What Isoterm Firm JSC does

AO Firma Izoterm (АО "Фирма Изотерм") is a Russian manufacturer of heating and cooling equipment founded in 1990 and headquartered at the Izhorsky Zavod plant in Kolpino, Saint Petersburg. The company's core business is the design and production of water-based heating convectors across three mounting formats — floor-level (Golfstream series), wall-mounted (Atoll, Koral, Izoterm, Izoterm-M, Ekoterm series), and floor-standing variants — supplemented by steel tubular radiators (Line series), aluminum panel radiators (Prime series), and specialty products such as facade, sill, baseboard, and bench convectors. The catalog spans 43 series and approximately 284 models, supporting over 1,400,000 configuration variations. Manufacturing is carried out at a single ISO 9001-certified facility in Kolpino, with the entire product line confirmed compliant with GOST standards in June 2026 and 'Made in Russia' certificates received in July 2026.

The company serves B2B and institutional customers across all major Russian federal districts (Northwestern, Central, Volga, Ural, Southern/North Caucasian, Siberia/Far East) plus CIS countries, with vertical segmentation covering residential complexes, administrative and business centers, retail and hotel complexes, sports halls and pools, theaters/museums, and educational institutions. Revenue is generated through direct regional sales of heating equipment, automation components (valves, fan motors, control units), and supporting services including BIM models, technical documentation, and 3D/CAD drawings. An adjacent specialty brand, Ekoterm Pro, markets ceiling radiant panels for large-height and large-area premises with claimed energy savings of up to 50%. The firm is privately held with no disclosed parent company, subsidiaries, or external funding, and is led by General Director Viktoriya Nesterova.
