1 The high static pressure system especially suits for large air-flow space. Full-fresh-air realizable . ● Various indoor units with fresh-air enthalpy control make the full-fresh-air and energy saving operation automatically. ● The high static pressure system make the long distance and large capacity forced-draft blow flexible. Convenient for its super long pipe designed. ● The add-humidity and filter facility and auxiliary PTC electric heating are selectable. 2 Long pipe, higher fall The proprietary oil separator. accumulator and high efficiency oil cycling technology ensure to bring refrigerant long distance. The max length of refrigerant pipe can reach 50m and 30m for its max fall. The outdoor units can be unified installed on the roof of the building. 3 Various and flexible controlling ● By LCD display remote control ,you can operate the indoor units separately and choose some additional functions such as add-humidity facility, auxiliary PTC electric heating facility, enthalpy control and filter washing alarm etc. ● Power on or off automatically by time control. ● Concentrated management. 4 Choose freely ● The indoor units can choose Wall-Mounted or Cabinet. ● The adoption of fresh-air enthalpy control by the fresh air side can make the full-fresh-air or min fresh-air energy saving operation automatically according to the change of the outdoor enthalpy. 5 Proprietary technology ,reliability and stability ● The indoor and outdoor units both have a set of pipe for changeable refrigerant flow control .Electronic expansion valve metering, reverse defrosting without stop ,strong heating. ● The outdoor units have self-diagnosis function for convenient repair. 6 Long life service ● The adoption of scroll compressor ensures the operation high efficient and reliable. ● The outdoor units have long service life for its de-erosion treatment. 7 Especially suitable for large room space
