Volstad Maritime to Use EnwaMatic’s HVAC System

Volstad Maritime is a real front runner in using new environmentally proven technology and they have recently decided to change their engine and HVAC water treatment regime.

In order to have functional systems, it is very important to treat the water cooling in the engines and in the HVAC systems. The old fashion way to do this is to use a chemical mixture to avoid corrosion, scaling and biofilm(bacteria).

Volstad has discovered the Norwegian patented EnwaMatic® Technology when ordering the first ships in their latest series of new ships.

The instant that water enters the system it causes flash corrosion, and during operation it will form scaling, bacterial contamination and fouling. This has a significant impact on energy consumption, motor components and overall Life Cycle Cost (LCC). No more than 2 mm of rust can reduce heat transfer by 5% across component surfaces. Scale has an even more significant effect on the transfer efficiency with a small 0.5 mm layer generating as much as 4% in increased fuel consumption.

When specifying a water treatment regime consideration must be given to its efficiency, its whole life cycle cost, how easily it can be implemented and managed, and what potential risk it presents to personnel and the environment.

A major worry for ship owners has been the fact that whenever an engine cooling system or an HVAC system is drained, the water has to be treated as special waste since chemicals are being used to avoid corrosion, scaling and bacteria.

Traditionally, water treatment for HVAC and engine water is done by adding different types of chemicals to balance the water quality and in order to avoid corrosion damages. Doing so, however, can cause localised pitting and accelerate corrosion.

Contrary to this the EnwaMatic® technology is based on filtering and treating the water with minerals balancing, removing oxygen and neutralizing the water. The unit is fully automatic while it protects the engine or the HVAC system internals.

The EnwaMatic® Maritime water treatment unit combines reproducible principles of water chemistry with standard water treatment technologies. The unit provides effective dirt and air separation with environmentally sound water conditioning. It creates changes in key water parameters, such as pH, alkalinity and hardness, to elicit corrosion inhibition, control of scale formation and a biocidal effect.
