WATER CONNECTIONS
HYDROPACK - OPTIONAL
The equipment of refrigerant groups with the Hydropack
accessory allows the supply of the necessary rate/head with
different solutions:
HYDROPACK with 1 pump
for low-power units you can choose the basic solution with 1
pump.
HYDROPACK with 1 pump + 1 standby
also for low-power units you can include a second pump for
complete reliability. If one pump shuts down, the other one
automatically starts up and the unit control signals the
shutdown of the pump that is out of order. The micro-
processor automatically balances the hours of operation of
both pumps
HYDROPACK with 2 pumps
Per less power units, the standard solution with 2 pumps can
be chosen. If a pump gets blocked, the unit will go on working
till about 80% of the charge. This solution is more reliable than
the traditional ones with a single great power pump.
HYDROPACK with 2 pumps + 1 stand-by,
2 reserve pump can be foreseen for assuring a total reliability.
So the design water rate is assured (in fact, in the event of a
failure, the reserve pump is automatically activated and the
unit control signals if the broken pump is blocked).
HYDROPACK with 3 pumps
for units of greater power; with the solution of 3 pumps which
are always activated, the possible blocking of a pump always
assures the regular working up to 80% of the charge (always
with the signalization of the blocking). In this case, it is
possible, upon request, to supply a reserve pump (not
connected). The replacement is performed in few minutes
time, thanks to the simple foreseen connections.
The modular pumping system allows for the automatic
reduction of the water rate, in case the temperature is above
the operating limit.
This device is very useful during starts-up, weekend pauses,
and after a long period of inactivity.
When the water temperature of the hydronic circuit is very
high, possible blocks for overcharging are avoided, as well as
the consequent interventions of specialized personnel for the
assisted start-up.
