Collector; Accumulation Tank (Cylinder) - SOLE EUROSTAR ECO Series Installation & User Manual

2.2. Collector

The collectors are manufactured in 4 sizes with nominal area of 1,50m
absorbers of the collectors are made by copper tubes and the fins area by selective aluminum fins. The fins
are welded to the tubes by laser welding. The frame of the collector is made by extruded aluminum epoxy
oven painted to resist ambient conditions.
The glass cover is a "prismatic securit" glass of 3.2mm thickness for maximum penetration of solar
irradiation. At the back and sides of the absorber there is sufficient insulation of rock wool and glass wool to
minimize heat loses and to resist stagnation temperatures.

2.3. Accumulation tank (cylinder)

The solar accumulation tank is an indirect (double circuit) hot water horizontal cylinder. The inner surface is
o
enameled at 850 C to guarantee potable sanitary water for long life. Additionally it is protected against
rusting with a large magnesium anode.
The ecologic polyurethane foam insulation guaranties minimum thermal loses even at very low ambient
temperatures. The external cover of the tank can resist any extreme weather conditions for life. The internal
heat exchanger with large surface guaranties the energy transfer to the domestic hot water.
The hot water exits from the hottest zone (level) of the tank. At the same time equal quantity of cold water
enters the tank at the coldest zone (level). The solar tank can be optionally (accessory) equipped with
immersion electric heater (electric element) for use only for emergency situations. The immersion electric
heater is available in 2 kW or 3kW or 4 kW at 230 Volt. It is equipped with control thermostat set at 60
safety thermostat (thermal cut out) manually reset.
The safety valve only opens to discharge when the system pressure exceeds 10bar in the form of water.
