The error of selecting heating coils:

1; the bigger power the better: heater heating wire resistance is based on the selection of power, the bigger the power, the total resistance is smaller. The resistivity of the heating wire has a proper range, if the resistance is too large or too small, it needs short or long, thin or thick electric wire, it will be causing difficulties of heating appliance’s manufacturer and using. Electric wire is an important parameter. Resistivity is too large will leads to larger power when provided current. Therefore, low-power appliances had better choose small current, but the current magnitude decides resistive data.

Meanwhile, in order to ensure bigger power, it must have a sufficiently large current, so the surface area of the power in certain circumstances, there is a limit! Production quality super power heater is unwarrantable.

2 the thinner the better. Some customers in the selection of the heater are preferred thin shape, and as a sign of strength judge manufacturers. In fact, if life was not required the thickness of only 0.5 is possible, just a little bit complicated process.

3 color judgments

Some of European suppliers’ heater surface is green, as well as some domestic production of heaters are with high brightness. In fact, these are the surface treatment of the relationship, even less jerry tempering processes.

4 the softer the better: soft heater surface using a special metal, such as copper, in addition, to all the technology and other armored heaters work is the same. The copper from the quantitative abroad requires a great deal every time, while the total market demand for flexible heater manufacturers generally not large, so suppliers are reluctant to produce.

the standard of Judging heater quality:

1. Heating uniformity, long life.

2. Seismic and corrosion resisting

3. Good pressure resistance
