Electro-Therm SAS

What Electro-Therm SAS does

Electro-Therm SAS is a French family-owned industrial company founded in 1972 in Lyon (headquartered in Bron, Auvergne-Rhône-Alpes) that designs, manufactures, and sells electric resistance heating elements and complete heating systems for industrial customers. The company's core technical offering spans more than 100 products organized across cartridge heaters, industrial immersion heaters, band heaters, tubular and finned elements, ATEX-certified explosion-proof heaters, electric heat-tracing cables, infrared emitters, flexible flat heaters, circulation and air-blow heaters, battery and convector units, and a specialized railway heating portfolio that includes the proprietary BluePoint smart switch-heating system (sensor and weather-forecast-driven regulation claiming up to 80% energy savings) and the BlueWire catenary/overhead-contact-line de-icing system (powered directly from 500–1200 VDC OCL).

The business sells through a direct regional field-sales model with commercial representatives present across multiple French regions, supplemented by attendance at major industrial trade shows (CFIA, SEPEM, InnoTrans, Sifer, Interclima, Petrochymia, FIP, Be Positive, Prod&Pack, SIRHA). Pricing is quote-based for both standard and custom-engineered solutions; the company describes itself as a "family business on a human scale" emphasizing direct customer access to technical sales staff. Customer demand is diversified across multiple verticals — food industry, packaging and packing, energy (including renewable), railway infrastructure and rolling stock, petrochemicals, plastics manufacturing, and general industries (petrochemicals, automobile) — each with distinct pain points around precision temperature control, energy efficiency, regulatory compliance, and safety in hazardous environments.

In October 2025 the company extended its product line by becoming the official exclusive French distributor of Heat Trace LTD heating cables and heat-tracing products, and in 2025 announced a doubling of its workshop and office space at the Bron site. The company is ISO 9001:2015 certified and maintains a broad ATEX certification footprint across multiple product categories, both of which underpin its ability to serve safety-critical and explosive-atmosphere customers. No revenue, parent company, institutional investment, or public-market information is disclosed.
