What Aerinox does

AERINOX Inc. is an environmental engineering company that designs, manufactures, commissions, and supports emissions control systems for stationary diesel and natural gas engines. Founded in 2012 and headquartered in Johnstown, Colorado, AERINOX operates as a joint venture between DCL Technology Group (parent, with a 300-400 person workforce spanning multiple industrial sectors and nearly 40 years of emissions reduction experience) and H+H Engineering & Service GmbH (an experienced supplier of SCR technology in the marine sector). Its core technology stack centers on Selective Catalytic Reduction (SCR) systems for NOx reduction (rated at up to 98-99% reduction), Diesel Particulate Filters (DPF) for particulate matter, Oxidation Catalysts (Oxicat) for CO and VOC reduction, and Ammonia Slip Catalysts (ASC), complemented by integrated data logging and on-line emission monitoring modules that interface with SCADA platforms. The product suite is engineered to meet Tier 4 Final, Clean Air Act, EPA emissions, and CARB compliance requirements for reciprocating engines and turbines from roughly 50 kW to 20 MW.

The company sells integrated turnkey systems, individual SCR components (catalysts, urea dosing modules, mixing elements, sensors, PLC controls, ammonia slip catalysts), and lifecycle service offerings including commissioning and on-site training plus catalyst inspection and replacement. Pricing is quote-based and tailored to engine specification and regulatory profile, consistent with long-cycle B2B capital equipment sales and multi-year relationships. Distribution runs through a direct enterprise field sales motion staffed by sales engineers who own named accounts and engage permitting managers, facility engineers, operations leads, and procurement teams at data centers, distributed power generation operators, gas transmission and storage operators, greenhouse cogeneration sites, and industrial and chemical producers across North America.

AERINOX cites 800+ commissioned SCR installations across the United States and more than two decades of accumulated design and manufacturing experience as evidence of durability, with monitoring, parts, and training work positioned as recurring touchpoints with the installed base. The business is privately held under the DCL Technology Group umbrella, with no disclosed external institutional ownership; the June 2026 appointment of a dedicated General Manager and explicit data center market focus point to a phase of commercial intensification.

Core offering

Aerinox designs, manufactures, and services integrated emissions control systems for stationary diesel and natural gas engines, including Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF), Oxidation Catalyst (Oxicat), and Ammonia Slip Catalyst (ASC) products. Offerings are delivered as turnkey systems or modular components and are supported by commissioning, on-site training, data logging, on-line emission monitoring, and catalyst inspection and replacement services. The portfolio is tailored to customer engine specifications, regulatory requirements, and operating environments across data centers, distributed power, gas infrastructure, industrial, and agricultural applications.

Product overview

AERINOX is an environmental engineering company providing a portfolio of integrated emissions control solutions for stationary diesel and natural gas engines. The core product portfolio centers on three main technology categories: Selective Catalytic Reduction (SCR) systems as the primary NOx reduction solution, Diesel Particulate Filters (DPF) for particulate matter capture, and Oxidation Catalysts (Oxicat) for CO and VOC reduction. These are complemented by Ammonia Slip Catalysts (ASC) as an add-on component, plus data logging and on-line emission monitoring modules that integrate with the core systems. The company also offers commissioning and on-site training services, and catalyst inspection/replacement as part of lifecycle support. Solutions are available as complete turnkey systems or individual components, and are tailored for engines ranging from 50 kW to 20 MW across data center, power generation, industrial, and gas infrastructure applications.
