AKC liquid cooling system Series 9 (Discontinued model)

High-precision inverter-controlled oil cooling (circulation of the coolant)

Outstanding energy savings

The compressor is equipped with a highly efficient original Daikin IPM motor. High energy savings are achieved thanks to the inverter control technology, which is based on our experience in air conditioning technology and the refrigerant R410A, which has a high COP value. (Approx. 30% energy saving compared to Series 8)

Easy maintenance

The design of the evaporator heat exchanger has been improved to increase durability against clogging. In addition, the evaporator coil is easy to dismantle and clean.

Greater resistance to oil mist and dust

The protection class of the switch box has been improved to IP54, including the use of sulphur-free parts.

Existing functions:

Refrigerant gas leak detection function. If a refrigerant gas leak occurs (cooling disabled), alarm signals are issued. Prevents damage to the machine and machining errors.
Temperature warning function. A warning signal can be emitted if the target liquid or air temperature is outside the freely selectable setting range.
Autotuning function. This function minimizes the setting time for trial operation by automatically setting the increase if the liquid temperature control is not stable with the factory setting or if optimization is required.
999-hour timer function (ON timer) The operating start time can be set in a range between 0 and 999 hours (in units of hours).

Technical data

Cooling capacity: 3.5 - 5.6 KW
Refrigerant: R-410A
Supply voltage: 3-phase AC; 200 - 220 V 50/60Hz
