Features

  • High control precision and wide control range 

    Cabinet process 

    Sturdy metal shell, all shells are made of steel plates of 1.2mm or more. Good sealing, lined with heat-insulating and sound-absorbing materials, which can prevent airflow leakage and reduce noise The unit has a hinged front door, which is easy to open and can provide normal maintenance service without providing special tools.

    Scroll compressor 

     Advanced high-efficiency compressor system, using Hitachi or Copeland and other world-renowned compressors; low noise, high efficiency and energy saving, high reliability and long service life; the whole series adopts advanced compressors with high efficiency, few moving parts, prolonging the life of the unit and no liquid strike phenomenon. The compressor is equipped with a phase loss protection device, which can automatically stop the compressor work and protect the compressor motor in case of power loss or compressor overload.

    High-efficiency aluminum heaters can be used

     The most economical choice of air conditioner heater in terms of cost is metal tube resistance type heater, followed by steel fin type heater, and the most expensive is ceramic type and alloy aluminum heater. However, due to structural problems, the efficiency of the alloy aluminum heater is the best due to its larger size and air contact area. Therefore, when choosing other forms of heaters in general, a larger heating capacity must be selected to compensate for the defects in efficiency.

    Equipped with a medium-effect over-rate heater

     The middle-effect EU4/5, first-class fireproof filter pistil, metal frame structure, can be extracted from the front of the unit without worrying about dust spreading into the room, and can be cleaned repeatedly and used for many times. At the same time, according to the actual needs of users, we can provide higher efficiency filters, which can reach EU8.

  • Advantages

     

  • 1, High reliability, high energy saving rate, high adaptability, low cost for whole life

    2, 100% full frontal maintenance, save space in the machine room

    3, Copeland high-efficiency scroll compressor, suitable for environmental protection refrigerant
