Airtek Construction

What Airtek Construction does

Airtek Construction is a privately held Troy, Alabama-based provider of electrostatic precipitator (ESP) air pollution control equipment and related heavy-industrial services, founded in 1988 (originally as Mark III – APSG). The company designs, engineers, constructs, rebuilds, and services ESP installations and adjacent air pollution control equipment for power generation plants, pulp and paper mills, petrochemical facilities, cement and rock products operations, and steel manufacturers, primarily across the Southeastern United States. Its customer base is overwhelmingly enterprise and outage-driven, with the firm claiming that 80% of its business comes from repeat customers and several accounts on nearly 30 years of consecutive service.

The technical core is a portfolio of proprietary ESP components: the Rigid Discharge Electrode (RDE), a structurally rigid 1.5- or 2-inch tube-based corona electrode with welded pin customization; a Direct Plate Rapping System that transfers rapping energy directly into collecting plates to reduce re-entrainment; shop-assembled roll-formed collecting plates with tubular edges to prevent arcing; and custom-engineered voltage controls and high-frequency power supplies. The company reports engineered, designed, constructed, and performance-guaranteed the last 6 of 6 new recovery boiler precipitators built in the United States over a 20-year window, and has completed 210+ precipitator rebuilds and 2,000+ maintenance projects cumulatively.

Airtek operates a multi-stream revenue model. Equipment Sales generates one-time OEM revenue from new ESPs; Parts and Equipment Supply produces transactional revenue from over $3 million in inventory across 200,000+ square feet of warehouse supporting 15+ legacy OEMs; Construction and Maintenance plus Field Service produce professional services revenue from turnkey outage execution backed by 250-300 open-shop craft at peak season; Engineering and Precipitator Rebuilds produce project-based professional services revenue from the firm's multidiscipline engineering staff. Pricing is quote-based and project-based; distribution is direct enterprise field sales, with the company self-describing as having the largest field service team in the ESP industry. Airtek is privately held with no disclosed external funding, no parent company, no subsidiaries, and no publicly disclosed revenue.

Core offering

AirTek Construction custom-designs and manufactures electrostatic precipitators (ESPs) and provides complete engineering, construction, maintenance, and field service support for industrial air pollution control. Offerings span new OEM ESPs, precipitator rebuilds, replacement parts inventory ($3M+ across 200,000+ sq ft), engineering design, and direct-hire on-site construction and maintenance labor deployed to power plants, pulp and paper mills, petrochemical, cement, and steel facilities.

Product overview

Airtek Construction offers a comprehensive portfolio of air pollution control (APC) equipment and services centered on electrostatic precipitators (ESPs). The company's core offerings include new OEM electrostatic precipitators, precipitator rebuild services, parts and equipment supply, engineering services, construction and maintenance, and field service. These products are supported by proprietary component modules including Rigid Discharge Electrodes (RDE), Direct Rapping Systems, Collection Plates, and Voltage Controls and Power Supplies. The company also supplies auxiliary equipment such as wet/dry scrubbers, baghouses, fans, and material handling systems. This is a services-and-equipment provider rather than a software platform—the offerings function as an integrated system where new equipment, rebuilds, parts, engineering, and field service work together to maintain and optimize customer precipitator installations throughout their operational lifecycle.
