Features

1. 1. Various products and wide application
   The series of Rooftop units include many different specifications which can completely meet the demand of home and
   commercial places and offer you a comfortable and pleasant environment.
   2. Complete air system, simple and hygiene, less components, easy maintenance
   The flexible and concise design makes the maintenance very simple. Disassembling several bolts from any side of the unit
   can repair any part of the unit.
   3. Microcomputer intelligent controller can reach four control modes: cooling, dehumidifying, and ventilation. It also has
   the functions of timing on-off and failure display.
   4. Excellent performance
   World well-known brand of main parts are used. To guarantee the rational match of the unit, strict performance testing
   is done. Besides the unit runs steady and the vibration and noise are effectively controlled by the use of multi-vane pitch
   centrifugal fan, world-known high efficiency compressor and the elaborative-designed controller, motor, etc.
   5. Quiet operation and Convenient maintenance
   Reach the lowest noise of the a/c room. The a/c units are placed far from the a/c area which meets the demand of indoor
   low noise to the greatest degree. The adoption of high efficiency and low noise centrifugal fan makes the quiet operation
   come true

Free cooling logic:

1. When it is cooling:
   a. When indoor room temperature (temperature set) – outdoor temperature ≥ 4 ℃，fresh air damper is 100% open,
   and return air damper is 100% closed，only the evaporator fan is running to blow air into room;
   b. When 0 ℃ ≤ indoor room temperature (temperature set) – outdoor temperature< 4 ℃ ，both fresh air damper
   and return air damper are closed, and the unit is not running;
   c. When indoor room temperature ( temperature set) – outdoor temperature < ０℃，the return air damper is 100%
   open，and fresh air damper is 100% closed，then the compressor, condensing fan and evaporator fan will work normally
   to blow cool air into room.
2. When it is heating:
   It operate in similar way as for free cooling.

Optional heat recovery

Available with a hygroscopic or non-hygroscopic rotor for recovering and transferring
heat energy from the exhaust to the supply air streams.

Optional filter

G3 aluminium filter is standard, optional preliminary, medium filter are
optional.

Optional supply air outlet and return air inlet at the unit bottom

It is optional to have the supply air outlet and return air inlet at
bottom.

Optional MEPS efficiency

It is optional to have the units with efficiency as per MEPS standard.
