SRY6-3 380v/3kw Sheathed Electric Heater
SRY6-3 380v/3kw Sheathed Electric Heater, it has a large heat dissipation area and fast heat transfer. The terminal device part is divided into ordinary type (using iron-made stretched cup-shaped housing) and special type (using bolted explosion-proof housing seal), the special type meets the requirements of explosion-proof mark dllCT4 and protection level IP65 series standards.
It consists of a heating core and a sheath. The heating core uses high-temperature resistant alloy electric heating wire as the heat source, high-temperature resistant ceramic as the insulating medium, and the sheath is made of cold-drawn seamless steel pipe or stainless steel.

Troubleshooting and Maintenance:
1. Heating power too low, heating temperature too low:
(1) Check the heating element and circuit
(2) Check the function and setting of the temperature controller
(3) Clean the heating element group
2. Heating power normal, heating temperature too high:
(1) Check the function and setting of the temperature controller
3. Low insulation resistance of heater to ground
(1) Check if there is any debris in the wiring device
(2) Check if the heater is damp
(3) Check if the cable has any damage
5. Replace the heating element
1. Cut off the power supply
2. Depressurize the heater
3. Disassemble the heating element group;
4. Loosen the nut and pull out the heating element;
5. Install the new heating element in reverse order
