Invisible yet essential, industrial gases are all around us-surrounding our daily lives in ways most of us never pause to consider.
Whether it's the oxygen coursing through a hospital ward, the nitrogen keeping packaged foods fresh, the carbon dioxide in your favorite sparkling beverage, or the high-purity gases fueling semiconductor fabrication, medical imaging and green energy, these foundational elements quietly drive much of our modern world.
As David Bell retires after nearly two decades as founder and president of WITT Gas Controls of Alpharetta, GA, the industry he has helped shape looks nothing like the one he entered nearly fifty years ago. Back then, the industrial gas sector was a tightly focused world, a fraction of today's market, largely limited to heavy industry and traditional manufacturing. Now, it's a dynamic, ever-expanding driver of technology, health, and sustainability, underpinning everything from advanced medical diagnostics to sustainable agriculture and green energy solutions.
A Leader Who Inspires Confidence In An Evolving Market
The industrial gases industry's story has also been one of global interconnectedness, mergers and acquisitions, and shifting regulatory landscapes. As companies like BOC, Linde, and Airgas consolidated or expanded, cross-border best practices and competitive pressures increased. "Going global means what works in the U.S. doesn't always work in the EU or Asia," Bell notes. "You have to respect local regulations, cultural expectations, and market realities."
This globalization also propelled innovation. "Different countries prioritized different growth sectors. Europe pushed early on for green energy and specialty gases for research and the U.S. drove advances in industrial fabrication and high-volume food processing. Every region taught us something new."
For business leaders, Bell argues, the lesson is straightforward: "Diversification isn't just a buzzword. In this business, it's survival. The companies that thrived were those who didn't just serve one niche, but continually looked ahead, anticipated emerging markets, and invested in R&D before the need was urgent."
An Expert at Managing Change: Bell Innovates Through Technology, Talent, and Mindset
Managing people and technology through change is at the heart of sustained business success. Bell's philosophy, "Every problem is really an opportunity waiting to be solved", became woven into the culture at WITT Gas Controls and beyond. "We always encouraged teams to engage with customers' toughest challenges rather than shy away from them," he says.
Even as evolving technology brought new efficiencies, it demanded new skills and agility from employees. "I remember when mainframes and punch cards ruled the day, and then suddenly everyone needed to master PCs, networked systems, and now digital platforms," Bell remembers. He credits open-minded, cross-functional teams for helping companies stay ahead: "You can't afford silos. Field techs, engineers, account managers, we all bring different perspectives, but we needed to share the goal."
During the COVID-19 pandemic, for instance, WITT Gas Controls USA managed to keep operating seamlessly while prioritizing employee safety. "We were nimble and quick in becoming a nearly 100% remote company, practically overnight. Investment in digital systems and smart use of inventory kept us moving when so many others stumbled," Bell tells FM Magazine.
These transformations changed the standards of excellence. "Today, customers expect not just a product, but responsive support, easy communication, and transparent data. Agility and adaptability are as valuable as expertise," Bell says.

The Unbreakable Legacy
Bell leaves behind a transformed WITT Gas Controls, recognized for its leadership in laser fabrication, medical imaging, and food safety. The company now stands as a benchmark for precision and reliability, earning the trust of companies where performance matters most.
Looking ahead, WITT is well positioned for new frontiers in hydrogen technology, digital sensors, and hybrid solutions. Bell's practical wisdom still guides its path. "Keep it simple; the world is complex enough," he often advised. His clarity of purpose and focus on people shaped a company culture built on collaboration, innovation, and integrity.
Bell's leadership raised standards across the industry and fostered an environment where problems became opportunities. After many years leading WITT Gas Controls USA and a lifetime of contribution, David Bell retires having strengthened not only a company but also the industry itself, leaving a foundation that will endure for years to come.
