)

Decay rate is used for evaluating the durance of PTC heaters. According to Industry Standard, the decay rate should ≤ 10% after working for 1000 hours. Here above is the decay rate chart of our standard Insulation PTC heaters.
