The technical data above has been verified and confirmed by tests conducted by the South African Bureau of
Standards in terms of SANS 6211, at an incoming radiation of 20MJ per m² per day, a temperature differential
of10°C at an inclination of latitude plus 10°.
2.3 Orientation and placement
North-facing (true North) is optimal when installing in the southern hemisphere, however deviations of up to 45°
either side of North would be acceptable with very little effect on system performance,
SunScan
does not
recommend the installation exceed the 45° range either side of North, however some exceptions may be made
when 45° off North cannot be achieved. Contact a
SunScan
Representative for a rational design.
The collector should be mounted in an all year round shade-free area, or an area that does not shade between
the hours of 9:00am
– 15:00pm.
Take care to ensure the roof area chosen for installation is structurally sound and capable of bearing additional
weight. Consult a trained professional if required, if the roof or structure is found unfit to carry additional load, do
not install the system unless the roof can be sufficiently strengthened.
2.4 Freeze protection
The
SunScan SunStream
indirect system is suitable for areas that experience frost and temperatures
below 0°C as the heat transfer fluid has anti-freeze properties.
2.5 Hail resistance
SunScan
flat plate collectors are hail resistant with 3mm tempered glass, they can withstand hailstones of up
to 35mm in diameter.
2.6 Scale resistance
The
SunScan SunStream
150L indirect system is suitable for areas with
‘poor water quality’ as the
collector and internals of the heat exchanger transport a scale resistant heat transfer fluid, however care should
always be taken to ensure that scale and mineral deposits do not affect the longevity of your SunScan indirect
system, if you are unsure as to the water quality in your area consult your local municipality.
Generally, water quality is acceptable when it contains less than 600 parts per million total dissolved solids.
