For over 85 years, Bassett Mechanical has been a cornerstone of the mechanical contracting industry, evolving into a comprehensive solutions provider. Our journey into providing our refrigeration customers with solutions took a significant leap in 1979 when we began manufacturing ASME pressure vessels for ammonia refrigeration systems, laying the groundwork for decades of innovation, investment, and growth. Over the next decade, we honed our expertise, refining our processes and expanding our capabilities in response to industry needs. 

By 1992, our commitment to excellence led to the official registration of Thermatech. Thermatech quickly became an important and growing part of our business, reflecting its core focus on pressure vessels related to cooling equipment, chillers, and advanced thermal solutions. From the outset, Thermatech specialized in manufacturing ammonia-based chiller packages, reinforcing our long-standing reputation for quality and reliability in refrigeration. 

One of Thermatech’s early ventures outside of the refrigeration industry was the production of Saturation Diving Chamber systems that enable divers to remain submerged for extended periods. This unique product demonstrated our advanced engineering capabilities, high level of craftsmanship, and adaptability in pressure vessel fabrication. However, as shipbuilders began integrating dive chambers directly into their new vessel designs, the demand for standalone chambers declined, prompting Thermatech to strategically pivot towards other refrigeration and cooling solutions while also growing the focus on pressure vessels for a wider range of applications and industries. 

As we expanded into new markets, our pressure vessel business saw significant growth. To keep up with demand and manage our costs, we strategically invested in CNC cutting equipment, allowing us to produce pressure vessels more economically by reducing the manual labor associated with cutting plate steel and heads with penetrations, bevels, and layout lines. During that time, we also invested in a larger roll that allowed us to produce most pressure vessel shells in-house, ranging from 1 ¼” thick and up to 12 ft in diameter.  

Thermatech has maintained a steadfast commitment to innovation and excellence in metal fabrication throughout its decades of strategic evolution. This enduring history, marked by the production of over 14,000 vessels since our first small refrigeration unit in 1979, is built upon the foundation of our highly skilled associates’ commitment to delivering on time with a high level of quality. Our journey has seen us expand our expertise to craft a diverse range of high-quality thermal solutions and vessels for various industries, now reaching impressive dimensions of up to 16′ in diameter, 180′ in length, and 5” in thickness and a wide range of specialty alloys. This growth reflects our unwavering dedication to quality, adaptability, and technical excellence. 

Investing in Excellence: A Timeline of Technological Advancement

Our commitment to providing superior pressure vessels is evident in our ongoing investment in state-of-the-art equipment. Key milestones in our technological evolution include: 

• Start-up (1979 -1997): Registered our first ASME Refrigeration Vessel with the National Board in 1979 and welded vessels together in a 2-stall garage utilizing cherry pickers and floor jacks.  A roll, press break, and plasma table were used to complete the required components, but they were limited to thinner and smaller vessels. 

• Early Expansion (1997-2012): Moved to our current 300,000 sq. ft. manufacturing facility in 1997 and expanded our footprint and offerings.  Invested in press brakes, blast, and paint booth, weld positioners, and sub-arc welding equipment, significantly expanding our ability to handle larger and thicker materials. 

• Modernization and Growth (2012 -Present): Consistent investments in advanced manufacturing equipment and layout (additional overhead cranes, advanced multi-process welding machines, adjustable weld positioners, CNC Structural Profiler, and a CNC Pipe Profiler) to ensure efficient and high-quality fabrication.  Implemented a comprehensive digital workflow across our fabrication shop utilizing iPads at workstations and automated material and welder traceability.
