Product Description

Heating fluids without a fixed setup can be tricky such as corrosion, slow warm-up, or awkward designs often mean extra costs and hassle. Our portable heaters solve this with tough sheathing like stainless steel or Teflon-coated options, warming up from 0°C to 150°C in just 5-20 minutes. 

Heat-Up Time

5 to 20 minutes to reach target temperature, depending on power and liquid volume

Watt Density

5 W/in² to 40 W/in², customizable based on fluid type and safety requirements

Insulation Material

Magnesium Oxide (MgO) or Silicone Rubber for insulation and electrical safety

Corrosion Resistance

High resistance to water, oils, mild acids, and alkalis; material-specific options

Dimensions

Length – 200 mm to 1200 mm; Width – 50 mm to 300 mm (customizable per tank depth/width)

Shape/Configuration

L-shaped, straight, or coiled tubular; designed for over-the-side immersion

Current-Carrying Capacity

2 A to 100 A, depending on power rating and conductor sizing

Heat Transfer Method

Direct conduction; efficient heat transfer to liquids via portable immersion

Mounting/Fitting Type

Over-the-side hook, clamp, or bracket; portable, no permanent installation required

Safety Features

Overheat protection (thermal cutoff), grounded sheath, and optional moisture-resistant housing

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

Temporary setups shouldn’t mean weak performance. Our portable heaters, with power ratings from 250 W to 25 kW, use durable materials that resist corrosion from tough liquids. This reliability cuts down on replacements, offering sourcing professionals an affordable option that keeps working through multiple jobs without breaking the budget.
You need heat that’s fast and fits the task. These heaters deliver direct warmth with a watt density of 5-40 W/in², heating liquids efficiently in portable setups.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How easy is it to move your heaters between different tanks?

Our heaters come with a lightweight, over-the-side design using hooks or clamps, so you can lift them out and set them up in another tank in minutes. This portability saves sourcing teams time and effort, making it simple to shift heating from one job to the next without extra tools or setup costs.

What’s the cost benefit of using your portable heaters instead of fixed ones?

Unlike fixed heaters that need permanent installation, our portable models cut installation expenses and work across multiple tanks, reducing the need for extra units. For procurement heads, this flexibility lowers upfront costs and stretches your budget further, especially for temporary or varied projects.

Can your heaters handle heating thicker liquids like oils or syrups?

Yes, with power options up to 25 kW and a watt density of 5-40 W/in², our heaters warm viscous fluids like oils or syrups efficiently, avoiding hot spots. This capability gives a versatile solution that keeps processes smooth, even with challenging liquids. 

How do your heaters hold up during transport or rough handling?

Built with sturdy sheathing like stainless steel or Teflon-coated materials, our heaters resist bumps and wear from moving between sites or jobs. This toughness means fewer repairs for sourcing professionals, keeping your portable heating reliable no matter where it’s used.

What’s the advantage of buying your heaters for short-term rental clients?

Their quick setup and power range from 250 W to 25 kW make them ideal for rental markets, offering fast, dependable heat that clients can use right away. This versatility boosts your product’s appeal, helping win business from customers needing temporary heating solutions.
