SAFETY ELEMENTS

Temperature Pressure Relief Valve prevents damage to a solar system caused by exceeding the max. permissible pressure. In case of a breakdown the system might overheat, making the pressure rise extremely. 6 bar Temperature Pressure Relief Valve, 1/2", female, up to 160°C Code: 1616
Automatic Air Vent removes air and gases from the heat carrier. It is placed at the highest point of a solar system (near a collector).  Air Vent up to 150 °C, 3/8", up to 10bar Code: 6118
hermostatic Mixing Valve for DHW limits the max. required DHW temperature (adjustable between 30 and 60°C). Water temperature inside a tank fluctuates due to the effects of solar collectors and can reach even very high temperature; the valve cools down the hot water by mixing it with cold water at the outlet.  MT52 - Thermostatic valve for DHW, 30-70°C, 1" M Valve housing and inner components are made of brass with protection against corrosion and scale. Gasket: EPDM Code: 6726 MT52HC - Thermostatic valve for DHW for high flow rates, 20-70°C, 5/4" M Max. working temperature: 90°C Max. working pressure: 10 bar Valve housing material: brass Inner components material: brass Gaskets material: EPDM, NBR Housing with a protective layer against scale sediments Dynamic working pressure: 0.5-5 bar Max. inlet pressure difference: 2 bar Range of continuously regulated temperatures: 20-70°C Temperature stability of mixed water: 4 K max. (at hot water temp. change of 20 K) Noise level: class 2 Mounting position: any Spring safety closure for case of cold water supply failure (for mixed water temp. of 40°C) Weight: 0.9 kg Special function: can be used as a diverter valve (reversed water flow) Code: 7079
Air separator separates effectively even small air bubbles from the antifreeze liquid and thus increases the efficiency of the entire solar system. It can be used separately or as a complement to FlowCon B Pump Group, or it can be also used for FlowCon S (S/Pro) Pump Group, creating thus a 2-tube assembly. Vertical Air Separator with manual air discharge valve Code: 6888 Horizontal Air Separator 3/4" with outlet for an air vent Code: 7076 Horizontal Air Separator 1" with outlet to for an air vent Code: 7077

AEROFLEX INSULATION

Aeroflex SSH Temperature insulation is made of synthetic rubber (EPDM) without addition of PVC and FCKW. It is soft and flexible, withstands temperatures up to 175°C for a long time, is highly UV-, weather- and ozone-resistant. Excellent insulating properties (thermal conductivity at 40°C is 0.04 W/mK).

STORAGE WATER HEATERS AND ACCUMULATION TANKS

They serve for storing the energy from solar collectors. The energy is stored when the sun shines and retrieved when there is no sunshine. In the period of insufficient sunshine the missing energy must be replenished from another source. In case of heating sanitary water, it can be done in two ways:
1. It can be heated by means of an electric heating rod (or by a boiler through the second heating coil inside the tank), 
    in such a case the solar system serves as an independent source of hot water.
2. The solar system can be used for pre-heating the water for another, currently used method of sanitary water heating 
    (electric storage water heater, instantaneous water heater, heat pump, gas fired boiler etc.); in this case the tank volume 
    as well as the solar energy can be both fully utilized.
In both the cases sufficient amount of hot water is available all year round and thanks to an electronic regulation its operation is fully automated.
