The KS2000 TP flat plate solar collectors are intended for hot domestic water systems in 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 systems in single-family homes.

Flat plate solar collector KS2000 TLP is an uncompromised solution in terms of construction and parameters among flat plate collectors. The absorber is made entirely of copper (Cu-Cu) and welded with ultrasonic welding. High efficiency is achieved through highly selective coating (PVD), glass providing high permeability to solar radiation U1 and full thermal insulation of the casing.

KSOL-2/2000/2100 Universal Handle (for first two collectors) is made of aluminum and galvanized steel. It is used for mounting flat plate collectors on roofs  or other planar surfaces with inclination of at least 30° with respect to horizontal plane. It is powder painted in grey and brown (RAL 7022).

KSOL-1/2000/2100 Universal Handle (for an additional collector) is made of galvanized steel and aluminum. It is used for mounting flat plate collectors on roofs or other planar surfaces with inclination of at least 30° with respect to horizontal plane. KSOL-1/2000/2100 Universal Handle is painted in RAL 7022 (grey and brown).

The KSR10 evacuated tube solar collectors (commonly referred to as vacuum solar collectors or tube solar collectors) are among the most efficient solar collectors in the market. The use of single-wall evacuated tubes, which are additionally covered with an anti-reflection coat, ensures high optical efficiency on the level of 85% in relation to the absorber`s surface area. The evacuated tubes, made by the German expert company NARVA Lichtquellen GmbH + Co. KG, take advantage of patented innovative technical solutions.

The 2xKSR10 evacuated tube solar collector is designed based on two KRS10 collectors connected to each other. Due to the way of its installation, it constitutes a basis for expansion of a solar collector bank by adding more KSR10 collectors. The efficiency and loss coefficients given in the table refer to the active surface of the collector.

Termsol Eko heat transfer fluid is a solution of water and non-toxic polypropylene glycol at 33% concentration. It also contains a set of inhibitors, which guarantee anticorrosion properties and extend longevity of the mixture and the whole solar installation. The freezing temperature is -25°C. Available in the size of 5kg.

The air heat pump is designed for supplemental tap water heating. It may be used in combination with both new and old installations with a water heater of any capacity. The heat pump is particularly recommended in systems involving heaters equipped with electric heating elements or solid-fuel boilers that should not be used outside the heating season for economic and ecological reasons. A completely equipped and fully automatic pump, ready for direct connection without additional devices may help save 50-60% of water-heating energy per year. It may be installed both indoors and outdoors, with the reservation that outdoor installation requires the use of a freeze-resistant medium. The control panel may be mounted indoors. The installation includes the following elements: compressor heating system, heat exchanger and circulating pump for tap water, enclosed in powder-coated steel casing. Standard equipment includes an external control panel.

Solar set HEWALEX 2 TLPAm-200 is designed to heat C.W.U. for 2-4 persons. The set includes all the elements necessary to built the instalation. The exception are the fastenings, which need to be chosen individually to the place of assembly as well as pipes which connect the collector with the heater. Using KS2000 TLP Am flat plate collectors in a complete set, guarantees maximum durability and maintenance-free operation. All the components of the set that are in contact with heat transfer fluid and aluminum are made of a dedicated for such purposes aluminum and stainless steel alloy. This ensures safe operation of the whole solar system. In order to quickly and conveniently connect the battery of solar collectors with a water heater it is recommended to use a stainless steel elastic tube, which can be found in our offer.

KSL Masking Profile is dedicated to cover the break between flat plate collectors in a battery. It improves the aesthetics of the collectors by achieving a uniform plane and additionally it partially protects the connections between the collectors from atmospheric conditions.
