Volano CUBE - Wall-Mounted Buffer Tank with Hydraulic Separator

Cordivari’s Volano CUBE is a compact, wall-mounted buffer tank with an integrated hydraulic separator, engineered specifically for modern heat pump and hydronic heating/cooling systems. By combining a buffer tank and separator in one unit, it simplifies piping, reduces short cycling, and helps stabilize system temperatures—all while hanging neatly on the wall beneath, or next to, your boiler or heat pump. Volano CUBE is available in 50 L (≈ 13 gal) and 80 L (≈ 21 gal) models, in either mild steel (GBL) or stainless steel (XBL), so you can match volume and material to the size and demands of each project. Why installers choose Volano CUBE Wall-hung design – Mounts directly on the wall to free up floor space and create clean, organized mechanical rooms. Ideal under wall-hung boilers and heat pumps. Built-in hydraulic separator – Internally separates generator and distribution circuits so heat pump and terminal flow rates are decoupled, protecting pumps and simplifying balancing. Patented
