Inverter-controlled refrigerated air dryer RAXE series

Orion Machinery/Air Dryer. Energy-saving mode switch for dew point temperature, achieving up to 60% energy savings.

■ Energy-saving mode switch for dew point temperature. In addition to a dew point of 10°C under pressure, 18°C is also selectable. This allows for significant energy savings during high-temperature periods. Additionally, it is possible to prevent condensation caused by the difference in outdoor temperature. A function has been added to automatically change the dew point setting under pressure in conjunction with the outdoor temperature (for models RAXE4900 and above). ■ Achieves up to 60% energy savings. Through the unique development of "frequency PID control of the inverter compressor" and "continuous PID control of the electronic expansion valve for optimizing the refrigeration cycle," significant energy savings have been achieved even during normal operation compared to the conventional RAX series (CCV control). Furthermore, when the dew point under pressure is set to 18°C, up to 60% energy savings are possible (RAXE4900 model achieves up to 53%). ■ Responds to low-pressure needs (based on 0.54MPa). In response to low-pressure needs, the design standard pressure has been changed from 0.69MPa to 0.54MPa. There is no need for a rank upgrade in model selection at low pressure (for models RAXE2300 to 4900). ■ Continuous operation possible even under high load. Thanks to unique control, continuous operation is maintained even during unexpected high loads, making it difficult to stop before safety devices activate through self-protection control. ■ Inverter control allows for the same capacity at 50Hz and 60Hz.
