The Water-cooled chiller "H series" with improved efficiency and functionality by several advanced technology. This series with the world's best standard A-type screw compressor and newly designed shell and tube heat exchanger that have powerful cooling ability, low noise, low vibration, high efficiency and high reliability is the perfect answer to all your need!!
Enhanced Line-up ~up to 570 HP~ Top Class High COP High-Perfomance A-type Screw Compressor Highly Reliable Shell and Tube Heat Exchanger Precise Capacity Control Technology Excellent Control Function
Product Series RCUG-WHYZ(-E) Nominal Capacity Range (50Hz) 130 kW to 1,758 kW 37.0 USRT to 500.0 USRT 111,800 kcal/h to 1,512,000 kcal/h
RCU-WHYZ(-E) Nominal Capacity Range (50Hz) 140 kW to 1,825 kW 39.8 USRT to 519.1 USRT 120,400 kcal/h to 1,569,500 kcal/h
TECHNICAL FEATURES Top Class High COP In the new model series, the power consumption is largely reduced over the current model series due to newly designed high-efficiency cooling system. Also COP is largely increased from 4.42 in the current 100HP model to 5.13 in the new 100HP model.
High-PErformance A-type Screw Compressor ~Newly Designed~ Built-in Cyclone Oil Separator Low oil carrying-out is realized and reduction of heat transfer efficiency is minimized.
High Technology by Internal Manufacture Because all manufacturing processes, from rotor manufacturing to unit assembly, are done internally, exceptional reliability is achieved.
No outside pump is required due to the reliable differential-pressure oil-feeding system. This oil-feeding system, which does not use any electrical mechanism, prevents the compressor from being damaged and maintains long-term stable operation.
Low Vibration, Low Noise Without the conventional demister chamber system, no noise is produced during oil separation of discharge gas. A vibration-proof base is not required for the chiller body thanks to the firmly-secured, low vibration screw compressor.
Highly Reliable Shell and Tube Heat Exchanger ~Newly Designed~
Simple structure and easy for maintenance
Reduced cost and adapted to satisfy various demands
Freeze protection thermostat and other safety devices
Integral and reliable performance
Precise Capacity Control Technology Continuous Capacity Control The temperature of the chilled water outlet can be kept at the set temperature +- 1*C by continuous capacity control, so it is suitable for industrial use.
Excellent Control Function Liquid Crystal Screen Display (Optional Accessory)
Communication adapter provides Communication with RS485 physics connection to BMS
Building Management System (BMS) Hitachi uses Building Management System through LONWORKS(r). For chiller air-conditioning, Hitachi provides its own central station system. No complicated works is necessary.
