Cooling tower fans can be intelligently controlled by MPC controllers. The cooling tower with all its devices can be run with the pump controller without the need of another controller. Differential temperature control (according to return temperature) based on RPI+T sensors can significantly reduce OPEX. Onsite chlorine dioxide production will eliminate biofilm / legionella risk, improving the safety and efficiency of the cooling tower.

Grundfos iSOLUTIONS (DID + DDA) can automate the blowdown process, which leads to lower OPEX through less water and energy consumption. When biocides reach a defined lower threshold, the DDAautomatically and accurately adjusts the dosing rate with up to 75 % chemical savings. For scaling and fouling control the SMART Digital DDA with DDA can maintain a fixed flow and send alarms in case of e.g. low amount of chemicals. Chemical cost can be reduced.

1. Endsuction close coupled single-stage pumps - NBG/NBGE
Close-coupled pumps according to ISO 2858. Flanges are PN 16 with dimensions according to AS2129 table E. The pump has an axial suction port, radial discharge port, horizontal shaft and a back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbing the pump housing or pipework.

2. Endsuction close coupled single-stage pumps - NB/NBE
End-suction close-coupled pumps according to EN 733. The pump has an axial suction port, radial discharge port, horizontal shaft and a back pull-out design enabling removal of the motor, motor stool, cover and impeller without disturbing the pump housing or pipework.

3. Endsuction long coupled single-stage pumps - NK/NKE
Standard pumps according to EN 733. The pump has an axial suction port, a radial discharge port and horizontal shaft. It is of the back pull-out design enabling removal of the coupling, bearing bracket and impeller without disturbing the motor, pump housing or pipework.

4. Inline single-stage pumps - TP/TPE, TPD/TPED
Grundfos TP/TPE pumps are single-stage, close-coupled in-line centrifugal pumps with mechanical shaft seal and primely for applications such as heating/cooling/district energy. TPD/TPDE pumps are the twin-head version.

5. Horizontal splitcase pumps - LS
Grundfos LS is a horizontal, single-stage or double-stages, between bearings, split case pump. The axially split design allows easy removal of the top casing and access to the pump components without disturbing the motor or pipe work.

6. Immersible Pumps - MTR/MTRE
Vertical multistage centrifugal pump designed for tank top mounting and for pumping of cooling lubricants and cutting oils for machine tools, cooling applications, industrial liquid transfer and similar applications.

7. Digital Dosing Pumps - SMART Digital S/XL
SMART Digital diaphragm dosing pump with powerful variable-speed stepper motor (S) or powerful PMS (Permanent Magnet Synchronous) motor (XL) and FlowControl system to automatically detect malfunctions. High-end solution for complex and demanding applications with turn-down ratio up to 1:3000.
