Frequency variator for electric pumps

It is an electronic device for controlling pumping systems and their protection, changing the frequency of the current supplying the motors. It can be used with any commercially available pumps to maintain a constant level of the set parameter (pressure, flow, fluid temperature, etc.) at changing working conditions. This allows the pump to be used necessary, significantly saving energy, with an increase in equipment reliability.

Purpose

• Domestic and industrial water supply systems;
• Irrigation;
• Heating and air conditioning;
• Filtration and pressure washing.

Design features

• Saving energy and reducing costs;
• Easy to install, lower overall costs;
• Increased system resource;
• Increased reliability.
