HRY6 sheathed electric heater

HRY6 sheathed electric heater Introduction:

1. It adopts the form of multiple U-shaped electric heating elements with multiple special-shaped sheaths, which has a large heat dissipation area, fast heat transfer, and long service life. Features such as easy replacement and maintenance.
2. Due to the use of multiple U-shaped electric heating elements with multiple special-shaped sheaths, if one electric heating element is damaged, only the damaged element needs to be replaced without replacing the entire heating source, greatly reducing the subsequent investment of the user.
3. The surface load design can be determined according to customer needs, with a standard surface load design of 0.7 watts per square centimeter.
4. The sheathed tubular electric heater can be equipped with liquid expansion temperature controller, manual reset, AC contactor and other electrical equipment. If the heater needs to have temperature control function, only the temperature control device needs to be installed. When customers order, add the letter "T" after the model number; If automatic constant temperature function is required, the heater should be equipped with a temperature controller and contactor, and the letter "TH" should be added after the model when ordering.
5. Allowable error of working voltage: not greater than 1.1 times its rated value. The casing should be grounded.
6. Working environment: The relative humidity should not exceed 95%, and there should be no explosive, flammable, or corrosive gases.
7. Heater material: carbon steel or stainless steel.
8. Maximum working temperature: 200 ℃.
9. Work pressure: less than 0.6MPa

10. Specifications and external dimensions: see the table and attached drawings on the next page
HRY6 sheathed electric heater Main technical parameters:
Rated voltage: single-phase 220V, three-phase 380V
Surface heating power: Type 4, Type 5 ≤ 1.8W/cm2, Type 6, Type 7 ≤ 0.7W/cm2
Heat transfer temperature: ≤ 300 ℃
Working medium: Mineral oil
Work pressure: ≤ 0.8Mpa
Heater installation hole: ≥ φ 114mm
Note: When selecting, the surface heating power should be selected as much as possible based on the actual situation of the heating medium and the installation size of the equipment, with a surface heating power of ≤ 0.7W per square centimeter. When wiring, suitable high-temperature wires should be used to connect the distribution control box to the electric heater.

Set behind the water blocking plate in the spray room. Although preheaters and reheaters are both used to heat air, their functions are not exactly the same. They cannot be confused or replaced, otherwise the air state in the workshop will change. Product features: Small size, high power. The heater mainly uses bundled tubular heating elements inside, with each bundled tubular electric heating element having a maximum power of KW. It has fast thermal response, high temperature control accuracy, and high comprehensive thermal efficiency. Wide application range and strong adaptability. This heater is suitable for explosion-proof or ordinary occasions. Its explosion-proof rating can reach Class B and C for men, and its pressure resistance can reach Mpa. The cylinder can be installed vertically or horizontally according to user needs. The heating temperature is high. The maximum operating temperature of the heater design can reach ℃, which is not achievable with typical heat exchangers. Fully automated control. Through the design of this heater circuit, automatic control of parameters such as outlet temperature, pressure, and flow rate can be easily achieved, and it can be connected to a computer for human-machine dialogue.
