air cooled screw chiller

Functions and Features:

CHOICE OF SCREW COMPRESSOR of Hanbell (Taiwan), Bitzer (Germany) & J&E Hall (UK). All options are semi-hermetic in construction, thereby making it maintenance friendly. These compressors have extremely low vibration levels due to geometrically symmetrical moving parts and are tested in accordance to 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. Oil level switch, CCH heater and economiser port along with check valves at suction and discharge port are provided as standard part of the OEM supply.

HIGH COP/EER as a result efficient condensing of the refrigerant. These air cooled chiller units are designed to meet the applicable requirements of ASHRAE/ANSI 15 Safety Code.Since these condensers are generously sized, efficient condensing of the refrigerantleads to lower IKW compared with other available brands.

SHELL & TUBE EVAPORATOR is built with copper tubes of 19 SWG that enables them to withstand hard water with PH even greater than 8. The copper tubes contain Flamingo patented star turbulator inserts that provide turbulence to the refrigerant flowing through the copper tubes. As a result of this turbulence these Shell & Tube evaporators have extremely efficient heat transfer with the copper tube. The shell is manufactured from high-grade steel. The evaporator is designed as per ASME Section VIII Div.1.

WIDE RANGE AVAILABLE FOR A CHOICE OF AMBIENT TEMPERATURES from 35 deg. C to 50 deg. C. Additional features such as anti-freezing devices can be added on the air cooled screw chiller for conditions experiencing sub-zero temperatures.

ULTRA EFFICIENT CONDENSING Inner grooved copper tubes are used to offer ultra efficient cooling and this mechanism not only offers and opportunity for power saving but also help reduce maintenance costs considerably. Special grade aluminum that is of 0.15 mm thickness is used and expanded mechanically to fit a copper tube that is 0.5 mm thick, and this is in a sine wave pattern, and this is how the CNC manufactured fins are made. A feature that Flamingo MRI Chillers are known for is the Axial Fan that has 5 lobes and a bird wing design. To facilitate additional power saving, the compressor discharge pressure will automatically switch on the fans.

ECONOMIZER FOR HIGHER EFFICIENCY is provided according to the refrigerant opted and depending upon the chilled water/brine temperature range desired.Usually, economiser is provided as standard part of OEM supply in process chillers opted for evaporating temperature of 5 deg. C or lower. 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).

AVAILABLE IN A CHOICE OF REFRIGERANTS R-22 (Freon), R-407C and R-134a. Both R-407C and R-134A are environment friendly and non-ozone depleting refrigerants.

ADDITONAL AIR COOLED TYPE OIL COOLER is addeddepending upon the choice of refrigerant and the chilled water/brine temperature desired. The oil cooler helps maintain the oil temperatures flowing through the compressor within safe limits. The oil cooler fan is automatically controlled depending on the oil temperature. This feature enhances the life of the screw compressor.

LIQUID INJECTION is a standard feature and is used to keep the compressor motor winding temperature in check. 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 screw compressor.

THERMOSTATIC EXPANSION VALVE is provided as a standard part of the air cooled screw chiller equipment. Electronic expansion valve can be optionally provided.

CONTROL PANEL with IP-65 protection is provided as standard part of the air cooled chillerequipment. The control panel is rain protected keeping in mind its installation in open spaces.

MICROPROCESSOR BASED CONTROLLER is a standard part of the air cooled screw chiller equipment.  The controller allows numerous set points that can be 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 after the fed safety delay period has passed and display it on the LCD display. Besides, the controller automatically adjusts the capacity in a stepped format making them ideal for variable load applications.

Optional Features:

ELECTRONIC EXPANSION VALVE allows for precise control of refrigerant flow through the evaporator. The electronic expansion valve is very sensitive to load variations and adjusts the flow of refrigerant with short response times to achieve power savings.

ADVANCED MAGNUM STEP-LESS CAPACITY CONTROLER makes the chiller highly efficient in part load conditionsas it adjusts the capacity steplessly (25%~100%). Besides the Magnum controller allows direct communication through RS-485 to MODBUS and can be easily integrated to mostBMS systems (Building Management Systems) available in the market.

SOFT STARTER providessmooth acceleration as voltage or current is applied gradually. Besides Soft starters also stop the motor gradually as opposed to the sudden jerk experienced in DOL or Star Delta type starter panels. This additional feature enhances the compressor bearing life.

HYDROPHOBIC COATED FINS that repels condensate and improves efficiency of the air cooled condenser. The hydrophobic coating significantly reduces the friction of air over fins so they do not catch any dirt or grime and reduces corrosion.

INDIVIDUALY CUSTOMISED solutions are also available for direct expansion options.

CIRCULATION PUMP & TANK MODULE can be optionally provided along with the chiller for circulation of chilled water/brine to the process. This reduces installation time.
