RVS Buffertank BT-400L: Stainless Steel Buffer Tank for Heat Pumps
The RVS Buffertank BT-400L 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 stainless steel AISI 304 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.
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.
Key Features
- Manufactured from stainless steel AISI 304
- High-quality PU insulation to help reduce heat loss
- Designed for installers, resellers and HVAC professionals
- Increases system volume and improves hydraulic stability
- Suitable for heat pump and heating systems
