Environmental, Social, and Governance (ESG) Principles
Clean air isn’t a checkbox — it’s a responsibility. Our mission supports:
Environmental Stewardship
We reduce harmful emissions — NOx, HC/VOC, CO, and CO₂ — that drive smog, poor air quality, and climate change. We also convert CO₂ into plant-nourishing fertilization solutions, turning a pollutant into a resource.
Social Responsibility
Our solutions help protect communities from engine emissions in urban and industrial environments. We partner with clients to meet environmental health and safety targets through smarter, more effective emissions control.
Governance & Compliance
We keep pace with evolving emissions standards and help clients maintain compliance with EPA, CARB, and local regulations. Our systems are built for traceability and audit-readiness, making ESG reporting straightforward.

Pete Hinzy
General Manager
With 25+ years of manufacturing and operations leadership, Pete oversees the design, engineering, manufacturing, and commissioning of SCR, DPF, and oxidation catalyst aftertreatment systems for large stationary engines across the data center, distributed power, oil & gas, and industrial markets.

A mechanical engineer by training — BSME from Rose-Hulman Institute of Technology, MBA from Indiana Tech, and Six Sigma Black Belt — Pete has built his career leading operational transformations and P&L turnarounds at PE-backed and industrial businesses including Bosch Automotive, Crane Pumps & Systems, Prater Industries, Sundyne, and RCI Offroad. His experience spans multi-site manufacturing, lean transformation, supply chain, new product development, and building high-performance teams.
Pete applies that background to a business at the intersection of environmental performance and industrial power — helping customers meet increasingly stringent emissions requirements while maintaining the reliability their operations demand. His focus is on scalable, standardized aftertreatment solutions backed by responsive engineering support and long-term service relationships.
Pete is based in Lyons, Colorado, near our Johnstown facility.
Cameron Allen
Engineering Manager
Cameron leads the engineering team through the design, development, and delivery of custom emissions control systems. He works with customers, project managers, manufacturing, and field service to ensure every system is designed well, built correctly, and supported through startup and long-term operation.

With over 16 years of industry experience, Cameron brings deep expertise in emissions control, mechanical design, automation, controls integration, and field support. His background spans oil and gas, energy, industrial process, and data center applications. Before AERINOX, he worked in automation engineering at Dresser-Rand (now part of Siemens Energy), supporting emissions control systems for large natural gas engines.
Cameron holds a Mechanical Engineering degree from Colorado State University and has hands-on experience with selective catalytic reduction systems, SolidWorks, AutoCAD, PLCs, data analysis, and commissioning. He’s known for finding practical solutions that work in the field — not just on paper — and for bringing the same level of care to supporting customers as he does to supporting his team.
Cameron is based in Northern Colorado and is also an Eagle Scout.
Danielle Johnson
