| '''Dosing Unit''' is meant to dose a chemical into water. The chemicals can be chlorine for fresh water systems, corrosion inhibitors for main engine cooling water, pH adjustment of fresh water etc.

|
| The unit consists of a dosing pump, a control cabinet, an injection valve and a container for the chemical. The container is equipped with a low-level alarm which stops the pump in case chemical runs out, a suction valve and a manual agitator. All components are mounted on a stable steel frame for easy installation.
| | '''Dosing Units''' are the result of meticulous design work: maximum attention has been paid to ease of use and reliability. The control unit is based on a microprocessor, which makes programming very flexible, and a motorised screw controlled by inverter, thus ensuring high performance. An important feature of this equipment is the ability to directly set the dosing percentage. It does not require maintenance and offers long-term reliability. |
| | |
| The most common application is that the dosing unit is being used to prechlorinate or pH-adjust fresh water, prechlorinate evaporated water or bunker water, on its way to fresh water holding tank, and to rechlorinate water before it is distributed. The prechlorination systems are normally controlled by flow meters in bunker water flow line and evaporated water flow line respectively. This ensures enough chlorine dosed into the actual water flow in the water line proportionately.
