Hydr-Unit Premium Line

Summary

Product identification

The Hydro-Unit Premium Line is a pressure booster system available in several configurations:

• DOL CC: Fixed speed pressure booster system with Megacontrol pump control.
• VFD CM CC: Variable speed pressure booster system with Megacontrol pump control, frequency inverter in the control cabinet.
• VFD MM CC: Variable speed pressure booster system with Megacontrol pump control, frequency inverter mounted on the (IE5) motor.

These systems are designed for building services water supply applications.
