SOLAR THERMAL COLLECTORS

Flat panel solar collectors are manufactured according to European standards and are suitable for all applications (solar water heaters and forced circulation tanks).

They can be installed easily and quickly in both a vertical and horizontal position in any type of roof.

The flat collector H98 has an undivided selective coating (Full Face) and all the welding
are completed by an automated laser line. It has been designed with a high thermal
capacity and low pressure drop. In this way its efficiency is increased.

The collector’s insulation cover is constructed by an undivided anodized aluminum
section specially designed to be attuned with the rest of the parts by giving solidity and
contributing to the preservation of its efficiency.

It has a peripheral water flume in order to maximize the sealing and an extra flume to
avoid humidity.

There is a safety glass panel with low iron content (Low Iron) and high permeability
(Clearlight) that increases the amount of solar radiation on the collector’s coating and
as a result its efficiency.

In conclusion, the collector has a double polyurethane-stone wool (hybrid) insulation,
50mm thick on the surface of the cover and 25mm on its sides. In this way, it achieves
maximum thermal insulation (thanks to polyurethane) and protection of the insulation
against overheating (thanks to the stone wool).

The insulation is also protected by two aluminum panels that are installed on different
levels on the cover. In this way, the insulation abilities are preserved at the same level
for ever.

H98 COLLECTOR TECHNICAL SPECIFICATION

The flat collectors H80 have the Strip and Full face selective coating respectively.

The cover of the collector is constructed by a special undivided pre-painted (UV protected
color) metal sheet, which has a test certificate for endurance in near-coastal areas.

It is specially designed to be attuned with the rest of the parts by giving solidity and
contributing to the preservation of its efficiency.

There is a safety glass panel with low iron content (Low Iron). The H80 has a Mistlight
glass panel.

In conclusion, the collectors have a powerful stone wool insulation designed not to create
sprays at high temperatures. These sprays form a scale on the glass panel and decrease
its permeability.

The flat collectors H81 have the Strip and Full face selective coating respectively.

The cover of the collector is constructed by a special undivided pre-painted (UV protected
color) metal sheet, which has a test certificate for endurance in near-coastal areas.

It is specially designed to be attuned with the rest of the parts by giving solidity and
contributing to the preservation of its efficiency.

There is a safety glass panel with low iron content (Low Iron). The H81 has a high permeability Clearlight glass panel that increases the amount of solar radiation on the collector’s coating and as a result its efficiency.

In conclusion, the collectors have a powerful stone wool insulation designed not to create
sprays at high temperatures. These sprays form a scale on the glass panel and decrease
its permeability.
