Dalgakiran EBHV Series

Dalgakiran EBHV liquid chillers are air-cooled freon chillers with cooling capacities ranging from 120 kW to 1600 kW. They are built on the basis of Bitzer (Germany) or Hanbell (Taiwan) screw compressors. All components are produced by the leading European manufacturers. The microprocessor control system and the ability to adjust the compressor capacity allows users to control all the necessary operating parameters and save energy. Chillers of the EBHV series are specially designed refrigeration equipment for industrial purposes. They are designed for cooling thermoplastic machines, extrusion lines, crushers, gearboxes, and can also be used in air conditioning systems. Their main advantages are reliability and performance depending on operating conditions.

General Information

1 or 2 pieces semi – hermetic compact screw compressors are used according to customer request. 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). Required power supply is 3 ph, 400 V, 50 Hz.

Air cooled condensers are manufactured by pipes and aliminum fins. Current overload protected, high efficient direct drive axial fans which have noiseless bearing are mounted on the Unit to provide condensation of the refrigerant.

Direct expansion evaporator is manufactured in Shell & Tube form and special high efficient copper tubes are fixed to 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 and glycol brines. 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. Required power supply is 3 ph, 400 Volt, 50 Hz.

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 condenser fans are controlled automatically depending on the ambient temperature and the operating times of each compressor is balanced so 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, low and high pressure switches and shut-off
valves are included.
