The technical specifications of the main components forming the units are:

1. Fans. These are the helical type with scythe-shaped vanes to increase efficiency

and reduce the sound emissions. They are complete with protective grilles for accident
prevention purposes (1B).

2. Compressors these are the ROTARY type (for mod. 16-19-24) and the SCROLL

type for mod. 30-38-42-50), with orbiting coil equipped with built-in thermal protection
and oil heater (only for IP units). .

3. Bearing structure made of galvanized sheet metal panels coated with polyuretha-

ne powder paint to ensure good protection against adverse weather conditions.

4. Plate-type evaporator made of braze-welded stainless steel (AISI 316). It is instal-

led within a shell of thermal barrier insulating material to prevent the formation of con­densation and heat exchanges towards the outside. Standard supply also includes an
antifreeze heating element and a differential pressure switch on the water supply cir­cuit to avoid the risk of freezing if the water flow is shut off for some reason.

5. Condensing/evaporating bank, the aluminium finned pack type with shaped profi-

le to increase the heat exchange coefficient and with copper pipes arranged in stagge­red rows, together with a subcooling circuit.

Hydraulic and chilling circuit components (Fig.2):

1. One-way valves (only IP units), make the

refrigerant obligatorily pass through the appro­priate heat exchangers, depending on the
operating cycle.

2. Low pressure switch, with fixed setting. It is

installed on the suction pipe and blocks the
compressor if the operating pressures drop
below the tolerated values. It automatically
resets as the pressure increases. If it activates
frequently, the unit will block and can only be
restarted by resetting via the user interface
terminal.

3. High pressure switch, with fixed setting. It is

installed on the delivery pipe and blocks the
compressor if the operating pressures exceed
the tolerated values. If it activates, the unit will
block and can only be restarted by resetting
via the user interface terminal.

4. Thermostatic valve, of the type with external

equalizer.
Used as both a heat pump and chiller, it’s task
is to supply the evaporator correctly, keeping
the selected degree of superheat at a steady
level.

5. Dehydrator filter of the mechanical type. Retains impurities and traces of moisture in the circuit.

6. Differential water pressure switch. This is standard supply and is installed on the connections between the exchanger’s

water inlet and outlet. If it activates frequently, the unit will block and can only be restarted by resetting via the user interface
terminal.

7. 4-way cycle reversing valve (IP units only). Reverses the direction in which the refrigerant flows when the summer/winter

operating modes change.

8. Fluid receiver (IP units only). This is a plenum tank that accounts for the refrigerant charge variations required by the machi-

ne as the summer/winter operating modes change.

ACCESSORIES AND OPTIONAL EQUIPMENT

Mechanical Accessories

Pumping and Storage module

The purpose of the storage and pumping module is to lower the number of compressor surges, increasing the amount of water
in the system and, thus, its thermal inertia. It can be coupled to the side of the chiller and has the same depth and height dimen­sions. Available in the Standard versions for all models and in the High Head version for models 16-19-24-30. In nominal ope­rating conditions in the cooling mode, the Standard Version is able to provide the circulating water with 40 to 102 kPa residual
head, while the High Head Version has 123 to 142 kPa residual head.

With reference to the figure alongside and depending on the model, the Storage and

Pumping Module is equipped with:

1A. Multiple stage pump. With a high head, able to suit the majority of installation requi-

rements. All pump components that come into contact with the pumped fluid are made
of stainless steel.

1B. Circulation pump. Three-speed circulation pump that provides the chiller with the

right water flow rate. The 3rd speed is set during the production phase: it is inadvisa­ble to modify this speed as the operation of the Module would be impaired.

2A. Pump suction sleeve (1” GAS female) used for returning from the system.
2B. Returning stub pipe from the system (1” GAS male) used for returning from the

system.

3. Pressure gauge. Indicates the pressure level in the storage tank (only for mod. 30-

33 in the High head version and mod. 50 in the Standard version).

4. Delivery stub pipe of the system (1” GAS male).

5. Safety valve. With fixed setting. Activates when the pressure in the tank exceeds the

preset values.

