Water Cooled
HVAC Screw Chillers
SINGLE CIRCUIT DESIGN Flamingo
Aircon family water-cooled process screw chillers
are available in cooling capacity up to 500 TR
in a single circuit design.Optional twin circuit
available on demand.
EFFICIENT TWIN ROTOR SCREW COMPRESSOR
that is semi-hermetic in construction, thereby
making it maintenance friendly. Due to geometrically
symmetrical moving parts, the compressors have
extremely low vibration and are tested in accordance
with AHRI/European Standards. These screw compressors
come with an in-built oil separation system and
an additional external oil separator.
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 conditionswith 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 AS STANDARD IN AIRCON SCREW
CHILLERS enhances the overall capacity
of the chiller by 10%, and reduces the power consumption,
thereby increasing the overall Coefficient of
Performance(COP) of the chiller when compared
to non-economized chillers of similar cooling
capacity.
ELECTRONIC EXPANSION VALVE (Standard
in Models Aircon A, B & CWCRP07-13 to A, B
& CWCRP07 26) 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 achieve power savings. This option is
only valid in Aircon range with Magnum
controller.
CONTROL PANEL with IP-65 protection
is provided as standard part of the 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 chiller framework.
In case of Magnum
controller, the microprocessor section and
electrical section are housed in seprate 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 chiller on either side and is a
standard part of the chiller equipment.
ADVANCED MAGNUM STEP-LESS CAPACITY CONTROLER
(Standard in Models Aircon A, B & CWCRP07-13
to A, B & CWCRP07 26) makes Flamingo Aircon
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). (Read More on Magnum
controller)
MAGNA AUTOMATIC STEPPED CAPACITY CONTROLER
(Standard in Models Aircon A, B & CWCRP07-01
to A, B & CWCRP07 12) is a basic PLC controller
specifically developed in-house for use in Flamingo
family chillers. The controller allows numerous
set points 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 will
trip the chiller and inform 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 comfort cooling 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 chiller 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 Aircon 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
adaptable with the Flamingo Aircon family of chillers
with Magnum
controller.
OPTIONAL HEAT PUMP increases
the versatility of the AirCon Family chillers
as it can double up as a Heat Pump just by sliding
the reversing valve direction, eliminating the
need to install boilers for central heating applications
during winter seasons.
OPTIONAL HOT WATER PORT provides
hot water for various utilities with in commercial
establishments without any increase in the chiller
power consumption. This option utilizes the waste
discharge heat from the compressor to provide
hot water at temperatures up to 60 degree Celsius
that can be used for various utilities within
a commercial building and eliminates the need
to install boilers for heating water applications.
OPTIONAL DIRECT EXPANSION design
can also be availed for direct coupling
to indvidual or multiple air handling units (AHUs).
