Montajes Industriales EOS

What Montajes Industriales EOS does

Montajes Industriales EOS, S.A. (MIESA) is a privately held Spanish industrial equipment distributor and in-situ service provider founded in 1989 and headquartered in Casarrubuelos, Madrid. The company specializes in three intertwined lines of work: (1) the sale and rental of specialized industrial equipment for weld heat treatment (PWHT), controlled bolting and tensioning, in-situ machining, tube bundle extraction and cleaning, valve repair and testing, and hydraulic actuation; (2) the direct provision of on-site industrial services in those same disciplines, delivered by MIESA's own qualified technicians; and (3) technical training and equipment repair/calibration performed at its own workshops. Its principal customers are large industrial operators in oil refining, petrochemical, nuclear power, naval, solar thermal, combined cycle, and chemical processing, where shutdown-minimizing in-situ interventions are critical.

MIESA does not manufacture core equipment. Instead, it acts as the exclusive or long-standing Spanish (and select South American) representative for a portfolio of seven premier global OEMs: Stork-Cooperheat (PWHT equipment including the Cooper36 36-channel unit and Advantage 3/Cooper8 temperature programmers), SPX Bolting Systems (hydraulic tensioners and torque wrenches including SRT, WDD wind-turbine models, TWHC/TWSD/TWLC/TWSL series), Unigrind (portable valve lapping, the patented Legatest in-line safety valve testing system, and mobile workshop containers), Peinemann Equipment (tube bundle extractors, the Orion Indexer hands-free cleaner, and XXLTC high-pressure cleaning), Teco Tube Expanders (tube expansion tools and the Teco Tube Traktor high-speed extractor), Power Team (hydraulic cylinders, pumps, and the MCS synchronized Motion Controller System), and Mactech Europe (hydraulic diamond wire saws for offshore decommissioning, including ROV-compatible models for operations up to 3,000 m depth). This representation model allows MIESA to offer equipment from European and U.S. manufacturers with full manufacturer warranties plus its own 20-year quality guarantee, while concentrating internal engineering effort on application engineering, on-site execution, and after-sales support.

Commercially, MIESA operates an enterprise field sales motion supported by regional offices in Cartagena and Tarragona (Spain) and direct offices in Venezuela and Argentina, complemented by a distributor and representative network across the Iberian Peninsula and South America. Revenue is generated through three streams: one-time equipment sales, usage-based equipment rental (with a 24-hour delivery guarantee within Spain), and professional services for in-situ execution. Pricing is not publicly disclosed and is set per quote. The company markets primarily through technical content (blog, LinkedIn, YouTube, Facebook, Twitter), participation in industry events such as the EWJI annual congress, and direct contact. It maintains ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications audited by BM Trada (ENAC), and many of its represented products carry ATEX, TÜV, CE, and PED 97/23 EC certifications required for nuclear and hazardous-area work. The company is independently owned by founder and manager Emilio Keller Soria, with 11–50 employees.
