The Fan Heater Unit RVX 129 is an educational apparatus for studying fan convector heating and cooling applications in thermal systems. This fan heater unit functions as heat source for room heating or heat sink for heat pump systems with dual-speed axial fan and integrated temperature measurement.
Product Overview
The RVX 129 fan heater unit comprises fan convector, pipework, quick-release couplings with shut-off valves, and temperature sensors for dual-mode operation. Axial fan with two selectable speed settings from 0 to 1400 rpm delivers flow rates up to 1200 m³/hr. Heat exchanger provides 2kW cooling capacity at maximum 10 bar operating pressure. Dual temperature sensors on feed and return pipes measure thermal gradient. Three temperature sensors monitor system performance. Flow rate measurement ranges from 10 to 3000 L/h. Quick-release couplings enable rapid connection to modular heat pump and heating systems. The fan heater unit achieves efficient room heating at lower circuit temperatures compared to traditional radiators. As air heat exchanger in heat pump systems, it absorbs ambient air heat when groundwater or geothermal sources are unavailable. Optional LABVIEW DAQ software transmits temperature and flow data to external controllers for energy analysis.
