All the  advantages of built-in electronics

An inverter allows 4HS to:

• Change pump speed to maintain set-pressure regardless of water demand. Consequently the pump is operated only when and as needed without wasting energy, thereby extending pump life.
• Starts and stops pump gently, thus reducing peak absorption, mechanical stress.
• Protects pump and drive from overload, undervoltage, surges, dry running and any abnormal conditions.

Integrated on-board inverter avoids the use of expensive filters and shielded cables reducing electromagnetic emissions to a minimum.

4HS product range meets the needs of commercial and residential markets for water supply, water pressurisation and irrigation.
Compared to conventional solutions, 4HS offers:

• Energy-saving operation.
• Quick and simplified application.
• System reliability.

Construction characteristics and use of specific materials allow 4HS to be suitable for drinking water applications.
