DRAZICE NAD v1 Storage Tank
OPERATIONAL MOUNTING REGULATIONS
DESCRIPTION
Storage tanks are used for accumulating of excessive heat received from the
heat source like, for example, a solid fuel boiler, a heat pump, solar
collectors, fireplace inserts, etc. Some tank types allow connecting more than
one heat source at a time.
NAD type storage tanks are used for accumulation of heat in heating systems. Incorporation of the storage tank into a heating system with a boiler using solid fuel allows for optimum running of the boiler at a favourable temperature during boiler operation. The benefit comes mainly during the optimum running period (i.e. with maximum effectiveness) when the excess heat that has not been taken off is accumulated in the tank.
Tanks and also possible pipe exchangers are manufactured from steel with no treatment of the internal surface, the outer surface has a protective coating. Tanks are equipped with removable 80 mm insulation – NEODUL LB PP. Tanks are manufactured with volumes of 500, 750 and 1000 litres. Individual versions are also equipped with one or two 1.4 m2 pipe exchangers including inspection apertures with an inside diameter of 182 mm with the possibility for installation of in-built TPK electric heating units.
The vessels are not intended for storage of HUW – hot utility water.

DESCRIPTION OF INDIVIDUAL VERSIONS
NAD v1
Storage tanks can be provided with one to three flanges. The flange with screw
gauge 210 mm can be used for mounting built-in TPK flange electric heating
units. The flange is blocked off in the standard version. The G 6/4″ extension
pipe cab be used for mounting of the TJ G 6/4″ electric heating unit. Supplied
with insulation with a thickness of 80 mm.
NAD v2
Storage tank can be provided with G 6/4″ extension pipe. The G 6/4″ extension
pipe cab be used for mounting of the TJ G 6/4″ electric heating unit. Supplied
with insulation with a thickness of 80 mm.
NAD v3
Storage tank with a flange with screw gauge 210 mm and extension pipes or only
with extension pipes. The flange with a screw gauge of 210 mm can be used for
mounting built-in TPK flange heating units. The flange is blocked off in the
standard version. Supplied with insulation with a thickness of 80 mm.
NAD v4
Storage tank with a flange with screw gauge 210 mm for mounting built-in TPK
flange heating units and one 1.4 m2 exchanger for further heating system
connection (e.g. SOLAR). The flange is blocked off in the standard version.
Supplied with insulation with a thickness of 80 mm.
NAD v5
Storage tank with a flange with screw gauge 210 mm for mounting built-in TPK
flange heating units and two 1.4 m2 exchangers for further heating system
connection (e.g. SOLAR). The flange is blocked off in the standard version.
Supplied with insulation with a thickness of 80 mm.

PROPOSAL FOR SIZE AND CONNECTION OF THE STORAGE TANK TO A HEATING SYSTEM
Proposal for the optimum size of the storage tank is made by the designer or a
person with sufficient knowledge for design of heating systems.
Mounting is carried out by a specialist company or person who can confirm
mounting in on the guarantee certificate.
BASIC TECHNICAL PARAMETERS
Maximum operational pressure in the tank is 0,3 MPa. Maximum temperature of
heating water in the tank is 90 °C.
For versions 4 and 5 also:
Maximum operational pressure in the exchanger is 1 MPa, maximum temperature of
heating water in the exchanger is 110 °C.
We recommend you use the product indoors with an air temperature of +2 °C to
+45 °C and relative humidity of max. 80 %.
No stop fitting can be put between the security fitting of the heating circuit
and the accumulation tank!!!
The appliance has to be mounted at a convenient place, it means that the appliance must be easily available for potential necessary maintenance, repair or replacement, as the case may be.
Heat insulation
80 mm thick insulation NEODUL LB PP. The top cover covers of flanges and hole
caps are integral components. Insulation is supplied in separate packing.
We recommend you use insulation for operation at room temperature. At
temperatures markedly lower than 20 °C the insulation shrinks and cannot be
fitted.
