High Performance Design
Vacuum tube collectors achieve
excellent results, not just year-round, but
particularly in cold and windy conditions.
The collectors’ absorbers are located
inside vacuum tubes, which, much like
a thermos, have excellent insulating
qualities and prevent heat loss. Solar
energy is captured by a selective surface
coated copper absorber sheet inside
the evacuated glass tubes. With highly
effi cient heat pipe vacuum tubes such as
those on the Vitosol 200-T, the captured
heat evaporates water inside a heat pipe,
which then rises to a condenser. Fully
encapsulated condensers inside a cast
aluminum block (SPE) or integrated within
a Duotec double pipe stainless steel heat
exchanger (SP2A) transfer the heat to
the circulating solar fl uid. Combined with
highly-effective thermal insulation in the
header casing, these designs ensure
extremely effi cient heat transfer and
minimize additional heat loss.
Easy Installation
Roof mounted systems with rafter
brackets, angled frames or wall mounting
brackets simplify installation, saving
both time and money. Flexible pipes
with O-rings enable quick connections,
and a connection set with compression
fi ttings enables the collector array to be
readily connected to the pipes of the solar
circuit. A temperature sensor is fi tted
into a sensor well built into the collector
header. New retaining caps prevent the
tubes from slipping off during installation
and maintenance; if service is required,
“dry connections” allow individual tubes
to be replaced quickly and easily without
draining the system.
Flexible Mounting Options
From residential homes to large
commercial and industrial systems,
the Vitosol 200-T provides numerous
installation possibilities.
The Vitosol 200-T can be installed on
sloped or fl at roofs, horizontally (laying
fl at) or freestanding. On sloped roofs,
collectors may be positioned vertically
(tubes at right angles to roof ridge) or
horizontally (tubes parallel to roof ridge).
The Vitosol 200-T, SP2A adds a horizontal
wall mounting option and is available in a
10-tube model designed for installation on
balcony railings or walls.
The Vitosol 200-T, SP2A is available in 10,
12 and 24-tube models, while the Vitosol
200-T, SPE is offered in 9 and 18-tube
versions. In commercial applications, up
to 96 tubes of the Vitosol 200-T, SP2A or
108 tubes of the Vitosol 200-T, SPE can
be easily connected in a single array with
quick-connect fi ttings and easy-to-use,
pre-engineered mounting systems.

Highly effi cient heat pipe
vacuum tube design
In a heat pipe vacuum tube,
heat captured by the absorber
evaporates the water in the
heat pipe, which rises to the
condenser. Heat is transferred
to the solar fl uid circulating
through the header, where it
condenses.
