The Cirtek project is a semiconductor factory lying in Philippines and it is also the first local V5X series VRF project after forming JV Company in Philippines. The factory provides chips and other hardware for worldwide communication equipment companies. For the present time, there are 4 phases of construction with the estimated capacity of 4,500 HP and the first phase is about 1,176 HP. In order to provide the suitable solution for the project, MBT applied the fresh air treatment design and also took advantage of the biggest 88 HP combination capacity of V5X. Besides, owing to high COP & IPLV and cool appearance of V5X compared with our competitors, we successfully won the first phase of the project at the end of 2015. MBT also provided professional installation and commissioning guidance in order to guarantee normal operation.
