FEATURES AND BENEFITS
Water cooled liquid chiller for indoor installation
GENERAL CHARACTERISTICS OF THE UNIT
The MWC unit is designed for industrial and commercial
applications where customers require reduced total cost of
ownership for new air conditioning equipment.
As main characteristics the MWC unit offers multi scroll
R410A compressors with two circuits for safety operation and
oversized heat exchangers for high full and part load energy
performances (Class B effi ciency / ESEER > 6.0).
The MWC is the solution for indoor installation. Thanks to
very compact dimensions and limited footprint MWC can be
installed easily into any technical room.
The MWC is available in 2 main versions to meet all customer
requirements and applications :
- MWC version is the water-cooled chiller. This version can
be used for air conditioning applications in association with
a separate dry-cooler or using ground water. The MWC version can also be used for heating applications. With the “hot
water set point control” option the MWC range can supply
hot water up to +50°C.
- MRC version is the split version without condenser. This
version can be used for air conditioning applications in association with a remote air-cooled condenser
COMPRESSOR
MWC is using R410A vibration-free compliant® scroll compressors
to guarantee a low operating sound level, a high durability and
reliability and no maintenance.
- Exclusive Compliant® Scroll design with both axial and radial
compliance to increase compressor operation tolerance to
liquid refrigerant, substantially improving durability and reliability.
- Motor cooled by suction gas.
- Electronic control of the compressor discharge temperature.
- Motor protection device against high temperature or over
current situations.
- Discharge non-return valve.
- Compressors assembly installed on an independent chassis
supported by anti-vibration mountings.
- Optional sound-proofed panel enclosures to reduce noise
emissions.
WATER HEAT EXCHANGER (EVAPORATOR
AND CONDENSER)
MWC is using stainless steel brazed plate heat exchangers with
true dual circuit.
REFRIGERANT CIRCUIT
MWC is using R410A refrigerant in 2 independent circuits that
allows operation at 50% of the capacity in case of issue on one
circuit.
Each circuit includes:
- A refrigerant charge reduced by 30% thanks to the use of
R410A combined with plate heat exchanger
- Suction piping with thermal insulation.
- Moisture sight glass on the MRC version
- Filter drier with removable cartridge fi lter.
- Thermostatic valve or electronic expansion valve (optional
from size 180 to 570, standard on size 650 & 720).
- Temperature sensors and pressure transducers.
- Leak-tight refrigerant circuit with brazing carried out under
nitrogen by certifi ed technicians.
- Each refrigerant circuit is pressure and leak tested with a
Hydrogen/Nitrogen mixture, and vacuumed before being
charged with refrigerant. All units are then subjected to a
complete functional and operational run test to guarantee
perfect sealing before leaving the factory.
- Evaporator protected against freezing risks thanks to an
electronic water fl ow switch
- Condenser protected against low condensing temperature
thanks to a 0-10 V output signal available from the controller
to control a condenser water inlet valve (Not from Lennox
supply).
CASING/CHASSIS
- Chassis made of galvanised steel sheet metal painted with
a RAL 7016 (grey) powdered polyester paint.
- Optional casing with removable panels made of galvanised
steel sheet metal painted with a RAL 7016 (grey) powdered
polyester paint.

FEATURES AND BENEFITS
ELECTRICAL BOX
The MWC is designed for 400V/3/50Hz supply.
- Unit electrical cabinet, components and wiring in compliance
with EN 60204-1 electrical directive.
- 400V/3/50Hz power supply (without neutral) with a single
point of power connection.
- IP24 protection class.
- Recognized brand electrical components for ease of maintenance.
- Main on/off switch mounted on the front panel.
- DC50 user interface mounted on the front panel.
- 400/24 V transformer to supply the control circuit.
- Labelled electrical wires to facilitate maintenance and diagnostic.
- Optional power and control circuit for the pumps.
CONTROL
CLIMATIC™ microprocessor based control is providing the
following functions:
- 4 scheduling time zones per day over 7 days to allow energy
consumption management according to the building use and
environmental constraints.
- PI control of the water temperature with operating time
equalisation of the compressors.
- Intelligent advanced control algorithm to protect the compressors against excessive short-cycling and to allow operation
of the unit without buffer tank in most comfort air conditioning
applications (e.g. unit with fan-coils). Refer to minimum installation water loop volume recommendations.
- Water pump control with operating time equalization and
automatic change-over in case of a pump fault (Twin pump
only).
- Master/slave or cascade control of two chillers operating
in parallel with operating time equalization and automatic
change-over in case of a unit fault.
CLIMATIC™ is pre-factory confi gured with default settings
allowing a fast commissioning on site. The DC50™ user interface
with graphical display is easy to use, intuitive. Main customer
parameters can be read or modifi ed without main power shut-off
(Entering/leaving water temperatures, alarms, water set-points,
high and low pressure readings).
The DS50™ service display (optional) is a .plug and play"
controller that allows service people to read and modify all
unit parameters (Unit settings, operating time and number of
compressor starts, low and high pressure reading, read the
history of last 32 faults...).
COMMUNICATION
The control board is equipped with a RS485 serial communication
port to allow remote management through communication
bus.
According to the wished communication protocol, our control
board can be fi tted with ModBUS®, LonWorks® or BacNET®
communication interface (options).
The main control board has free dry contacts that allow remote
control of the unit by wired cable:
- Remote on/off of the unit.
- Remote alarm reset to re-start the unit.
- Alarm or alert indications.
- Free customer contact.
With the optional extension board BE50, it is possible to get
additional customized digital or analog inputs/outputs for remote
control of the unit:
- Fault pumps (dry contact).
- Operation indication at 100% on circuit 1 or 2 (dry
contact).
- Dual water set-point management (dry contact).
- Force heating or cooling mode (24V AC input).
- Power limitation by disabling circuit 1 or 2 (24V AC input).
- Force unoccupied mode (24V AC input).
- Water set-point offset based on a 4-20mA signal.
DIRECTIVES
The unit is built to meet European norms and standards &
Eurovent certiFIcation performance standards.

HYDRAULIC DATA
MINIMUM WATER CONTENT OF AN INSTALLATION
Thanks to multi step capacity control and smart anti-short compressor cycling, MWC™ can work with minimum water loop volume
as defi ned here below. This can eliminate the need for a buffer tank in most of air-conditioning applications (e.g. MWC™ application
with fan-coil units). :
Vmini = 86 x Q / (Nstages x Dt)

Where :
NstageNumber of control steps available in the unit

Important note: In case MWC™ is used in air-conditioning applications with a short water system (e.g. MWC™ application with air
handling units) or in case MWC™ is used for industrial process cooling, it is mandatory to use a buffer tank.

Note : The volume of the condenser water loop has no impact on the chiller operation. In heat pump operation (with hot water set point control option)
the minimum volume of the condenser water loop must be calculated based on the heating capacity using the same formula.
