Energy-saving inverter chiller units

Reaction to new refrigerants

All units use the new refrigerant R410A, which is not harmful to the ozone layer.

Implementation of a high energy saving performance

Approximately 20% savings (compared to non-inverter systems of our company).

Implementation of heat control with high precision

Temperature control: ± 0.1 ° C (AKZ series: thermal load: 5-100% stability) (AKZJ series: thermal load: 30-100% stability)

The function for warning with existing oil heating has been added a new and outstandingly good function

• Autotuning function.
• Function for detection of escaping refrigerant gases.
• Timer function for 99 hours.

Execution

AKZ Series (circulation model)

* 1 The cooling capacity shows the cooling capacity with respect to the standard point
(Inlet temperature 35 ° C, room temperature 35 ° C), the fixed emission quantity
of the oil pump and the ISO VG32 oil used. The difference between the products is ± 5%.

AKZJ Series (immersion model)

*2 The cooling capacity shows the cooling capacity relative to standard point oil used
ISO VG32. The difference between the products is ± 5%.

Setting and equipment

(Note) The optional accessories are listed below.

• Sensor for device (cable length 5 m, 10 m)
• Oil temperature control sensor (cable length 5 m, 10 m)
• Extension board for communication with main unit (possible parallel communication, serial communication) [suitable for AKZ568, AKZ908, AKZJ568, AKZJ908]
  *1 E1: AC 220, 230 V 50/60 Hz
  E2: AC 380, 400, 415 V 50/60 Hz
  E3: AC 440, 460, 480 V 50/60 Hz
