NSC..H SERIES
(e-NSC WITH HYDROVAR)
Background and context
In all areas of application, such as building services,
industry, agriculture and air-handling, the demand for
intelligent pumping systems is constantly growing.
There are many advantages: reduced cost for pump life
cycle, lower environmental impact, longer lifetime of
pipes and unions. That’s why we have developed the
NSC..H: an intelligent pumping system which assures
high level performance with energy consumption
tailored to demand.
Benefits of NSC with HYDROVAR
Saving: NSC..H transforms NSC pumps into variable
speed intelligent pumping systems. Thanks to the
HYDROVAR system, the speed of each pump varies so
as to maintain a constant flow or pressure or differential
pressure. The pump only receives the energy required,
thus allowing considerable savings, especially for those
systems in which demands varies during the day.
Easy installation and space-saving: NSC..H saves
time and space during installation. Installed directly on
the motor (up to 22 kW), which cools it down, and does
not require a further control panel. , only fuses on the
supply line (will depend upon any local electrical installation
regulations). The wall-mounted HYDROVAR version is
available for higher power outputs (up to 45 kW).
Standard motors: NSC..H models are fitted with
three-phase standard TEFC motors with insulation class
155 (F).
Special features / benefits
There is no need for additional pressure
sensors: NSC..H are fitted with a pressure transmitter
or differential pressure transmitters, depending on the
application.
• There is no need for special pumps or
motors.
There is no need for bypass or safety
systems: with HYDROVAR the pump immediately
switches off when demand drops to zero or when it
exceeds maximum pump capacity. This makes it
unnecessary to install additional safety devices.
• Anti-condensation device: all units are fitted
with anti-condensation devices which switch on when
the pump is in standby in order to prevent condensation
forming in the unit.
