Wide Operating Range

MDS system undergo rigorous test to ensure superior

performance. MDS system can run in a very good condi-

tion from -15ºC to 48ºC.

The stage of the art heat-exchanger combining with the

high efficiency compressor promotes rapid exchange

between refrigerant and air, ensuring set temperature to

be achieved faster compared to traditional air-

conditioning system.

Long Piping Design For Flexibility

Piping length between outdoor and indoor unit can be

extended up to 150 meters. The height between outdoor

unit and indoor unit can be extended up to 50 meters. The

height difference between indoor units can be as high as

15 meters. This greatly reduces constraint and offers

huge flexibility in system design.

Better Place Utilisation

MDS uses the single outdoor multiple indoors combina-

tion. This concept has greatly reduced the outdoors units

and enhances flexibility during installation.

Better Solution

Comparing to conventional chilled water

system, MDS required far less equipment.

Boilers, cooling tower are things in the past with

MDS. Thus, MDS is clearly a better solution for

new projects or even retrofit purposes.

Simple Installation

Unique piping joints and simple wiring make it possible to install MDS system quickly and easily.

MDS System

The MDS system operates in a stepless capacity modula-

tion ranging from 10~100%. The modulation will closely

match the demand capacity whereby contributing to high

SEER ratings that no conventional air-conditioners can

achieve.

MDS System

Only a common 2-core, screen cable wire

is required to enable communication

between outdoor and indoors.

The refnet joint is provided by the factory

in accordance with different indoor units,

which will reduce the work force at site and

save you a lot of money.