6. Drain cock. Drains the water from the storage module to prevent it from freezing during

winter periods, if not used for hot water storage.

7. Electric antifreeze heating element connection (Accessory). Allows the storage

tank’s electric antifreeze heating element to be installed.

8. Storage tank.Reduces the number of compressor start-ups and fluctuations in the

temperature of the water conveyed to the users. It is insulated with polyurethane foam
to prevent the formation of condensation and heat exchanges towards the outside.

9A. Automatic air venting. Vents the tank when the system is filled.
9B. Air venting. Positioned on the highest part of the module’s wet pipes, it bleeds the

air from the module itself when the system is filled.

10. Metal gauze water filter. Can be inspected. Installed on the pump/circulator intake.

Preventing machining residues (dust, swarf) in the water pipes from entering the
pump or plate-type heat exchanger.

11. Surge chamber. This is a closed, diaphragm type chamber. It absorbs the variations

in the volumes of water in the system caused by temperature variations.

12. Metal structure. Made of galvanized sheet metal panels coated with polyurethane

powder paint to ensure good protection against adverse weather conditions.

GP - Protective Grilles

The kit comprises two electrowelded, painted grilles to protect the coils with extended sur­faces.

ST - Bracketing kit for the Unit + Pumping and Storage module

The bracket kit comprises four bent sheet metal elements assembled together by self­threading screws. The distance between the holes allows the pre-fixed chiller and storage
module to be recriprocally fastened together. Equipped with 8 rubber supports that redu­ce the extent to which the units transmit vibrations to the bearing points. The brackets
have holes so that they can be fixed to the floor or to shelving. They are supplied painted
the same colour as the unit and storage module.

AVG - Rubber vibration dampers.

Kit comprising 4 cylindrical vibration dampers made of vulcanized rubber on metal washers.
They reduce the mechanical vibrations transmitted by the compressor and fan/s to the bearing
surface of the machine during normal operation. They can be used/installed under the unit (4
pcs), under the Storage Module (4 pcs) or under the Bracketing Kit (8 pcs).

KT - Flexible wet connections.

Allow the components to be quickly installed, even when the connections are slightly misa­ligned, also limiting the extent to which vibrations are transmitted from the chiller to the sto­rage tank and, consequently, to the system.

AV - Hydraulic quick couplings

Used for the wet connections between the Unit and Storage module, making the unit + module assembly as compact and small
in size as possible. The kit consists of two couplings complete with seal and two threaded stub pipes with relative groove.
NOTE: If the hydraulic quick couplings are not used, refer to the coupling measurements given in the tables.
The kit consists of two couplings complete with seal and two threaded stub pipes with relative groove.

Electrical Accessories

CR - Remote Control

This device allows all the control and monitoring functions of the control unit on the machine to be controlled up to 100 meters
away from the actual machine itself. Use a three-pole or three-wired section cable in PVC type N07-VK with a 1 mm

2

wire sec­tion for the connections. The transmission line must be routed in a dedicated duct, separate from any electric powering lines
(230/400 V).
The remote control has the following keys:

1 - MODE key : selects the operating mode
2 - ON/OFF key : turns the unit ON/OFF and resets the alarms
3 - Mode + ON/OFF keys : used to access and quit the various menu levels
4 - UP key : scrolls forwards through the menu items or increases the value of a parameter
5 - DOWN key : scrolls backwards through the menu items or decreases the value of a para-

meter

RAG: Antifreeze heater Storage Tank (accessory used in conjunction with the Storage
and Pumping Module)
Glow plug type; maintains the water in the storage tank at a temperature able to prevent ice from forming during winter stand­stills. (250W/230V-1/50Hz).

OP - Programmer Clock

This is a device (housed in a modular casing 45 mm in width) that allows the unit to be turned on and off (without needing to be
regulated) by means of the remote controlled digital on-off input on the control board of the unit. Up to 14 settings can be ente­red, divided as required throughout the 7 days of the week. The clock is connected to the machine with 4 wires of the PVC N07­VK type with a 1.5 mm2 section. Take care to route the cable since the wires are live (230V mains voltage).
