AirCooled Cooled Process Screw Chillers

SINGLE CIRCUIT DESIGN Flamingo Kuhler family air -cooled process screw chillers are available in cooling capacity up to 80 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 can be added depending upon the nature of industrial application.

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.

SHELL & TUBE EVAPORATOR is built with copper tubes of 19 SWG that enables themto 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.

ULTRA EFFICIENT AIR COOLED CONDENSER built for equatorial conditions with condensing temperatures of 60 degree Celsius considered as the basis of design. Efficient condensing of the refrigerant results in power savings and lower maintenance costs. The fins are CNC manufactured in special grade aluminum of 0.15 mm thickness that are mechanically expanded around internally grooved 0.5 mm thick copper tube, in a staggered sine wave pattern

OPTIONAL HYFROPHOBIC COATED FINS results in five times better corrosion resistance than uncoated fins.

AXIAL FANS of 5-lobe, bird-wing design of Wolter (Germany) are a standard feature of Flamingo Kuhler Air Cooled Screw Chillers.Using Magnum controller the number of fans switching ON can be automaticaly controlled depending upon the compressor discharge pressure. This feature results in substantial power saving during night shifts when the ambient temperatures are particularly low.

ECONOMIZER FOR HIGHER EFFICIENCY is provided as standard in all Kuhler air cooled Chillers. The economizer/sub-cooler enhances the overall capacity of the chiller by 10%, and reduces the power consumption, thereby increasing the overall Coefficient of Performance(COP)Kuhler Series air-cooled chiller compared to chillers without economizer.

ENVIORNMENT FRIENDLY R-134A reduces discharge pressure by over 40% resulting in extremely efficient condensation thereby increasing the COP compared to R-22 (Freon) or R-407C refrigerant designs. Lowered discharge pressure also means lesser load on the refrigerant piping and hence employs longer life and lower maintenance costs.

AIR COOLED TYPE OIL COOLER is provided as a standard feature to keep the oil temperatures of the compressor within safe limits.

LIQUID INJECTION is a standard feature 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 life of the compressor.

ELECTRONIC EXPANSION VALVE (Standard in Models above Kuhler AACR 08) 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 Kuhler family range with Magnum controller.

HIGH COP/EER as a result of using R-134a refrigerant and highly efficient air-cooled condenser.

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 above Kuhler AACR 08) makes Flamingo Kuhler 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).

STANDARD MAGNA AUTOMATIC STEPPED CAPACITY CONTROLER (Standard in Models Kuhler AACR 01 to AACR 07) is a basic PLC controller specifically developed in-house for use in Flamingo range of 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 for variable load process 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 Kuhler 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 Kuhler family of chillers with Magnum controller.
