VRF / VRV Systems
Advanced Multi-Zone Climate Control for Large Buildings
System Overview
Variable Refrigerant Flow (VRF) systems represent the pinnacle of HVAC technology, offering simultaneous heating and cooling to different zones within the same building. These advanced systems feature DC twin-rotary compressors, heat recovery technology, and industry-leading piping flexibility (up to 1000 meters total length). With capacities from 8 HP to 60 HP in a single system and up to 64 indoor units per system, VRF is the ideal solution for large commercial buildings, hotels, hospitals, and mixed-use developments. The SMMS series incorporates 7 key smart technologies for optimal performance.
