The X3 series now incorporates an advanced G-type heat exchanger, which significantly enhances the heat exchange area and efficiency. Moreover, the manifold system is equipped with a 3000-step electronic expansion valve, enabling superior partition control, improved distribution of refrigerant load, and enhanced overall heat exchange performance.

Hisense VRF uses refrigerant cooling technology to cool the elec-trical control box. It overcomes the poor heat dissipation and high ambient temperature issues to maintain efficient opera-tion even at harsh environment. Compared with air-cooled tech-nology, the temperature inside the electrical box can be reduced by up to 20%*.

Moreover, the refrigerant cooling kit adds a tem-perature sensor, which could be more precise to control the refrigerant cooling temperature and ensure the whole reliability.

If one module in a combination system malfunctions, the other ones can still keep working to ensure an emergency operation until service and repair.

In the single module system equipped with two compressors, if one compressor malfunctions, the other one can provide emergency operation. In the combined modules, if the compressor in one module goes wrong, the other modules can provide emergency operation. Thus a stable and continuous operation can be ensured thanks to the backup of compressors.

For the module equipped with two fans, if one breaks down, the other one won't be influenced, the module can still keep working.

Hi-FLEXi X3 series unit is featured with automatic refrigerant charging function, a first-time feature for Hisense products. Compared with manual refrigerant charging, automatic refrigerant charging can greatly simplify the process, and improve the efficiency of the installation and commissioning.

Hisense VRF has one-touch refrigerant recycle function. Just with a press of the button on the PCB, the refrigerant can be recycled directly. It is very helpful and convenient when the indoor units or the compressor are under repair.
