Water Cooled
Brine Screw Chillers
SINGLE STAGE DESIGN using ultra
efficient compact screw technology (CST) guarantees
unmatched performance and reliability over long
period of time, whilst achieving suction super
heat temperatures of as low as minus 55 degree
Celsius. These Brine chillers are compact in design
and are vibration free with sound levels lower
than 80 db.
EXCLUSIVELY DEVELOPED SCREW COMPRESSOR
WITH IN-BUILT MOTOR for low temperature
applications. These compressors have a long life
bearing structure and a patented motor cooling
design. These compressors are maintenance free
and require no oil seal change that is so prevalent
in compressors based on open screw technology.
HIGH EFFICIENCY 3 STAGE EXTERNAL OIL
SEPRATOR with coalescing filter elements.
These oils are separators constructed according
to current ASME codes, and furnished with access
manway, sight glasses for oil level inspection,
electrical heating element, dual relief valves,
and oil drain valves.
SHELL & TUBE EVAPORATOR
is built with copper tubes of 19 SWG that enables
them to withstand hard water. The copper tubes
contain Flamingo patented star turbulator inserts
that provide turbulence to the refrigerant traveling
inside the copper tubes. As a result of this turbulence
these Shell & Tube evaporators are extremely
efficient. The shell is manufactured from high-grade
steel. The evaporator is designed as per ASME
Section VIII Div.1.
SHELL & TUBE CONDENSER
built for equatorial conditions with condensing
temperatures of 45 degree Celsius considered as
the basis of design. Efficient condensing of the
refrigerant results in power savings and lower
maintenance costs due to lesser workload on the
compressor motor, rotor and bearings. The condenser
shell is manufactured from high-grade steel. The
finned copper tubes are of 16 SWG and are sized
for optimum refrigerant and water velocities.
The condensers are fitted with a safety relief
and purge valve. The condenser is designed as
per ASME Section VIII Div.1.
ECONOMIZER is provided as standard
in all Flamingo CST Brine chillers. The economizer/sub-cooler
enhances the overall capacity of the Brine chillers
by 10%, and reduces the power consumption, thereby
increasing the overall Coefficient of Performance
(COP) of CST Series Brine chillers compared to
chillers without economizer.
AIR COOLED TYPE OIL COOLER
is provided as a standard feature of the Brine
chillers to keep the oils temperature of the compressor
within safe limits.
LIQUID INJECTION is a standard
feature in Brine Chillers and is used to cool
the compressor motor winding. As soon as the discharge
temperature exceeds the normal range, an electric
solenoid coil injects liquid refrigerant to keep
the winding temperature within limits. This feature
enhances the overall life of the compressor.
ELECTRONIC EXPANSION VALVE
(Standard in models CST A & CWCR-09 to CST
A & CWCR-25) allows for precise control of
refrigerant flow through the evaporator. The expansion
valve is very sensitive to load variations and
adjusts the flow of refrigerant with short response
times to increase overall system efficiency.
CONTROL PANEL with IP-65 protection
is provided as standard part of the Brine Chillers
equipment. All control and electrical cables are
provided with thermally printed ferrule clearly
indicating connection terminals. The control panels
are powder coated and mounted within the Brine
chillers framework. In case of Magnum controller,
the microprocessor section and electrical section
are housed in separate sections of the control
panel. For ease of installation and servicing,
all control and electrical wires are mounted on
cable trays running through the length of the
Brine chillers on either side and is a standard
part of the Brine chillers equipment
ADVANCED MAGNUM STEP-LESS CAPACITY CONTROLER
(Standard in models CST A & CWCR-09 to CST
A & CWCR-25) makes Flamingo CST Brine chillers
highly efficient in part load conditions (25%~100%).
Besides the Magnum controller allows direct communication
through RS-485 to MODBUS and can be easily integrated
to BMS systems (Building Management Systems).

MAGNA AUTOMATIC STEPPED CAPACITY CONTROLER
(Standard in Models CST A & CWCR-01
to A & CWCR-08) is a basic PLC controller
specifically developed in-house for use in Flamingo
family Brine chillers. The controller allows numerous
set point ranges that can be pre configured to
particular set of values that may be considered
within the safe operating range. In case of any
breach in any of the set point value the controller
trips the Brine chillers and informs the user
about the particular malfunction on the LCD display.
Besides, the controller automatically adjusts
the capacity in a stepped format making them ideal
variable load industrial applications.
OPTIONAL REMOTE MONITORING
guarantees trouble free operation along with the
added advantage of leaving maintenance issues
to the experts themselves. Our control centre
would be routinely receiving real time information
from the microprocessor regarding the Brine chillers
health and this information will be used to perform
preventive maintenance, if required. The magnum
controller provides PC connectivity and remote
monitoring with or without BMS through dedicated
telephone phone line and optional gateway and
modem. This option is only valid in CST Brine
chillers range with Magnum
controller
OPTIONAL VFD combines the reliability
of a screw compressor with the energy savings
of a variable frequency drive (VFD). This simple,
reliable combination achieves ultra-high efficiency
levels while lowering the cost of ownership. The
Schneider ATV range of VFD’s are perfectly
adapted to the Flamingo CST family Brine chillers.
