Hadex Water Treatment for Clean Water

It is a legal requirement to keep your drinking water in good condition, but it is especially important in the shipping and offshore industry when you may have potable water stored for long periods of time. Hatenboer Water has been enabling people to do this since 1906, and their drinking water products are some of the most widely used marine supplies within maritime and offshore sectors. One of their most famous products is Hadex drinking water disinfectant. This innovative substance is just what you need to ensure that your potable water remains safe for consumption on board.
