VICTAULIC CONNECTIONS
1. Take away the supplied connection union by acting on the
connection joint Victaulic.
2. Weld the union to the installation pipe.
3. Perform the connection between the installation pipe and
the evaporator, using the joint.
Do not weld the system pipe with the Victaulic
connection joint attached.
The rubber gasket might be irreparably damaged
HYDROPACK - OPTIONAL
Self-adjustment: The modular pumping system makes it
possible to automatically reduce the water flow rate if the
temperature increases above the operating limit (excluding
hydropack with 1 pump).
The device is also very useful during start-ups, on weekends
and after a long period of inactivity.
When the temperature of water in the hydronic circuit is
especially high, this prevents undesired shutdowns due to
overload resulting in call-outs of service technicians to assist in
restarting.
Furthermore, Hydropack allows a variable water capacity flow
in the systems where this would be called for.
By equipping the refrigerating units with the Hydropack
accessory, the necessary flow capacity/head are provided in
different versions:
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 60% of the charge. This solution is
more reliable than the traditional ones with a single great
power pump.
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.
