|
|
 |
| High reliability |
| Environmentally friendly |
| Various applications |
Diesel engine generating system / Gas turbine generating system / Steam turbine generating system / Hydraulic turbine generating system |
|
|
Co-generating systems |
|
The global resources are finite. Co-generation system recovers heat energy in the exhaust gas from the diesel engines which was wasted in vain in the past and utilizes it for air-conditioning etc.
The system also contribute to low pollution and energy conservation program as well as to achieve preservation of the environment and preservation of global warming by reducing CO2. |
 |
Co-generation system with a gas engine fueled by city gas(13A) which is recognized as clean energy.
|
|
 |
| Out door type(Gas engine driven) |
A compact and low noise gas Co-generation system by adopting package type cubicle.
|
|
 |
| Out door type(Diesel engine driven) |
A high efficiency diesel Co-generation system with diesel engine fueled by diesel oil.(Low pollution and low noise)
|
|
 |
A compact gas Co-generation system packed all necessary devices such as a generator panel, an auxiliary panel, an exhaust gas heat exchanger, a hot water circulating pump and a three way valve as well as a gas engine and a generator in one package.
|
|
|
|
| All in one type |
| Low pollution, energy conservation |
|
Combined use as an emergency generating system |
| Various fuel |
Gas Co-generation system / Diesel Co-generation system |
|
| Various application |
Hotels / Hospitals / Shopping centers / Aquariums / Office buildings / Factories |
|
|
Emergency generating systems |
|
Emergency generating systems are provided to protect livings of people from an unexpected blackout caused by the disasters such as fires and earth-quakes.
The generating system starts automatically in case of blackout condition and supplies electricity to the equipment such as safety devices and fire fighting apparatus, etc. |
 |
| Built-in microcomputer type |
Wholly automatically controlled by microcomputer from detecting blackout condition, starting engine and supplying electricity to detecting recovery of electric power and stopping engine.
By adopting package type cubicle, low-noise type generating systems are realized and more over, installation work is very easy and can be installed anywhere, because of the cubicle being out door type.

Specialized Power Supplies (Rotary Frequency Changers,MG Sets) |
|
Nishishiba’s specialized power supplies provide ideal solutions for a wide range of situations. For example, they can be used as a test power supply for electric motors, fans, pumps and other equipment. Also among Nishishiba’s product portfolio are variable-frequency and variable-voltage power supplies, which are essential when you need a frequency or voltage different from that of the commercial mains, such as when a 60-Hz vessel anchors at a harbor in a 50-Hz region. |
 |
| Type 1: |
Synchronous Motor-Synchronous Generator (SM-SG) Set |
The SM-SG set converts the frequency of a power supply from 50 Hz to 60 Hz, or vice versa. It is mainly used by ships.
| Type 2: |
Induction Motor-Synchronous Generator (IM-SG) Set |
The IM-SG set changes the frequency of a power supply by controlling the speed of induction motor with an inverter,whitch means SG output frequency is changed freely from several tens to several hundreds.The voltage is also adjustable between several ten% and 100%.
| Type 3: |
Short-Circuit Testing Applications (SM-SG) |
Type-3 SM-SG sets can be used for short-circuit testing of electric equipment.
|
|
|
|
| Provides very clean and distortion free waveforms that can not be obtained with stationary power supplies, and thus allows accurate measurement and emits hardly any noise. |
| Highly reliable and has a longer service life than stationary power supplies. |
|
Can be customized to your output voltage and frequency range specifications. |
