Solar collector KS2100 TP ACR

Flat plate solar collector KS2100 TP ACR distinguishes itself by maximum efficiency due to the use of anti-reflective glass. The laser welded absorber is made of high quality materials – aluminum and copper (Al-Cu). High efficiency is also achieved by application of selective absorber coating (PVD) and full thermal insulation of the casing.

Possible application

Flat plate solar collector KS2100 TP ACR is designed for small houses as well as large solar thermal systems. Perfect for single-family homes and apartment-houses, as well as commercial, industrial and other buildings. They can also be used for heating pool water and to support central heating. The recommended inclination from horizontal is between 30 do 45° for optimum year-round operation. Mounting kits allow installation of collectors on various roofings, directly on the roof slope, as well as on building`s wall, flat roof and on the ground.

Structurized, U1 transmittance class glass, allows high optical efficiency 80,2%, confirmed by the Solar Keymark certificate (SPF Rapperswil Institute). The 50mm thick thermal insulation made of rock wool, in combination with wall insulation of 20mm, provide low heat losses. In contrast to KS2100 TLP ACR the casing is not painted. Chosen composition of aluminum ensures protection from external conditions and corrosion.

Characteristics and application of the KS2100 TP ACR solar thermal collector

Aluminum copper absorbers are a common standard on the European solar thermal collectors market. Using an aluminum plate allows production of a lighter collector with lower production costs. At the same time quality and efficiency are kept at the same high level as in copper absorbers. Laser welding provides maximum durability and mechanical strength through joining aluminum plate and copper piping and excellent transmittion of heat to heating medium. Moreover, a laser welded absorber is characterized by high aesthetics.

The glass used in production of flat plate solar collector KS2100 TP ACR is characterized by high permeability to solar radiation (transmittance). Additional, double sided anti-reflective coating is applied to the glass. it transmits 96,7% of solar radiation which classifies it as highest, X1 category among anti-reflective glass. Therefore more solar radiation reaches the absorber. The glass has undergone standard resistance tests according to norm PN-EN 12975-2, which is confirmed by Solar Keymark certificate. The tests include, among others, load resistance (snow, wind, load during tests ~100kg/m2), impact resistance, suction power resistance (wind, ~100 kg/m2) and hail resistance (ice balls 25mm in diameter).

The casing of a flat solar thermal collector must protect it from adverse environment conditions, be inflexible, tight and resistant to corrosion. The KS2100 TP ACR collector`s casing is made of aluminum with increased thickness. Combining the border of the glass with bottom part of the casing is a durable solution in the full range of operation temperatures as well as resistant to humidity and UV radiation. The casing is not painted.

Flat plate collectors KS2100 TP ACR may be installed on a pitched roof as well as flat one, building`s wall and on the ground. Hewalex offers a selection of brackets and mounting kits. Harp arrangement of the absorber allows connecting KS2000 TP ACR collectors in various ways. They may therefore be put parallely, as well as in series and in parallel series on restricted roof area, etc. The collector does not need to be levelled, which also facilitates installation.

We offer masking profiles KSL for collectors installed in one battery, which improves the aesthetics. They hide the connectors and fill spaces between adjacent collectors.

Due to higher efficiency, solar collectors with anti reflective coating of the glass are a perfect fit for industrial application, where higher operation temperatures are required. TP/TLP ACR solar collectors are not a standard in ready-made, complete solar sets, however they can be individually chosen to create solar sets for small systems.

NOTICE: Complete solar sets include only full painted version of collectros ex. KS2100 TLP ACR. Solar collectors with non-painted casing, ex. KS2100 TP ACR, are available in our offer.

PVD coating (blue coating) is a market standard in high efficiency solar thermal collectors. Metallic and ceramic coatings develop in production processes of PVD (Physical Vapour Deposition). Selective PVD coating is characterized by highest work efficiency, due to absorbing of 95% of solar radiation and heat emission of no more than 5%.

The casing is thermally insulated – the bottom as well as the walls. Thickness of thermal insulation is suitable also for operation in cold environment. Thermal insulation is made or rock wool, with minimum quantity of tackifiers. Therefore the risk of pollution in higher temperatures in eliminated (protecion of absorber and inner surface of glass). Rock wool is a natural material, therefore it keeps its properties during whole life of solar collector.

Flat plate solar collector KS2100 TP ACR, according to PN-EN 12975-2 norm, has undergone tests for thermal shock and prolonged overheating. Stagnation temperature, 210 oC, proves high efficiency construction as well as resistance to overheating. Such high temperatures are maintained for a long time during testing to check if no damage appears of any of the collectors` components. Such protection is provided mainly by the piping configuration. Harp arrangement allows for fast, automatic removal of glycol from the absorber at the very start of stagnation. It protects glycol and solatr thermal installation from damage.

Single harp absorber is characterized by low flow resistance (even 20-30 times lower compared to single flow absorber). It allows larger distance between roof and boiler when installing the collectors. Moreover, circulation pump consumes less energy. Operation with higher flow rate decreases thermal loss and increases collector`s efficiency. Low flow resistance allows connection of collectors parallely and in series of 8 and 5 units (or larger chains upon request). 

KS2100 TP ACR solar thermal collectors are equipped with 3/4" pipe stubs. Seals made of fluor-caoutchouc VITON® Du Pont are resistant to mechanical and chemical load in temperatures ranging from -40 to +220 oC. Use of unions eliminates the risk of damage to sealing surfaces (as it is in regular pipe stubs with slide connector), which may result in need for exchanging the collector. Purchasing replacement seals of union connection as well as their installation, are easy and low cost operations for the user.

10 years warranty

Since the 1990s, Hewalex has been granting its` Customers the longest warranties on the market for solar thermal collectors. The standard warranty on KS2100 TP ACR collector is 10 years. Moreover, the warranty conditions are one of the best on the market in terms of duration and minimum operation restrictions.

Good technical solutions and precise construction

Collector`s constructional solutions as well as production technologies are based on over 25 years of experience – the longest on Polish market. In 2007 Hewalex was the first in Poland to introduce ultrasonic welding, which provides highest precision and quality of copper absorbers. Connection of absorber sheet with piping at a molecular level with no other additional binder is characterized by maximum mechanical strength and highest coefficient of heat transmittion. PVD coating`s characteristics are high absorption of solar radiation (95%) and minimum heat emission (5%)

Collector`s case is made of aluminum with increased thickness. It allows stability and corrosion resistance. In the production process, Hewalex uses as many components as possible from domestic manufacturers. The company`s collectors with Cu-Cu absorbers were the first ones in the country to receive a Solar Keymark Certificate in 2007.

Small and large solar thermal installations

In over 25 years of our history, we delivered solar thermal collectors to over 140 000 buildings and objects in Poland and abroad. Over 140.000 solar thermal installations are successfully operating in small buildings, such as single family homes, as well as in big apartment houses, hotels, office buildings, medical institutions and industrial buildings. For the best whole year operations, the advised inclination of collectors is 30 to 60°. In case of low pitched roof we recommend adjustment brackets. It is also possible to install our collectors on building`s wall, a flat roof or on the ground, using our flat roof mounting kits.
