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.
