ACCUMULATION TANKS
DESCrIPTION
The accumulation tanks
ATTACK Hr, HrS
are made from the quality steel
and serve for accumulation of the heating water as well as for preparation of
the D.H.W. by an internal enameled exchanger. The
ATTACK HrS
model is
accessorized with an extra exchanger to be connected to the solar system.
Tanks of this type have a built-in magnesium anode in the D.H.W. tank
to increase resistance against corrosion. The manual deaeration valve is in-
stalled in the upper part.
ATTACK Hr:
9× socket G 1 ½", 6× socket G ½"
ATTACK HrS:
9× socket G 1 ½", 6× socket G ½", 2× socket G 1" – solar circuit
