Founded in 1985, Marioff is a leading provider of water mist fire protection on land and at sea. Our HI-FOG® Water Mist Fire Protection System is installed on almost every large cruise ship in the world. On land, HI-FOG® protects many structures such as tunnels, stations, hotels, energy facilities, heritage buildings, data centres and hospitals.

Headquartered in Vantaa, Finland, Marioff employs a skilled team of fire protection, mechanical, hydraulic and electrical engineers. This core group supports a global network of subsidiaries and agents, providing installation and commissioning assistance as well as service and maintenance backup.

HI-FOG® is the fire protection technology of choice across a diverse range of applications, backed by a dedicated team whose one aim is to provide customer satisfaction.

Marioff is a global company, part of UTC Fire & Security, a division of United Technologies Corporation (UTC). UTC is the parent of companies such as Pratt & Whitney, Otis, Sikorsky Helicopter and Carrier.

Marioff was founded in 1985 with pure entrepreneurial spirit and a motivating mission: protect people, property and business from fire, on land and at sea. The spirit lives on in a story of continuous growth. Marioff is today the world's leading supplier of water mist fire protection systems.

The company's background in marine and offshore high-pressure hydraulics (hence the name, MARIne and OFFshore) led to the development of a fire protection technology using the best attributes of a truly environmentally benign agent: water. Since its launch in 1991, HI-FOG® has earned a reputation for superior fire suppression performance, becoming the standard for water mist fire protection.

Key to this success has been the company's extensive research and development program carried out with leading independent authorities and fire testing laboratories. In 1992 Marioff received the prestigious Seatrade Safety at Sea Award, and the President of Finland presented the Innovation in Finland award in 1995.

Marioff’s greatest reward is the growing list of fires suppressed or extinguished by HI-FOG®, both at sea and on land. Already a trusted solution at sea, HI-FOG® is becoming increasingly important on land. With a growing number of protected installations, the range of both marine and offshore applications of HI-FOG® continues to expand.

In September of 2007 Marioff was acquired by UTC Fire & Security, marking the beginning of a new era in its history.
