Elta Fans ultra modern headquarters, Fareham, England.

For nearly thirty years now, Elta Fans technological advances in fan design and engineering have put us at the forefront of customers minds, providing them with a wide spectrum of products for a large variety of applications.
Established in 1974, Elta initially produced circulating fans for high temperature applications. As the business soon developed, Elta’s capabilities in fan design focused on supplying Original Equipment Manufacturers (OEM’s), the majority of applications for heat exchangers, engine room cooling, oil rigs and dry cleaning machinery. Expansion and growth came quickly, as Elta continued to match its capabilities, application knowledge and expertise in fan engineering, against it’s customer needs. So much so, Elta has established an enviable reputation for its innovation in axial flow fan technology, whilst also developing the worlds first adjustable pitch mixed flow impeller.
By 1996, following retirement of its founders, Elta Fans was acquired, becoming the principal company in the newly formed Elta Group. Remaining a privately owned company, substantial investment has supported Elta’s continued expansion on a worldwide scale.
Visitors to Elta Fans new ultra modern headquarters in Fareham, UK, will see evidence everywhere of the largest investment programme in the company’s history.
Within the domains of the air movement sector, Elta Fans products have evolved for building services applications, to air coolers and refrigeration, offshore and marine, to industrial processing, traction and other specialist markets.
