OMEGA REV
SPECIFICATIONSWater-condensed liquid chiller for interior applications featur-ing semi-hermetic screw compressors, a shell-and-tube con-denser and a dry-expansion shell-and-tube evaporator.
Refrigerant R134a
STRUCTUREConsisting of hot dip galvanised steel sections and painted with polyester powder coating (RAL 9005).
The electrical control panel consists of a hot dip galvanised steel box, painted with polyester powder coating (RAL 7035).
COMPRESSORSSemi-hermetic screw compressors with continuous capacity reduction of output power by 25 up to 100%, which allows the energy efficiency of the unit to be maximized in all opera-ting conditions.
The capacity reduction of the entire unit is always continuous, from the minimum capacity reduction step, based on the num-ber of compressors, up to 100%.
Lubrication of the compressors is ensured by the pressure dif-ference between delivery and suction.
All the compressors are fitted with check valve on delivery side, metal mesh filter on suction side and electronic protection with temperature sensors directly inserted in the windings and on the delivery pipe.
The machine is started and switched off with a forced 25% capacity reduction of each compressor and starting is of the “star-delta” type.
All the compressors are standardly supplied with a crankcase heater and a delivery valve. They are installed on anti-vibration mounts in order to reduce vibration transfer to the structure.
SOURCE-SIDE HEAT EXCHANGERFlooded type, shell-and-tube condenser featuring water flow on the tube side and refrigerant flow on the shell side. Steel shell and shell-and-tube made of copper tubing
The heads can be removed for tube inspection and cleaning.
Victaulic type couplings on the water side (complete with nipple for connection)
USER-SIDE HEAT EXCHANGERThe exchanger is a dry-expansion shell-and-tube exchanger. It is sized to maximize the efficiency of the unit, by keeping the overall dimensions and the refrigerant charge down to a minimum.
The exchanger consists of a steel shell insulated with a shell made of closed-cell foam material, while the tube bundle is made with copper tubes.
The heads can be removed for tube inspection and cleaning. Victaulic type couplings on the water side (complete with nipple for connection)
On the hydraulic connections of the heat exchanger, there are also pipe taps for the differential pressure switch, and wells for the temperature probes.
REFRIGERANT CIRCUITEach refrigerant circuit of the unit comprises:
• a delivery valve for each compressor;
• a shut-off valve in the liquid line;
• charging valves;
• a liquid sight glass;
• a replaceable solid cartridge dehydrator filter;
• an electronic expansion valve;
• pressure transducers for reading the high and low pressure values and relevant evaporating and condensing tempera-tures;
• a high pressure switch;
• a safety valve.
The pipes of the refrigerant circuit and the heat exchanger on the user side are insulated with extruded closed-cell expanded elastomer.
Compared to the mechanical expansion valve, the electronic expansion valve allows machine stability to be reached more quickly and better superheating control to maximize the use of the evaporator in all load conditions. This also acts as shut-off valve on the liquid line, as it closes during compressor stops, so preventing dangerous refrigerant migration.
ELECTRICAL CONTROL PANELThe electrical control panel consists of a galvanized and pain-ted sheet-iron box with forced ventilation and IP21 protection rating. The electrical control panel of the basic unit comprises:
• a main disconnect switch;
• fuses to protect the compressors and the auxiliary circuits;
• compressor contactors;
• a phase monitor;
• potential-free general alarm contacts;
• single potential free operating contacts;
• a microprocessor control with display accessible from the outside;
• a capacitive backup battery for electronic expansion valve.
All the electrical cables inside the panel are numbered and the terminal board dedicated to the customer's connections is coloured blue so that it can be quickly identified in the panel.
All models must be powered with 400V/3~/50Hz.
CONTROLThe microprocessor control allows the following functions:
• water temperature regulation, with outgoing water control;
• freeze protection;
• compressor timings;
• automatic rotation of compressor starting sequence;
• display of alarms;
• management of capacity reduction of the compressors during starting, switching off and load tracking;

