Sustainable solutions

Sustainability is the cornerstone of our operations at Evac; our HEM fresh water generation and purification solutions offer environmental advantages by helping our customers generate fresh water from seawater, reducing their consumption of naturally available fresh water. Our fresh water treatment and sterilization solutions also remove the need for plastic bottles on yachts, helping to reduce the scourge of plastic pollution in our oceans.

Our history

Hydro Electrique Marine (HEM) began producing reverse osmosis desalinators and offering related services in Antibes, France in 1987.

In 1995, the company introduced a number of freshwater treatment systems including filtration, sterilization, and water softeners. Over the years, these products have been continuously improved and enhanced to ensure excellent performance and reliability.

In 2015, HEM was acquired by UK-based Cathelco Group, which specializes in ballast water management, marine growth prevention, and corrosion protection systems. In May 2018, Evac Group acquired Cathelco Group, including HEM and Echo Marine (a yacht service company located in Mallorca, Spain).

Today, HEM has a strong position within Evac Group as a brand with a reputation for world-class service and quality fresh water generation systems targeting the demanding yacht market.
