Oil temperature warning function AKZ 9 series . A warning signal can be output when the oil temperature or air Higher durability for long-distance transportation temperature strays outside arbitrarily setting range. The specifications for withstanding vibration during transport Auto tuning function have been upgraded to reflect actual transportation conditions. This function substantially cuts the time taken for adjustment during trial operation by automatically setting Five types of semi-standard speci cation units in addition to the gain when oil temperature control is not stable in the the standard type to achieve shorter product delivery terms factory setting status or when optimization is required.

Features Individual With heater With tank Compliance speci cations for With breaker with CE hours in one-hour units. general purpose are set as New functions for ease of use semi-standard types Preventive maintenance function A warning signal is output to notify that maintenance is required when the air lter or condenser becomes clogged. If the thermistor fails (out of control), emergency operation is Easy monitoring of operating status possible by selecting another operation mode. This function minimizes the factors of line stoppages. The room temperature, inlet and outlet oil temperatures and other internal data can be monitored at a personal computer using Hybrid-Win*.
7 Improved operability/maintainability This data can be displayed collectively, making it easy to grasp the operating status. The control panel has been revamped. Data is now displayed *Hybrid-Win is a software tool for monitoring the internal status of the unit using a personal computer. in an easier-to-understand format with more digits space. You can download the tool and its instruction manual free of charge from The power consumption is also displayed (new function). the website ( ) after registering as a user. *The communications cable and the monitor harness must be purchased separately. The newly adopted plug-in terminal block has enabled tool-less connection of signal cables (simple connection).

10 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 lique ed 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.
