High Efficiency Centrifugal Chillers

GFG-SSC Series (Super High Efficiency Type)

GXG-S Series (High Efficiency Type)

GSC-S Series (Compact Type)

1,055 ~ 7,032kW (300~2,000USRT)

• 2 stages compression cycle with newly developed economizer (cyclonic system), increased the refrigerating cycle efficiency
  
• High-performance heat exchange tubes with optimal structure design increased efficiency of heat exchanger
  
• 3 dimensional blade impeller (2 stages) with semi-hermetic design, optimally designed diffuser with vane increased compressor efficiency     
• Direct refrigerant cooling of lubrication oil in oil cooler without cooling water piping increases reliability                    

Screw Type Water-Cooled Chiller

Latest Development of Screw Compressor

• highly reliable HITACHI Two-Pole Motor, Built-in Oil Separator (cyclone oil separator), Oil Slight Glass and Heater, High precision Twin Screw Rotors, Suction Filter

Continuous Capacity Control

• advanced electronic controls to position the infinitely variable slide valve within each compressor
  
• Exact load control and accurate chilled water temperature without the need for expensive inverters
  
• 15~20% energy saving is achievable because the cooling load can be more closely matched, takes advantage of high efficiency part load performance

Plate Type Heat Exchanger

• able to provide improved cooling capacity for R407C
• Higher efficiency due to closer approach temperature
• Less refrigerant are used due to small internal volume
  

High-Efficiency Direct Drive VSD Centrifugal Chiller

GFVG Series (Super High Efficiency type):

1,055 ~ 3,868kW (300~1,100USRT)

GXVG Series (High Efficiency Type):

1,055 ~3,692kW (300~1,050USRT)

• External compact and high performance economizer with cyclonic system contributes for drastic downsizing
  
• High-performance heat-exchanger tubes and optimum structural design enables high efficiency
  
• Direct-drive gearless structure two-stage compressor with high speed motor realizes further improvement of efficiency  at full/partial load
  
• Cost saving is achievable due to the reduction of consumable and moving parts. Less rotating parts reduce the costs of overhauling, lubrication oil, etc. and extend the product life

Water-Cooled Chiller (H-Series)

RCUG-WHYZ (-E): 130 kW ~ 1,758kW

Nominal Cooling Capacity (50 Hz)

RCU-WHYZ(-E): 140kW ~ 1,825kW

Nominal Cooling Capacity (50 Hz)

High-performance A-type Screw Compressor

• Low oil carrying out and reduction of heat transfer efficiency is minimized  with built-in cyclone oil separator
  
• Differential-pressure oil-feeding system  prevents the compressor from being damaged and maintain long-term stable operation
  
• Exceptional reliable due to internal manufacture from rotor manufacturing to unit assembly

Highly Reliable Shell and Tube Heat Exchanger

• Reduced cost and adapted to satisfy various demands
  
• Simple structure and easy for maintenance
