Wide range of outdoor units

Long piping length
The solution supports an incredible piping length of 1,000m and level difference of 110m, making it perfect for large projects.
Long piping length

Duty Cycling
In one combination, any outdoor unit can run as the master outdoor unit to equalize the service life of all units.
Duty Cycling

Back-up Function
In a multiple system, when the master unit failed, any single unit can be set as the master unit, then the remaining units can keep on working. This can be set on main board by DIP switch at site.
Back-up Function

High efficiency oil balance and oil return technology
Four stages oil control technology ensure every outdoor’s and compressor’s oil always keep in the safe level, completely avoid being oil shortage.
High efficiency oil balance and oil return technology

High COP/EER values
The D4 PLUS Series with high efficient digital scroll compressor, DC motor and high efficient heat exchanger, achieve the world’s Top Class energy efficiency. The cooling EER up to 4.29 and the heating COP up to 4.6 in the 8HP category.
High COP-EER values

Digital Scroll Compressor
The digital scroll compressor utilizes axial compliant sealing technology to precisely adjust the axial motion range of the stator scroll pan. And there is an additional connecting by-pass between the suction inlet and the pressure bore at the floating sealing point of axial stator.
