Hitachi Industrial Equipment Systems 2-stage DSP-G 22/30/37kW
Hitachi Industrial Equipment Systems
Two-stage DSP-G 22/30/37kW supplying oil-free air for Class Zero.
Improvements in basic performance and control capabilities have achieved further energy savings. - [Approximately 7.3% increase] Increased air discharge volume of 37kW Through the development of a new air end that optimizes gaps and reduces pressure loss, we have achieved greater airflow and higher efficiency. - [Approximately 280,000 yen annual savings] Improved energy efficiency By enhancing the performance of the air end and increasing the efficiency of the permanent magnet motor, we have reduced electricity costs compared to conventional models. In the new model, under full load, energy efficiency has improved by up to 6% with variable speed drives and up to 5% with fixed speed drives. - [Approximately 130,000 yen annual savings] New feature FI control (deceleration unload control) F type (fixed speed machine with permanent magnet motor) The F type demonstrates further energy-saving performance through FI control (deceleration unload), which is an evolution of the conventional I-type control. Compared to the traditional I-type control, it enables reductions in electricity costs. For more details, please contact us.
