What Ergotem does

Ergotem S.A. is a Greek industrial EPC (Engineering, Procurement and Construction) contractor established in 1991 and headquartered in Mandra, Attica, Greece. The company delivers complex engineering projects across seven verticals — Energy, Oil & Gas, Environmental, Industrial, Defense, Mining and Civil Works — serving enterprise and government customers such as Public Power Corporation (PPC), EYDAP, Hellenic Petroleum, TITAN Cement, ELVAL, NAVFAC/US Navy, NATO and various Greek municipal utilities. Its core product set includes full EPC delivery of power generation and processing plants, fuel storage tank farms (with more than 1 million m³ of cumulative installed storage), oil & gas processing and pipeline systems, district heating networks, flue gas cleaning (NOx/SOx) systems, wastewater treatment plants, defense fuel and electrical infrastructure, mining material handling systems and civil works.

The company operates a 10,000 m² covered in-house manufacturing plant equipped with heavy fabrication tooling, including a DAVI MCB K30 4-roll CNC plate rolling machine, and is one of very few Greek firms certified to ASME S, U and U2 stamps, the National Board R stamp, AQAP 2110 (NATO) and EN 1090-1 EXC4. A proprietary 'Jack-up' storage tank erection method reduces tank construction time by 40% and is highlighted as a technical differentiator. The business model is project-based B2B EPC contracting (one-time project awards) with a growing multi-year services line (notably the €210 million Psyttaleia wastewater treatment O&M contract with EYDAP), targeting large industrial and government customers in Greece and selected international markets including Romania, Germany, Cyprus, Bahrain and Kosovo. Founder and CEO Sakellios Dimitris leads the company, which employs more than 200 people.
