RVS Buffertank PWT-300
RVS Buffertank PWT-300: Stainless Steel Buffer Tank for Heat Pumps
The RVS Buffertank PWT-300 is a stainless steel buffer tank for heat pump systems, central heating installations and professional HVAC applications. It increases system volume, helps reduce cycling and supports more stable hydraulic operation.
Stainless Steel Construction and Reliable Thermal Storage
The tank is manufactured from Duplex 2205 stainless steel and designed for long-term use in technical installations. The combination of stainless steel, PU insulation and practical connection options makes this model a durable buffer solution for installers.
Energy Efficiency Class A and PU Insulation
With Energy Efficiency Class A, the high-quality PU insulation helps reduce heat loss, keeps stored heat at temperature for longer and supports lower energy consumption in heat pump and heating systems. This makes the Nexus stainless steel buffer range an efficient choice for reliable thermal storage, buffer volume and long-term energy savings.
Hydraulic Stability for Heating Systems
By adding buffer volume, the heating system can operate more smoothly. This supports stable flow, less frequent start-stop operation of the heat source and reliable long-term system performance.
