SRY8 Fin-type Electric Heater
Darui Electric recommends
This electric heater is used for heating hydraulic lubrication media, and for heating non-corrosive gases and liquids.
2. Features:
The finned tube sheathed electric heater consists of a "metal tubular electric heating element" and a finned protective sleeve. The finned protective sleeve is made of seamless steel pipe, metal fins, and asbestos rubber sealing gasket resistant to ≤300°C.
The electric heater is fixed to the oil tank body by flange connection; sealed by a gasket; the finned protective sleeve isolates the metal tubular electric heating element from the heated medium. When replacing the metal tubular electric heating element, it is not necessary to drain the oil from the tank; only the metal tubular electric heating element needs to be pulled out for replacement. It is convenient, reliable, and easy to use, maintain, and repair.
In this finned tube sheathed electric heater, the fins and the protective sleeve are assembled parts. Changing the number of fins can change the surface load of the electric heater. Proper use can prevent oil carbonization and burning, ensuring safety, reliability, and extending the life of the medium.

SRY8 Fin-type Heater
The fin-type electric heater can effectively increase the heat dissipation area, reduce the surface temperature, decrease the heater volume, and improve thermal efficiency.
The high-density electric heater is manufactured using special processes, which can greatly increase the surface load of the heater to meet different requirements. It is widely used for heating in spaces with limited size, such as molds.
1. High power, small size, fast heating.
2. Intelligent control mode, high temperature control accuracy, can be networked with computers.
3. Wide application range, long life, high reliability.
1. Heat treatment: Local or overall quenching, annealing, tempering, and through heating of various metals;
2. Hot forming: Whole piece forging, local forging, hot upsetting, hot rolling;
3. Welding: Brazing of various metal products
