Semi-hermetic ammonia inverter refrigeration unit 'iZN/iZSN series'

40% increase in cooling capacity with inverter boost! A new proposal for combating global warming.

The "iZN/iZSN series" is a screw refrigeration unit that features energy-saving (low power consumption) performance, utilizing inverter control combined with KOBELCO's unique capability enhancement technology, and is compatible with the natural refrigerant NH3, which does not negatively impact global warming. By controlling the inverter's rotational speed, the refrigeration capacity can be adjusted continuously, preventing excessive cooling and demonstrating outstanding energy-saving performance. Additionally, the unloading that was traditionally performed by a piston valve is now controlled by the inverter's rotational speed, allowing for appropriate operation according to the load, which enables significant energy savings. 【Features】 ■ Full lineup of semi-hermetic ammonia inverter refrigeration units ■ Outstanding energy-saving performance through inverter control ■ 40% increase in refrigeration capacity due to inverter speed-up ■ Semi-hermetic design with a new structure ■ No need for stop intervals due to the soft start mechanism *For more details, please refer to the PDF materials or feel free to contact us.
