SRQ3 Air Heater Detailed Information:
I. SRQ3 Air Heater Application:
SRQ type tubular electric heating elements are used in the air ducts of air heating systems for blowing hot air, and can also be used as heating elements for various ovens, paint drying, and electric furnaces.
II. Specifications and Technical Data:
1. Specifications and Dimensions: See Table 1 and Figures 1-5
2. Working voltage tolerance: not greater than 1.1 times its rated value. The casing should be effectively grounded.
3. Working environment: relative humidity not greater than 95%, free from explosive, flammable, and corrosive gases.
4. Metal tube material: No. 10 steel or stainless steel.
5. Maximum working temperature: 300°C
6. Fastener: M22×1.5, length 45 mm.
III. Usage, Maintenance, and Precautions:
1. Components are generally arranged in a staggered pattern in the duct, with a relative distance between two components greater than 40 mm to ensure full heating of the flowing air. The duct should be insulated around to reduce heat loss. The air velocity in the duct is generally suitable at 8-12 m/s.
2. The terminals of the components should be installed outside the insulation layer. The effective heating part should not be covered with insulation to avoid burning the components.
3. Components should be stored in a dry place. If the insulation resistance drops below 1 megohm due to long-term storage, it can be restored by drying in an oven at about 200°C for several hours (or by applying low voltage to the components for several hours).
