What Diversified Heat Transfer does
Diversified Heat Transfer (DHT) is a US-based manufacturer of heat exchange equipment and systems, founded in 1938 and headquartered in Towaco, New Jersey. The company designs, engineers, and manufactures a broad portfolio spanning residential, commercial, industrial, and medical applications — including indirect water heaters, tankless coils, brazed plate heat exchangers, helically corrugated E-ZEE Flow heat exchangers, semi-instantaneous and instantaneous water heaters, unfired steam generators, shell-and-tube and plate-and-frame heat exchangers, HVAC coils, and electric boilers — sold under proprietary trademarks including Techtanium, Lindy Coil, Supertherm, SuperPlate, SuperSteam, and E-ZEE Flow. Underlying these products is a technology platform combining brazed-plate and shell-and-tube construction, advanced PID control systems with native BACnet IP and Modbus IP/MSTP integration for building management systems, and ASME-certified pressure-vessel manufacturing. The SPC Series also targets medical imaging cooling for MRI and CT scanners.
The company operates through three business segments — Residential/Wholesale, Commercial/Industrial, and Sussman Electric Boilers (acquired in 2022) — and generates revenue primarily through hardware sales of heat exchange equipment. Distribution runs through a manufacturer-rep network with a public rep-locator, complemented by direct sales via the company website, dedicated sales teams, and OEM replacement coils cross-referenced to installed-base equipment from Trane, Lennox, McQuay, York, and Daikin. Pricing is quote-based across all product categories. Products carry multiple industry certifications including ASME Section VIII-1, ASME IV (Part HLW), UL/cUL, AHRI 400, NSF 61, TEMA, PED, and KHK, covering US, Canadian, European, and Japanese pressure-vessel and potable-water requirements.
The 2022 acquisition of Sussman Electric Boilers repositioned DHT for the commercial building electrification and decarbonization tailwind. Sussman's EWx Series Electric Hot Water Boiler has been aggressively expanded since its January 2025 launch — growing from 32 models (270–1200 kW) to 43 models spanning 30–1200 kW by May 2026 — targeting healthcare, education, and commercial electrification projects. Leadership includes Jake Goldberg as President and CEO and Neil Pilaar as VP Sales of the Sussman subsidiary. The company is privately held with 51–100 employees and no disclosed funding rounds.
