Setrab

What Setrab does

Setrab AB is a Swedish manufacturer of high-performance aluminum heat exchangers and cooling solutions, founded in 1968 in Malmö and operating since 2019 as an independent subsidiary within the Zhejiang Yinlun Co. Ltd. group (Shenzhen-listed). The company designs and manufactures bespoke oil and water coolers using Controlled Atmosphere Brazing (Nocolok process, in use since 1979), supported by proprietary simulation workflows (Kuli, FEM, CFD) and 100% automated helium-based leak and pressure testing of finished coolers. Product lines span oil and water coolers (STD, SLM, COM, CON LT, LT, WCAC Twin Core, PHE), battery thermal management components (Battery Cooling Plates, Battery Cooling Tubes, Dedicated Cooler Packs), and liquid chillers (PolarC 2.0–4.5kW for EV charging, PolarS 5–60kW for Battery Energy Storage Systems). A Proline sub-brand serves motorsport and aftermarket customers through a 12-country distributor network, while OEM revenue is generated via direct B2B sales to premium automotive manufacturers (Aston Martin, Ferrari, Lamborghini, McLaren, Bentley, Mercedes-AMG, BMW M, Audi, JLR), commercial vehicle OEMs (Scania, Volvo, Husqvarna), and industrial/medical equipment producers (Siemens, Philips, Hydac, Laird).

Operations are dual-sited: R&D, prototyping, customer engineering, and small-volume series in Malmö, Sweden, with high-volume series production at a 4,500m² facility in Karlino, Poland (Yinlun Setrab Poland Sp. z o.o., extended in 2024). Both entities hold IATF 16949 and ISO 9001 certifications, with the Polish site additionally ISO 14001 certified by Bureau Veritas. Combined headcount is approximately 125 employees (~55 in Sweden, ~70 in Poland). Business model is a hybrid of long-cycle bespoke OEM contracts (negotiated multi-year, project-based pricing) for thermal management systems and off-the-shelf aftermarket distribution through Proline distributors, with a 2025 strategic pivot emphasizing battery thermal management for EV charging and grid-scale BESS.
