About JOSUN
JIANGSU JOSUN AIR CONDITIONER CO., LTD was founded in 1985 and sits in the Taixing Economic Development Zone on the bank of the Yangtze River. The company designs, manufactures, sells and services environmental control systems — bringing product development, system integration and after-sales under one roof.
Its work covers ships, offshore wind, energy storage, data centres, chemicals, grain storage and pharmaceuticals. This site covers the marine and offshore side of that range: air conditioning, refrigeration, ventilation, dehumidification, and the cooling systems that go with dual-fuel, inert gas and battery-powered vessels.
Outside China the group has run a service centre in Singapore since 2006, and has since set up companies in Hong Kong, Denmark and South Korea.
This site is the English-language site for JIANGSU JOSUN AIR CONDITIONER CO., LTD. The company's Chinese site is at www.josun.cn, where the same product range is published in Chinese.
