ing components: lined buffer tank with an antifreeze heater,
centrifugal pump, expansion vessel charged with nitrogen at
1.5 bar, relief valve set to 6 bar, water circuit pressure gauge,
air bleed valves, filling valve and drain valve. Also includes
a mesh filter for the water circuit. This filter is supplied loose
for installation at the most convenient point.
Unit without hydro kit
Includes the elements described in the previously mentioned
specifications, less the hydro kit (pack). The water circuit
includes an air bleed valve. Connections are ready for field
installation.
Unit with pump
Comprises the elements mentioned in the above specifica-
tions, including the water pump. The water circuit is equipped
with an air purging valve. Connections are ready for instal-
lation on job site.
Protecting grids
To protect the coils from possible impacts. Made of steel
rods and painted with oven baked polymerized white enamel
(RAL9002).
Accessories and options
Flow switch
For field installation. Insures sufficient water circulation when
the unit is in operation.
Anticorrosion protection of fins
Two options are available:
- Aluminium fins with Blue Fin primer.
- Copper fins.
2 ½" water filter
Stainless steel screen with 1mm. diameter perforations. Sup-
plied as a standard element on units that include the hydro
kit (pack).
Optional on units that do not include the pack.
The warrantee of the unit will not be valid if a water filter has
not been installed.
Remote control unit
Wall-mounted remote control unit with keyboard for cool/heat
and ON/OFF functions. Includes power supply, alarm and
cool/heat LEDs. Maximum cable length: 50 m.
BMS connections
By means of a serial board, the system can be connected to
a standard RS485 monitoring network.
Dual pump
This is a single body, two-motor pump. The operation of same
must be enabled and programmed from the Configuration
menu on the machine control unit. The second pump starts
when the magneto thermal protector of the first pump has
disconnected, and vice versa. This control allows rotational
operation of said pumps in accordance with operating hours
or number of starts.
Low noise level (LN) units
These include anti-noise casings mounted on the compres-
sors and sound insulation liming the panels of the compres-
sor chamber.
Antivibratory supports
Whenever necessary to reduce to a maximum vibrations and
noise caused by the unit, you can use a set of steel spring
antivibratory supports, that should be installed between the
supporting chassis of the unit and the base or floor on which
same should be set. This base should be solid and dimen-
sioned in accordance with the weight to be supported. To
fasten the supports to the base of the chassis, 12 Ma screws
are used. The antivibratory supports accessory includes 6
springs. These supports should be distributed amongst and
fastened in the drilled holes in the base , the location of which
is detailed in the General Dimensions section.
