What CiTECH does

CiTECH Energy Recovery Solutions (UK) Ltd is a UK-headquartered (Hessle, East Yorkshire) engineering firm that designs and manufactures bespoke Waste Heat Recovery Units (WHRUs), Once Through Steam Generators (OTSGs), and supporting exhaust system components for the global oil & gas, power generation, and process industries. Its core technology, the patented CiBAS (Concentric Integral Bypass & Silencing) WHRU, features a unique hanging tube support structure that eliminates vibration and thermal expansion limitations, enabling compact modular designs suitable for weight-constrained offshore platforms and supercritical CO2 applications. The company also offers traditional WHRUs, Twinstack configurations for higher thermal duty, OTSGs, exhaust systems, louvre dampers, silencers, and retrofit solutions, with manufacturing executed through a 4,272 sqm Malaysian fabrication facility integrated within its parent Muhibbah Engineering (M) Bhd group.

CiTECH generates revenue primarily through one-off, competitively tendered equipment supply contracts awarded by major EPCs (Siemens Energy, Petrofac, Hyundai Heavy Industries, TATA Projects) and operators (Shell, ExxonMobil, Chevron, Petrobras, ONGC, Lukoil, Statoil, ConocoPhillips, Maersk, Reliance Industries, SBM Offshore, North Oil Company). The company supplements equipment sales with engineering feasibility studies, commissioning services, operator training, and spare parts supply. Go-to-market is enterprise field sales supplemented by a network of appointed regional representatives across 13 countries and participation in major industry events (ADIPEC, OTC, Offshore Europe, ASME Turbo EXPO, SPE). Pricing is project-specific and not publicly disclosed.

Founded in 1936, CiTECH has deployed more than 250 bespoke WHRUs globally, including flagship references on the Sakhalin-1 Berkut platform (the world's largest oil platform), the Buzios 7 P-78 FPSO (the world's largest deepwater oil field), and the Gallaf platform in Qatar. The company holds ASME U, S, U2, and NBBI R Stamps, ISO 9001/14001/45001/29001 certifications, and Pemex Procurement International qualified supplier status, positioning it as a credentialed specialist in a niche segment of the oil & gas value chain where engineering track record and regulatory compliance are primary selection criteria.

• Hamon: Belgian engineering group specializing in heat recovery steam generators (HRSGs) and waste heat recovery solutions for power generation and industrial applications, competing with CiTECH for WHRU scope on similar global EPC and operator tenders.
• Sofinter: Italian industrial boiler and heat recovery group serving oil & gas, power and process industries with WHRUs and HRSGs, directly comparable to CiTECH's bespoke heat recovery units for upstream and downstream applications.
• John Cockerill (formerly CMI Energy): Belgian industrial group whose CMI Energy business designs and manufactures HRSGs and heat transfer equipment for power and process industries, directly competing with CiTECH for WHRU scope in global tenders.

Emerging players

• Enertime: French specialist in Organic Rankine Cycle (ORC) turbogenerators that convert waste heat into electricity, often using WHRU-style heat exchange. Adjacent technology overlap with CiTECH's OTSG and ORC-related WHRU offerings, particularly in low-to-medium temperature waste heat.
