• Alternative HFC refrigerant, free of fluorocarbons, worry-free on related costs.

The PAU-GR Series uses the alternative HFC refrigerant R1234yf, which is not subject to fluorocarbon emission regulations. There’s no need for recovery/destruction by designated companies or periodic inspections, truly reducing fluorocarbon-related costs

• Greater energy savings with maximum energy efficiency and reduced heat emission.

The PAU-GR Series uses maximum energy efficiency and reduces heat emissions to enhance energy savings. In addition to significantly lowering electricity costs compared to conventional and central systems, the PAU-GR system also reduces heat emissions by up to 87% compared to standard air conditioners.

• All-in-one system with 3 operating modes to support versatile applications.

Three operating modes – Energy Saving Mode, Dry Mode, and Maximum Heating Mode – meet a variety of needs, whether it’s precise temperature and humidity control, cooling and dehumidification, or heating and humidity increase.

• Easy-to-understand information.

In addition to allowing users to quickly check the operating status, the display with intuitive icons immediately shows where an error has occurred and how to resolve it. This enables users to troubleshoot quickly and maintain operational efficiency even when problems arise

• Simple centralized management with IoT connectivity.

The built-in Ethernet communication function (Modbus/TCP) allows easy connection to PLCs, touch panels, or other control devices via the TCP/IP protocol. Integrating the precision air conditioner control units (TCU/ECU) makes it easier than ever to monitor current status values, change settings, manage issues, and perform other operations.
