SiS Li-Ion 90 Safe Pro battery charging safety cabinet – LaCont without fire suppression system

The LaCont battery cabinet LI-ION SAFE PRO was specially developed for the active and passive storage of lithium batteries, with GS certification according to test principle EK5 / AK4 22-01 and a real fire test of the cabinet equipped with lithium batteries carried out at MPA Dresden.

Due to the increased requirements of the GS test, the LI-ION SAFE PRO has a tested fire resistance of 90 minutes according to DIN EN14470-1/-2 from outside to inside and 90 minutes according to DIN EN 1363-1/-2 from inside to outside. The self-closing doors are additionally permanently function-tested according to DIN EN 16121 and DIN EN 16122.

By means of all-round, automatically expanding fire protection seals in case of fire and permanently self-closing doors, the LI-ION SAFE PRO not only protects against fires inside the cabinet, but also protects your stored goods from fires from outside. The risk to persons from the possible release of explosively burning or toxic gases and smoke is to be minimised. The aim here is to gain time for the evacuation of persons in the vicinity and for the initiation of extinguishing measures by the fire brigade.

Further standard equipment includes an integrated ventilation system to prevent heat build-up in the cabinet, a 5-litre collection tray made of steel sheet and manufactured according to AwSV, 4 height-adjustable grid shelf storage levels with a load capacity of 75 kg each (with evenly distributed load), as well as a plinth with a cover for easy transport.

The control unit included in the scope of delivery, with optical and acoustic status messages and fire detectors, monitors the storage process of the Li-ion batteries. In case of fire detection inside the cabinet, the power supply and the integrated ventilation are completely shut down, and an optical and acoustic alarm is triggered. A potential-free contact allows for signal forwarding to a control centre.

Construction from non-combustible material including coating (body in aluminium colour / doors RAL 1023 – traffic yellow), galvanised steel sheet base tray according to AwSV, 5 litres collection volume.
Automatically closing doors, permanently function-tested according to DIN EN 16121 and DIN EN 16122. Double-leaf doors with central stile, lockable via profile cylinder lock.
Cabinet height without control unit and fan: 1950 mm

Version with operating voltage 230 V, 1-phase 16 A fusing, maximum electrical power per cabinet 3.5 kWh (max. 2 kWh per power strip)
Version with operating voltage 400 V, 3-phase 3 x 16 A fusing, maximum electrical power per cabinet 10.5 kWh (max. 3.5 kWh per power strip, for versions with 4 x power strips, the upper two power strips with 3.5 kWh each, the lower two with 1.75 kWh each)

Control unit of the SiS Li-Ion 90 Safe Pro:

– In case of smoke detection inside the cabinet, the power supply and the integrated ventilation are completely shut down
– In case of fire detection, an optical and acoustic alarm is triggered
– Optical status display informs about the current status of the cabinet (fire detection, ventilation unit, power strips)
– Includes potential-free contact for signal forwarding (e.g. to a control centre)
– Optional GSM module for remote monitoring and alarming available on request
– Model specially developed for the active and passive storage of lithium batteries, with GS certification according to test principle EK5 / AK4 22-01 and a real fire test of the cabinet equipped with lithium batteries carried out at MPA Dresden.

Functionality of the version with fire suppression system (aerosol extinguishing generator), with power-independent activation in case of fire or impermissible temperature increase from 180 °C:
The activation of the solid material contained in the extinguishing generator creates an aerosol of solid and gaseous particles. These spread throughout the cabinet in milliseconds, displacing oxygen, diluting flammable gases, and thereby initiating the extinguishing process. Thus, the aerosol intervenes in the chemical chain reaction of the fire process, among other things by displacing oxygen, and interrupts it. If the fire suppression system is not activated, the maintenance-free service life is 10 years.
