Explosion-proof Electric Heater
It is composed of bent tubular elements welded to a flange. Because the tubular electric heater is directly heated in oil, it has high thermal efficiency and long service life. Among them, 1KW to 4KW work in an environment around 300°C, and 5KW to 8KW are suitable for environments around 100°C.

HRY14 tubular electric heater is based on SRY2 ordinary tubular electric heater, improving its wiring device and heating structure. It uses three heating tubes as a group, effectively reducing the surface load of the heater, and can directly replace SRY2-SRY4 heaters.
Sheath-type electric heater Instructions:
1. The working voltage must not exceed 1.1 times its rated value, and the shell should be effectively grounded.
2. Dimension "B" in the figure must be fully immersed in oil (and checked regularly) to avoid burning. The heated oil should have no corrosive gas.
3. The mounting hole size of the tubular electric heater is φ65mm.
4. This model of tubular electric heater is designed according to JB2379-78 flowing oil standard, with a heater surface load of 2-3.8 w/cm2.
5. When selecting, determine the heater size according to the actual size of the heating medium.
Note: The tubular electric heater can be directly mixed with SRY2 and SRY4 types.
