What Kelvin does
Kelvin Sp. z o.o. is a Bielsko-Biała, Poland-based engineering company founded in 1989 that delivers district heating, HVAC, and industrial heat recovery services to municipal utilities and industrial customers. The company operates through three divisions — TERNO (heating systems construction and modernization), Kelvin IT (digitalization software and thermohydraulic simulation), and Alukast (non-ferrous metal die-casting equipment) — providing an end-to-end offering from concept and design through equipment supply, construction, and software-based operational optimization. The Kelvin IT division is the technology core, offering offline and online digital twin software that performs hydraulic and thermodynamic simulation of district heating networks, plus three optimization modules (Temperature Optimizer, Pump Optimizer, Production Optimizer) that minimize heat distribution and electricity costs in real time.
The business model is project-based B2B engineering services sold through direct enterprise and municipal sales. Pricing is structured around design services (PLN 20,000–200,000) and execution services (PLN 200,000–10,000,000), typically under multi-year contracts that include warranty and post-warranty support. A notable differentiator is Kelvin's bundled advisory on Polish energy efficiency incentives, including White Certificate acquisition and NFOŚiGW EU funding applications — a regulatory navigation capability demonstrated by securing over PLN 900,000 in White Certificates for a single industrial customer (Teksid Iron Poland, Stellantis group) in 2023. Customer outcomes on flagship projects include PLN 3 million in annual savings, 9,000 MWh of recovered thermal power, and approximately 50% CO2 emissions reduction for the same client.
Kelvin maintains two physical offices (Bielsko-Biała headquarters and Kraków branch, opened 2015), employs 11–50 staff, and is privately held with no external institutional investment, no M&A activity, and no leadership changes disclosed. The company maintains a regional sales motion within Europe, supported by a Polish, English, and German multi-language website, content marketing through a knowledge base, and organic social presence on LinkedIn, Facebook, and YouTube.

Kelvin product offering
Product offeringCore offering
Kelvin is a multi-division engineering company that designs, builds, modernizes, and digitally optimizes district heating systems and industrial energy infrastructure. Through its TERNO division it provides energy efficiency services (heat recovery, cogeneration, industrial cooling, HVAC), design, construction, and supply; through its Kelvin IT division it sells proprietary district-heating software (offline/online simulation modules and optimization modules) and engineering consulting; and through its Alukast division it supplies non-ferrous metal die-casting technologies. Customers are predominantly industrial plants and municipal heating utilities.
Product overview
Kelvin is a multi-division engineering company offering a portfolio of products and services across three distinct divisions. The core technology offering is concentrated in the Kelvin IT division, which provides specialized software for district heating networks — including Offline and Online modeling modules, plus three optimization modules (Temperature Optimizer, Pump Optimizer, and Production Optimizer) — alongside engineering consulting and digitization services. The Kelvin TERNO division delivers a comprehensive suite of district heating and industrial services including energy efficiency (cogeneration, heat recovery, industrial cooling, HVAC), design and technical consulting, construction/modernization, and supply of materials and equipment. A third division, Kelvin Alukast, focuses on non-ferrous metal die-casting technologies. The IT software portfolio and TERNO service offerings are the primary product lines; Alukast operates as a separate product line. Together, the divisions form a vertically integrated offering from design and software optimization through to construction, supply, and operation of district heating systems.
