With Lennox powered by Samsung, you can unlock the full potential of VRF—combining proven, innovative products with the direct speed, service and support of Lennox.
How It Works
Varix systems combine advanced engineering with intelligent controls that learn from your building's needs, continuously optimizing performance and efficiency. By regulating variable refrigerant flow (VRF) rates between source and indoor units to match real-time demands, a single source unit provides independent temperature control across multiple zones.
FOUNDATIONAL COMPONENTS
Seamlessly Deliver Zoned Comfort from a Single Source
The heart of every Varix™ VRF System is its advanced condensing unit, either a low-ambient outdoor unit (shown here) or water source.
Varix outdoor units have a small footprint, easing installation where space is limited.
Refrigerant lines distribute heating and cooling to zones, maximizing usable space versus traditional ductwork.
Advanced Control, Exceptional Efficiency
Deliver efficient, personalized comfort by intelligently managing heating and cooling where and when needed.
Reduce operating costs through precise zone control, smart load matching and advanced energy recovery
Maintain peak efficiency with AI-driven performance optimization that learns from your building's needs
Achieve proven cold-climate and hot-climate performance, from -22°F to 122°F
Eliminate cold drafts with proprietary cooling technology that disperses gentle “still air”
Meet tomorrow’s needs with future-ready systems equipped to meet low-GWP refrigerant, electrification and decarbonization mandates
Turn Wasted Energy into Comfort
Varix systems capture heat from cooling zones and redirect it where heat is needed, delivering efficiency and comfort simultaneously.
