A filter drier protects the system from moisture and debris, and the unit’s top-discharge design improves airflow while reducing operating noise levels to as low as 74 decibels. The control panel is easily accessible for quicker serviceability, and the unit is compatible with most cooling thermostats. A galvanized steel cabinet with baked-on powder coat finish provides protection against corrosion and weather hazards.
