Sinko Industries

What Sinko Industries does

Sinko Industries (新晃工業株式会社, SINKO INDUSTRIES LTD.) is a Japanese manufacturer of commercial and industrial air conditioning systems, founded in 1950 and headquartered in Osaka. The company designs and manufactures central air handling units (AHU), fan coil units (FCU), heat pump air conditioners, and specialized systems for clean rooms, data centers, and large spaces, with a self-described 'Air Design Company' positioning. SINKO's core technology is built around proprietary in-house components — aerofoil-blade plug fans, sirocco fans, coils, filters, humidifiers, and heat exchangers — produced in a made-to-order configuration through two domestic factories (Kanagawa, Okayama) and overseas plants in Shanghai and Taiwan. Differentiated technologies include UVC sterilization (Health Air Conditioning / 健康空調®), low-temperature (40–80°C) regeneration desiccant rotors, defrost rotation for heat pump systems, DC brushless motor FCU integration, dual-fan-motor redundancy (Relief Air AHU), and BACnet IP communication for building automation integration. The company also operates an in-house AMCA-certified fan testing laboratory at the Kanagawa Technical Center.

The business model is B2B enterprise equipment sales with custom one-piece-per-order design and manufacturing. SINKO engages building developers, construction firms, design offices, and equipment engineering companies from the planning stage, with sales supported by showrooms (SINKO AIR DESIGN STUDIO in Osaka, SINKO TECHNICAL CENTER in Kanagawa), the SINKO Direct online search/quotation platform, and international distributors serving 40+ countries. Customer segments are vertically organized around large building air conditioning, industrial and clean-room applications, data center cooling, HVAC renewal/retrofit, and individual heat pump systems for sports facilities and warehouses. Recurring revenue is generated through SINKO Atmos, a group company providing maintenance, inspection, degradation diagnosis, and renovation services, plus parts supply guaranteed for 5 years post-discontinuation. Disclosed FY2026 (ending March 2026) revenue was ¥59.3B with operating profit of ¥9.4B (~16% operating margin), and the company operates under the 'move.2027' medium-term plan with a 50% dividend payout target (DOE floor 3.5%) and a ¥10B treasury share repurchase program over FY2025–2029.
