TWIN SCREW COMPRESSOR TYPE HITACHI WATER-COOLED CHILLERS - ICHIBAN AQUA SERIES

The High-efficiency water-cooled chiller WU series uses a new refrigerant, R407C. Reliability is higher due to a new screw compressor with a cyclone oil separator, Hitachi's unique technology. Many industrial applications are possible due to precise control of water temperature and wide range of operation.

Energy saving with high efficiency
COP is 5.19 on RCUP43WU of the new series, an increase of 18% from RCU50SY3E of the conventional series.

Industry-leading partial load properties
High COP is possible even at minimum load

Plate heat exchangers
Hitachi uses less refrigerant to help protect the environment, such as by using plate heat exchangers.

Hitachi uses R407C
As shown in the drawing, refrigerant R22 and R407C deliver similar cooling performance. The use of R407C makes the size more compact than R134a refrigerant.

A simple structured high-performance new twin screw compressor
Hitachi's new screw compressor has the folowing features:

Low vibration
No exclusive vibration control equipment is necessary due to the low-vibration screw compressor.

Compact and light
As shown in the drawing on the right, the volume, installation space and weight are all reduced, making installation easy.

Decrease holding water quantity
As Hitachi's new type of water-cooled Chillers holds less water, so fewer facilities are necessary

Continuous capacity control
The temperature of the chilled water outlet can be kept at the set temperature ± 1^oC by continuous capacity contro, so it is suitable for industrial use.

Many Applications
Hitachi uses Building Management System through LONWORKS. For chiller air-conditioning, Hitachi provides its own central station system.

  I am Mr.Andre .S Engineering from “ PT.INTI KARYA KARISMA AND CHEMICALS” . Due to we have new project that need chiller 15 ton ref. Specific data are : 1.Temperature out let of Chill water is -20 C 2.Chiller water flow rate to Chiller is 8 m3/hr 3.We prefer to use cooling water for coolant 4.we intend to use environment friendly refrigerant, instead R22. Could you please recommend us about your product that match with our requirement.? And also let me know if you need any information . Regards ... Andre Process Engineering Thaiplastic and Chemical PCL. 0812 8678 3132
