With 20 years experience, Hongtai Alloy is your trusted source for quality electric industrial flanged immersion heaters as one of the leading suppliers of various heaters in China. Providing you with the most competitive price, we welcome you to buy the heater from our factory.
Stop Settling for Weak, Unreliable Tank Heating
When you're dealing with large industrial tanks-chemical vats, oil reservoirs, boiler systems-you need a heater that's built to pull its weight. Our Hongtai Electric Industrial Flanged Immersion Heater is that workhorse. Designed to mount directly to tank flanges (no messy retrofits), it dives right into liquids and cranks out consistent, high-volume heat-no power dips, no premature failures.
Crafted with a high-purity nickel-chromium (NiCr) heating core (90% Ni/10% Cr) and 304/316 stainless steel sheath, this heater laughs off harsh conditions. Corrosive chemicals? High-pressure tanks? Vibration from industrial pumps? It handles it all. Heat-up is fast, even for 1000+ liter tanks, and it runs steady for 5000+ hours-way longer than the flimsy flanged heaters that conk out when you're in the middle of a production run.
We've got options for every setup: flange sizes from 2" to 12", power ranges from 100W to 20kW, and voltage compatibility for global markets (110V US, 220V EU, 380V three-phase industrial). Whether you're heating oil for a manufacturing line, maintaining temp in a chemical reactor, or boiling water for a boiler, this heater delivers the muscle you need.

Why It Outperforms Generic Flanged Heaters
1. Built for Heavy-Duty Industrial Use
Generic flanged heaters use thin sheaths and low-grade heating cores-they burn out in 800-1200 hours, even in mild conditions.Ours? 304/316 SS sheath (thickness 1.5mm) resists corrosion and impact. A chemical plant in Texas uses the 316 SS model to heat 10% sulfuric acid-runs 24/7 for 18 months straight, no issues. Their old heaters died every 3 months.
2. No Cold Spots – Uniform Heating for Large Tanks
Trying to heat a 5000L tank with a weak heater leads to uneven temp-ruining chemicals, thickening oil, or wasting energy.Our multi-tube design (3-12 heating tubes per flange) spreads heat evenly across the tank. A biodiesel plant in Iowa uses our 60kW model for 2000L oil tanks-temp stays within ±2°C from top to bottom, cutting fuel waste by 12%.
3. Easy Installation, No Production Downtime
Mounting a flanged heater shouldn't require shutting down your line for a full day.Ours fits standard ANSI/DIN/JIS flanges-bolt it on, wire it up, and you're good to go. A manufacturing plant in Ohio swapped out their old heater for ours in 45 minutes-no professional installer needed.
Where It Works (Industrial-Grade Applications)
Chemical Industry: Heats acid/alkali tanks, reaction vessels, solvent reservoirs. Texas plant runs 316 SS model for 10% sulfuric acid-18 months of non-stop use.
Oil & Gas: Maintains temp in crude oil tanks, lubricant reservoirs, biodiesel processing. Iowa biodiesel plant cut fuel waste by 12% with even heating.
Food & Beverage: FDA-approved models for syrup tanks, brewing vats, dairy pasteurization. Wisconsin dairy uses it to heat milk to 72°C (pasteurization temp)-meets USDA standards.
Power Generation: Boiler water heating, condensate tanks. A power plant in Pennsylvania uses 120kW 380V models-fast heat-up cuts boiler startup time by 40%.
Manufacturing: Heat treatment tanks, plating baths, plastic molding resin heating. Ohio factory reduced installation time to 45 minutes.
How to Pick the Right One
Tell us 5 quick details-we'll get you the perfect fit:
Tank Specs: Volume (L/Gal), material (stainless steel/plastic), and flange size/standard (ANSI/DIN/JIS).
Heating Medium: What you're heating (acid/alkali, oil, water, food products) – we'll recommend the right sheath material.
Voltage/Power: Local power supply (110V/220V/380V) and required power (or tell us tank volume + target temp-we'll calculate it).
Working Conditions: Pressure (bar), max temp, and any special needs (corrosion resistance, explosion-proof).
Installation Preferences: Number of heating tubes, lead wire length, or additional controls (thermostat, level switch).
Quality & Support You Can Count On
Every Hongtai Electric Industrial Flanged Immersion Heater goes through 7 strict quality checks: core resistance testing, sheath thickness measurement, insulation testing, pressure testing, and a 2-hour full-power heat test. No duds leave our factory.

Absolutely-we offer high-pressure models (up to 25 bar) with reinforced flanges and sealed sheaths. Just let us know your pressure rating when inquiring.
Q: Do you offer explosion-proof models?
Yes-for flammable liquids (oil, solvents), we have explosion-proof (Ex d IIC T4) models that meet ATEX and UL standards. Perfect for oil refineries or chemical plants with hazardous zones.
Q: Sample available for testing?
Yep-1 piece minimum. Sample cost is 1.5x wholesale (e.g., $250 for a 10kW 220V model), fully refundable on bulk orders (50+ pieces). Ships via DHL/FedEx-7-10 days to US/EU addresses.
Q: Can you customize the flange to fit our non-standard tank?
No problem-we make custom flanges to match DIN, JIS, or your unique tank specs. Just send us your flange drawing, and we'll build it to fit.
