5. SCALA1 twin booster system
TM075391
SCALA1 twin booster system
SCALA1 can be easily setup as a twin booster, in case
there is a need for a stand-by pump or higher flow
demand.
For this purpose, there is a dedicated accessory set that
includes:
•
base plate
• inlet and outlet manifolds with valves
• communication cable
• fixing screws.
In the twin setup, the two SCALA1 pumps communicate
together via a cable included in the accessory kit,
enabling optimum double-pump operation.
5.1 Features and benefits
The twin system has all the features and benefits of the
SCALA1 pump, along with the ability to handle increased
flow demand.
5.1.1 Easy installation
SCALA1 twin booster can be quickly installed. After the
pumps are mounted on the base plate and connected with
a cable and manifolds, it is only a matter of connecting to
the pipe system.
Once the system is primed, it is ready to deliver water
.
5.1.2 Alternation
Once the communication cable is connected and the
system powered on, the pumps are automatically
assigned a priority at the start.
Alternation determines when the pumps will switch priority
in starting, enabling equal use during operation lifetime.
Grundfos GO Remote allows selecting the following
options:
•
alternate on runtime
• alternate on the number of starts.
Alternate on runtime
Pump 1 will be the first to start until it accumulates the
defined number of running hours. After that, Pump 2 will
start first.
Alternate on number of starts
Pump 1 will be the first to start until it accumulates the
defined number of starts. After that, Pump 2 will start first.
5.1.3 Grundfos GO Remote enabled
SCALA1 twin booster system can be connected to
Grundfos GO Remote via Bluetooth communication to be
able to adjust the system parameters to specific user
needs.
5.2 Protection features
SCALA1 twin booster has all the protective functions of
the SCALA1 pump.
Dry-run protection will stop each pump separately
, while
the anti-cycling protection and maximum runtime
protection will stop the system.
5.3 Operation modes
5.3.1 Duty/Assist
In Duty/Assist, both pumps can run at the same time,
delivering more flow on the outlet side.
If one pump is unable to meet the demand, the second
pump will start up.
5.3.2 Duty/Standby
In this mode, only one pump will run at a time, while the
other pump will remain as a standby pump.
Based on alternation settings, the pumps will switch
priority in starting.
