Hawker
The hawker perfect plus motive power batteries provide a high
level of power and reliability for all industrial truck
applications, from simple applications with a low capacity loading
up to heavy duty multi-shift applications.
Why “plus”?
Compared to the former perfect range, the Hawker perfect plus
cells provide higher efficiency in discharge achieved by advanced
components used in the construction of the positive plates. The
sizing of the positive and negative plates has been optimized
according to the volume available in the cell boxes. The process of
filling the positive plates has been improved. All these technical
enhancements have enabled an increase in the cell capacities while
keeping the same exterior dimensions. The Hawker perfect plus range
is at the highest technology level and has a very high efficiency.
This improvement integrates the European harmonization of the DIN
and BS ranges. This range meets the dimensions of standards DIN/EN
60254 and IEC 254-2.
Cell construction
All Hawker perfect plus cells use the robust tubular vented
technology (PzS). The positive electrodes are diecast tubular plates
(PzS) and advanced components used in their manufacture provide
increased efficiency. The negative plates are flat pasted plates.
The separator is of the microporus type. The cell box and lid are
made from high impact, temperature resistant polypropylene and are
heat-seal welded to prevent electrolyte leakage.
Terminals
The special design of the terminals ensures that no
electrolyte can leak from the cells.
Cell connectors
The cells are joined by fully insulated flexible and halogen
free connectors. The bolt-on connectors allow cells to be replaced
or moved without excessive work.
Flip top plugs
Flip top plugs with electrolyte level markings are fitted.
These allow adequate escape of charging gasses and provide a safe
anti-surge baffle for the electrolyte during operation.
Lid
The lid is equipped with holes for installation of
electrolyte mixing system, these can also be used for temperature
sensor tests.
Hawker aquamatic
The aquamatic water refill system makes it possible to top up
all the cells from one central point through an integrated system.
The aquamatic vent plugs automatically ensure the optimum filling
level and also allow the measurement of electrolyte specific
gravity. The aquamatic kit can be expertly fitted at the factory and
on site.
Definition of application fields
1-
low duty
single shift with light operation and discharge lower than
60% C5. electrolyte TC about 30C
2-
Normal duty
Single shift with discharge up to 80% C5
3-
Heavy duty
-
Single shift with discharges of 80%C5 and high discharging
currents.
-
Opportunity
charging to augment the useable capacity
-
Multi-shift operation with or without battery changes
-
High ambient temperature
Electrolyte mixing
The Hawker
electrolyte circulation system, using the AirLift principle,
consists of a pipe system which is fitted in the cells. A diaphragm
pump sends a low rate airflow into the cell which creates a
circulating air stream inside the cell box. This system prevents
electrolyte stratification and the battery charging is optimized.
Benefits
Hawker perfect plus
-
increased capacities in same dimensions
-
higher running time and battery availability
-
European harmonization of capacities and sizes in DIN and BS
ranges
Hawker perfect plus
with electrolyte mixing
-
no electrolyte and temperature stratification during partial
or complete charging process
-
optimal charge acceptance by positive and negative electrodes
and therefore uniform plate stressing
-
charging time shorter by up to 30% and energy savings of up
to 20% compared with conventional charging processes
-
minimized gassing phase, reduced sludging and water
consumption reduced by up to 70%
-
temperature rise during charging is up to 10C lower, allowing
use in warm ambient conditions
-
more rapid battery availability for the same nominal charging
current due to shorter charging time and therefore higher battery
utilization rate in multiple shift operation
-
higher performance and longer battery service life in heavy
operation particularly with opportunity charging
-
longer maintenance intervals, lower maintenance costs.
