The BT-50 WM-B-C2 Black is a compact 50 L stainless steel buffer tank for heat pump and heating systems.
The BT-50 WM-B-C2 Black is a compact 50 L stainless steel buffer tank for heat pump and heating systems. It increases system volume, improves hydraulic stability and helps reduce unnecessary cycling of the heat source in compact installations.
The Nexus BT-50 WM-B-C2 Black increases system volume and helps improve hydraulic stability in heat pump and central heating installations. This supports smoother heat source operation and helps reduce unnecessary cycling.
This buffer tank is designed for installers who need a compact and durable storage solution with top connections, double internal and external thread connections, and a clean professional finish.
The inner tank is made from Duplex 2205 stainless steel for high corrosion resistance and long service life. The black frosted-metal outer casing gives the buffer tank a modern appearance in technical rooms and HVAC installations.
