Big duct

GREE Big Duct Inverter Series is a high-performance ducted air conditioning system engineered for applications that require High External Static Pressure (High ESP) and consistent, long-distance airflow distribution. Designed to provide maximum flexibility for ductwork installation, it is an ideal solution for large spaces and projects with complex air distribution requirements. Equipped with advanced Inverter technology, the system delivers stable operation while significantly improving energy efficiency.

The series uses R410A refrigerant and is available in six capacity options ranging from 20, 25, 30, 38, 48, to 57 kW, making it suitable for a wide variety of applications, including large residential properties, commercial buildings, and light industrial facilities.

To simplify servicing, the unit features Easy Maintenance, allowing convenient access for inspection and maintenance. Its High ESP capability ensures reliable airflow performance even in long or complex duct systems, while Wide Voltage Startup enables stable operation under fluctuating power conditions. The integrated Self-Diagnosis function quickly detects and displays system faults, reducing maintenance time and improving service efficiency.

The system is also equipped with a High-Quality Motor for powerful, consistent airflow and long-lasting performance. Its Strong Outdoor Unit is built to withstand harsh environmental conditions and is capable of operating reliably in extreme ambient temperatures. In addition, the Comprehensive Protection System enhances operational safety, safeguards key components, and extends the overall lifespan of the unit, ensuring dependable performance for years to come.
