Product Overview
The RVX 130 hot water central storage module serves as the core integration point for modular renewable energy heating systems. Two storage tank options accommodate different applications: 100L buffer tank with single heat exchanger for simple storage circuits, or 200L bivalent tank with dual heat exchangers for complex multi-source systems. Circulating pump delivers up to 3.1 m³/h flow at 5m maximum head with variable speed control. Driven 3-way valve directs flow to different circuits based on control logic. Temperature sensors monitor buffer and room conditions. Two pressure sensors provide system safety monitoring. Flow meters quantify heat transfer rates. Quick-release couplings on front panel enable rapid hydraulic connection to solar thermal, heat pump, and fan heater modules. Pressure relief and bleed valves ensure safe operation. All components operate at maximum 96°C temperature and 5 bar pressure. Optional LABVIEW DAQ software transmits temperature, pressure, and flow data to external controller for real-time system analysis.
