Collectors DRC 10 Brochure

Reg.-Nr.: 011-7S530 RSWISS Premium CollectorsELeading through experience1Collectors by AMK collectra AG – the new standard in using solar thermal energy AMK collectra AG, who pioneered the 360° absorber technology and developed the OPC10/15 high-per-formance collectors, recognised the advantages of three-dimensionally shaped absorbers more than ten years ago. Being awarded with the gold medal at the Exhibition of Inventions in Geneva, Switzerland, was the logical result of a brilliant implementation. AMK collectra AG has over 15 years of experience in deve-loping and producing evacuated tube collectors. Eva-cuated tube collectors are developed and produced in Switzerland. The quality is aligned with European standards of quality (Euro-Norm).All evacuated tubs collectors by AMK collectra AG have proven to be outstanding through maximum per-formance at minimum dimensions. In all our product series, the surface area of the absorber is larger than the gross surface area of the collector. This intentional target of maximising the absorber surface area is com-bined with the optimised refl ectors to guarantee the maximum absorption of direct and diffuse radiation.All collectors are equipped with avacuated tubes developed by AMK collectra AG. The vacuum tubes have a nine-layer, highly selective coating, and vacu-um loss is avoided completely due to the mechanical vacuum insulation.Did you know that the installation costs for conven-tional collectors can be up to 70% of the price of the collector? That is why the collectors by AMK collectra AG are very easy to mount. We offer you optimised mounting systems for all kinds of applications (pitched roof, fl at roof, facades, folded seam roof, fi bre cement roof, installation of the collectors in open spaces).In terms of performance, quality, easy installation and fl exibility, collectors by AMK collectra AG re-present a new standard. The collector technology by AMK collectra AG is protected by patent.The new standardAt the „International Fair of Installation Technology and Industry“ (March 28 – 31 2006) in Poznan (Poland) OPC15 Edition EU21 has won the gold medal for a technical innovative development.Solar Award Sweden 2007Solar Award Switzerland 2005Solar Award Switzerland 2006Application areas:DRC, OPC, OWR Standard preparation of hot waterDRC, OPC, OWR Heating support with high degrees of coverageOPC Process heat generationOPC Cold production for air-conditioning aided by absorption refrigeration technologyDRC, OPC, OWR For single occupancy houses, multifamily residences, hotels, industrial and commercial premisesOWR 12 optimizedwithoutreflector2The advanced absorber tubeAdvantagesFeb Additional benefit of DRC collectorsMar Apr May Jun Jul Aug Sep Oct Nov Dec 100% solar energy for hot water/heatingJan 100 90 80 70 60 50 40 30 20 10 + + Flat plate collectorsDRC collectorsEnergy requirementsSpecifications DRC 10Length: 2040 mmWidth: 1000 mmHeight (including frame): 102 mmGross surface area: 2.04 m2Active absorber surface area 360°: 2.73 m2Aperture area: 1.72 m2Weight: 50 kgAbsorber/glass: 360° Borosilicate 3.3Frame: AluminiumCoating: 9-layer, highly selectiveConnections: 4 x 1/2"Total content: 2.1 litresPermissible operating pressure: 10 barFlow rate recommended: 1.0 l/min./moduleA tube for all kinds of weather throughout the entire yearOur 360° absorber tube uses solar energy effi ciently throughout the entire year and provides a building with heat even when the weather is cloudy. Due to the 360° technology, the absorber collects direct and diffuse radiation to a much greater extent when com-pared to other collectors. In combination with the vacuum insulation, our 360° absorber tubes have reached previously unknown levels of performance. The construction prevents heat loss even at tempera-tures below zero.The vacuum between the glass tubes that are fused together cannot be broken, and the insulating effect remains unchanged. This vacuum enables the 360° absorber tube to return consistently high output data over the entire service life of the tubes.From the sun to the 360° absorber tube...Solar radiation – both direct and diffuse – penetrates the outer glass tube and is collected by the nine-layer coated, black absorber on the outer surface of the inner glass tubes....and from the tube to the solar circuitThe 360° absorber tube is separated from the solar circuit completely. The collected energy is transferred to the close-fi tting aluminium plate and to the copper pipes fi lled with heat transfer fl uid. Very large con-tact surfaces facilitate a rapid en-ergy transfer.Twice the benefi ts, more solar energy yield for the whole yearThe vacuum insulation and the large 360° absorber surface area ensure 100% solar energy coverage even in transitional periods. Ineffi cient heating systems are no longer needed. This combination collects highly useful energy from the sun, even at sub-zero tempera-tures in winter or under cloudy or rainy conditions.? The absorber tube is a uniform glass body. No metal-to-glass bonding.? The vacuum remains unbroken as an excellent insulation over the entire product life.? 360° absorber for the greatest possible surface area for energy absorption, utilises up to 80% of diffuse radiation.? The effi ciency remains at a constant, high level throughout the product life because the insulation and the absorber layer do not degrade.? Damage can be done to the tube only mechanically. A tube that loses vacuum, even without visible broken glass damage, can be detected immediately by the white condensation of water vapor inside the tube. This detection eliminates any gradual yield loss of the solar system.?

