Product Information

Product Description

Benefits
■ Highly efficient vacuum tube collector based on the
heat pipe principle for high operational reliability.
■ Can be universally installed anywhere, either vertically
or horizontally, on roofs, as well as for horizontal
freestanding installation on flat roofs, as well as walls.
■ Special balcony module (1.26 m
installation on balcony railings or walls.
■ The absorber areas with a highly selective coating
are integrated into the vacuum tubes and therefore
are not susceptible to contamination.
■ Efficient heat transfer through fully encapsulated
condensers, with the Duotec double pipe stainless
steel heat exchanger.
■ Tubes can be rotated (up to 25°) for optimum alignment
with the sun, thereby maximizing the energy utilization.
■ Dry connection, meaning tubes can be fitted or replaced
when the system is fully operational.
■ Highly effective thermal insulation for minimized heat
losses from the header casing.
■ Easy installation through the Viessmann assembly and
connection systems.

Vitosol 200-T, SP2A Technical Data
The Vitosol 200-T, type SP2A can be installed on
sloped or flat roofs as well as horizontally (laying flat)
or freestanding as well as on walls. On sloped roofs the
collectors may be positioned vertically (tubes at right
angles to the roof ridge) or horizontally (tubes parallel to
the roof ridge).
A highly selectively coated metal absorber is incorporated
inside each vacuum tube. It ensures high absorption of
insolation and low emissions of thermal radiation.
A heat pipe filled with an evaporation liquid is arranged
on the absorber. The heat pipe is connected to the
condenser. The condenser is located inside the Duotec
double pipe heat exchanger made of stainless steel.
The system is referred to as a "dry connection",
i.e. tubes can be rotated and replaced even when the
system is filled and is pressurised. The heat is transferred
from the absorber to the heat pipe. This causes the liquid
to evaporate. The vapor rises into the condenser. Heat is
transferred by the heat exchanger with its copper
manifold, inside which lies the condenser, to the
heat transfer medium streaming past, and the vapor
condenses. The condensate returns back down into
the heat pipe and the process repeats.
The angle of inclination must be greater than zero to
guarantee circulation of the evaporator liquid in the
heat exchanger. Deviations from south can be partially
compensated for by rotating the vacuum tubes up to 25°.

Up to 161 ft (15 m ) absorber area can be connected
to form one collector array. For this purpose, the standard
delivery includes flexible connection pipes with O-rings.
The connection pipes are insulated and concealed with
an aluminum cover.
A connection set with clamping ring fittings enables the
collector array to be readily connected to the pipes of the
solar circuit. The collector temperature sensor is fitted
into a sensor well inside the collector header casing.
