SunEarth SolarStation FlowBox Pump Group with Pump & Line Cord
The SunEarth SolarStation FlowBox (SRS-FLOWBOX) is a factory-assembled closed-loop solar pump station designed for residential glycol solar domestic hot water systems. Built to simplify installation while providing reliable long-term performance, the FlowBox contains the primary hydraulic components required to circulate heat transfer fluid between the solar collectors and storage tank in an indirect solar thermal system.
The unit is supplied with a Grundfos UPS15-58U three-speed circulator pump, integrated fill and purge valves, balancing valve, flow meter, pressure gauge, thermometers, pressure relief valve, manual air separator, and factory-installed line cord for quick electrical connection. The compact expanded polypropylene insulated enclosure provides excellent thermal insulation while allowing convenient access for servicing and monitoring system performance.
Designed specifically for SunEarth SolarStation systems, the FlowBox significantly reduces field assembly time while providing installers with a clean, professional, and factory-tested solar pumping solution.
