To maintain the lifespan of the delicate electronics, Hi-FLEXi S mavo series cooling only unit uses a patented 360 degree fitted refrigerant cooling technology, to effectively cool the whole electronic box. It overcomes poor heat dissipation and solves high ambient temperature issues inside the electronic box, to maintain an efficient and reliable operation under harsh environment. What's more, the refrigerant cooling unit adds a temperature sensor, which could be more precise to control the refrigerant cooling temperature and enhance the whole reliability.
