KALFRISA

What KALFRISA does

KALFRISA S.A.U. is a privately-held Spanish industrial equipment manufacturer founded in 1965 and headquartered in Zaragoza, Spain, specializing in custom-engineered thermal and environmental solutions for industrial clients. The company organizes its offering around four core product families: heat recovery systems (convection, compact, and radiation recuperators), industrial heaters (modular/preheaters, start-up heaters, and compact VT/VK/VQ units), gas cleaning equipment (regenerative and recuperative thermal oxidizers plus complementary filtration systems), and waste valorization equipment (continuous KR rotary kilns, batch ROT kilns, and KL/KT/KP/SJ static furnaces). Notable technical performance includes >99% VOC destruction efficiency on RTOs (≥95% thermal recovery), fuel savings up to 40% via radiation recuperators, air preheating to 700°C, and emerging capabilities in hydrogen combustion (up to 100% H2) and electrified thermal equipment via the e-KM and DESCARB-e initiatives. Underlying technology is increasingly augmented by digital twins, the K-Connect remote monitoring platform, and predictive maintenance analytics developed through consortia with University of Zaragoza, AIMEN, and CLENAR.

The business model is enterprise project-based with three revenue streams: (1) one-time sale of custom-engineered capital equipment, (2) recurring technical services through the KALFRISA Service division covering installation, commissioning, preventive/corrective maintenance, retrofit, and digitization, and (3) spare parts supply. Pricing is fully quote-based with multi-year contracts, and no public pricing tiers exist. Go-to-market is enterprise field sales with wholly-owned subsidiaries in Poland and India, strategic alliances with Cabieses SAC (Peru/Latin America) and MEW India, and a network of commercial agents worldwide. Customers span metallurgy (ArcelorMittal, JSW Steel, Jindal Steel, SMS group, Tenova, Danieli, Fives), oil & gas (Total Petrochemical), mining (Glencore, Freeport-McMoRan, Metso, Boliden), waste management (FCC, Cogersa, PreZero), food (Nestlé, Lactalis), pharmaceuticals (Abbott), automotive (Stellantis), and paper (SAICA), with K-Connect and cremation products (KM, e-KM, KM-H2) extending service reach and product surface.
