VLS

Advanced air-water chillers and heat pumps featuring low-GWP refrigerant R454B with exceptional seasonal efficiency for reliable year-round performance.

The VLS range represents Galletti's commitment to maximum seasonal efficiency and reliability across all operating conditions. These units deliver high seasonal efficiency—SCOP up to 4.04 and SEER up to 4.69—while maintaining excellent partial-load performance through innovative component design and intelligent management systems.

Built with cutting-edge technology, VLS units feature modular construction with a compact footprint and significantly reduced refrigerant charge. The range includes 13 models available in cooling-only or reversible heat pump configurations, with options for both standard and low-noise acoustic setups.
