Air electric heater is heat exchange equipment using is converted into heat energy, with the advantages of convenient energy supply, compact structure, automatic temperature control, easy installation and maintenance, no pollution, etc. The electric heater is composed of tubular container and electric heating element, with temperature control cabinet (table). The control part adopts advanced digital circuit, integrated circuit flip-flop, high-reverse voltage SCR and other components of adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater. The heating element adopts straight tube type instead of U-shaped structure, and the special sheet metal hand can be easily installed and disassembled. The temperature control adopts silicon control, PID digital display, in the temperature control range, can set the required temperature, and automatically maintain constant temperature, control temperature ± 5 ℃. And there are sound and light alarms and a number of protection functions, and can be controlled locally or from a distance. Special requirements can also be designed and manufactured on behalf of the.
The finned tubular heater is a kind of heat exchanger tube to improve the heat exchange efficiency, usually by adding fins on the surface of the heat exchanger tube to increase the external surface area (or internal surface area) of the heat exchanger tube, so as to achieve the purpose of improving the heat exchange efficiency. As a heat exchange element, the finned tube works under high temperature flue gas conditions for a long time, such as boiler heat exchanger with finned tube using a harsh environment, high temperature and high pressure and in a corrosive atmosphere, which requires the finned tube should have a high performance index.
