2. DESCRIPTION OF DEVICE
The tanks serve for accumulation and subsequent distribution of the heat energy from solid fuel boi-
lers, heat pumps, electric boilers, etc. The accumulation tanks ATTACK AS, HRS, TUVS and SS are acces-
sorized with an extra exchanger for aheat source with separated circuit (e.g. for solar system). The accu-
mulation tanks ATTACK HR, HRS, TUV, TUVS are equipped with abuilt-in system for D.H.W. preparation.
2.1. TYPES
The AK and AS line of the accumulation tanks with the volume up to 5.000 land option to install
the electrical heating body.
The HR and HRS line of the accumulation tanks with the volume up to 2.000 land abuilt-in D.H.W.
tank and option to install the electrical heating body.
The TUV and TUVS line of the accumulation tanks with the volume up to 2.000 l, abuilt-in instanta-
neous D.H.W. warming through acopper exchanger and option to install the electrical heating body.
The Sand SS is aline of astratied storage tanks with the volume up to 2.000 land option to install
the electrical heating body.
2.2. THERMAL INSULATION
The accumulation tanks are supplied with 100 mm wide soft insulation made of polyester bers
with leatherette cover.
2.3. SPECIFICATION
Max. operating pressure in the accumulation tank: 3 bar
Max. operating temperature in the accumulation tank: 95 °C
Operating pressure in asolar exchanger: 9 bar
Max. operating pressure in the D.H.W. tank: 6 bar
