1. Features
High capacity of cooling and heating, and energy saving.
Thin size, even can installed at limited place.
All round steel shell, for high quality protection of transportation.
Convenient installation, hidden in the ceiling, unit installation is not hindered by the location of
lighting fixtures or room structure.
Air inlet and outlet flanges are standard and easy for duct connection.
Multi diffusers from one indoor unit supply airflow to multi rooms at the same time. The unit is
suitable for various applications where there are many rooms or halls, such as restaurants,
connect halls and hotels.
Highly efficient scroll compressor, with thermal protectors to prevent motor overheating.
