Product Description

380V Stainless Steel Water Tank Heating Element Flange Heater for Industrial Boilers 

High-power DN40/DN50 Flange Heater has become the mainstream choice for 10-50m³ engineering water tanks with standardized interfaces and moderate power. Especially in scenarios where frequent start-stop or complex water quality is required, long-term stable operation can be ensured through material selection and safety protection design.

1. Basic parameters
- DN40/DN50: refers to the nominal diameter of the flange, the corresponding outer diameter is 48.3mm/60.3mm, and the diameter of the water tank opening is 50mm/65mm.
- Power range: single group DN40 flange electric heating tube (1-2 heating tubes) power 3-10kW, DN50 can integrate 2-4 tubes, power 5-15kW.
- Typical applications: 10-50m³ water tanks (such as temporary hot water tanks on construction sites, small fire water storage tanks). 
2. Installation process
- Water tank opening diameter = flange outer diameter + 2mm, edge polished smooth;
- Place a 3mm thick asbestos rubber pad between the flange and the water tank, and tighten the bolts three times in diagonal order (torque 40-60Nm);
- When wiring, ensure that the phase line and the neutral line do not touch the metal shell, and the grounding resistance is ≤4Ω.
