The Solar X-Pump Block combines a stainless steel flat plate heat exchanger with two bronze circulators and a solar differential temperature control in one compact package, ideally suited for installations where adding a solar storage tank is not feasible or where the solar storage tank does not have an internal heat exchanger.
The Variable Speed Solar Pump line includes circulators with integral solar differential temperature controls. All wiring for power and sensors is done directly to the circulator, while the LED status pane makes it easy to check functionality. Dip switch settings offer easy set-up. Pumps continually adjust speed to reduce short-cycling, maximizing solar collector output and system efficiency by up to 20%.
