SIETAR ET VTI

What SIETAR ET VTI does

SIETAR & VTI is a French industrial services company founded in 2003 through the merger of SIETAR Technologies (established 1974) and VTI (established 1991), headquartered in Pluneret, Morbihan, Brittany. The company designs, fabricates, and installs stainless steel industrial piping, boiler-made equipment (pressure vessels, tanks, steam barrels, heat exchangers), thermal installations, and factory utilities (compressed air, industrial water, fluid distribution) for food, chemical, cosmetic, and environmental industry clients. Its core technology stack pairs CNC-controlled tube bending (LEONARD PICOT machine with PROTUBE FAO software) with robotic water jet cutting (ABB IRB 4400 handling tubes and ducts up to 1200 mm diameter and 6000 mm length), POLYSOUDE orbital robotic welding, and a patented industrial hot water storage solution; the firm describes itself as the only European industrial piping company systematically integrating CNC bending into production.

The business operates on a project-based, professional services revenue model: each engagement is scoped and quoted individually, combining workshop fabrication (including prefabricated skids integrating piping, valves, electrical, automation, and regulation) with on-site installation, extensions, renewals, and maintenance. The company is 100% owned by SPIE Group since August 2018, runs an ISO 9001-certified quality management system (since 2008), and serves a customer base concentrated among French dairy and food processors (Lactalis, Synutra, Candia, Entremont, SILL, Novandie, HCI, Les Maîtres Laitiers du Cotentin), with additional exposure to seafood (Cite Marine), bakery (Delifrance), cosmetics packaging (Albea), food-equipment OEM (Tetra Pak), power (EDF Optimal Solutions), and municipal environmental projects (Communauté Urbaine de Brest). Distribution is direct field sales within the Grand Ouest de France region, supplemented by engineering-firm partnerships such as Thebault Ingénierie for dairy plant constructions.
