3 DESCRIPTION OF THE
APPLIANCE
B
IDRA N DS
solar storage cylinders are double coil
units designed for installation in domestic hot water pro-
duction systems heated by solar collectors. They come in
capacities 1500, 2000 and 2600.
The most important technical features of these solar stor-
age cylinders are:
- The cylinder and coils are specially designed and
shaped for optimum performance in terms of stratifi-
cation, heat exchange and replenishment times
- vitrified cylinder lining, bacteriologically inert for max-
imum hygiene of the water, reduced lime scale de-
posits and easy cleaning
- CFC-free polyurethane insulation and an elegant ex-
ternal casing reduce heat loss
- Water fittings are available at different heights, per-
mitting different hot water generators to be used with-
out reducing the stratification effect
- a flange for easy cleaning and maintenance of the
anti-corrosion magnesium anode.

storage cylinders can be connected to a
special solar regulator and can be integrated in solar heat-
ing systems in which

boilers or water heaters provide
supplementary heat.
