I. Purpose:
SRY7 straight rod tubular electric heating element is suitable for heating oil in enclosed oil tanks.
II. Features:
Based on the SRY2 ordinary tubular electric heater, its wiring device and heating structure have been improved. Three heating tubes are used as a group, effectively reducing the surface load of the heater. It can directly replace the SRY2-SRY4 type heater.
SRY7 straight rod tubular electric heating element is formed by welding bent tubular elements onto a flange. Since the heater is directly placed in the oil for heating, it has high thermal efficiency and long service life.
III. Main Technical Parameters, Specifications, Length:
Rated Voltage: Single-phase 220V Three-phase 380V
Working Medium: Mineral oil, water, and other media with good heat dissipation effect
Surface Heating Power: 1KW～4KW 1.5w/cm2 5KW～8KW 2.5w/cm2
Working Pressure: 0.6Mpa
IV. Instructions:
1) The working voltage must not exceed 1.1 times its rated value, and the housing should be effectively grounded.
2) Dimension "B" in the diagram must be fully immersed in oil (and checked regularly) to avoid burning. The heated oil should be free of corrosive gases.
3) The mounting hole size for this electric heater is φ65mm.
4) This model heater is designed according to JB2379-78 flowing oil standard, with a surface load of 2-3.8 w/cm2.
5) When selecting, the heater size should be determined based on the actual dimensions of the heating medium.
