LASERABSORBERS

The solar absorber is the most impor tant component of a solar collector

Our manufacturers with long experience in manufacturing solar absorbers and

collectors, offers now the new Laser Full plate Absorber bonded by laser

welding to copper header-riser tubing.

The excellent selective material we use is MIRO- THERM, a selectively blue

coated aluminium substrate. After extensive stagnation tests we are confident

to avouch durability of our product at highest thermal stress.

Also accelerated corrosion tests in brine solution have shown life expectancy

rates above 20 years.

The AdvantagesOur new method of laser welding the pipe to the plate gives several advantages:

the rear side.

Laser welding is done at low temperatures, which reduces the tension of

material between plate and pipe.

The absorber’s coated surface remains intact and free from mar s, that ma es

it suitable for clear glass collectors.

The absorber can resist to high temperature stagnation and high corrosion

levels.

Our laser welding process is environmentally friendly because it needs no

additives and does not release any harmful substances into the environment.

A protection foil prevents damage to the selective surface coating until the

absorber is assembled with the collector.

Due to a 0.5mm absorber sheet, handling is much easier than with

copper absorbers.

technique, which provides excellent thermal contact between pipe and

The cost of coated aluminium sheet is lower than comparable selectively

coated copper products.

MIRO-THERM coating was developed by ALANOD, a company

A multi layer selective coating is deposited on aluminium substrate by PVD technique.

Three optically active layers are applied by a special «Air-to-Air» thin film process.

A PVD anti corrosion layer protects the aluminium sheet on the rear side.

Solar absorbtion (AM1.5) · = 0.94 ± 0.02

Thermal emission (100 ˚C) Â = 0.05 ± 0.02

Laser ProcessOur pulsed laser welds the tubes and the metal sheet together in very small spots on the rear side of the absorber, in order to prevent any

damage to the front side.

Powered by 3 laser welding machines on fully automatic CNC machines, we can offer both strips and full plate absorbers, in widths up to

2000mm and length up to 6000mm. Every absorber is tested at 16bars pressure.

We first check that the height of the pitch roof from the

highest top until the lower part of the solar system is at

least 3800mm-minimum.

We begin from the lower part of the support base by

raising the tiles and positioning the stainless steel straps (F)

between and under the convex of tiles with a distance

between them of a min. 900mm and max. 1080mm

(D1-D2).

We screw the stainless steel straps to the oblong wood or

flooring as at (photo 1) and we leave the one side out of the

tiles, at least 200mm in the same distance and length

between them.

We reposition again the tiles as they were and we screw the

external side of the stainless steel straps (F) on the vertical

long bracket supports (A-A) of the support base (photo 2)

with the plastic hatch on the

installed at the lower side of the collector(s) and the other

edge at the filler neck of the bottle, as long as we have already

lifted the bottle and the plastic tube (L) at the same height

with the water tank (photo 4). Then we start filling up the

closed circuit (loop) with the thermal fluid of the bottle and

when it will be finished we continue filling it up with water

until the water tank will run over from the tube at the side

(N-08), which means that all of the air has come out, the

closed circuit is filled up and we can screw the security valve

finally. At the end, as long as we have checked very

carefully all of the connections for any possible leakages, we

position the protection side cover of aluminium (J) as at
