SolexMega-Kaskade HZ DN50
For charging buffer storage tanks up to 400 m² of collector surface
Solar pump: prim.: Grundfos UPM XL 25-125, sec.: Grundfos UPML 25-105
The compact and completely premounted transfer station is completely insulated. The transfer station is equipped with two generously dimensioned stainless steel plate heat exchangers and with a preset and prewired controller

All connections 1½" internal thread
Floor-standing station, premounted in steel rack, simple and quick installation
All fluid-carrying parts made of brass or stainless steel, fully assembled - self-sealing or flat-sealing
Full port ball valves primary and secondary, with large levers for easy handling, visible closing position
Check valve in the solar and secondary circuit, can be opened, 200 mm wc, especially for solar systems, prevents gravity circulation
Airstop in the flow line for permanent deaeration of the heat transfer medium

With high-efficiency pumps by Grundfos - already installed and prewired; adapted to the performance of the transfer station, pumps can be isolated completely, no draining necessary during pump service

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 expansion tank, secondary side with 6 bars pressure relief valve

Compact design insulation with optimised function made of durable elastic EPP, 100 % insulated valves and fittings, minimal heat losses

High-efficiency plate heat exchanger
