Product Description

Vitosol 200-T, SPE Technical Data

Benefits

■ Highly efficient vacuum tube collector based on the
heat pipe principle for high operational reliability.
Optimized for horizontal installation on flat roofs.

■ Optimized tube spacing prevents shading.

■ Can be universally installed anywhere, either vertically

or horizontally, on roofs as well as for horizontal and
freestanding installation.

■ 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.

■ Tubes can be rotated (up to 45°) for optimum
alignment with the sun, thereby maximizing the energy
utilisation.

■ 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.

The Vitosol 200-T, type SPE can be installed on sloped
or flat roofs as well as horizontally (laying flat) or
freestanding. 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 a heat
exchanger designed as a block made from aluminium
and copper.

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 215 ft
to form one collector array. For this purpose, the standard
delivery includes flexible connection pipes with O-rings.
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.

Installation with roof brackets

■ This method of fixing can be applied universally on
all common roof covers.

■ The fixing system comprises roof brackets, mounting
rails, clamping brackets and screws.

■ Forces are applied to the roof structure in various ways,
including via the roof brackets and the roof cover. Roof
covers can be very different. Consequently, damage
cannot be completely excluded in the case of applied
loads.

Mounting bracket

Note: During installation, e.g. on sheet steel roofs,

the mounting rails are secured directly on to
the mounting brackets with T-bolts.
Use on-site fixing options to secure the brackets,
to the substructure.
