IMMI Turbines

What IMMI Turbines does

IMMI Turbines, Inc. is a privately held, independent industrial gas turbine parts and services company headquartered in Conroe, Texas, founded in 1999. The company explicitly positions itself as not affiliated with any OEM and serves operators of legacy and mid-class turbine fleets — including Solar Turbines (Saturn, Centaur, Taurus), GE Frame (1, 3, 5, 7, 9), GE Aero-derivative (LM2500, LM6000), Pratt & Whitney, Ruston, and Rolls-Royce Avon. Core capabilities span parts supply (new, refurbished, used, surplus, and reverse-engineered), full major overhauls, exchange programs for major assemblies, gearbox and generator maintenance, PLC-based control system retrofits, an in-house 5 MW full-load test facility, on-site commissioning, field services, and turnkey power plant design and installation. Differentiators include claimed pricing 25-50% below OEM, a 12-month parts warranty, 24-48 hour quote turnaround, and one of the largest turbine parts inventories in the world.

The business is monetized through direct, quote-based sales to enterprise customers across natural gas pipeline and distribution, offshore and onshore oil & gas, petroleum refining, power generation and utilities, and industrial co-generation (notably ethanol). Pricing is opportunistic — quote by quote — with no public rate cards, and the parts business carries a 12-month warranty. Revenue streams include one-time parts sales, professional services (overhauls, field services, control upgrades, commissioning), transaction-based exchange programs, and managed-service-style turnkey EPC contracts. The company has historically pursued large lumpy contracts (e.g., a $347M Libya utility project in 2014 and a $3.2M Iowa cogen plant in 2015) alongside a stream of repeat enterprise overhauls for customers such as Northern Natural Gas, TransTexas Gas, Shell Petroleum, Dubai Petroleum, Gazprom, and Southwest Gas.

IMMI distributes exclusively through direct sales — website quote forms, parts-search functionality, phone (+1 936 788 2229), and email ([email protected]) — reaching enterprise customers globally from its Conroe, Texas headquarters. The company's geographic reach is global on a project basis (USA, UAE, Russia, UK, Malaysia, Libya) but the operating footprint is single-site. Ownership and leadership are not publicly disclosed, and the company carries no disclosed outside funding, parent entity, or acquisition activity, operating as an independent private corporation.

Broad incumbents

• Mitsubishi Power: OEM of heavy-duty industrial gas turbines (e.g., M501/M701 series) and a major provider of turbine aftermarket services. Comparable broad incumbent competing for installed-base service revenue.
• GE Vernova: OEM of GE Frame 1/3/5/7/9 and GE Aero-derivative (LM2500, LM6000) turbines and large-scale service provider. IMMI is explicitly independent from GE and supports parts/overhauls for the legacy GE industrial fleet.
• Solar Turbines (Caterpillar): OEM of Solar Saturn, Centaur, Taurus, and Mars gas turbines and a Caterpillar subsidiary. IMMI is explicitly independent from Solar and provides aftermarket parts and services for the installed Solar fleet.
• MAN Energy Solutions: OEM of large industrial gas turbines (formerly MAN Diesel & Turbo) and provider of aftermarket service for power generation and oil & gas applications. Comparable broad incumbent serving similar industrial gas turbine customers.
• Sulzer: Swiss industrial services and turbomachinery OEM/aftermarket provider offering repair, overhaul, and field services for rotating equipment including gas turbines. Overlaps with IMMI's service portfolio across multiple industries.
• Siemens Energy: OEM of large industrial gas turbines and provider of aftermarket service. IMMI supports legacy Rolls Royce Avon / Ruston units that now sit within Siemens' industrial gas turbine portfolio.

Direct peers

• EthosEnergy: Independent provider of operations, maintenance, and aftermarket services for industrial gas turbines and other power generation assets. EthosEnergy competes most directly with IMMI in the independent O&M and parts replacement space for legacy OEM fleets.
• TGM Services (Turbine Generator Maintenance): Independent turbine and generator field services provider offering outage support, maintenance, and repairs for industrial gas turbines. Comparable to IMMI's field services and overhaul offerings.
• Mechanical Dynamics & Analysis (MDA): Independent provider of vibration monitoring, field testing, balancing, and engineering services for turbomachinery. Comparable to IMMI's full-load testing facility and performance/condition monitoring capabilities.
• Power Systems Manufacturing (PSM): Independent gas turbine parts manufacturer and repair shop specializing in hot gas path components, new units, and aftermarket services. Closest direct competitor to IMMI's parts manufacturing and overhaul business.
