Produktparameter und Spezifikationen

Leistungsbereich:
Standard type: 5kW–30kW (small industrial water storage tanks, pipeline heating)
High power type: 30kW–100kW+ (large storage tanks, chemical reactors, continuous heating of food processing)
Working voltage: 220V/380V/440V three-phase AC (global power grid compatible, error ≤±5%).
Resistance value: 1Ω–50Ω (accurately matched by voltage and power, error ≤±3%).
Arbeitstemperatur:
Conventional model: continuous and stable operation of 60°C–150°C (self-limiting temperature design, anti-dry burning).
High temperature model: short-term tolerance of 250°C (customized Incoloy alloy heating wire + ceramic coating required).
Working pressure: normal pressure–10 bar (adapted to industrial pipeline pressurization system).
​​Material​​:
Heating element: either stainless steel 316L (enhanced corrosion resistance) or Incoloy 800/825 (resistant to high temperature oxidation and chloride ion corrosion).
Housing: rust-proof carbon steel galvanized or food grade 304 stainless steel.
Surface treatment: Teflon (PTFE) coating (anti-scaling, acid and alkali resistant) or aluminium ceramic layer (high temperature resistant up to 600°C).
Dimensions:
Heating tube length 1m–6m supports customized U-shaped, spiral, or straight tubes.
Suitable for DN25–DN200 industrial pipes, pipe diameter is Φ10mm–Φ50mm.
Service life, based on water quality and operating temperature, anti-corrosion coating extends life, ranges from 50,000 to 150,000 hours.
Customizable services: integrated temperature/flow sensor, support power, voltage, explosion-proof certification (Ex d IIB T4), IP protection level (such as IP68)

Wesentliche Vorteile

Effizientes Heizen und Energiesparen:
The thermal conductivity of the alloy heating wire is ≥180W/m·K, and the temperature rises to 150°C within 3 minutes, and the thermal efficiency is ≥98%.
Direct contact heating, no heat loss in the water storage tank, and energy consumption is reduced by 40% compared with traditional boilers.
​​ Corrosion resistance and long life:
Chloride ion corrosion resistance (suitable for seawater desalination and chemical condensate water heating), 316L stainless steel is resistant to pH 1–14 environment.
The surface Teflon coating resists scaling (anti-calcium and magnesium deposition efficiency ≥95%), reducing the cleaning frequency by 80%.
​​ Safe and reliable:

Automatic anti-dry burning protection: water level sensing + overheating power off (≥120°C automatic shutdown), in line with CE/UL/ATEX standards.
IP68 waterproof and dustproof (suitable for underwater installation) + explosion-proof design (chemical/petroleum scenarios).
​​Quick response and flexible adaptation:
Lightweight design (density 8g/cm³), supports fast start and stop with high temperature difference (cold start to 150°C in just 2 minutes).
Optional PID temperature control module (±1°C accuracy), suitable for constant temperature reactors and sterilization equipment.
​​Environmental protection and low maintenance:
Zero emissions, no noise, in compliance with the EU ErP energy efficiency directive (A+++ grade).
No moving parts design, maintenance-free cleaning (only regular inspection of coating integrity is required).
