Centrifugal Chillers
Hitachi introduces new higher-efficiency HFC134a centrifugal chillers.
Please select standard type(14% improvement over the conventional models) or
higher efficiency type(22% improvement over the conventional models) to consider
your usage or space. These efficiency improvements have been achieved by our
advanced technology producing reduced flow loss of HFC134a refrigerant gas,
lowered energy loss in the rotating body and the motor's electrical circuits,
and by the use of a 2-step economizer cycle.

Key Benefits
| |
| 1. Ozone Layer Protection and
Global Warming Prevention |
|
 |
| -Use of HFC134a refrigerant having an ozone depletion
potential of zero. Energy saving with higher-efficiency centrifugal
chillers. |
| 2. Consistent Down-Sizing and
High Efficiency |
|
|
| -High-pressure HFC134a refrigerant enables downsizing and
weight reduction of the rotating body components in comparison with the
conventional low-pressure CFC11 or HCFC123 refrigerant types.
Consequently, the energy loss caused by rotation can be reduced for
consistent downsizing and high efficiency to be achived. |
| 3. Energy Saving Run Throughout
The Year |
|
|
| -Hitachi's unique capacity control mechanism allows
energy-saving run throughout the year by stable capacity control in a
wide range. |
 |
| 4. Microcomputer Panel Provides
Exact Operational Status. |
