About HEM

Leading the way in water treatment

Hydro Electrique Marine (HEM) has built a reputation as Europe’s premier manufacturer of desalinators and water treatment systems for luxury yachts.

In May 2018, HEM became part of the Evac Group when Cathelco its former owner, was acquired by the world leading Finnish-based provider of integrated water and waste management systems.

This brings together a comprehensive range of products and unrivalled expertise in almost every aspect of water treatment and corrosion protection in the marine environment.

Based in Antibes, HEM began producing reverse osmosis desalinators in 1987. The current range of units covers all the requirements from small, cost effective systems for smaller yachts to the largest ultra-rugged duplex units capable of sustained output under continuous operation. Over the years, HEM have installed more than 4,400 desalinators providing enormous experience in this field.

Beginning in 1995, the company introduced a number of fresh water treatment systems including filtration, sterilisation and water softeners. Over the years, these products have been continuously improved and enhanced to provide excellent performance and reliability.

Combining expertise

Cathelco offers a portfolio of products that include marine growth prevention systems (MGPS) which prevent blockages caused by barnacles and mussels in engine cooling lines. They also provide ICCP hull protection equipment to safeguard steel and aluminium hulls. More recently they have produced a mini ballast water treatment (BWT) system specifically designed for superyachts which is being marketed under the Evac Evolution brand name.

Evac can provide bespoke solutions for numerous applications in the superyacht industry including toilets in customised colours and shapes. They also offer vacuum collection systems for toilets and food waste, plus waste water treatment systems. In addition, they produce equipment for reducing the volume of recyclable and non-cyclable dry waste on board luxury yachts.
