The compact and completely premounted transfer station consists of two modules connected by a pipe set.Modules and pipe set are completely insulated.Each module is equipped with generously dimensioned stainless steel plate heat exchangers.The preset and prewired controller allows a simple and quick installation as well as a safe commissioning.

All connections: 2" external thread
two screwed flanges from 2" internal thread to DN 50/PN 6 enclosed

Floor-standing station, premounted in steel rack,
simple and quick installation and connection

Full port ball valves on primary side, with large levers for easy handling, visible closing position
full port piston valves on secondary side

Check valves at the primary flow and return ball valve, can be opened, 200 mm wc, especially for solar systems, prevent unwanted circulation

Solar circuit with large ball valve handles
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, piston valves in the secondary circuit

Airstop in the flow line for permanent deaeration of the solar fluid and for controlled venting of the installation

With high-efficiency pumps by Grundfos (PWM for speed control), premounted and prewired, adapted to the performance of the transfer station, pumps can be isolated completely, no draining during servicing

FlowRotor, flow meter on primary side for speed control of the secondary pump, depending on the performance and heat quantity balancing (primary)

Flush and fill unit integrated two fill and drain valves in the flow and return permit filling and flushing the primary circuit

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, 10 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
