Dunham-Bush started operations in 1894 when two companies, C.A Dunham company and Bush Manufacturing company merged together and formed “Dunham-Bush”.

A factory was built in Morden, Great Britain to manufacturer air conditioning and heating products for the European market. As a part of the strategic expansion to bring the Dunham-Bush brand outside of the USA and into the international market, the factory was later moved to Havant, United Kingdom with larger manufacturing capabilities.

Dunham-Bush achieved a technological breakthrough and was the first company to develop and use screw compressor technology for air conditioning and refrigeration.

Dunham-Bush developed the single stage centrifugal compressor with large capacity range, reliable performances and superior efficiency.

Dunham-Bush built the new manufacturing plant in Yantai, China. The 20-acre state of the art manufacturing plant was a part of Dunham-Bush expansion, especially for the Asia market, resulting in the demand for lower manufacturing cost, enabling us to produce high efficiency and quality product at a competitive price.

Dunham-Bush built the second Asia manufacturing plant in Kajang, Malaysia. The manufacturing plant was built to cater to the needs of customers in South-East Asia, South Asia and Middle East Market. In addition, as part of Dunham-Bush strategic approach, the headquarters was transferred from the USA to Malaysia.

Continuous R&D with strong engineering and technical expertise resulted in new high efficiency dual stage centrifugal compressors which offers exceptional efficiency and suitable for high ambient conditions in the Middle east.
