The ZP2-12 ECO pump station is designed for small solar thermal installations with a nominal collector surface area of up to 12 m2 (e.g., 5 KS2100F TLP AC collectors). The high-efficiency circulating pump used in the pump station allows the stringent requirements of the ErP directive for maximum electricity consumption to be met. The design of the two-way station allows the use of measuring elements – supply and return thermometers – directly. A pressure gauge, a float flow meter with control valve and a deaerator are also incorporated.
The latest generation of electronically speed-controlled circulation pumps have several times lower electricity consumption than older pumps operating at constant speed. The ZP2-12 ECO pump station includes a circulating pump whose operation can be controlled in accordance with the latest control standards (iPWM, iPWM2 signal). This allows the use of advanced algorithms to manage the operation of solar thermal systems, based on constant measurements of temperature and flow in the operating circuit. The energy efficiency of the entire solar thermal system is the highest of all heat sources. For every 100 W of heat generated, 1-2 W of electricity is usually sufficient.
The versatility of the ZP2-12 ECO pump station lies in the free choice of the solar thermal system controller. For users who prefer maximum operating functionality and, at the same time, for most typical small solar thermal installations, the plug-and-play MiniSOL controller is recommended. When expecting an extended range of functions and working with more accessories in a solar thermal installation, the GH26 model will be the recommended controller.
