1. Product Overview
The Daikin 18 SEER2 ENTRA R32 series single zone inverter wall-mounted systems offer energy efficiency and precise comfort control. These heat pump systems feature streamlined indoor units and quietly compact outdoor units, providing an affordable and cost-saving solution for year-round climate management.
With up to 18 SEER2, 9 HSPF2, and 11 EER2 ratings, these units ensure efficient cooling and heating operations, leading to reduced operating costs compared to conventional systems. The curved contour design of the indoor unit blends seamlessly with various home decors, making it ideal for single room enhancements, areas requiring supplemental heating or cooling, and new additions.
The system allows for adjustable air direction and flow rate, preventing direct airflow onto occupants. It utilizes R32 refrigerant, which is an environmentally conscious choice to replace R410-A.
