Industrial Service Solutions

What Industrial Service Solutions does

Industrial Service Solutions (ISS) is a privately held, Houston-headquartered provider of industrial maintenance, repair, and overhaul (MRO) services operating 50+ service locations and approximately 2,500 employees across the United States, claiming the position of largest independent industrial MRO provider in the country. The company manufactures, services, and integrates rotating equipment (electric motors from fractional to 20,000 HP, pumps, compressors, valves, gearboxes) and process equipment (boilers, heat exchangers, kilns, material handling), supported by the proprietary Spectare AI-based remote condition monitoring platform, the PowerCube oilfield electrification system, and the Revolution Series top drive motors. ISS's Houston Center of Excellence houses the largest motor test facility in North America, capable of full-load testing up to 6,000 hp and no-load testing up to 20,000 hp.

ISS generates revenue through three primary streams: (1) MRO field and shop services delivered via 50+ regional shops and mobile field technicians on a project/contract basis (the largest revenue stream); (2) equipment and spare parts sales through direct field sales and the eindustrialsolutions.com e-commerce portal; and (3) engineered-to-order power systems, including electric motor packages, automation and control systems, and proprietary PowerCube electrification systems. The company sells primarily to operations managers, plant engineers, and procurement teams at industrial facilities across power generation, marine (including the U.S. Navy), oil and gas (upstream, midstream, downstream), cement and aggregates, chemical and petrochemical, water and wastewater, pulp and paper, general manufacturing, transit and railroad, mining and metals, and food and beverage sectors. Pricing is quote-based and project-specific; no public rate cards are published.

ISS operates as a Wynnchurch Capital portfolio company and has grown predominantly through serial acquisitions since 2012, including Bay Valve (2012), AmeriMex Motor & Controls and Power Systems (2013), Servo South (2022), Electric Motor Technologies (2024), and most recently MSHS Pacific Power Group (February 2026), which added 10+ locations, 450+ staff, and 150+ OEM authorizations. In October 2024, ISS divested its non-core ISS Inspection Services segment to Element Materials Technology to refocus on core rotating equipment operations. The company holds 25+ certifications including ISO 9001:2015, NAVSEA, FAA, NADCAP, EASA, IEEE, and UL Listed, which qualify it for defense, aerospace, nuclear, and other regulated-customer work.

Revenue model

1. MRO Field and Shop Services: ISS generates the majority of its revenue through maintenance, repair, and overhaul services delivered via its nationwide network of 50+ regional service shops and field technicians. Services cover rotating equipment (motors, pumps, compressors, valves, gearboxes), process equipment (boilers, heat exchangers, kilns, dryers), and specialized systems (power generation, marine, national security). Revenue is earned on a project/contract basis with both one-time service engagements and long-term maintenance agreements.
2. Equipment and Spare Parts Sales: ISS sells new industrial equipment (motors, pumps, valves, compressors, controls) and spare parts through its e-commerce portal (eindustrialsolutions.com) and direct sales teams. Revenue is generated on a per-transaction basis for both standard catalog items and custom-manufactured equipment.
3. Engineered Power Systems: ISS designs, manufactures, and sells engineered-to-order power systems including electric motor packages, automation and control systems, power generation sets, and the proprietary PowerCube electrification system. These are sold as integrated solutions or individual components to upstream oil & gas, power generation, and industrial customers.