OMEGA REV
• management of capacity reduction of the compressors in the event of operation outside the limits;
• recording of the log of the main variables;
• recording of the alarm log;
• sliding defrost management;
• RS485 serial port with Modbus protocol;
• Ethernet serial port with Modbus protocol and integrated WEB server;
• digital input for remote ON/OFF;
• digital input for Summer/Winter mode selection (only in HPW versions);
• digital input for selection of double set point.
The control has a graphic display that allows the following information to be displayed:
• water input and output temperature;
• set temperature and differential set points;
• description of alarms;
• hours of operation on the hour meter and number of start-ups of the unit and compressors;
• high and low pressure values, and relevant condensing and evaporating temperatures;
• superheating at compressor suction.
For further details on available functions and on displayed information, you can refer to the specific documentation of the control.
By default, the serial connections present as standard are ena-bled only for reading from BMS. Enabling of writing from BMS is to be requested when ordering.
CONTROLS AND SAFETY DEVICESAll the units are fitted with the following control and safety components:
• double high pressure switch with manual reset for each compressor;
• high pressure safety device with automatic reset and limited interventions managed by the control via specific pressure transducer;
• low pressure safety device with automatic reset and limited interventions managed by the control via specific pressure transducer;
• high pressure safety valve;
• operation probe at the outlet of the user-side heat exchan-ger that also acts as antifreeze probe;
• thermal overload protection for compressors;
• water differential pressure switch installed at the factory.
TESTINGAll the units are factory-tested and supplied complete with oil and refrigerant.
VERSIONSOther different versions are available to complete the OMEGA REV base line.
HE: high efficiency unitThe HE version unit uses oversized heat exchangers in order to increase the ratio between the exchange surfaces and the compressor capacity. This allows all models to achieve Euro-vent Class A for EER and consequently also high ESEER values.
OH: non-reversible heat pumpThis non-reversible heat pump is ideal for all applications in which the user does not need to produce cold water.
HPW: reversible heat pump on water sideThis water-side reversible heat pump is ideal for applications in which it is possible to switch from the user to the source circuit and vice versa. To make this option possible, the fitter must simply make provision for a system of valves in order to implement switching from one circuit to the other.
When the switching from one season to the other is imple-mented via remote or BMS signal, the unit can control motor-driven reversing valves (not supplied) so as to make this opera-tion fully automatic.
LC: condenserless unitIn this version the unit does not fit the water-fed heat exchan-ger on the source side as it can be connected to a remote condenser.
The unit is supplied as follows:
• with solenoid valves on the liquid line;
• with weld-on refrigerant connections closed with copper plugs;
• without the refrigerant load, and loaded with nitrogen.
/HWT: unit for production of high temperature waterUnits with /HWT option use compressors with oversize electric motor for production of water at high temperature. This op-tion is available for OH and HPW units or for cold only units with /DC option.
/LN: low noise unitIn this version the unit features a soundproof casing on the compressor, which consists of an outer rigid hood that is made with galvanised metal sheet and painted (RAL 7035), and whose interior is lined with a noise-absorbing matting and high noise impedance material in between.
/SLN: super low noise unitIn this version the unit comprises:
• a soundproof casing on the compressor, which consists of an outer rigid hood that is made with galvanised metal sheet and painted (RAL 7035), and whose interior is lined with a noise-absorbing matting and high noise impedance material in between;
soundproofing of the delivery and suction piping of the com-pressor by means of noise-absorbing insulating material and high noise impedance material.

OPTIONS/DC: unit with recovery condenserIn addition to the set-up of a chiller only unit, /DC units com-prise:
• a recovery condenser for recovering 100% of the condensa-tion heat on each refrigerant circuit;
• a temperature probe at the inlet of each recovery exchan-ger;
• potential free contact in the electrical control panel for ac-tivation of recovery.
When required by the system, through the closing of a con-tact, the control automatically manages activation of recovery. Recovery management is carried out through a control on the temperature of the return water. The control also automatical-ly manages safety deactivation of recovery, if the condensing pressure becomes too high, and switches to using the source-side heat exchanger.
/DS: unit with desuperheaterIn addition to the chiller only version, /DS units feature (for each refrigerant circuit) an exchanger for the recovery of heat that forms during superheating, placed in series with the source-side exchanger.
/HWT: unit for high temperatures of produced waterUnits with /HWT option use compressors with oversize electric motor for production of water at high temperature. This op-tion is available for /OH and /HPW units or for cold only units with /DC option.

REFRIGERANT CIRCUIT ACCESSORIES
SCR 0-10V signal for remote condensation control
This accessory requires provision of an analog input for a 0-10V circuit in the terminal board in order to check condensation using a modulating component, such as a valve or an inverter.
MAFR Pressure gauges
The operating pressures of each circuit of the unit can be displayed on the control by accessing the relevant screens. Also, the machine can be fitted with pressure gauges (two for each circuit) installed in a clearly visible position. These allow reading in real time of the working pressures of the refrigerant gas on the low pressure side and on the high pressure side of each refrigerant circuit.
RIC Liquid receivers The adoption of this accessory always guarantees correct feeding of the expansion valve even when the unit is subjected to wide external air temperature ranges. This accessory is standard on LC/DC units.
RUBA Compressor suction valves The valves situated on the suction side of the compressors allow the compressor to be isolated from the rest of the refrigerant circuit, so making the maintenance operations quicker and less invasive.
DVS Double safety valveWith this accessory, instead of each individual safety valve per circuit, there is a "candelabrum" with two safety valves and a diverter valve for choosing the valve in operation. This allows the safety valves to be replaced without having to drain the machine and without having to stop it.
VS Liquid line solenoid valveThis accessory prevents refrigerant migration that could damage the compressor on starting.
Standard on HP units.
BK Brine KitApplication of this accessory is compulsory if the unit has to produce water with temperature lower than +3°C (if the unit is provided with double set point or variable set point, the lower set point is considered). The ac-cessory consists of adopting an increased insulation and a suitable sizing and calibration of some components.

