Partnership to Support Next Phase of Growth and Drive Technology Advancements for OEM Equipment, Broadly Serving Domestic Manufacturing and Industrial End Markets

Angeleno Group, a Los Angeles-based investment firm providing venture capital and growth equity to clean energy and climate solutions companies, announced today its investment in NESTEC, a leading original equipment manufacturer and service provider of industrial air pollution control (APC) systems. The commitment will support NESTEC's continued expansion across existing and new end markets, including renewable fuels, packaging, municipal waste, biomass, engineered wood products, food and beverage, construction materials and semiconductors. The investment also enables NESTEC to pursue geographic expansion and expand product development strategies.

Founded in 2005 and headquartered in eastern Pennsylvania, NESTEC designs, manufactures, installs and services state and federally regulated air emissions control systems that address volatile organic compounds (VOCs), hazardous air pollutants (HAPs), PM 2.5, acid mist emissions and odor control. The company's solutions are deployed across highly specialized, advanced manufacturing and other industrial sectors, developing novel solutions for emerging markets and ultimately establishing Maximum Achievable Control Technology (MACT) compliance standards for industry.

With an installed base of over 150 systems in the field, the company drives recurring revenue through maintenance, performance upgrades, parts and service work for both replacement and greenfield projects across NESTEC and competitor fleets. NESTEC's differentiated platform combines highly engineered APC systems and integrated supporting technologies, all supported with a scaled aftermarket services offering. NESTEC operates in over 35 states and across Canada and has been recognized for its experienced technical team, engineering credibility and focus on improved reliability and minimizing both fuel and electrical costs for its customers.

“NESTEC is a trusted operator in a needs-driven market where reliability, uptime, and industry experience are absolutely critical,” said Anil Tammineedi, Partner at Angeleno Group. “The company’s long-standing customer relationships, world-class leadership, and full-stack OEM capabilities — including unique features designed to minimize both fuel and electrical costs — position NESTEC to be a national leader in lowering costs while advancing more sustainable, efficient industrial operations. Amid a resurgence of domestic manufacturing and accelerated onshoring, we are thrilled to support NESTEC’s continued growth.”

“The growth NESTEC has achieved over the past two decades is a testament to its team’s ability to combine deep technical expertise with a genuine commitment to customers and the communities they serve,” said Danny Jaffe, Partner at Angeleno Group. “NESTEC consistently demonstrates that rigorous emissions control, meaningful energy conservation, and cost reduction are complementary goals, not competing ones. By helping industrial facilities increase efficiency while controlling harmful emissions, these solutions deliver outcomes that benefit both the bottom line and the health and well-being of surrounding communities. NESTEC has built something special in terms of technical expertise, customer trust, and aligning its mission with its impact.”

“At NESTEC, our drive has always been to deliver the most effective, reliable and economical air pollution control solutions, not just to meet regulatory requirements, but to genuinely reduce our customers’ environmental footprint and operating costs,” said Jim Nester, Founder and CEO of NESTEC. “Our commitment to our customers, employees and vendors is the pillar we built upon to create a respected environmental solutions provider. Working with Angeleno Group will help us expand our platform to bring that mission into new end markets and geographies, from clean energy and semiconductors to waste processing. We see a significant opportunity to bring that same standard of excellence to a much broader set of industries.”

“We are excited to partner with Angeleno Group as we continue to expand and strengthen the essential systems our customers rely on,” said Jaymie Deemer, President of NESTEC. “Angeleno brings long-term, sector-focused capital and a strong network that will help us continue responsible growth, while staying true to the responsiveness and technical excellence our customers count on.”
