1 High quality fan, every fan which installed on the fan coil unit is passed precision adjustment of dynamic balance. Fan runs with low noise and stable working.

2 Using high grade tensile plate, with plastic sprayed on the surface, therefore it is smooth and shiny rusty-proof as well Introducing one-off pressed forming technique, there is no welding line and point deal with heat preservation to assure the tray flat and compact avoiding quadratic leakage.

3 High quality purple copper, with high diathermanous efficiency, tenacity and rigidity characteristic to bear high hydraulic pressure especially, suits super high building use. Distance of fins is improved by computer emulation optimum design with experimental feedback, supply sufficient heat exchange area, smooth airflow and high efficient heat exchange.
