BWT Energy Saver variable frequency drive for pumps

BWT Energy Saver variable-frequency drive

The BWT Energy Saver variable-frequency drive is designed to optimize the operation of single-phase pool pumps, allowing their speed to be adjusted and modulated for significant energy savings. Its technology enables the selection of different speed ranges and time schedules, reducing electricity consumption without compromising the effectiveness of the filtration system. 

The unit features a clear, easy-to-use display showing the selected speeds, instantaneous consumption, and operating modes. It includes three preset modes —Day, Night, and Backwash— each configured with specific speed ranges that can be adjusted precisely. 

It must be installed indoors, in a ventilated and protected environment, at temperatures between -10 and +40 °C, and always with an RCD ≤ 30 mA to ensure electrical safety. The drive features protection against overheating, overcurrent, and other conditions that protect both the equipment and the connected pump. 

Its operating range covers speeds between 1200 and 2900 rpm, allowing precise adjustment in 50 rpm increments. Its maximum output power is 2.2 kW, and it supports pumps of up to 12 A. 

It is an ideal solution for modernizing traditional filtration systems, reducing annual energy costs by up to 80%, and improving the pool’s hydraulic performance, especially in installations that operate for many hours a day.
