Enwa Water Technology is among the leading manufacturers of water treatment equipment for the maritime and offshore industry. We manufacture and supply a wide range of freshwater maker systems (RO) together with pre- and post-treatment for potable and technical water.

Water conditioner for the maritime, oil and gas markets

Enwa is the manufacturer of the patented, chemical-free water conditioner, EnwaMatic® Maritime (EMM), for freshwater based, closed loop, cooling and heating systems for engines and HVAC systems. The EMM is an environmentally friendly and chemical-free automatic unit that inhibits corrosion, control scaling, filter water to less than 5 microns, restricts bacteria growth and removes sludge, gas and oxygen from the water circuit. This is achieved by treating the water in a side stream filter regulating the water pH, alkalinity and hardness.

Environmentally friendly and self-contained, EMM does not require the use of hazardous chemicals or the critical exposure of employees during service and maintenance work. This has an obvious positive effect on both the environment and the HSE conditions for the employees operating and performing maintenance. There is also a financial up side as the requirements for chemicals are removed, and as a result of this the maintenance requirements are reduced significantly. The EMM is fully automatic and requires only minimal maintenance.

Bacterial barrier water treatment system

Enwa also manufactures the patented chemical-free bacteriological barrier Enwa Bin-X®. The Enwa Bin-X® is a patented cost-effective water treatment system used for removal of particles and bacteria such as Legionella and E-coli from potable and drinking water, offering maximum security against such epidemics. With the Enwa Bin-X® this can be achieved with a moderate level of investment.

ENWA supplies a wide range of environmentally friendly RO (Reverse Osmosis) and freshwater maker systems for the maritime oil and gas industry.
