During 2003/2004 Diamond H Controls has established a second manufacturing operation in China. The creation of DHC Asia HK Limited is a major milestone in the history of Diamond H and a springboard to renewed success in the future.

The site holds ISO, BEAB and QMS approvals and has the capability to produce all of the core products in the Diamond H range – Electric and Gas Thermostats, Gas Supervision Devices, Gas Solenoid Valves, Gas Control Valves and Energy Regulators.

In addition the site will be increasingly involved in Sub-Assembly production – utilising both Diamond H and bought in parts – to match the needs of the worldwide OEM market.
