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 stratified 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 fibers
with leatherette cover.
