Variable frequency drive
A variable frequency drive is used for adjusting a flow or pressure to the actual demand. It controls the frequency of the electrical power supplied to a pump or a fan. Significant power savings can be achieved when using a VFD.
Destructive force that relates to the incompressibility of water. The phenomenon often occurs when filling an empty pipe or quickly closing a valve. It often leads to pipe noise or even destruction of pipes, valves etc.
Water supply systems in zones
Systems divided into zones are used to gain optimum user comfort in water supply- and water distribution applications. These are typically found in high-rise buildings and hilly landscapes.
Water-brine cooled oil cooler
Water-brine cooled oil cooler is an application used to remove a part of the energy input to compress the refrigerant from suction to discharge pressure as well as mechanical friction.
