Water Cooled
HVAC Scroll Chillers
TWIN INDEPENDENT CIRCUIT DESIGN
guarantees greater reliability. In case of part
load conditions any one of the two circuits would
automatically shut down thereby lowering running
costs. In the event of breakdown in any one of
the circuits, the performance and functioning
of the other circuit is not affected. Breakdowns
can be repaired without switching off the chiller.
For capacities greater than 40 TR (140 kW) multiple
scroll compressors can be added proportionately
in series to each circuit.
EFFICIENT SCROLL COMPRESSORS
of Danfoss (Denmark) are provided as standard
in all Kuhler family scroll chillers. These compressors
come with a high efficiency in built motor and
hybrid-wrap scroll design that helps reduce energy
costs in normal operating conditions and delivers
high capacity and an optimized pressure ratio
for refrigeration applications.
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 turbulence
the Direct Expansion type Shell & Tube evaporators
are extremely efficient. The evaporator is of
twin circuit design. The evaporator shell is manufactured
from high-grade steel. The evaporator is designed
as per ASME Section VIII Div.1.
HIGH PERFORMANCE 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. 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.
HIGH COP/EER as a result efficient
condensing of refrigerant. These durable industrial
chiller units are designed to meet the applicable
requirements of ASHRAE/ANSI 15 Safety Code.
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
STANDARD MAGNA CONTROLER is
a microprocessor based PLC controller specifically
developed for use in Flamingo range of chillers.
The controller allows programming 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 alpha numeric LCD
display. If problems should arise, built-in diagnostics
allow fast, simple troubleshooting. Besides, the
controller automatically adjusts the capacity
in a stepped format making them ideal for variable
load process cooling applications.
OPTIONAL MAGNUM CONTROLLER
allows direct communication through RS-485 to
MODBUS and can be easily integrated to BMS systems
(Building Management Systems). Besides the Magnum
Controller (Read More on Magnum
controller)
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 Kuhler range
with Magnum
controller.
OPTIONAL ELECTRONIC EXPANSION VALVE
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 family range with Magnum
controller.
OPTIONAL SS PUMP (standard in
models Aircon A, B & CWCS 01 to A, B &
CWCS 03) of Grundfos (Denmark) can be optionally
provided along the chiller.
OPTIONAL SS TANK WITH AUTO TANK REFILL
(standard in models Aircon A, B & CWCS 01
to A, B & CWCS 03) of sufficient capacity
depending upon the Chiller model can be optionally
provided along with the Flamingo Aircon range
of chillers.
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).
