Dalgakiran EBSV Series

Dalgakiran EBSV сhillers are water-cooled freon chillers with cooling capacities from 120 kW to 1800 kW. They are built on the basis of Bitzer screw compressors (Germany). All components are produced by the leading European manufacturers. The use of water-cooled condensers makes it possible to achieve larger cooling capacities with less energy consumption than when using air-cooled condensers. Their main fields of application are: engineering industry, chemical and food industry. They can also be used in air conditioning systems. Their main advantages are reliability, compactness with high cooling capacity, and low power consumption. Main fields of application:

  • central cooling systems
  • air conditioning systems of buildings
  • chemical industry
  • food industry

General Information

1 or 2 pieces semi-hermetic compact screw compressors are used according to capacity. Screw compressors as it’s characteristics can operate without maintenance need for a long time. Maintenance of the screw compressors are quite simple because of the less amount of the moving parts in it. Screw compressors are equipped with discharge shut-off valve, check-valve that prevents to return back of the refrigerant from the discharge line, oil level switch, oil sight glass, oil separator, oil filter, crankcase heater, capacity control solenoids, vibration dampers,motor protection device and temperature sensors(PTC).

Manufactured in Shell and Tube form. Special profiled tubes providing heat transfer are made of cooper-nickel, tubesheets and covers are made of resistant corrosion material, other parts made of carbon steel. Cr-Ni material can be used for tube sheets and covers on request.

Direct expansion evaporator is manufactured in Shell & Tube form and special high efficient copper tubes are fixed to grooved steel tubesheet holes with tube expander method. It’s allowed to maintenance and clean up because of the removable tube bundle. Evaporators are in conformity with EN 14276-1 and EN 13445 standarts and designed for chilling water .External surface of evaporators and suction lines are insulated with insulation material with suitable thickness.

The panel is designed to IP54. To operate the Unit automatically and securely, the panel is composed of two different section. The first section is power section and the other one is control section. The panel is equipped with enough number of contactors, thermics,fuses and on-off switchs. The panel and wiring are in conformity with EN 60204-1 standart.

Microprocessor control system is used on the Unit. By means of this; entering and leaving water temperatures,refrigerant pressures on the suction and discharge lines, occured superheat temperature, operating times of compressors, all faults occured on the system and all alarm history can be seen on the digital screen and also capacity control can be made easily. Besides the operating times of each compressor is balanced automatically and optimum efficient operation of the Unit is provided.

To operate the Unit automatically and securely; electronic expansion valve, drier-filter, sight glass, relief valve, flow-switch, high-low pressure switch and shut-off valves are included.
