1. Featuring of variable speed control by inverter

Ebara-Booster-UN-FSAVariable speed drives are used since they can adjust the
motor’s power to fit specific needs, resulting in reduced
energy consumption and in increased savings.

2. Constant estimated terminal pressure control

The controller provides CETP (Constant estimated
Terminal Pressure) control that adjusts pump discharge
pressure in relation to pressure loss caused by pipe
resistance according to water flow. Thus, it can hold
down electric power consumption compared to constant
discharge pressure control with variable speed operation


3. Stable water supply

Pumps are in parallel operation for high demand and In
the event of pump/inverter fault, the controller
automatically activates another pump to assure water
supply without stopping system operation.


4. Compact layout

Ebara-Booster-UN2SLayout is very compact. All components are integrated on a
rugged steel base. It is ready for use by only connecting
with supply piping and to the power source. It occupies
lesser space and requires easier installation than
conventional units.

5. Extend the life of pump

Pumps are operation in automatic alternate parallel to
extend the life of the pumps.

6. Simple and compact inner control panel

Simple wiring by using RS485 digital communication can
reduce control panel dimension to be a compact design.
