[MultiW5 full-size]
Sub-category · Variable Refrigerant Flow
VRF systems for commercial, hospitality and residential.
Goldline's MultiW5 VRF range supports up to 32 indoor units per outdoor system, with T3 high-ambient variants engineered for sustained operation up to 50 °C — making it suitable for hotel, healthcare and residential tower projects across the Gulf and Sub-Saharan markets.
Variable Refrigerant Flow (VRF) systems modulate refrigerant flow to multiple indoor units from a single outdoor condensing unit, allowing zoned cooling and heating control with significant efficiency advantages over conventional split or chiller-based systems. Goldline's MultiW5 platform serves mid-rise hospitality, healthcare, mixed-use developments and commercial office fit-outs where zoning, energy management and acoustic performance matter.
For Middle East and African markets, the MultiW5 T3 variant is engineered with enhanced condenser surface area, optimized compressor selection and refrigerant charge tuned for sustained ambient temperatures up to 50 °C — published IEER figures are available on request through authorized distributor channels.
