SKU#:
WRWHS-CARAT
The
new tank generation of CARAT rain-water underground tanks have
been specially developed for rain-water harvesting.
The
CARAT underground tank is unlike any other underground tank in the world. It is
the largest tank of its kind to be manufactured by injection compression
molding. This technique provides the tank with unbeatable stability and
ensures that each component is produced with the highest of accuracy.
Unlike other underground tanks, the wall thickness is equal in all areas of the
tank. The production tolerances are kept to a minimum, resulting in a
product of the highest quality, which is strong, accurate, reliable and
extremely user-friendly. To manufacture the CARAT, one of the worlds
largest injection molding systems had to be developed.
Easy
and safe assembly
Easy
and safe assembly
- The patented quick connection
(illustrated in green), allows the Carat tank to be assembled without screws
in only few minutes. Disassembly is possible at any time.
- The first-class EPDM material
used in the profile seals (illustrated in yellow), has been laboratory tested
to last more than 25 years.
- The centering bolt
(illustrated in orange) assures the accurate and easy assembly of the two half
shells preventing any leaks
More
advantages
- Variable burial depth: 30" to
42" (59" Max. with optional dome extension and "Maxi" telescopic
riser)
- Unique in the world! – a global
innovation: unique manufacturing process produces the highest stability due to
latest techniques
- Unique fit accuracy of the
components thanks to new production process
- Consistent quality due to TÜV
safety testing and production monitoring
- Groundwater stable up to the
middle of the tank due to extremely rigid construction
- Made from high quality Duralene;
easy to recycle
- Can be expanded as
required
- 31.5" Manway opening
Flush
with ground level (2 seals)
The
Carat S underground tank has numerous seals to effectively stop dirt getting
into the tank. This means that seepage water cannot get into the tank and, thus,
dirt particles cannot contaminate the rainwater. The seals are in the
intersection between the tank and the tank dome and between the tank dome and
the telescopic dome shaft. All supply pipes connected to the tank dome are also
sealed with five lip seals as standard.
Application:
- The global innovation – the new
tank generation of the Carat rainwater underground tanks have been specially
developed for rainwater harvesting
- Frost-proof installation
underground
- Groundwater stable up to the
middle of the tank due to extremely rigid construction The tank that
turns its head for you
The
CARAT underground tank has a rotating tank dome. The tank dome can be aligned
with the connections independently of the tank – this makes installation much
easier! All installation pipes are connected using the five standard lip seals.
The CARAT telescopic dome shaft connects the system to the ground surface. The
height of the tank can be smoothly adjusted to suit the local conditions and it
can be tilted by 5°. The whole system is flush with ground level.
Logistical
advantages of the CARAT:
The
CARAT tank consists of two half shells which can be stacked on top of each
other, allowing multiple tanks to be stacked on a single pallet for shipping.
For example, it is possible to stack five 1,700 gallon CARAT tanks on a single
pallet. This allows a standard 40 ft. shipping container to house a total tank
volume of up to 34,000 gallons! The tanks' unique stacking feature directly
reduces transport costs and environmental impact from vehicle
emissions
