Features
Dew point temperature energy saving mode switching.
In addition to a pressure dew point of 10 °C, 18 °C also possible. Wide ranging energy savings possible during high temperature periods. Also prevention of condensation formation due to inside/outside temperature differences means reduced installation costs for insulation etc. And added functionality for the pressure dew point setting to track the outside temperature and make automatic adjustments. Thanks to this, troublesome manual adjustments of the pressure dew point are not needed during seasonal changes. (Outside air temperature tracking setting switching function available on RAXE4900 models and above.)
The dew point will go below the selected setting (10 °C or 18 °C) if the load (air flow, intake air temperature etc.) is too low.

Up to 60% energy savings possible (patent under application)
Orion's exclusively developed "Inverter Compressor Frequency PID Control" and "electronic expansion valve closed loop PID control for optimized refrigeration cycle control" achieves impressive energy savings compared with our previous RAX series (CCV controlled) models even under normal operating conditions. Furthermore, maximum energy savings of up to 60% can be achieved at a pressure dew point setting of 18 °C. (Max. 53% for RAXE4900)

(RAXE2300A-W)
Suitable for Low Pressure Applications (0.54 MPa standard)
For low pressure needs, designed standard pressure changed from 0.69 MPa to 0.54 MPa. No equipment upgrades needed in order to deal with low pressures. (RAXE2300~4900 models)
Same power capacity under 50/60 Hz
Thanks to inverter control, the same dehumidification is achieved in 50 Hz and 60 Hz regions, so high-end models selections are not required for 50 Hz locations.

Can Operate Continuously Even Under High Loads
"High Load" refers to one or more of the following conditions: ambient temperature, intake air temperature, air pressure, air flow rate, etc. Through our unique control you can expect continuous operation even during unexpected periods of high load, and our self-regulating control helps to keep the product running while avoiding overload-related shutdowns. (There are cases where, depending on the operating environment, the dew point temperature may rise.)
Function Choices Available to Best Suite Your Operating Environment
The design specifications built into every order-made product can be selected at the initial trial-run of the product in order to best meet the user's needs and target operating environment.
Enhancements from Efforts to Make Products Easier to Use are Built In
- The dew point temperature and error-codes are displayed on the easy-to-use digital display operation panel. (The dew point temperature is calculated based on the air cooling temperature.)
- If by some chance there is any kind of trouble, a single glance at the error code can help to easily diagnose the reason for operation stopping.
