Orion Machinery

What Orion Machinery does

Orion Machinery is a privately held Japanese industrial machinery manufacturer founded in 1946 in Nagano Prefecture, specializing in precision thermal management, vacuum, and air treatment equipment. The company develops, manufactures, and services precision air conditioners (PAP series) using its proprietary Heat Pump Balance Control technology, oil-free and dry vacuum pumps (KCM, KCE series), chillers, hydrogen station pre-cooling equipment, water electrolysis hydrogen generators, compressed air purification and temperature-control devices, jet heaters, dehumidification dryers, and automated dairy farming equipment. Core technology competencies span refrigeration/cold thermal technology, vacuum technology, collection/filtration technology, combustion technology, and temperature control technology, supported by a dedicated Technology Research Institute in Nagano and a Global Training Center. The company has won more than 25 Japanese national and regional awards, holds Japan's first dry pump (1965) and Japan's first milk cooling unit cooler (1960) as landmark innovations, and its PAP series has been recognized by the Ministry of Education Science and Technology Award.

The company operates 23 group companies (15 domestic, 8 overseas) with 2,433 consolidated employees as of March 2026, generating 650 billion yen in consolidated revenue. Manufacturing is conducted at four Japanese sites (Suzaka HQ, Chitose, Kosyoku/Chikumagawa, Tochigi) and three overseas sites (Shanghai since 2000, Thailand since 2012, plus India JVs in 2017 and 2026), with a North America Customer Support Center established in 2014. Revenue is generated primarily through hardware sales of industrial equipment (precision HVAC, vacuum, chillers, hydrogen, compressed air, heating) and dairy equipment, with a recurring maintenance, repair, and inspection service stream. Go-to-market is enterprise field sales through a direct sales force and an extensive distributor network across Japan, complemented by an online storefront (orion-netshop.com) and overseas subsidiaries serving the semiconductor, industrial manufacturing, dairy farming, and hydrogen infrastructure segments.

Customer segments are diverse and industrial in nature: semiconductor and LCD manufacturers (precision temperature and humidity control for cleanrooms), industrial manufacturers (data centers, automotive, pharmaceutical, laser, printing, scientific research), dairy farms (milking robots, feeding systems, barn environment control), and hydrogen station operators (pre-cool chillers and heat exchangers for fuel cell vehicle refueling). Pricing is custom-quotation-based tied to specifications, capacity, and customization, with multi-year contracts and after-sales maintenance. The company maintains ISO 9001 (since 1996) and ISO 14001 (since 2002) certifications across its factories.
