What Koja does

Koja is a Finnish family-owned industrial engineering company, founded in 1935 in Tampere and controlled by the Aalto family for four generations, that designs and manufactures intelligent air handling solutions (HVAC) and industrial process fans across three business segments: Marine (HVAC systems for cruise ships and vessels, including named deployments for Royal Caribbean, Carnival, and Celebrity Cruises), Buildings (air handling units, energy optimization platforms, and lifecycle services for hospitals, offices, and commercial real estate such as Oulu University Hospital and The Node in Tampere), and Industry (engineered-to-order process fans for energy production, pulp and paper, metals and mining, cement, and glass tempering, with nearly 50,000 fans delivered cumulatively).

The core technology portfolio includes the Future® modular air handling unit series (32 machine sizes, airflow 0.2–40 m³/s, with rotor, counterflow, liquid circulation, and proprietary Netto+® heat recovery), the ECOFAN® process fan range (axial and centrifugal, 0.1–800 m³/s, pressures up to 45 kPa single stage), the Wave Solution integrated building energy platform (Wave Selector, Wave System, Wave Evidencer cloud analytics, reportedly reducing purchased energy by up to 80%), the KojaControl automation system (10.1" touchscreen, Modbus RTU/TCP/IP, BACnet, energy monitoring, 5-year remote support), carbon fiber impeller technology for cyclical industrial processes, and the Industrial Next turnkey service. The company holds ISO 9001, 14001, 45001, 50001, and 3834-2 certifications, plus EPD declarations for Future® units, and operates an R&D Center in Tampere with real-condition testing and FAT capabilities.

The business model is engineered-to-order and project-based, with direct enterprise sales to shipyards, cruise lines, building developers, hospitals, and industrial plant operators across 90+ countries. Wholly-owned subsidiaries include Koja Oy (Finland), Koja USA Inc. (Miami, since 2016), Koja GmbH (Germany, since 2024), and Chiller Oy (heat pumps and cooling). Revenue is generated through one-time equipment sales, recurring lifecycle services and spare parts, and turnkey Industrial Next integrated solutions.
