Venture Engineering Introduces the New Trend of Air Cooled Chillers

GAMI GCU R-134a Chillers are the latest series of chillers meeting superior specifications which are mandatory for our region to withstand harsh climatic conditions. This range of air cooled screw chiller is available from 55 TR to 425 TR with 60 Hz power supply and is suitable for high ambient operation up to 52 C. These chillers are equipped with high-efficiency semi-hermetic screw compressors which offer excellent part load performance due to electronic expansion valve and condenser pressure control and long lasting robust operation. Each of these chillers will have two independent refrigerant circuits in order to offer redundancy during scheduled maintenance. The cooler offered in this chiller is direct expansion (DX) type with shell and tube evaporator configuration which is convenient for site personnel to perform cleaning procedures. The structure of the chiller incorporates minimal vibration and a low noise design. One of the key advantages is that the chiller has a compact and modular design and utilizes a small footprint for installation at site. Adding to the convenience of our customers, this chiller will be shipped in two sections for safe and easy lifting. COMPRESSORS GAMI GCU R-134a series Chiller uses COMER brand Semi-hermetic screw compressors with the latest and advanced 5:6 ratio patented screw rotor profile, which makes it highly efficient & best reliable in all operating conditions. These compressors are designed specifically for modern refrigerants, having the following characteristics: Long-life bearings. Double-walled rotor housing. Precise capacity control through injection & by passing of oil with pressure differential. Continuous (Steeples) capacity control system and automatic start unloading as standard. Refrigerant compression is achieved through the below processes and thus giving higher part load efficiencies. Suction & Sealing Compression Discharge.
COMPRESSORS The compressors can be loaded depending upon the requirement through a microprocessor which precisely modulates itself accordingly. All compressors are provided with motor winding temperature protection, discharge temperature protection, phase reversal protection, phase failure protection and oil level protection. Screw compressors in GAMI GCU R-134a Series provide virtually maintenance-free operation as there are fewer moving parts. Long file special bearings facilitate longer run periods of compressor without any need for maintenance. EVAPORATORS GAMI GCU R-134a series Chiller uses direct expansion shell & tube compact type evaporators. The tube bundle, directly welded to the shell, is not removable, the straight tube configuration allows anyway to clean easily the inner tubes. The standard construction of the shell & tube evaporators consists of the following materials: Cast ductile iron or carbon steel for headers, Carbon steel for tube-sheets, shell, refrigerant and water connections, Copper for exchanger tubes, Plastic material or carbon steel for baffles, Asbestos free and O-Ring gaskets Alloys steel bolts and nuts maximum working pressure of 16 bar (at Shell side) & 23 bar (at Tubes side) to ensure the reliability of its operation to withstand the requirements. The evaporator shell will be provided with factory fitted thermal insulation. Evaporator will have one water inlet & outlet connection suitable for Victaulic couplings. Evaporators are available both with CE and ASME certification as per requirement. Evaporators are insulated & have a fouling factor of m 2 K/W moreover, they are tested.
