Monoblock Aluminum Case Manufactured by Pressing Method ... Since the efficiency of the selective absorber in Euroline Series Solar Collectors is quite high, these collectors can be preferred in regions where sunlight is less. The absorber surface consists of selective aluminum plate and copper pipes. The distribution of copper pipes can be manufactured as VSH / HSH Grid or VSM / HSM Meander (single curved channel).

Trendline Series Solar Collectors are produced with high technology. Absorber surface: Selective copper or aluminum in the form of Full Plate or Fin Plate . It consists of plate and copper pipes. Trendline Series Solar Collectors are produced alternatively with both ultrasonic welding technology and laser welding.

Ecoline Series solar collectors are solar collectors with various absorber plates made of aluminum, copper-aluminum or pure copper material, with a black matte painted upper surface. The absorber plate is the most important part of the solar energy system. This plate allows the radiation from the sun to be transferred as heat energy to the heating fluid inside it.

Istek Boilers and Accumulation Tanks transfer the heat obtained as a result of the bivalent use of solar energy or boiler heating systems to the drinking water with the help of serpentines.

Forced circulation solar energy systems with Double Serpentine boilers enable the heat obtained as a result of using solar energy to be transferred to the domestic water with the help of the lower serpentines of the boiler, and also, in cases where solar energy is not sufficient, to the domestic hot water with the help of the boiler or combi boiler with the upper serpentine. They are devices used to transfer heat and thus obtain domestic hot water under uninterrupted comfortable conditions. An electric heater can be optionally installed as a third energy source.

Istek, large-volume, large Accumulation Buffer Tanks have been developed for systems with different zoning that require high energy storage. Various versions offer different system solutions with multiple exchanger configurations ranging from 800 to 5000 liters.

Istek Thermosiphon Solar Energy Systems are systems that operate by feeding pressurized cold water directly from the city network, without an additional float tank. These types of systems are systems that operate under pressure. Therefore, the system reaches the network pressure before it even starts operating. When the system starts to work, as the temperature increases, the pressure also increases. According to the closed vessel principle, as the pressure increases, the temperature of the water in the storage tank of the system reaches high levels.

ISTEK Vacuum Tube Solar Energy System works with natural circulation as its working principle. Cold water supply is a float system. It is a highly efficient system thanks to selective surface vacuum tubes with high radiation absorption and vacuum environment.

Installation is now very easy with Specially Developed Universal Type Mounting Kits .
