What RMT does

RMT (also known as Ferrotec-RMT, ООО «РМТ» / RMT Ltd.) is a Russian-based specialty manufacturer of thermoelectric coolers (Peltier modules) and thermoelectric generators, founded in 1994 and headquartered in Moscow. The company operates two production sites — pilot manufacturing at its Moscow headquarters (46 Varshavskoe Shosse) and mass production in Nizhny Novgorod (Larina str., 22 lit D4) — and is a subsidiary of Japan's Ferrotec Holding since 2020, having integrated with Ferrotec-Nord in 2022. RMT offers what it describes as the world's largest standard nomenclature of thermoelectric modules, spanning 3,500+ part numbers from 1×1 mm micromodules to 60×60 mm general-purpose modules, including multistage (up to 130°C differential), cycling-resistant, and thermoelectric generator variants, plus complete assemblies and supporting components.

Core technology is proprietary bismuth telluride (Bi-Te) thermoelectric material produced in-house, with patented processing methods (Parylene protective coating, Au80Sn20 paste-free assembly, 4-cascade heat-removing bridge design, and an internal thermoelectric module optimization algorithm dating to 2005). Adjacent capabilities include flux-free soldering, epoxy and conductive-glue bonding for PD/LD/MEMS/SMD components, hermetic sealing in inert environments, and production of Ge/Si/Sapphire/Beryllium windows with AR coating. Products are qualified to Telcordia GR-468-CORE, MIL-STD-883L, ISO 9001 (since 2003), ISO 14001 (since 2015), and RoHS (since 2006), with DAkkS international accreditation added in 2026.

RMT sells primarily through direct enterprise sales and a website with online product selection tools, supplemented by regional distributors in China (Xiamen Zibo Optoelectronic in Xiamen, Hantech Technology in Shenzhen/Hong Kong) and an exclusive Korean distributor (Sunflower Energy). Revenue is generated through hardware sales of thermoelectric modules, custom optoelectronic assembly services, and components (ceramic substrates, windows, packages, TEC controllers), serving telecom laser stabilization, photonics/photodetector cooling, medical/PCR, industrial laser cooling, aerospace/sensor stabilization, automotive LiDAR, consumer cooling, and IoT autonomous-power applications. Named aerospace customers include the IAS (Orsay) Mars program and Ben-Gurion Institute; the company states its products serve a significant portion of global fiber-optic communication channels and are used in space equipment across Russia, North America, and the EU.
