Hydrophore vessels

A stable water supply and economical, gentle handling of precious drinking water resources are the core benefits of potable water expansion vessels. The vessels save valuable drinking water. However, in a pressure boosting system the vessel stabilises also the pressure in the drinking water network. As there are no uniform standards, Hatenboer-Water provides a range of vessels that meet up the high offshore and maritime demands you need.

Kemper Valves

Water is distributed throughout the ship and is not only consumed by the crew, but also by water fed systems. Every time the water is used the risk of chemical/biological contamination of the complete system grows. Kemper regulation valves, backflow preventers and venturi are a basic safeguard of your water system. All Kemper valves are provided with all necessary permits. All components underlie the strictest requirements, which can only be guaranteed through the greatest possible quality assurance.
