What Tutco Sureheat does

TUTCO SureHeat manufactures high-temperature electric process air and gas heaters for industrial and aerospace applications. The company is a subsidiary of Smiths Group plc (LSE: SMDS), headquartered in Exeter, New Hampshire, and operates alongside other TUTCO Heating Solutions Group brands. Its core technology is the proprietary Serpentine™ open-coil heating element, which enables compact designs roughly one-third the size of conventional heaters and supports temperatures up to 1922°F (1050°C) and power ratings above 1 MW in configurations such as the Specialty Flanged Inline (SFI) line.

The product portfolio spans the Jet, Max, Max HT, Threaded Inline, Triple-Pass, and Specialty Flanged Inline (SFI) heaters, plus Hot Air Tools and Series Spot heaters, paired with Eurotherm-based control panels. Applications include aerospace testing and manufacturing, automotive, electronics, plastics processing, medical equipment, food and beverage, printing, and R&D/energy work including hydrogen, CO2, syngas, and iron powder combustion via a partnership with RIFT. Customers include NASA, SpaceX, Boeing, Pratt & Whitney, Honeywell Aerospace, GE Global Research, Safran, Northrop Grumman, and ANA.

The business model is direct enterprise sales with quote-based pricing on custom-engineered units and replacement elements. The 2024 acquisition of WATTCO (Montreal, Canada) extended North American manufacturing capacity and product breadth. End markets are diversified across aerospace and defense, automotive, electronics, plastics, medical, food and beverage, printing, and emerging clean energy segments, with aerospace primes representing a visible but not exclusively disclosed share of revenue.

Partnerships

One partnership is on record.

• RIFTflagshipStrategic or Co-development PartnerTUTCO SureHeat has partnered with RIFT, a Netherlands-based clean energy company, to supply Specialty Flanged Inline (SFI) heaters for RIFT's Direct Reduction of iron oxide (DRI) process in RIFT's Iron Fuel Technology™. In this process, hydrogen is heated to elevated temperatures under moderate pressure to reduce iron oxide (rust) into elemental iron powder—the key step in RIFT's carbon-free fuel cycle. TUTCO's SFI heaters provide reliable high-temperature performance, compact space-saving design, fast heat-up times, and flexible scalable configuration for the DRI system. RIFT aims to cut 1 gigaton CO₂ emissions annually by 2050, and TUTCO's heaters are a key enabling component of this technology.
