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.

All connections ¾" internal 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
