What HydroChemPSC does

HydroChemPSC, operating as HPC Industrial powered by Clean Harbors, is an industrial cleaning, specialty maintenance and environmental services company headquartered at 900 Georgia Avenue, Deer Park, Texas. Founded in 1977 and now a wholly-owned subsidiary of Clean Harbors following Littlejohn & Co.'s August 2021 exit, the company is the nation's single largest provider of industrial cleaning services to the downstream energy industry. Its portfolio is organized into three divisions: Downstream (refining, petrochemical, power), Specialty / Engineered Services and Upstream oil and gas, with operations across 90+ facilities in all 50 U.S. states and a workforce of 5,500+. Service offerings span hydroblasting, tank cleaning, chemical cleaning, wet/dry vacuuming, ultrasonic cleaning, LDAR (leak detection and repair), vapor control, specialty mechanical (hot tapping, line stops, leak repair), pigging and decoking, pipeline integrity inspection, UAV/drone inspection, water filtration, and integrated container management covering over 7,500 units in North America.

The proprietary technology stack is anchored by a 25,000-square-foot HPC Innovation Center in Canal Fulton, Ohio (25 full-time engineers) and a fleet of 40+ EcoRobotics robotic cleaning systems acquired in May 2024. Differentiated technologies include the Computerized Tube Cleaning System (CTCS) with automated indexing and up to four simultaneous lances delivering 50% faster cleaning, 30-50% water reduction and 40% CO2 reduction; exclusive North American rights to Ultrasonic Cleaning Technology for oil, gas and petrochemical (75-95% water reduction); the only ISO 9001-2015 certified LDAR calibration lab; patented pigging technologies with the industry's largest twin-pump fleet; and FAA-licensed UAV services for confined-space inspection, LiDAR, bathymetry, thermal imaging and digital twin creation. A Safety 3-6-5 program underpins deployment.

The business model is B2B enterprise field sales supported by an embedded InSite on-site contracting model, with dedicated teams placed at over 100 refining and petrochemical facilities. Revenue is generated primarily through professional services (project-based work, turnaround contracts, LDAR compliance, vapor control and specialty mechanical retainers) plus managed services (container and equipment rental, on-site fixed facility design and operation). Long-tenured anchor customers include Marathon Refinery (Robinson), Chevron Richmond, Covestro (35-year relationship, 2022 Contractor of the Year), Dow Chemical (2018 Diamond Award), ExxonMobil/SABIC, CITGO Lake Charles (10-year no-OSHA-recordable LDAR program) and Pemex Deer Park, with case-study outcomes ranging from $4.5M in annual fuel-gas savings on leak repair to $110M in fuel cost reduction from ultrasonic chemical cleaning.
