(1) Heater over-temperature control in electric heater is installed inside a high-precision thermal protection representative measurement points, steam hot water heater, the temperature measuring point the surface temperature of the heating element, hot water heater machine explosion , a PT100 temperature element thermal resistance, measured temperature signal by a temperature control instrumentation operation carried overtemperature control. Once the heating element overtemperature phenomenon occurs when electrical control immediately stops the power output of the electric heater, heating is stopped, this can effectively extend the life of the electrical heater. (2) the heating medium temperature controlled heater is installed in a high-precision temperature sensor, the internal temperature detection, temperature measurement element is PT100-proof thermal resistance, hot water heaters, the measured temperature signal is transmitted to the electrical control cabinet temperature control instruments, temperature-control instrument control operation adjust the output power of the electric heater, the heater outlet temperature reaches the user temperature requirements. Choice of standard air heater cleaner air heaters for summary presentation, we must be cleaned regularly, reason for this is because the deposition of air preheater in the course of the dust, air heater cooling effect also affect the heat pipe wall should be regularly cleaned. So what should be used in the washing detergent it? This work is essential for the cleaning of, let's look at specific: Usually we choose the air heater cleaning agent There are two main reference, respectively, because of its complex structure, so for precipitation emissions is very difficult , so we do not choose cleaner precipitation. Another is to take into account the material air heater, using hydrochloric acid as a cleaning agent, low temperature hot water heaters, corrosive, resulting in shortened life of the air heater, so choose the cleaning agent does not corrode. 4gs type hot water heaters machines, GS / Q type fan heater (online consultation), hot water heaters machine provided by the Texas Huaxin air-conditioning plant. Texas Watson conditioning plant (www.wchuaxin.com) (www.wchuaxin.com) Shandong Dezhou, heat, refrigeration and air conditioning equipment leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Air conditioning leader at Watson with the staff warmly welcome all inquiries negotiations to create Watson conditioned a better future.
