Mechanical accessories
GM (M)
Pressure gauge unit. Consisting of 4 pressure gauges that display the pressure of the refrigerant fluid on the intake and
delivery of the compressors of both circuits..
GP (M)
Protective grilles. Consisting of metal grilles that protect the coils with extended surfaces.
AVM (F)
Spring vibration dampers. Consisting of 4 spring vibration dampers to install under the unit. They reduce the mechani-
cal vibrations generated by the compressor and fans during their normal operation, and that are then transmitted to the bearing
surface of the machine. The insulation degree provided by the vibration dampers is about 90%.
SAA (M) Water storage tank.
Made of adequately thick painted sheet metal, this reduces the number of compressor start-ups
and fluctuations in the temperature of the water conveyed to the users. It is insulated with thermal barrier material to prevent the
formation of condensation and heat exchanges towards the outside. The accessory is inclusive of water safety valve, air vent,
water drain and antifreeze heater connection. In conjunction with the Pumping Module accessory, it can be supplied in 3 different
configurations: Storage on the Delivery, Storage on the Return, Storage pre-engineered for the Primary and Secondary circuit.
Pumping module with 1 o 2 Pumps (The second pump, installed in parallel to the first, allows to have one workable
pump to use if the first doesn't work)
.
:
Besides the pumps, this accessory is equipped with all the hydraulic components (water
filter, expansion tank, on-off valves, water pressure gauge) required for complete installation and easy maintenance.
Different water accumulation tank configurations are therefore available in combination with the pumping module accessory:
MP-AM : Storage on the water supply plant Delivery(1):
The pump draws water from the supply plant, sends it to the plate
type heat exchanger and then to the inertial storage tank. In this configuration, when the pump operates in its nominal condi-
tions, it is able to supply the circulating water with a residual head of about
140 to 220 kPa
in the Cooling mode (from 13 to 20
m.w.c.) and
from 80 to 150 kPa
in the Heating mode (from 14 to 22 m.w.c).
MP-AR: Storage on the water supply plant Return(1):
The pump draws water from the inertial storage tank, sends it to the plate
type heat exchanger and then to the system. In this configuration, when the pump operates in its nominal conditions, it is able to
supply the circulating water with a residual head of about
140 to 220 kPa
in the Cooling mode (from 13 to 20 m.w.c.) and
from
80 to 150 kPa
in the Heating mode (from 8 to 22 m.w.c).
MP - PS: Storage pre-engineered for the primary and secondary circuit.
The pump s sole task is to allow water to circulate
around the primary circuit: this circuit includes the storage tank and plate type heat exchanger (chiller s water circuit). Assembly
of the pumping section for the secondary circuit is at the installer s charge and includes the storage tank (with pre-engineered
wet connections) and the system to be supplied.
KT - Pipe kit
, consists of two steel pipes insulated with heat barrier material. If the Pumping Module accessory is not installed,
the pipe kit is obligatory to be taken.
