ceramic electric heater Advantage:
1.High quality,longer warranty time longer life time;
3.20% Higher efficience
The features of creamic heater
1 Electrical safety is good Has a very small leakage current (240V voltage, leakage current is less than 0.025mA); Even in the course of breaking occurs due to improper use, exposed electric wire cross-section will be immediately oxidized to form an insulating layer of protection without risk of electric shock (broken after the water leakage current is much less than the national standard value); electric strength, the 2500V high voltage for 60 seconds does not break down.
2. High surface heat load High strength and high thermal conductivity silicon nitride ceramic heating element that can with stand the show 80W/cm2 thermal load than traditional electric heating. Therefore, a silicon nitride same power electrical heating element size is about one third electrically heated metal pipe. 1500W heater heating zone just 7cm long.
3 Temperature uniformity As the heating element power density is high, small size, in the tank as point heat source, hot water tank can cause rapid convection, temperature uniformity, no dead water zone.
4.High thermal efficiency Silicon nitride ceramic thermal conductivity, electric wire heating energy can be quickly transmitted to the medium (water), low heat loss heating element itself, the heating efficiency than the metal tube heater about 20% higher
5.No scale The thermal expansion coefficient of silicon nitride ceramics is much lower than the scale, bonded to the scale on the heating element off by themself.
6 No Corrosion Silicon nitride ceramic itself can resist all kinds of acid corrosion, no protective coating and will never rust.
7 Intelligent temperature control Integrated imported thermostat, temperature control precision, strict control of water temperature,when the temperature get down then continue to heat up, that is safe and saving energy way .
8 Longer life As the installation of high-quality copper components, the use of high-temperature flame-retardant shell, so that the whole system is durable, maintenance-free life.
If you have requested the electric heater as 380V in 6000W/9000W/12000W,no problem,feel free to contact me!
