TECHNICAL INFORMATION / INSTALLATION INSTRUCTIONS
Compact Solar Drainback System SECUSOL
Figure 1 SECUSOL-System
Operational Safety and Low Maintenance
When the pump is not operating, there is no solar fluid
present in the collectors. Therefore the solar fluid and any
downstream system components are protected against
detrimental effects from overheat. Unwanted gravitational
forces as well as operational faults due to air pockets are
eliminated. A service intensive membrane expansion ves-
sel, air bleeds and check valves are not required. Operati-
on with common anti-freeze solar fluid prevents potential
frost damage.
High Yield Thanks To:
● High transparency anti reflection glass
● Single surface absorber with selective vacuum coating
● Solid insulation of individual components
Simplified Installation and Start-Up
● Pre-assembled unit of storage tank, solar controller and
solar circulator, including all safety components.
● Flexible copper double-pipe with only 12mm cross
section, for simple and time saving piping (supplied by
Wagner & Co).
● No expansion vessel and hence no setting of pre-pres-
sure required.
● Very simple flushing and filling
● No venting of solar circuit required
Installation, startup and maintenance of the SECUSOL
solar thermal installation are intended to be carried out
by trained professionals only, e.g. in line with SRCC Stan-
dard OG-300 installation guidelines or NABCEP certifica-
tion. They have to be licensed, must be familiar with the
IAPMO Uniform Solar Energy Code and must conform
to applicable federal, state and local regulations, codes,
standards and meet all legal requirements related to the
installation of solar hot water systems as well as plumbing,
electrical wiring and roof works.
