• Air purifiers

■ Significant energy savings achieved through energy-saving dew point sensors. ■ Digital dew point monitor enables dew point monitoring and further energy savings. ■ Energy-saving control possible with any dew point setting from -60 to 0°C (under pressure). (Dew point display accuracy: -60°C to +20°C ±3°C) ■ Equipped with a digital dew point monitor. ■ Standard features include dew point alarm output (with two voltage-free contacts and standby sequence) and analog output (DC 1-5V (-80 to +20°C)). ■ Remote monitoring of compressed air quality and dew point is possible.

• Dehumidifier

■Freon-free Air Dryer The heatless air dryer QSQ series removes water vapor from compressed air using a desiccant. Unlike refrigerated air dryers, it can supply freon-free air with a low dew point. The regeneration of the desiccant is achieved by passing a portion of the dried air through it (purge air). ■Energy-saving dew point sensor is standard equipment. (Medium-sized series) ■All functions are displayed with lamps. ■Compact, lightweight, and easy to maintain.

• Dehumidifier

■ 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 enables significant energy savings during high-temperature periods. Additionally, it is possible to prevent condensation caused by the difference in outdoor temperature. A feature has been added to automatically adjust 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 "infinitely variable 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 (0.54MPa standard). 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 even under high load. With unique control, continuous operation is maintained even under unexpected high loads, making it difficult to stop before safety devices are activated through self-protection control. ■ Inverter control allows for the same capacity at 50Hz and 60Hz.
