Products - ALCAD Battery
In off-shore oild and gas application utilities, switching sub-stations and in other remote locations, gaining access for battery maintenance can be difficult hazardous and expensive. Battery operation that is simple, with reliable performance, long life and minimum maintenance is vital.
Vantex is the solution - an innovation in hte design and manufacture of advanced, high technology batteries for operation particularly in high temperature conditions.
Vantex is new
Alcad has more thqan 100 years experience in the design and manufacture of batteries to meet particular industrial needs. The ground-breaking Vantex concept provides exceptionally reliable performance, even at very high operating temperatures, but requires the minimum of maintenance.
Its well-proven, robust Ni-Cd pocket plate cnstruction and low maintenance concept provide a battery of superior capability. This profile suits particularly installations where access is restricted and where maintenance visits must be minimised.
Vantex is offered in a very wide capacity range, from 8 Ah to 1700Ah, and with a choice of two plate types.
L RANGE - suitable for low discharge times of between 3 and 100 hours,
M RANGE - designed to manage mixed loads of high and low discharge rates for between 30 minutes and 3 hours.
Long life at high temperature
Vantex shows good endurance with excellent results, with both cell types exceeding by more than 4 times the endurance test of IEC 62259.
The battery of performs reliably at temperatures of up to +40°C ( +104°F), and in extreme conditions to -40°C and +70°C (-40°F to +158°F). Vantex has a service life expectancy of 12 plus years at +40°C ( +104°F) and of 20 plus years at +20°C ( +68°F). It can never suffer from 'sudden death' owing to the total reliability of Ni-Cd electrochemistry.
Additionally, M type cells achieve more than 90% capacity even at +40°C ( +104°F) after a constant charge at 1.43 V/cell for 15 hours with a charge current of 0.1C5A. Excellent chargeability at low charge voltage reduces downtime load voltage window and ensures the battery returns quickly to duty, maintaining application reliability.
Easy to handle
The optimised design of Vantex includes several features to make transportation, installation and operation fast and easy.
Up to six cells are configured in series and assembled in blocks to enable easy handling. As Vantex cells are always factory-filled with electrolyte, rapid installation on site means the battery and application can be brought quickly into operation, minimizing downtime.
Long storage periods
When filled, Vantex may be stored for up to 2 years in normal conditions without affecting future performance.
Only one top-up during life
The Vantex design enables highly efficient gas recombination of more than 90% - far beyond the requirements of IEC 62259 - allowing very low gas emissions and water consumption. As a result, Vantex may require only one topping-up operation during its entire service life.
Very rapid charging
Charging of Vantex may be carried out with either single or two level methods.
Single level low voltage charging without temperature compensation enables Vantex to be charged and discharged within a low load voltage window. *except for low temperatures
For single level charge
- 1.43 ± 0.01 V/cell
For two level charge
- float level: 1.43 ± 0.01 V/cell
- high level: 1.45 ± 0.01 V/cell
Built and tested to quality standards
Vantex is manufactured to the highest international quality standards in production facilities qualified to ISO 9001and ISO 14001.
The design compiles with IEC 62259 and far exceeds the requirement for a minimum 70% gas recombination level.
And Vantex is safe, in line with the requirements of EN 50272-2. Componets such as insulated cable connectors and end lug covers meet IP2 level to ensure protection against electric shocks.
Quality support, too
A comprehensive service, technical and training backup is provided by Alcad's global sales and after-sales support network.
Block configuration
For serial connection of blocks on racks or on shelves, always use blocks with an even number of cells. This gives short, straight interblock connectors. When a block with an odd number of cells is necessary, it should be placed at the end of a cell row.
Disposal and recycling
Ni-Cd batteries provide an environmentally responsible solution to growing demands for autonomous electric power. Alcad prioritise environmental care through control at every stage of battery's life - from design andproduction to end-of-life collection, disposal and recycling. The simple and unique nature of components make Alcad batteries readily recyclable and this process safeguards valuable natural resources. Alcad works in partnership with collection agencies worldwide to retrieve from pre-collection points and recycle spent Alcad batteries. Visit our web site fopr further details: www.alcad.com
Ni-Cd batteries should be treated carefully in accordance with local and national regulations and must not be discarded as harmless waste. Alcad representatives can assist with further information on these regulations and with the overall recycling procedure.
