• Ethylene glycol solution added to the fluids that can be used

Acclaimed high-accuracy temperature control

• Acclaimed high-accuracy ±0.1°C oil temperature control
• The cooling capacity resolution in the low-load range has been improved by optimal control of the compressor/inverter and electronic expansion valve.
• ±0.1°C oil temperature control realized over a load range from 0% (no load) to 100%.

Specifications

• Cooling capacity:                1,4 - 9,2 KW
• Refrigerant:                         R-410A
• Power supply voltage:         3-phase AC; 380 - 400 - 415 V  50/60Hz

High-accuracy inverter controlled oil cooling unit Immersion type for cutting/grinding fluid (oil)

Acclaimed high-accuracy temperature control

• Acclaimed high-accuracy ±0.1°C fluid temperature control
• The cooling capacity resolution in the low-load range has been improved by optimal control of the compressor/inverter and electronic expansion valve.
• Fluid temperature control of ±0.1°C has been realized over a load range from 0% (no load) to 100%.

Reduced environmental load

• Complies with environmental regulations, e.g. by adopting printed circuit boards with lead-free solder.

Lightweight transformerless 400 V specifications now available

• The dimensions are the same as standard models, so no design changes are needed for different voltages.
• The mass is much lower than that of the 9 Series. (27% reduction)

Specifications

• Cooling capacity:                1,8 - 9,0 KW
• Refrigerant:                         R-410A
• Power supply voltage:         3-phase AC; 200 - 480 V  50/60Hz

High-accuracy inverter controlled oil cooling unit (Circulating type for coolant cooling)

Excellent energy savings

• A Daikin original high efficiency IPM motor is adopted on the compressor. High energy savings are realized with inverter control technology built up through our air conditioning experience and
  R410A refrigerant that has high COP characteristics. (Approx. 30% energy savings compared to the 8 Series)

Easy maintenance

• The evaporator coil design has been improved to give more durability against clogging. It is also easy to disassemble and clean the evaporator coil.

Greater durability against oil mist and dust

• Ingress protection range for the control box is improved, including upgrade to IP54 and adoption of sulfur-free parts.

Functions featured:

• Refrigerant gas shortage detection function. When the refrigerant gas leak status occurs (cooling disabled), alarm signals are output. Prevents damage to the machine and machining defects.
• Temperature warning function. A warning signal can be output when the targeted fluid temperature or air temperature was out of the arbitrary setting range.
• Autotuning function. This function substantially minimizes trial operation adjustment time by automatically setting the gain when fluid temperature control is not stable with the factory setting or when optimization is required.
• 999-hour timer function (ON timer) The operation start time can be set in a range between 0 and 999 hours (in hour units).

Specifications

• Cooling capacity:               3,5 - 5,6 KW
• Refrigerant:                        R-410A
• Power supply:                    3-phase AC; 200 - 220 V 50/60Hz
