About This Product

■Outstanding energy-saving performance with inverter control Demonstrates excellent energy-saving performance depending on the load

By controlling the rotational speed of the inverter, the refrigeration capacity is controlled steplessly and excessive cooling is prevented, resulting in outstanding energy-saving performance. In addition, unloading, which was conventionally done using a piston valve, is now controlled by an inverter, resulting in optimal operation according to the load, resulting in significant energy savings.

■Quick solutions with iZ monitor Equipped with advanced brain "iZ monitor"

Merely notifying you of an abnormal stop is not enough. Kobelco thought so. The "iZSB/iZαB series" constantly monitors the operating status of the refrigerator using sensors installed in each part. It detects machine abnormalities in advance and sends out warnings before abnormal stops or breakdowns occur, preventing sudden machine downtime. It also has a driving history memory function, which allows you to accurately understand the situation leading up to a problem, which helps in speedy resolution.

■No need for stop intervals due to soft start mechanism

Demonstrates excellent energy-saving performance depending on the load. There is no inrush current at startup, allowing for soft startup. The effects of installing an inverter are also visible at startup. Constant-speed star-delta startup puts a huge burden on the motor, and requires a 10-minute interval between restarts. The "iZSB/iZαB series" uses an inverter for soft startup, so this interval is unnecessary and a quick restart is possible. This allows you to stop operations even if you wanted to do so but were unable to do so, contributing to greater energy savings.
