Sheath/Outer Material

Stainless Steel (SS 316/321), Incoloy, or Titanium for superior corrosion resistance

Voltage Rating

208 V – 240 V (single-phase); up to 600 V (three-phase) for large industrial systems

Power Rating

1 kW to 500 kW, scalable based on tank/vessel size and heating demands

Temperature Range

0°C to 250°C for water/oil heating; up to 600°C for high-temperature fluids/processes

Product Description

Corrosion from tough fluids and slow heating can lead to costly repairs and delays. That’s why our flanged heaters come with durable sheathing options like stainless steel or titanium, reaching 0°C to 250°C in 15-45 minutes. 

Heat-Up Time

15 to 45 minutes to reach target temperature, depending on power and liquid volume

Watt Density

5 W/in² to 80 W/in², customizable based on fluid type and heating requirements

Insulation Material

Magnesium Oxide (MgO) for high-temperature insulation and electrical safety

Corrosion Resistance

High resistance to water, oils, acids, and caustic solutions; material-specific options

Dimensions

Length – 300 mm to 3000 mm; Flange Diameter – 3″ to 24″ (customizable per vessel design)

Shape/Configuration

Multi-element U-shaped or straight tubular; designed for large-scale liquid immersion

Current-Carrying Capacity

10 A to 800 A, depending on power rating and conductor sizing

Heat Transfer Method

Direct conduction; efficient heat transfer to liquids via submerged elements

Mounting/Fitting Type

Flange (ANSI/ASME standards – 3″ to 24″); optional threaded adapters for smaller setups

Safety Features

Overheat protection (thermal cutoff), grounded sheath, and optional low-liquid cutoff

Standards Compliance

Meets or exceeds UL 1030, IEC 60335-1, EN 60519-1 (electric heating), EN 60204-1 (electrical safety), and ASME B31.3 standards

Technical Advantages

Industrial fluid heating puts heaters to the test with corrosive liquids and constant use. Our flanged heaters, built with power ratings from 1 kW to 500 kW, stand strong using materials that resist wear. 

Efficiency matters when heating large volumes. With a watt density of 5-80 W/in², these heaters transfer heat directly to fluids, working fast and saving energy.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How do your heaters stand up to corrosive fluids in big tanks?

Our heaters use tough materials like titanium or stainless steel that resist damage from acids, oils, and harsh chemicals. This strength keeps them working longer in demanding setups, giving sourcing teams a reliable option that cuts down on repairs and keeps production steady.

What makes flanged heaters a better fit for large systems than other types?

The flange design, with sizes from 3″ to 24″, handles higher power (up to 500 kW) and spreads heat evenly across big volumes, unlike smaller screw plug heaters. For procurement heads, this means a single, efficient solution for heavy-duty tanks, saving time and simplifying sourcing.

Can your heaters keep up with sudden production spikes?

Yes, with heat-up times of 15-45 minutes and power options from 1 kW to 500 kW, our heaters ramp up fast to meet unexpected demand. This flexibility helps purchasing managers ensure systems stay responsive, avoiding delays when output needs to jump quickly.

How do your heaters lower the risk of costly system failures?

They come with safety features like thermal cutoffs and optional low-liquid sensors, preventing overheating or dry-run damage in large tanks. This added protection reduces downtime and repair costs, offering sourcing professionals a dependable choice that keeps operations running smoothly. 

What’s the payback for choosing your heaters over cheaper models?

Our heaters last longer and perform better in tough conditions, cutting replacement and energy costs over time compared to low-cost alternatives. For procurement teams, this durability means a stronger return on investment, making your systems more competitive and cost-effective in the long run.
