Vitosol 200-T
VITOSOL 200-T
The Vitosol 200-T vacuum tube collector is based on the heat pipe principle, delivering
additional benefits, in common with the 300-T.
In the 200-T there are a number of additional
installation benefits, as the tubes can be
fitted onto flat roofs without the need for an A
frame, and they are also suitable for horizontal
or vertical installation onto walls.
Heat pipe collectors are best applied
when the system is expected to be used
intermittently or when the heating capacity
will often be greater than the heating
requirement, as this presents a high risk
of stagnation.

Highly efficient vacuum tube collector
based on the heat pipe principle for high
operational reliability against overheating
The Sol-titanium coated absorber surfaces,
which are integrated into the vacuum tube,
are not susceptible to contamination
Tubes can be rotated for optimum
alignment with the sun, thereby
maximising the energy yield
Highly effective thermal insulation of
the header casing for minimal thermal
losses, enabling conversion of even low
levels of solar radiation
