Solar hygienic layered accumulator
SP 500 – 2,000 SW 1 + 2
The details of this solar hygienic layered accumulator’s design are tailored perfectly to Hargassner control and hydraulic systems.
Besides an integrated return spread sheet and variable sensor positioning, this accumulator convinces through a highly efficient solar heat exchanger. It is available with a bottom solar heat exchanger or solar heat exchangers at the top and bottom.
- SW 1 – heat exchanger at the bottom
- SW 2 – heat exchanger at the top
With the bottom-positioned smooth pipe heat exchanger, a perfect solar integration is possible. In the twin solar heat exchanger version, the top heat exchanger is used to heat the top layer of the accumulator tank quickly. The lower heat exchanger is for complete loading of the accumulator tank and for pre-heating of the water at low solar heat generation.
