About This Product

■Summary

Improved rated cooling COP for all models. Achieves high energy savings by improving performance during low-load operation. Furthermore, module control functions are standard equipment.

■ Hitachi's new technology realizes high rated cooling COP

The rated cooling COP has been improved for all models by installing a high-efficiency inverter scroll compressor and improving the refrigeration cycle and water side heat exchanger.

■Low load performance improvement path structure

Adopts a heat exchanger path structure that maximizes heat exchanger performance during low-load operation. After dividing the heat exchanger into upper and lower stages, the flow path becomes narrower toward the downstream of the heat exchanger, increasing the refrigerant flow rate and improving the heat transfer coefficient. Cooling capacity has been increased to improve energy efficiency.

■Σ (Sigma) shape heat exchanger

Two-fan structure to improve efficiency during low load operation. We have adopted a Σ (sigma) shaped heat exchanger that maximizes the effectiveness of this two-fan structure, improving heat exchanger performance.

■Long bell mouth structure

The multi-stage expansion structure greatly reduces fan input by smoothing the flow of air. Furthermore, by adopting a long bell mouth, air leakage is suppressed and high efficiency is achieved over a wide operating range.

■Improved low-load operation efficiency

The oil distribution method to the compressor mechanism has been improved (optimized oil supply amount) to suppress excess oil and improve efficiency in the high-speed rotation range, while improving sealing performance during low-speed operation (low load). We also aimed to improve efficiency during operation.

■Can control up to 8 modules in 1 group (maximum cooling capacity 400kW)

Equipped with module control function as standard. A dedicated controller for controlling the number of units is not required. (It is necessary to input operation commands remotely.)

■Number of units control function

Operate the number of machines commensurate with the load.

■Rotation function

The operating time of each module will be monitored and rotation will be carried out according to the operating time.

■Operation at abnormal stop

You can avoid the risk of complete stoppage. Disconnect the module that has stopped abnormally from control and continue operation with the normal module.

■Can be transported using an elevator

It can be transported using an 11-seater elevator. (Excluding type 500)

■Built-in active filter for harmonic countermeasures available (can be modified) (75 and 125 types excluded)

To deal with harmonics, we have prepared a built-in active filter that can be installed inside the chiller unit. (It will be shipped built into the main body.)
