WATER / WASTEWATER

Saving energy and equipment

This sewage treatment plant uses Emotron AC drives and softstarters to control pumps, blowers and mixers, and shaft power monitors to protect sludge scrapers and screw conveyors. The result is more reliable control and energy and maintenance savings.

PROCESS INDUSTRY

Great energy savings from speed control

This process industry saves 25,000 euros each year by speed controlling one of its fans. Emotron AC drives are used in several electric motor drives, including pumps, fans, mixers, mills and centrifuges. Major benefits are energy savings and a reduced wear.

SAWMILLS

Increased operational efficiency

When this sawmill invested in a new debarking line, CG products were chosen to control and monitor the heavier operations. Reliable operation, short braking times and a high level of user-friendliness are considered the greatest benefits.

PUMPS

Pumping twice the amount while saving energy

When the process control of this pumping station was automated, an Emotron AC drive for 690 V was part of a solution. The customer now benefits from double the pumping capacity, energy savings, improved user-friendliness and low harmonic distortions.

FANS

Simplified fan control and lower costs

The installation of Emotron AC drives in the grain handling of this food and agricultural industry, resulted in simplified control and reduced operating costs. Demands were high for both product performance and service level when choosing a supplier.

CRANES

Synchronized crane wheels reduce wear

The retrofit of this portal crane involved replacing the controls as well as the drive motors. CG provided a complete solution which requires less maintenance thanks to minimal wheel wear.

CENTRIFUGES

Energy-efficient centrifuges

When this treatment plant invested in new decanter centrifuges for dewatering sludge, Emotron AC drives were chosen for control. The energy generated by the braking motor is now re-used by the driving motor.

LIFTS

Top level lift control via a 220 metre cable

One of the difficulties when modernizing this lift was the 220 metre cable connecting the motor and the converter. What’s more, the client wished to keep the original DC motor. The lift is now up and running, taking visitors up the tower for a dizzying view.
