PLUS DTH

The solar collectors from the 10 DTH-CPC series are the result of many years of work in the pursuit of excellence. We strive for customer satisfaction by ensuring quality, reliability and performance are always improving. For this purpose we have merged all its thermal engineering know-how into the 10 DTH-CPC solar collectors, as well as experience in the field and the ongoing confrontation with the international cutting edge of solar heat.The 10 DTH-CPC collector has been designed in a single size to ensure perfect modularity, and make the execution possible for both small household systems and large industrial systems.

THE PRODUCT

CERTIFICATES

There is a direct connection that links Concept Quality with Management and Production Quality. Production process has obtained ISO 9001:2008 certification for the design and manifacture of solar thermal collectors and systems, the DTH collectors have obtained EN 12975 certification for quality and performance as well as the SOLAR KEYMARK attesting to the consistency of quality in production.

EXCELLENCE OF VACUUM

The best technology at your disposalThe new generation of vacuum tubes and patented geometry of the parabolic reflector provide greater energy efficiency in all climatic condition of the year and not only in summer.The continuous research into vacuum technology applied to solar heat, has created collectors that combine the highest efficiencies (due to the tri-selective absorber positioned on the innermost tube), the maximum strength and durability (due to the use of special extra thick glass with high hail resistance).

BENEFITS

• High resistance to the most adverse weather conditions such as hail• The vacuum tubes and their performance are guaranteed over the years• The energy production taker advantage even of diffused light • The parabolic and cylindrical surfaces of the absorber increase the yield per total square metre of roof occupied• Rays of slanting light are also captured• With harsh outside temperatures efficiency is higher than the classic flat panels by up to 70%

MAXIMUM HEAT EXCHANGE EFFICIENCY

BENEFITS• The copper internal exchanger with concentric coaxial-flow of the DTH-CPC collectors has an area of exchange that is 40% higher

than the standard U-pipe collector• The large passage sections eliminate any possibility of clogging of the circuits and minimize load losses to the benefit of the electrici-

ty consuption of the solar pump• The centre of the DTH-CPC solar collector consists of a single heat exchanger welded and tested with a high resistance to pressure,

without joints and fittings. • The testing is carried out with the most innovative techniques on 100% of the products• Maximum resistance to thermal expansion and to shocks to ensure a long life of the exchanger• The coaxial flow geometry allows the collector to produce heat even when installed horizontally or vertically on a surface.

ACCURATE PRODUCTION

The DTH collector exchangers are products Made in Italy with the most advanced technologies for the automatic processing of copper.This guarantees product quality, the consistency of the geometry and the longevity of the solar collector.

On the balcony, on the roof, on the façade

BENEFITS

• The new alluminium frame with 4 is made from cold pressing and increases tortional stiffness by 30% compared with standard frames• The interior and lower lateral cavities of the frame allow any type of coupling and fastening even customized • The packaging is made entirely out of thick contoured cardboard ensuring maximum protection during transportation• The fitting accessories allow quick and safe installation in all possible situations: flat roof, sloping roof with tiles, slate or corrugated

steel, horizontally on the balcony (well integrated on existing architecture) on the vertical façade (greater performance in winter and less hot water in summer)

Quick and modular installationDesigning a good product also means knowing and foreseeing all of its installed applications, simplifying handling, the management of packaging, installation without time losses, fixing and connecting plumbing. All must be done with:• certainty• safety• speed• reliability over timeFor this purpose DTH project aimed to create a product that is easy to install.

EASY INSTALLATION

EXCELLENT PERFORMANCE

Stable efficiency even in the cold The excellent thermal insulation and the innovative design of the reflective elements guarantees excellent efficiency of the DTH-CPC solar collectors even with very harsh outside temperature.

Peak Power Curve

Energy at any time of dayAs shown by the results of testing, the DTH-CPC collectors are able to capture the brightness present and oblique radiation excellently because the cylindrical surfaces of the tube and the paraboloids of mirrors amplify the useful surface area.
