What Environmental Equipment Services does

Environmental Equipment Services (EEServ) is a privately held, vertically integrated custom manufacturer of ASME Section VIII Division 1 pressure vessels, shell and tube heat exchangers rated to 3000 PSIG, sulfonation systems, ammonia-related process equipment, and chemical injection skids. The company operates from Casa Grande, Arizona, with affiliate heavy-machining capacity through Casa Grande Machine & Welding, and serves power generation utilities, LNG/energy operators, chemical and surfactant producers, EPC firms, and government customers across the US, South Africa, Morocco, and India. Core technology capabilities include a Mighty Viper VTL-20-25 4-axis CNC vertical turning center handling 85-inch diameter, 98-inch swing, 60-inch height workpieces up to 44,000 lbs with deep-hole drilling beyond 13x drill diameters, qualified welding procedures for Inconel, Hastelloy, and Duplex SS 2205, PLC programming for automated controls, and 85+ combined years of inherited Chemithon sulfonation engineering covering sulfur burning, SO3 generation, and falling film reactors.

EEServ's business model is project-based custom fabrication priced per RFQ, complemented by field services (ammonia PSM audits, HAZOP studies, commissioning, 24/7 emergency response, and API 510 tank inspections delivered through the NH3 Services partnership) and replacement-parts/hardware sales. Revenue is generated one fabrication order, one service engagement, or one parts shipment at a time, with no disclosed recurring subscription or service-contract structure. Certifications held include ASME U and R stamps, ASME Section VIII Division 1, ANSI B31.3, TEMA, API 510, and OSHA PSM compliance, which collectively position the company in the qualified-vendor pool for regulated utility, LNG, and chemical-process work.

Customer concentration is tilted toward US investor-owned and public-power utilities (TVA, Southern Company and subsidiaries, Ameren UE, Consumers Energy, DP&L, Eskom, TAQA Morocco), with secondary exposure to LNG/energy (Prometheus Energy, Howden, IPL Energy), EPCs (Harris Group, GE), and government (US DOJ). The management team — President/CEO Mike Vukmir (18 years Chemithon), VP Engineering John Chittenden PE (30 years), VP Production/QC Tod Derks (15 years), and Sulfonation Engineer Paul Schoen (25 years) — is the principal carrier of the company's sulfonation process know-how, and the depth of this bench is a meaningful gating factor for any organic scale-up or competitive entry.
