Air-cooled chiller Matrix Advance (large capacity type) – Hitachi Global Life Solutions Inc.


Air-cooled cold screw chiller unit with improved energy efficiency and control functions

Significant reduction in annual power consumption.

(In the case of a 100 horsepower equivalent, approximately 19/22% reduction (50/60 Hz) compared to conventional models.

Product Features
Large-capacity, modular type
Installation workability is the same as that of existing conventional models
Since it is an integrated unit equivalent to 80, 100, or 120 hp, when renewing from an existing conventional type (integrated type) equivalent to 80, 100, or 120 hp, water piping connection work and wiring work can be done in the same way as with the existing unit (2 water piping connection cycles and 1 wiring connection system). Compared to units equivalent to Matrix Advance 40, 50, and 60 hp, on-site work can be saved.

Module control function
Module control is possible when multiple units are installed.
Module control function is provided as standard equipment. A dedicated controller for controlling the number of units is not required (remote operation command input is required). Combined use of compressor operation capacity control and chiller unit operation number control stabilizes water supply temperature and reduces pump transfer power (when the chiller unit and pump are one-to-one).

Up to 8 modules (max. 960 hp)*1 can be connected by module transmission, allowing for installation (replacement) in large-scale heat sources.

1 Use the same capacity combination for unit number control. The compressor operating capacity between cycles must be the same.
Reliable and proven “continuous control” screw compressor
Features of Screw Compressors
Regular maintenance is essential to reduce the risk of sudden breakdowns and ensure stable operation of equipment.
Screw compressors can be overhauled (disassembled and serviced) for planned preventive maintenance.
The overhaul cycle of the compressor has been extended from 24,000 to 40,000 hours for the conventional compressor (compact type AZ5*1). Maintenance costs are also reduced.

Overhaul cycle: 40,000 hours of operation
Refrigeration oil replacement and various inspections cycle: 2 years*2
1 AZ5: Products released until March 2016
2 If refrigeration oil cannot be replaced, overhaul should be planned every 5 years.
● “Continuous control” specification enables highly accurate outlet water temperature control due to stepless control. In addition, “continuous control” without inverter does not generate harmonics from the compressor because the operating capacity is mechanically varied.

More smiles to life for one and all.
