FATI

What FATI does

FATI (Fabbrica Apparecchiature Termoelettriche Industriali) is an Italian designer and manufacturer of industrial electric heating systems, founded in 1945 and headquartered in Cusago (Milano). The company produces flanged, threaded, and duct immersion heaters, electric heat exchangers, cartridge heaters, control panels, heating cables, convector heaters, transformers, and packaged process skids. Its product range spans power ratings from a few kW to over 8,000 kW and serves process heating for liquids, gases, vapors, and air. A core differentiator is the company's portfolio of ATEX/IECEx-certified explosion-proof products for Zone 1 and 2 hazardous areas (groups IIA, IIB, IIC; temperature classes T1-T6), alongside ISO 9001:2015 quality certification and API 614 compliance for certain cartridge heaters. FATI uses SOLIDWORKS Flow Simulation CFD tools for design validation and supports in-house engineering of custom configurations including exotic sheath materials (Inconel, Incoloy, Monel, Hastelloy, titanium) and flanges up to 60 inches per ANSI B 16.5.

FATI operates a direct sales-led go-to-market model with local representatives in more than 30 countries across Europe, North and South America, Asia, and North Africa, exporting more than 50% of production. Pricing is quote-based and project-driven, with multi-year contracts and full after-sales support including installation, commissioning, and scheduled maintenance. End-markets include oil & gas, petrochemical, chemical, industrial manufacturing, HVAC, galvanic/electroplating, and emerging alternative energy applications such as hydrogen fuel cells. As of the input data, FATI has been acquired by Thermon Group, a publicly listed global provider of thermal energy transfer solutions, and now operates as a Thermon subsidiary. The Cusago facility includes rooftop solar generation producing 150 MWh of electricity annually.
