Industrial Boilers: Steam generation, hot water storage, and closed-loop boiler systems.
Petrochemical & Oil: Pre-heating fuel oils, storage tanks, and viscosity control for heavy lubricants.
Chemical Processing: Heating corrosive solutions, detergents, and alkaline baths.
Clean Energy: Heat transfer for thermal energy storage and hydrogen production processes.
Food & Beverage: CIP (Clean-in-Place) systems and large-scale pasteurization.
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.