Solar calculation program Polysun, T-SOLMinimum loss of energy – through integrated hydraulics and vacuum insulationThe 1/2” collector hydraulics minimises energy losses by having no external piping and by having the inlet and outlet for the solar water circulation on the same side. With 1/2’’ hydraulics, it is possible to have the largest systems with the lowest pressure loss. The col-lector hydraulics are fully integrated, enabling com-plete fl exibility in attaching the hydraulics. Simple connection under balanced-pressure conditions. With the option of connections on the same or opposite sides for supply and return. Piping losses are mini-mised in the DRC because the piping is integrated into the collector.1/2” dual tube system– for small and large- scale systems– minimal pressure loss– 2 pre-installed sensor sleevesIntegrated collector hydraulics– no external piping– best insulation possible– parallel connectionsQuick installation– single-sided connection– in and out on the same side– only one roof penetrationMaximum energy yield – through 360° absorber tube and parabolic refl ectorThe large tubes and the refl ectors adjusted to them enable the DRC to gain large amounts of energy from direct and diffuse solar irradiation. The large-sized ab-sorber surface area is very important. AMK collectra AG provides the DRC10 collector with an absorber surface area of 2.73m2 for 2.04m2 of collector surface area. AMK collectra AG is the only manufacturer that has a greater absorber surface area in comparison with the gross sur-face area in all its products. This design makes it pos-sible to use diffuse energy irradiation optimally.No irradiation problem – long use of energy every dayThe right collector geometry of tube interval, tube diameter, and refl ector does the trick. From early mor-ning to late into the afternoon, the absorber is always irradia-ted ideally. The optimised white refl ector ensu-res that direct and indirect so-lar irradiation is refl ected to the back side of the absorber tube.Advantages4? The collectors can be installed for producing hot water in less than half a day.? Estimate for a hot water system: 1 person = 10 tubes = 100 l storage tank? Quick installation? No structural changes necessary? Expandable at any time? Self-explanatory mounting technology? Only standard tools need to be used? Later functionality already guaranteed at installation? Light, easy-to-handle materials? Modular, fl exible mounting technologyDRC – the collector with the simple, cost-saving installationA roof is a roof – that is why DRC collectors are mount-ed on the roof, not into it DRC collectors stand out not only because of their top-line quality but also their excellent design. At not even nine centimeters in height, they look elegant yet functional on every roof. Even large DRC collector arrays can be connected on one side. This means that the roof is penetrated at one single position for the piping to enter the house. No external piping is necessary on the roof.Of course, the DRC mounting system is also available for fl at roofs, fi bre-cement roofs and wall mounting. On a fl at roof, the DRC collector comprises a mounting rail with fl exible options for angle adjustments; the mounting is even faster than for a tiled roof.Multi-functional sliding rails make installing the DRC collectors extremely easy. At the same time, the hydraulic connec-tions of the collectors aretaken into account. Newly developed high-temper-ature, pressure-resistant steel expansion joints can be screwed on using stan-dard tools – no solder-ing, no welding, no spe-cial parts. All parts and steps are self-explanatory, and there is nearly no measuring necessary for the installer due to fl ex-ible mounting techno-logy.Installation in 7 steps, for example tiled roof:1. Remove the tiles from the rafters2. Install the mounting angle and put back the tiles.3. Screw on the mounting rail4. Fasten the collector hooks to the DRC collector5. Lift the DRC collectors onto the roof and hook them on6. Tighten the DRC collector with one single screw7.

DRC collectors are burner and heater-friendly; they last longer, run with less faults and re-quire less maintenance because the ineffi cient stop-and-go operation of the burner is avoided. Additional benefi ts in all areas: lower operating costs and high energy savings (70–80%, depending on the system combination), longer useful life and thus lower in-vestment costs.Oil/gas heating and DRC collectorsTurn off your oil or gas burner for six months Then your burner will run more effectively during the win-ter and transitional periods. Maintenance efforts, in-vestment and consumption of oil or gas decrease.Wood heating and DRC collectorsThe ideal combined system: wood stove with a stor-age tank readily available that can be used for solar energy. Additionally, the consumption of fi rewood is greatly reduced which simplifi es handling as well.Heat pumps and DRC collectorsThe combination of a solar system and a heat pump uses electrical energy even more effi ciently. The heat pump is not needed in summer and is supported by the solar system in winter. That pays for itself twice over.What is your DRC combination?DRC collectors optimise your building’s technology. They can be combined with conventional and new renewable energy systems such as controlled ventila-tion systems.Take advantage of a DRC system combination ? Saving fossil fuels by optimising the solar system? Much lower maintenance costs for the burner from longer operating times? Burners last longer because of optimised burner operating times? DRC solar systems are suitable for new buildings and renovation of energy systems? DRC solar systems become the key component of modern building technology? DRC solar systems can use all new technologies to connect to systems even more useful for customers? DRC solar systems produce solar power throughout the entire year; greater degree of system effi ciency due to the most advanced technologyRepresented by:The manufacturer reserves the right to make modifi cations at any time that contribute to the technical progress of the product.5Intelligent DRCsystem technologyDRCFlyerENG020913expansion tankAMK-SOLAC Systems AGLagerstrasse 30CH-9470 Buchs SGTel.: +41 81 750 17 17Fax: +41 81 750 17 18www.amk-solac.com