LIID Limitation of the current absorbed by digital input
When this accessory is requested, a digital input is prepared in the terminal board to activate the forced capacity reduction of the unit to a set fixed level. This accessory is useful when there is a need to necessarily limit the power absorbed by the unit as regards particular conditions.
LIRAAbsorbed current limita-tion with measurement of absorption
For the unit equipped with this accessory, it is possible to set, directly in the control, a maximum current that can be absorbed by the machine. The control instantly checks the absorptions, through an amperometric trans-former, and, in case of need, applies a dynamic forced capacity reduction able to always keep the absorbed current below the set threshold.
RIF Power factor correction to cosφ ≥ 0.9
With this accessory, an electrical control panel, containing power factor correction condensers to bring the cosφ of the unit to being greater than 0.9, is supplied with the unit. The condensers should be connected (by the customer) to the electrical control panel of the unit in the specially prepared terminal board.
Besides reducing the absorbed reactive power, the use of this accessory also allows the maximum absorbed current to be lowered.
SETD Double set point from digital input
For units fitted with this accessory, it is possible to preset two different operating set points and manage the change from one to the other through a digital signal. The set point temperatures must be specified when ordering.
SETVVariable set point with remote signal (0-1V, 0-10V, 4-20mA)
For units fitted with this accessory, the set point can be varied continuously between two preset values, a maximum and a minimum, depending on an external signal that can be of the 0-1V, 0-10V or 4-20mA type.
CSPSet point compensation depending on external air temperature
For units fitted with this accessory, the set point of the unit is set so that it can vary between two values, a maxi-mum and a minimum, depending on the external air temperature. The compensation ramp and the maximum and minimum values of the set point can be changed by the user.
Unless otherwise specified in the order, the control will be set to implement a negative compensation logic according to the temperatures shown in the following diagrams:

Remote-controlled user terminal
This accessory allows the terminal normally situated on the machine to be replicated on a support situated at a distance. It is particularly suitable when the unit is placed in an area that is not easily accessible.
The accessory is supplied with the unit and is to be installed by the customer at a maximum distance of 120m from the unit.
DAM Double power supply with manual switching
A manual switch to which to connect two separate power supply lines (for example, one from the mains power line and one from the uninterruptible power supply unit) is installed in the electrical control panel of the unit. The switching from one line to another is manual and compulsorily requires passing through the OFF position.
DAA Double power supply with automatic switching
A motor-driven automatic switch to which to connect two separate power supply lines (for example, one from the mains power line and one from the uninterruptible power supply unit) is installed in the electrical control panel of the unit. The switching from one line to another is automatic and compulsorily requires passing through the OFF position.
RMMT Maximum and minimum voltage relay
This accessory constantly monitors the voltage value and the unit's power supply phase sequence. If the supply voltage does not fall within the set parameters or there is a phase reversal, an alarm is generated that stops the machine to prevent damage to its main parts
IA Automatic circuit breakersWith this accessory, automatic circuit breakers are installed instead of fuses for the protection of auxiliary loads. Also, the same accessory uses automatic circuit breakers with adjustable thermal overload protection to protect the compressors.
Relay for management of 1 external pump
This accessory can be requested for units without pumps and allows a pump outside the machine to be con-trolled.
Relay for management of 2 external pumps
This accessory can be requested for units without pumps and allows two pumps outside the machine to be controlled with a running/stand-by logic by implementing a rotation on the hours of operation.

GABB Packaging in wooden crate The unit is enclosed in a treated and ISPM 15 marked wooden crate. This accessory is strongly advised for shipping by container.
FLUSFlow switch (instead of the water differential pressure switch)
As an alternative to the differential pressure switch (standard flow sensor), it is possible to request the pad-dle flow switch as accessory. This detects when there is no water flow to the user-side exchanger and sends a signal to the control of the unit that will stop the compressors to prevent damage to the exchangers. The flow switch is supplied with the unit (installation by the customer) and replaces the water differential pressure switch (standard).
FW Water filter
To protect the elements of the hydraulic circuit (in particular, the exchangers), there are Y filters that can stop and settle the particles that are normally present in the water flow and would otherwise settle in the more delicate parts of the hydraulic circuit and damage its heat exchange capacity. Installation of the water filter is mandatory even when it is not supplied as an accessory. Accessory supplied with the unit.

Values applying at the following conditions: temperature of input/output water to/from source side 30/35°C; temperature of input/output water to/from user side 12/7°C. Lw: sound power value based on measurements made in accordance with ISO 3744 and the Eurovent certification programme. This certification refers specifically to the sound power level in dB(A). This is therefore the only acoustic reading to be considered binding.Lp: mean sound pressure level, measured at 1 metre from the unit, in free field on a reflecting surface. Non binding value obtained from the sound power level
