SureHeat Max vs. Threaded Inline: Which Heater is Right for You?

Choosing the right industrial air heater is critical for optimizing efficiency and meeting the demands of your specific application. Two popular options from TUTCO SureHeat—the Max Air Heater and the Threaded Inline Heater—offer reliable performance but are suited to different needs. Both heaters are UL, CE, and RoHS compliant and can reach exhaust temperatures of up to 1400°F. However, they differ in pressure capacities, temperature tolerances, and design features, making it essential to understand how these differences apply to your project.

The Max Air Heater is a dependable and compact option for industrial applications requiring moderate pressure. Its stainless-steel body has a 4-inch diameter making it ideal for setups where space is limited. The heater features threaded inlet and exhaust ports which make installation easy. Two built-in Type K thermocouples ensure accurate temperature readings and allow for easy wiring. The Max handles pressures of up to 60 PSI and can handle inlet temperatures up to 200°F. It’s available in 6.0kW to 36.0kW, models, 240V/380V/480V 1ø / 3ø units. The Max Air Heater can be paired with a Max Control Panel to ensure precise temperature and prevent temperature overshoot. The Max Air Heater is a versatile choice for many industrial heating needs.

In comparison, the Threaded Inline Heater is used in demanding, high-pressure applications and processes requiring higher inlet temperatures. Its 304 stainless steel body features male NPT connections for secure, leak-proof fittings, and it can withstand pressures up to 150 PSI—well beyond the Max’s capabilities. The Threaded Inline Heater also supports inlet temperatures up to 900°F, making it ideal for extreme heating requirements. It is available in two styles: Style “A”, which provides a leak-proof design, and Style “B”, for more flexible applications. Unlike the Max, this heater requires separate Type K thermocouples and uses flying leads for wiring. For unique applications, it can even be tailored to specific requirements, though customizations may involve additional costs and lead times.

Ultimately, choosing between Max and Threaded Inline Heaters comes down to the specific requirements of your application. If you’re working with moderate pressures and lower inlet temperatures, the Max Air Heater is a reliable, compact solution. It’s user-friendly, with easy wiring and installation, and provides excellent performance for standard industrial processes. If  your project involves high pressures or extreme inlet temperatures, the Threaded Inline Heater’s durability and versatility make it the better option. Its ability to handle extreme conditions, combined with customization possibilities, ensures it can meet even the most demanding environments.

Both heaters are competitively priced, so the decision will likely be determined by your system’s pressure and temperature requirements. Whether you opt for the simplicity of the Max or the high-performance capabilities of the Threaded Inline, TUTCO SureHeat delivers quality solutions that deliver a high level of performance.
