What Deltech Furnaces does
Deltech Furnaces (Deltech, Inc.) is a privately held, family-owned custom manufacturer of electric resistance-heated furnaces, founded in 1968 and headquartered in a single manufacturing facility in Denver, Colorado. The company designs and builds bespoke thermal-processing systems including bottom-load, front-load, top-hat, vertical-tube, horizontal-tube, rotary-tube, glass-melt, positive-pressure (up to 1700°C / 1500 psi), and ultra-high-temperature furnaces capable of in-air operation at up to 2000°C — a range described as rare among US suppliers. Core proprietary technology centers on MoSi2 heating elements, NASA-designed water-cooled end caps, and Intertek UL508A-certified control systems with HMI/PID programming, all built around ISO 9001:2015 quality management with ASME NQA-1:2008, NFPA 86, UL 1203, and C1D2 hazardous-location certifications that gate nuclear, aerospace/defense, and hazardous-environment sales.
The company serves research laboratories (universities, government labs such as NASA JPL, ORNL, Battelle, Johns Hopkins, and Indian institutes CGCRI/ARCI/LASTECH), ceramics and glass manufacturers (Corning, Schott, CoorsTek), aerospace and defense customers (Boeing, GE Aviation, Raytheon), and the nuclear industry. Revenue is generated through quote-based one-time sales of custom furnace systems, supplemented by recurring spare-parts and aftermarket service revenue, on-site and in-house repair/rebuild work (including for competitor equipment), and a toll-firing service whose fees can be applied to subsequent furnace purchases; 2% net 10 payment terms are offered. GTM is sales-led and enterprise-field-sales driven, executed through direct phone/email/website-quote engagement from Denver and a four-region international rep network covering Canada (Safe-T-Air), India (Arcom Enterprises), Latin America (Heptatec), and Mexico (ATG Instrumentacion), with brand-building via trade shows (Ceramics Expo, CCAC), educational sponsorships, and a blog/tutorials library.
The business remains family-controlled under the Stevenson family, with all design, manufacturing, and shipping consolidated in Denver. Leadership continuity is in transition following Mary Stevenson's July 2023 step-back from operations, and the company holds a 2023 SBA Region VIII Exporter of the Year recognition alongside ongoing workforce-development partnerships (Pathways to Prosperity: Advanced Manufacturing, Manufacturers Edge) and community sponsorships (Westminster Public Schools Foundation, CoorsTek Family for Families) that indicate continued operational activity into 2024-2025.
