Industrial Petroleum & Oil Heaters: Engineered for Viscosity Control
Industrial Petroleum & Oil Heaters: Engineered for Viscosity Control
| Technical Specs | Range / Typical Values |
| Watt Density | 1.5–3.5W/cm2 (Very low) |
| Current | 5A – 100A |
| Connection | NPT Threaded or Flanged |
Low Watt Density Technology: By spreading heat over a larger surface area (typically 15–23 W/in²), we keep sheath temperatures below the oil’s “cracking” point, preventing fluid degradation and sludge buildup.
Rugged Steel & Incoloy® Construction: Elements are typically sheathed in heavy-wall steel or Incoloy® 800/840 to withstand the high pressures and corrosive sulfur compounds found in many petroleum products.
Explosion-Proof Reliability: For hazardous locations (Class I, Div 1 & 2), we provide NEMA 7 and NEMA 9 rated terminal enclosures to ensure safety in environments with volatile vapors.
Removable Element Designs: Our “Dry-Well” or “Pipe Insert” options allow heating elements to be replaced without draining the storage tank, significantly reducing maintenance costs and downtime.
| Feature | Light Oil / Lubricants | Heavy Crude / Bunker C |
| Sheath Material | Steel or Stainless Steel | Incoloy® or Carbon Steel |
| Watt Density | 20–25 W/in² | 8–15 W/in² (Very Low) |
| Max Process Temp | Up to 400°F (204°C) | Up to 650°F+ (343°C) |
| Mounting Types | Flanged, Screw Plug, Over-the-side | Large ANSI Flange / Manway |
Fuel Oil Pre-heating: Lowering the viscosity of heavy oils for efficient atomization in industrial burners and boilers.
Storage Tank Heating: Maintaining flowability in large-scale crude oil reservoirs and bitumen/asphalt tanks.
Lube Oil Consoles: Keeping turbine and compressor lubricants at optimal operating temperatures to prevent mechanical wear.
Heat Transfer Systems: Providing the primary heat source for closed-loop thermal oil systems used in chemical plants.
Offshore & Marine: Fuel and hydraulic oil heating for shipping vessels and oil platforms.
For critical industrial processes, a heating element is only as good as its durability and control. At Runkel, we specialize in high-spec thermal engineering. From high-vacuum environments to hazardous explosion-proof zones, we provide fully customized heaters integrated with bespoke Control Cabinets for a true “plug-and-play” experience.
The Total Solution: Integrated Control Cabinets. We don’t just provide the heat; we provide the brain. To ensure your heating system operates safely and accurately, we offer Custom-Built Control Cabinets tailored to your specific heater:Precise Control: PID or PLC-based systems for temperature accuracy within $\pm 1$°C.Safety First: Integrated over-temperature protection, leakage circuit breakers, and emergency stops.User Interface: Digital displays, HMI touchscreens, or remote monitoring capabilities.Custom Voltage: Built to match your local industrial power standards (e.g., 220V, 380V, 440V, or 480V).
“Complex Requirements, Simple Execution.”
Direct Replacement of Legacy Parts:
If your imported equipment has a failed flanged heater or a specialized vacuum element that is too expensive or slow to source from the OEM, we can reverse-engineer and manufacture a replacement that meets or exceeds the original specs.
Material Excellence:
We select materials based on your environment—whether it’s Incoloy 800 for high-temperature oxidation or Pure PTFE for chemical longevity.
