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.
■The cooling capacity resolution in the low-load
range has been improved through optimal control
of the compressor and electronic expansion valve.

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.
Higher durability for long-distance transportation
■Auto tuning function
This function substantially cuts the time taken for
adjustment during trial operation by automatically setting
the gain when oil temperature control is not stable in the
factory setting status or when optimization is required.
■The specifications for withstanding vibration during transport
have been upgraded to reflect actual transportation conditions.
Five types of semi-standard specification units in addition to
the standard type to achieve shorter product delivery terms
With heater With tank
With breaker
■999-hour timer function (ON timer)
The operation start time can be set from 0 to 999
hours in one-hour units.
Different
voltages
Compliance
with CE
New functions for ease of use
■Preventive maintenance function
●A warning signal is output to notify that maintenance is
required when the air filter or condenser becomes clogged.
●If the thermistor fails (out of control), emergency operation is
possible by selecting another operation mode.
This function minimizes the factors of line stoppages.
Easy monitoring of operating status
■The room temperature, inlet and outlet oil temperatures and other internal
data can be monitored at a personal computer using Hybrid-Win*.
This data can be displayed collectively, making it easy to grasp the
operating status.
Improved operability/maintainability
■The control panel has been revamped. Data is now displayed
in an easier-to-understand format with more digits space.
The power consumption is also displayed (new function).
■The newly adopted plug-in terminal block has enabled
tool-less connection of signal cables (simple connection).
*Hybrid-Win is a software tool for monitoring the internal status of the unit using a personal computer.
You can download the tool and its instruction manual free of charge from
the website (http://www.daikinpmc.com) after registering as a user.
*The communications cable and the monitor harness must be purchased separately.

【Refrigerating cycle】
A：Refrigerant gas is converted into compressed gas at high temperature and high pressure by a compressor so that gas can be easily cooled and liquefied by a condenser.
B：In the condenser, the gas at high temperature and high pressure made in the compressor is cooled with air and converted into liquid at high temperature and high pressure.
C：The pressure reduction mechanism reduces the pressure of the liquid at high temperature and high pressure and converts it into liquid at low temperature and low pressure
by squeezing it so that it can be easily evaporated in a cooler.
D：In the cooler, liquid at low temperature and low pressure made in the pressure reduction mechanism removes heat from oil, evaporates（cools oil）,
and is converted into gas at low temperature and low pressure.
E：The bypass mechanism controls the cooling capacity at low loads by adjusting the volume of gas at high temperature and high pressure supplied to the cooler.

Note）*1. The cooling capacity represents the value at the standard point
（inlet oil temperature: 35℃, room temperature: 35℃, oil for use: ISO VG32）
.
The tolerance of the product is approx.±5%.
*2. Be sure to use a commercial power supply for the power source. The use of an inverter power supply may cause burn damage to the unit.
The voltage fluctuation range should be within ±10%. If the voltage fluctuation range is more than ±10%, please consult us.
*3. There are three types of different voltage specifications depending on the power source: −046, −047 and −048 units. −047 and
−048 units deal with the different voltage by featuring a transformer.
The main circuit voltage is the transformer’
s secondary side voltage of 200 VAC, 50/60 Hz.
(−046 units have no transformer and therefore have the same external dimensions and mass as standard units. Their main circuit voltage is 220/230 VAC, 50/60 Hz.)
*4. The machine temperature synchronous thermistor optionally available is required for this function.
（Refer to Page 19 for details.）
*5. The MSDS
（Material Safety Data Sheet）of refrigerant R410A is attached to ーC type.
*6. Electric component box ingress protection: IP54 or equivalent (However, use piping conduits etc. rated at least IP54 at wiring ports.)
*7. The specifications for withstanding vibration during transport are those of a standard unit.
*8. The molded-case circuit breaker is not supplied with this product. Please prepare it by yourself.
*9. The yellow line on the tank oil level gauge shows the highest oil level and the red line the lowest oil level.

Notes for installing external piping
If the external pressure loss（site piping resistance）
exceeds the specified use range, there may occur
phenomena such as abnormal noise of the pump（relief
noise, noise of cavitation）
, decrease of cooling capacity
and control failure of oil temperature. Keep the external
pressure loss within the specified use range.
●Relationship between oil flow rate
and external pressure loss
An AKZ 9 series Oil Cooling Unit incorporating a pump of the
circulation type has the characteristics shown below. When the
external pressure loss (△p) is 0.5 MPa or less, the rated flow rate
(Q0) is achieved, but when the external pressure loss exceeds 0.5
MPa, the flow rate becomes lower than the rated flow rate.
1. Suction-side piping
Keep the suction vacuum pressure within the range
between -30.7 and 0kPa.
The use of a suction filter of 100 to 150 mesh is
recommended.
2. Discharge-side piping
Keep the pressure loss of the discharge-side piping at
0.5 MPa or less.
3. Do not install a stop valve on the suction or discharge
side. When a stop valve must be installed on the
discharge side out of necessity, use a 0.5Mpa relief
valve along with the stop valve.
4. Calculation of piping resistance
Determine the oil piping size by calculating the piping
resistance according to the following equation:
Good example
Circulation volume or flow rate Q（L/min）

Method of selection of Oil Cooling Unit
Unit conversion formula ● 1kW＝860kcal/h
1.Select Oil Cooling Unit having a cooling capacity 20 to 30% larger than the heat release value from the
machine tool.
2.Since the cooling capacity of Oil Cooling Unit varies with the change of liquid temperature（inlet liquid
temperature）and room temperature, it is necessary to clarify the liquid temperature and room temperature
conditions to select appropriate Oil Cooling Unit.
3.Three methods are shown below as a guide for estimating the heat release value from the machine tool.
For determining the heat release value eventually, it is necessary to conduct tests and determine the
exact heat release value for selecting appropriate Oil Cooling Unit.
