What LDX Solutions does

LDX Solutions is a custom-engineered air pollution control and pneumatic conveyance systems designer and manufacturer headquartered in Kennesaw, Georgia, operating since 1947 with 51-100 employees. The business is organized around three proprietary sub-brands — Dustex (dry air pollution control technologies), Geoenergy (wet scrubbing, Wet ESP, and thermal/catalytic oxidizers), and Western Pneumatics (dust collection and material handling for the wood products industry) — collectively representing more than 150 years of combined expertise. Its product portfolio spans acid gas control (Circulating Dry Scrubber with >99% SO2 and HCl removal, wet scrubbers, Dry Sorbent Injection), mercury and heavy metals control via Activated Carbon Injection, NOx control via SCR/SNCR, particulate collection via baghouses, wet ESPs and cyclones, VOC destruction via RTO and RCO oxidizers, and pneumatic conveyance systems, with cumulative installed base exceeding 300,000,000 cfm of emission control capacity.

The company serves regulated heavy-industry end markets including cement, power and industrial boilers, pulp and paper, metals, mining, petrochemicals, semiconductors, building materials, waste-to-energy, and wood products/biomass, with five verticals (cement, power/boilers, pulp and paper, wood products/biomass) flagged as primary. Revenue is generated through three streams: one-time capital equipment sales of custom-engineered systems, engineering and EPC project delivery (process, mechanical, piping, civil/structural, electrical, and project/construction management), and recurring aftermarket parts, retrofits, technical audits, field services, and training covering both proprietary and OEM equipment. Go-to-market is a direct enterprise field-sales model with engineering-led consultation, supported by a multilingual website (English, Spanish, Finnish, Swedish, Russian) and regional U.S. offices in Kennesaw (HQ), Acworth, Eugene, and Ruston.

On February 3, 2025, LDX Solutions was acquired by ANDRITZ AG, an Austrian publicly-traded technology group headquartered in Graz, with William Blair acting as exclusive financial advisor to LDX. LDX operates within ANDRITZ's Clean Air Technologies portfolio, continues to offer the Dustex, Geoenergy, and Western Pneumatics brands, and is transitioning its corporate name from LDX Solutions to ANDRITZ while retaining its U.S. offices, customer relationships, and service operations.
