MIWA ECONO-SYSTEM |
|
| Advantages of MIWA ECONO-SYSTEM |
|
|
| 1. |
Highly
efficient energy savings
Eliminating
wasteful pressure rise by pressure control,
quick and secure compressor group control and
switching operation are achievable |
|
|
| 2. |
Reliable
design free from air down
As
preventive measurements against air down,
predictive operation and two types of start
signals secure the restart interval after
shutdown. |
|
|
| 3. |
Applicable
to any compressors
Any
combinations of compressors of different
types, manufacturers and operating systems are
controllable. Screw compressors, reciprocating
compressors and centrifugal compressors can be
used together. |
|
|
| 4. |
Various
compressor protecting programs are available
Is a
machine-friendly unload lock system with
various compressor protecting programs such as
the restart check and the stop prohibition
check. |
|
|
| 5. |
Equipped
with automatic black out starter as standard
specifications
Automatically
restarts operation even in case of black out. |

NOTE: |
|
1. |
Rotational
operation adopts the first-start and
first-stop system. |
|
2. |
Switching
operation saves energy by fine control that
switches operation with large-sized
compressors to small-sized compressors when
required during rotational operation. |
