9 AKZ SERIES Circulation type AKZ 9 SERIES RoHS Compliant Features Features Further Evolution of High-accuracy Temperature Control Achieve high energy-saving performance ■Our acclaimed ±0.1℃ oil temperature control has been extended to cover an even wider range. ■Achieve high energy-saving performance with the adoption of a Daikin original IPM motor and R410A refrigerant for high COP characteristics.
Features Functions featured ■The ingress protection of the control box has been upgraded (equivalent to IP54). ■Refrigerant gas leakage detection alarm function An alarm signal is output when the refrigerant gas would be leaked (as cooling circuit failure). ■Oil temperature warning function A warning signal can be output when the oil temperature or air temperature strays outside arbitrarily setting range. ■Electronic components resistant to sulfidization have been adopted.
