Dalgakiran PAKCOLD liquid chillers are air-cooled freon chillers with cooling capacity from 2 kW to 150 kW. They are built on the basis of reciprocating and scroll compressors Copeland (Germany), Bitzer (Germany), and RefComp (Italy).
A high-performance pump and a storage tank of the built-in hydronic module provide the most effective cooling and circulation of the medium to be cooled. Their main fields of application include plastic industry, food processing, metalworking, and chemical industry. Their key advantages are compactness, reliability and simplicity, full readiness for operation, automatic operation.
The Pakcold series chillers are built according to the quality standards ISO 9001: 2000 Quality Management System and are delivered ready for installation. The refrigeration unit is filled with freon and tested at the factory.

General Information
Chassis of the unit is made from steel sheet iron with suitable thickness. It’s designed in speial construction for able to carry weights on it and have dismountable connections. Frame and covers of the unit also made from galvanised steel sheet iron with suitable thickness. All steel sheet parts are painted with oven-dry paint.
Scroll, hermetic or semi hermetic reciprocating compressor is used. Required power supply is 3 ph-400 Volt-50 Hz.
Air cooled condensers are manufactured by pipes and aluminum 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. The unit can be produced with water cooled condenser 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 and glycol brines. External surface of evaporators and suction lines are insulated with insulation material with suitable thickness.
The high efficient axial fan which is directly coupled with the motor is mounted on the device to provide thecondensation of the refrigerant in the air cooled water chillers.
Equipped with enough number of contactors, thermics, fuses and on-off switchs so as to operate the machine full automatically. Required power supply is 3 ph – 400 Volt 50 Hz.
Electronic control system is used on the unit. By means of this entering and leaving water temperatures, operating times of compressor and pump,faults occured on the system can be seen on the digital screen and also optimum efficient operation of the unit is provided.
Mounted so as to provide the water circulation between the chiller and the plant. The pump is chosen according to the pressure loss in the pipeline.
Inside the unit, there is a cylindrical cold water tank which have enough volume. Tank is isolated with suitable material against the heat losses and condensation.
For the machine to operate automatically and securely; drier filter, sight glass, thermostatic expansion valve,solenoid valve,low-high pressure switch, water flow-switch, liquid shut-off valves are included.
