Features of
CN-eco type equipment (energy-saving model) |
| |
By the combination
of two advanced technologies, (1) and (2), N2 gas generation
per unit power increase up
to 42% compare to the conventional model.
| (1) |
Improvement of
the unit consumption achieved the "industry-highest level."
| Newly
developed highly efficient adsorbent
(Molecular Sieving Carbon)
improved the separation efficiency
of N2 significantly. (See
"PSA" in the figure on the
right. Increased by 18%.) |
|
| (2) |
Further improvement
of the unit consumption by combining with VS model compressors.
The
advanced Kobelion-VS inverter compressor,
which achieved the highest level of
energy saving performance, supplies
the feed air for the PSA efficiently,
and increased the N2 gas
generation per unit power consumption
substantially.
(See "VS model" in the figure
on the right. Increased up to 24%. |

Energy saving
Output power (kW) reduction
Compared with conventional models, by the
combination of (1) and (2), the power consumption
will be reduced by up to 30% for the
same N2 gas flow rate.

Power consumption reduction in respond
to the turndown use of N2 gas(power
consumption reduction during turndown operation)
Combination of the following two technologies,
(1) and (2), reduces the power consumption
further in respond to the less use of
N2 gas from the rating volume
(at turndown operation).

|
|
|
(1) New control method of the adsorption
and desorption cycle time according to the N2
gas flow rate.
- By the control of the adsorption and desorption
cycle time for the N2 gas flow
rate used, rather than the conventional
control method by the pressure in N2
gas holders, provides further energy saving
at turndown operation.
- Stable, low load continuous compressor
operation is ensured regardless of the capacity
and pressure difference of N2
gasholders. |
| |
(2)
An advanced inverter compressor (Kobelion-VS
model) with high energy efficiency
[Energy-saving technologies used in the
Kobelion-VS model]
- Reduces the mechanical loss thoroughly
by connecting the screw compressor with
the motor directly.
Reduces the energy loss (heat generation)
by mounting a high-speed permanent magnet
motor (IPM motor)
- Optimizes the energy efficiency, including
the cooling fan, by mounting a special inverter. |

Space-saving
By the high efficient absorbent, new model
require the smaller cabinet and one rank
downsized compressor comparing with the
conventional model.
It achieves in a compact, space-saving
N2 gas generator, compared with the conventional
model (CN type).
(In the example on the right, the installation
space and the weigh are reduced by 28%
and 38%, respectively, for the same flow. These figures may change depending
on the model, or by reviewing the design
in the future. The model numbers in the figures are applied for Japan.) |
