- A few dozen litres of water in the recovery tank
are used to decant any foam (dangerous for the
suction motor). The cone under the top cover of
the tank that separates the foam area from the air
suction area acts as another decanting system. The
inner area of the cone is "sealed" at the bottom
against the rising water. The air, from which the
foam - that remains outside - has been removed, is
vacuumed from the pores at the top. The traction
system is designed for the machine weights, ma-
king the machine responsive and easy to handle.
- Robust construction. The frame and the squee-
gee, built with thick sheet metal - thickness 6 mm,
8 mm, 10 mm up to 20 mm – are laser cut and wel-
ded. The brush plate is made from 15 mm ship's
sheet metal, with a surface treatment that protects
the plate and the paint for thousands of hours in a
saline fog. All screws are made with stainless steel;
the tanks (body) are made with 7-8 mm thick
shockproof polyethylene. Everything is simple and
very strong, without any other complicated designs.
- The battery compartment can house very large
batteries, which guarantees extended running time.
- The suction motor is housed inside the machine,
thus reducing operating noise to a minimum.
- The recovery tank is very easy to clean due to the
lack of the characteristic difficult access points of
recovery tanks located in a lower position.
5.1.2 BATTERY
To make handling easier (considering the weights
involved) and to avoid situations that may be dan-
gerous for the batteries and for the operator, we
offer only box-type battery units for this machine.
This power supply unit configuration not only is ro-
bust, but is necessary in order to offer high perfor-
mances (Ah capacity).
Regardless of the type of construction, battery per-
formances are indicated with the term capacity,
which always refers to a discharge period. Another
important value is the number of possible dischar-
ges. The capacity is expressed in amps per hour
(Ah), while the discharge period is generally indi-
cated as 20 hours (C20 or 20h, or not expressly in-
dicated)
or
5
hours
discharge/charge cycles indicate the number of
times that the battery can hold a charge under the
best conditions, i.e. they indicate the useful battery
service life complying with all the necessary mea-
sures.
Therefore, the capacity of a battery varies depen-
ding on how fast it uses energy (current). That's
why there's such a variation in the capacity values
expressed as C5 or C20. These factors must be
taken into account when comparing products avai-
lable on the market with our own.
This machine can be equipped with two types of
batteries that differ in terms of their construction
and features.
(C5
or
5h).
The
- Pb-Acid battery with tubular armoured modules
(box type): the electrolyte level in each element
must be periodically checked!
!
(
) If one element is no longer covered by the acid
solution it will oxidise in 24 hours, thus permanen-
tly affecting that element's performance.

(
) Refer to the battery manual to avoid physical
damage and economic loss.
- Gel module battery (box type): this type of battery
is maintenance free and does not require special
environments for recharging (since it does not emit
any harmful gases); therefore, it is highly recom-
mended.
!
(
) It should not be taken for granted that batte-
ries and battery chargers with the same technical
features as those we offer will produce the same
results. Only perfect compatibility between these
elements (Pb-Acid batteries, gel batteries and bat-
tery chargers) will safeguard the performances, the
service life, the safety and the economic value in-
vested.
5.1.3 BATTERY CHARGER
This type of high-frequency battery charger effi-
ciently charges batteries, extending their operating
and service life. In addition, because they can be
configured with optional smart cards (magnetic
badges), it is a very versatile solution that reduces
the number of chargers required in the warehouse.
The same battery charger can be used for both Pb-
Acid batteries and for gel batteries.
The information indicated on the digital display can
be used to always keep the charging process, the
battery and the battery charger under control (read
the specific manual for more details).
