Opür, founded at Milan in 1976 as one man business, was transformed in the very early years into a joint-stock company, maintaining its hallmark as dynamic and continually evolving company.

Since 1998 it has worked at the new headquarters at Grassobbio - Bergamo on a site of 2000 square metres, 1200 of which are covered. This facility is characterised by functionality and comfort, and can accomodate constant future developement.

Since January 2000, Opur has been certified according to the UNI-EN ISO 9002 standards.
Opur chiefly servers the wholesale market for heating and plumbing materials and in this context has specialised over time in creating equipment for treating primary water sources, privileging the civil sector.
The production range includes, filters, polyphosphate proportional metering devices, water softners, UV sterilisers and all the main devices to satisfy the requirements of the final user.
The evolution of the market and the quality of the products created has permitted Opur to extend its sales also to other water treatment copmpanies, bycustomising the individual pieces of equipment.

Today, Opur is present with its own products in Switzerland, France, Austria, Belgium, Croatia, Sweden, Norway, Greece, Tunisia, Turkey and Kuwait.
