The compact and completely premounted solar transfer station is completely insulated and equipped with a generously dimensioned stainless steel plate heat exchanger and with a preset and prewired controller.For a simple and quick installation as well as a safe commissioning.
Primary connections ¾" internal thread, secondary connections: 1" external thread
Premounted on steel wall bracket
can be easily mounted to the wall
All fluid-carrying parts made of brass or stainless steel, fully assembled - self-sealing or flat gaskets
Solar circuit with ball valves
key-actuated, easy handling, visible closing position, with integrated full metal thermometer 0-160 °C, can be pulled off, with immersion sleeve integrated in the ball valve, secondary circuit with piston valves
Check valve in the solar and secondary circuit, can be opened, 200 mm wc, especially for solar systems, prevent unwanted circulation
Airstop in the flow line
for permanent deaeration of the solar fluid
With high-efficiency pumps by Grundfos, premounted and prewired, adapted to the performance of the transfer station, pumps can be isolated completely, no draining during servicing
Flush and fill unit integrated two fill and drain valves permit filling and flushing the primary circuit, secondary circuit with pressure relief valve at the highest point of the heat exchanger
FlowRotor, flow meter for speed control of the secondary pump, depending on the performance and heat quantity balancing (secondary)
Solar safety group
Solar pressure relief valve 6 bars, pressure gauge resistant to high temperatures 0-6 bars with valve, flat sealing connection for a diaphragm expansion tank, secondary side with pressure relief valve, 6 bars
Compact design insulation with optimised function
made of durable elastic EPP, 100 % insulated valves and fittings - excellent ventilation and cooling of the pumps, minimal heat losses
High-efficiency plate heat exchanger
generously dimensioned, for transmitting high performances with low temperature differences, completely integrated into the insulation
