Filling solar collectors with glycol in a fast and efficient way is an easy job with the ZUWA Solarcheck Mobilcenter, now available in a compact version. The reliable, easy-to-maintain ZUWA impeller pump has a flow rate of 8 gpm and a maximum pressure of 75 psi. Air bubbles are flushed out as well as sediments or other residues. The station can be used with fluid temperatures up to 195 degrees F. The time required for the filling process is reduced by 30 to 40 percent. www.zuwa.de.
