The division was formed in 2007 with the acquisition of Water Mist Engineering AS (WME).
WME designs and assembles a full range of active fire fighting systems, such as low pressure water mist, deluge, sprinkler, etc. Each system is tailored to match the individual protection requirements. WME is also heavily involved in research and development of water mist nozzles and systems.

In 2008 the division expanded with the acquisition of ETech Process AS and Fire Eater A/S.

In 2009 ETech Process AS merged with Water Mist Engieering AS and the brand “ETech” became a part of the product line in the Extinguishing solutions business area.

WME manufactures on-site nitrogen generation systems utilizing membrane air separation technology. These nitrogen generation systems are used for inerting, blanketing, and purging of chemicals and other cargos. 
ETech membrane modules contain thousands of hair-like membranes that collectively separate large amounts of high purity, dry nitrogen directly from compressed air, which may be applied to prevent degradation of cargo sensitive to oxygen, moisture or combustion by-products. These systems are also ideal as non-freezing, non-corrosive instrument gas, and for drying of void spaces such as cofferdams.

The company’s emphasis is on in-house development of products based on environmental technology. Through the years, the company has developed a range of process products and systems, mainly within water and air/gas separation.
ETech holds numerous references within marine and offshore installations, both internationally and within the Norwegian continental shelf of the North Sea. The first nitrogen generator unit was delivered in year 2000 to ExxonMobil. Subsequently the company has moved into the maritime ship building industry, with the supply of nitrogen generators, based on membrane technology. For maritime references ETech has been a major supplier worldwide with the new ENG series.
