The VRV IV S-series system is a highly efficient solution for small commercial buildings requiring heating and cooling of up to 10 zones. A mix of ducted and duct-free indoor units can be combined to provide individual comfort and ease of installation. With its simple, versatile design and long piping (up to 230 ft. actual piping length one way), the VRV IV S-series can accommodate practically any floor layout, enabling better use of space.
Its advanced zoning capabilities allow floor-by-floor installation so that each floor can be occupied quickly upon completion. And, because the outdoor units are lightweight and vibration-free, there's no need to reinforce floors, reducing both installation time and costs.

• Space-saving design to fit in tight areas and realize quick and easy installation.
• Savings in energy use due to higher SEER and HSPF ratings when compared to VRV III-S.
