Voltas Electro-mechanical and Refrigeration Business Group, an 150:9001 company is the pioneer and leader in the field of electro-mechanical and refrigeration. Because of its commitment to provide customers with the latest green technology and ‘best value for money Voltas has introduced a new series of energy-efficient Chillers, using the environment friendly refrigerant R-134a. The chillers have become an ideal choice for  Green Building Projects  and other air-conditioning applications. Available in a wide range of capacities, each unit is tested in a state-of-the-art facility, matching international standards, prior to their delivery – thus ensuring reliability and optimum performance. WIDEST RANGE ECBC Series – 100 TR to 380 TR Green Series 90 TR to 360 TR (For models of higher & lower capacities than those mentioned here, please contact nearest Voltas sales office.) EIGHT POWERFUL FEATURES: Exceptional Energy Efficiency by Design • Basic equipments are designed to operate compressors on a comparatively better suction pressure and an optimum discharge pressure, to maximize efficiency benefit. • Compressor with step-less capacity control mechanism, operates in response to the chilled water outlet temperature, and precisely matches the part-load requirements without hunting. • Electronic expansion with controller and sensors, respond quickly to the variable operating conditions and enhances efficiency. • Fan cycling programmed on discharge pressure, saves the energy consumption during low ambient temperature, or at partial load operation. • Compressor staging has been programmed to save energy, by running adequate numbers of compressors at maximum efficiencies, even at different loads. • Economize, greatly improves efficiency of the unit and full-load cooling capacity. Additional sub cooling is created by expanding small part of liquid refrigerant from condenser, to sub cool remaining part of total refrigerant, in a compact plate-type heat >, exchanger (PHE). The Economizer’s working process is depicted in the diagram. Screw compressor is provided with an additional suction port called ECO port, which makes it possible to suck the refrigerant vapour from PHE, to accomplish economizer heat transfer. Screw Compressor Means Efficiency and Reliability Screw Compressors are sourced from industry’s best manufacturers, and are tested in accordance with ARI Eurovent standards. The Compressors are known for efficiency, ruggedness, reliability and consistent part-load operations.

Voltas is the pioneer and a leading provider of integrated end-to-end solutions in the field of electromagnetically and refrigeration. We are committed to  provide customers with technology that suits their needs and have introduced a wide variety of air-cooled and water-cooled scroll chillers with R 22 and R 407 C refrigerant options. With ISO 9001 standard certified factories, Voltas possesses total capability in the manufacture of scroll chillers.These chillers are available in a wide range of capacities from 13 TR to 100 TR.They are easy to install and commission and can handle varying cooling requirements, aided by multiple compressor configurations. Voltas scroll chillers have become an ideal choice for various air conditioning applications including, office spaces, banks, hotels, hospitals, shopping malls, multiplexes, commercial req uirements. FEATURES • Scroll Compressor with R 22 & R 407 C Refrigerant Options • Energy Efficiency • Modular Design • Application Flexibility • Low Noise & compact • Easy-to-use Microprocessor Panel & Controls POWERFUL FEATURES: Voltas chillers are available in a wide range of models, with R 407C & R 22 refrigerants.

Higher energy efficiency — Tandem compressor models Scroll chillers from 52 TR to 100 TR use compressors operating in tandem. This improves the operating efficiency during part load periods, since the entire condenser area is utilized for the heat rejection even though only one compressor may be in operation. Capacity Modulation Multiple compressors are used in most of the models, with independent refrigerant circuits. The microprocessor controller ensures that only the required number of compressors operate during part load conditions, there by saving power. Operating Reliability The compressor is a no contact scroll design with the motor cooled by the suction gas. Higher capacity scroll chillers use tandem compressors with suction gas distribution restrictor which allows balanced operation of compressor.The chillers are charged & tested in the factory prior to despatch , enhancing operating reliability. Quiet Operations The chillers use ultra quiet, high efficiency scroll compressors.The condenser fans are designed for low noise levels. Easy to install The chillers are pre-wired, fully charged and run tested at the factory, saving installation and start up time. Voltas Countrywide After Sales Service A nationwide service networks backs every unit. After the initial warranty period, Voltas offers annual service schemes. More than 90% of the customers have opted for these schemes. You cannot get a better insurance.
