Variable frequency drives for reverse osmosis pumps

The reverse osmosis system is used to purify contaminated water or desalinate sea water to make it fit for industrial or human use.
When used in reverse osmosis plants, robust Emotron drives made up of flexible, interchangeable building blocks (PEBBs) ensures a high operational efficiency and low repair requirements.

The reverse osmosis system at a glance

Reverse osmosis (RO) is a special type of filtration that uses a semi-permeable, thin membrane with pores small enough to pass pure water through while rejecting larger molecules such as dissolved salts (ions) and other impurities such as bacteria.

Flexible modular design for smart space solutions

Emotron drives are built up using an interchangeable scalable Power Electronic Building Block structure ideal for high pressure pump applications such as reverse osmosis. Each PEBB module has its own semiconductor fuse which limits possible damage to one module only.

High overload capacity

This unique PEBB technology is a modular approach to high power drives offering exceptional flexibility and redundancy. Higher overload capacity ensures that the requirements of high pressure pump applications are easily met.

Robust drives for high pressure pumps

Emotron FDU drives available in 400-690V are made in an exceptional electrical and mechanical robust design for reliable operations.

The compact IP20 drives can be built in cabinets to accommodate for the limited space available in RO plant containers.

World-renowned leader in high pressure pumps

When Pact Engineering was looking for a reliable supplier for drives for their high pressure pumps used in their RO plants, they turned to Emotron. Working with a world-renowned leader in high pressure pumps, a complete system was offered as per stringent specifications.
