Energy efficiency means using savings potentials to the full

Halved electricity costs are now standard
because energy-efficient action is our goal

In the future, the availability of energy resources is the most urgent issue facing humanity. Currently, many companies are burdened by a sharp rise in energy costs. In Germany, typical costs for industrial electricity in 2021 were around €0.21/kWh - in July 2022 these climbed to over €0.40/kWh. Energy prices are likely to increase further in the coming years due to the uncertain geopolitical situation.

The only way out of the price spiral is to continuously minimise energy consumption. To reduce your electricity consumption, we offer optimised reverse osmosis systems with variable-speed drive (VSD, abbreviated FU in German) as standard equipment. In this way, you can significantly reduce your electricity costs, remain competitive by saving energy and at the same time treat water sustainably.

Would you drive your car at full throttle all the time and control the speed by applying the brakes?
Then why do you do that with a reverse osmosis unit?

Halved electricity costs through smart pump control lead to even faster amortisation

The use of variable-speed drive pumps (VSD / FU pumps) reduces the power consumption of our reverse osmosis systems by 30 to over 50 %. This allows the additional costs for the VSD pump to be recovered within a few months. Calculated over the lifetime of the plant, a variable-speed drive pump saves a multiple of the total RO unit costs.

Efficient thanks to VSD (variable-speed drive) pump

In our revised UO-D FU and UO-D AS/FU series, the high-pressure pumps are equipped with frequency converters (variable-speed drive) as standard. This reduces the power consumption of the system by approx. 30 - 50 %. The savings in electricity costs over the lifetime of the system amount to a multiple of the system costs.

Advantages of the systems with VSD pumps

  • Energy saving of 30 - 50 % or more
  • Amortisation of the frequency converter often after less than one year
  • Permeate production is kept constant regardless of operating pressure
  • Gentle start-up protects the technology and extends the service life
  • Particularly quiet operation of the reverse osmosis system

Do you also want to reduce water costs?
Our RO units with integrated concentrate stage are the solution.

Our UO-S7 KR/FU series is particularly water-saving. An integrated concentrate stage saves 50 % of the waste water. This allows you to achieve a permeate yield of up to 90 %.
