SAN Electro Heat

What SAN Electro Heat does

SAN Electro Heat a/s is a Danish private limited company founded in 1950 and headquartered in Græsted, 55 km north of Copenhagen, operating as a subsidiary of the publicly-listed Swedish NIBE Group through the NIBE Element Railway Solutions cooperation. The company designs and manufactures electric heating solutions across two principal business areas: railway infrastructure de-icing and industrial process heating, with all BluePoint heating elements produced at its Danish factory.

The core railway offering is the BluePoint intelligent points heating system, which uses weather forecasting combined with local weather station inputs (rail temperature, air temperature, snow precipitation, wind speed) to modulate switch heating and deliver 40-80% energy savings versus traditional constant-heating systems. BluePoint is complemented by BlueWire contact wire de-icing for trams, light rail, and trolleybuses, plus a component portfolio covering heating elements with proprietary double-insulation layer technology (25-30+ year lifespan), control cubicles with 4G connectivity, safety transformers, weather stations, and a cloud or on-premises SCADA supervision software. On the industrial side, SAN supplies cartridge heaters, immersion heaters (including ceramic variants), closed coil heaters for spray drying, inline and flange heaters, spiral and square duct heaters up to 750°C, self-regulating and constant-wattage heating cables, industrial radiators, junction boxes, load resistors up to 1.5MW, thermostats, and ATEX-certified equipment for explosive environments. The company reports 500,000+ heating element installations globally across Europe, North America, Canada, Japan, and Australia.

The business operates a direct enterprise sales motion with dedicated Railway and Industrial Heating sales teams, supported by an online Heating Solution Designer quote tool, presence at industry events (Innotrans24, Hydrogen Tech Expo, MTI Japan 2025), and distribution partnerships notably with Mitsui & Co. in Japan and Vossloh Nordic Switch Systems in Sweden. Revenue is generated through quote-based hardware sales, turnkey project delivery, and bespoke custom engineering at the Danish facility, with multi-year contract pricing and named reference customers including Magdeburger Verkehrsbetriebe (Germany, ~300 switches), Helsingør/Elsinore Station (Denmark, 41 switches), Lokaltog/Maarum Station (Denmark), Japan Railway Construction at Takayama, Vossloh Nordic depots in Sweden, plus industrial customers EREMA (plastic recycling), SiccaDania (food/spray drying), Australian gold mining, and an unnamed Danish pharmaceutical manufacturer. SAN is ISO 9001/14001/45001 certified by Bureau Veritas and RISQS-approved for UK railway sector supply, with 101-250 employees and no disclosed revenue.
