AquaTank EM (7bar)0 pages

Hot water storage tank, 300-3000 litre
AquaTank EM (7 bar)
AquaTank EM is our range of enamelled (glass lined) hot water
storage tanks for customers who prefer the hygienic coating
of enamel which also allows operation with chlorinated water.
This leaflet describes cylinders available as standard in capacities
between 300 and 3000 litres. Furthermore we offer also
vessels up to 1000 litre capacity rated for 10 bar operation
pressure with standardized dimensions.
Pressure vessel code
AquaTank EM meets the requirements of the PED 97/23/EEC
code. Other pressure vessel codes can be offered on request.
Charge heat exchangers reduce power demand
AquaTank EM is designed for use in combination with charge
heat exchangers. The AquaTank is then employed to store
drinking quality water in facilities in which the water flow is
not constant – where sudden high demands occur more or
less regularly, such as in apartment houses, sports centres,
schools, hotels and hospitals. With a charge heat exchanger,
the power demand can be substantially reduced compared
to a separate coil heater, since the AquaTank acts as a buffer
to meet the power peaks occurring at high water flow rates.
Following such high water demand, heating takes place
very quickly, because the water that has been heated by the
charge heat exchanger is stored at the top of the tank. The recovery
period is short, unlike that of a traditional coil heater in
which the entire heater volume must first be reheated before
the user obtains the domestic hot water comfort provided by
an AquaTank with charge heat exchanger.
Flexible energy source
All types and sizes of the AquaTank EM can be equipped with
electric immersion heaters. The immersion heater are fitted
directly to the inspection opening/man hole, which simplifies
the installation work.
High effectiveness for maximum hot water
The effectiveness of this type of storage tank from which hot
water is drawn depends on its ability to keep the hot water
separated from the cold water admitted into the tank.
The AquaTank is particularly good in this respect because
of its internal tube arrangement. The incoming cold water is
distributed
gently across the bottom of the tank, which prevents
it from mixing with the hot water. The hot water then is
drawn from the very top in the centre of the cylinder. Moreover,
since vertical hot water storage tanks are more effective than
horizontal ones, the AquaTank is of upright design.
Effective and environment-friendly insulation
The insulation is made of 50mm mineral wool and covered
with a PVC-jacket. As option we offer also 100 mm mineral
wool and an aluminium-plate cladding. The insulation is very
easy to remove and refit, which makes the unit easy to transport
into and out of the premises.
