BATTERY COOLER
BATTERY COOLER
Batteries in telecom cabinets function as a backup in case of power
failure and are essential to assure the continuity
of the data flow.
The best working temperature range
for battery banks is around 25 °C; is
very important to maintain the correct
temperature for the battery banks, in
fact, if the cabinet temperature goes
too higher the batteries life could be
shortened .
In Telecom cabinets and electronic facility rooms are, however,
present some devices which can work at higher temperature.
In this case the best solution is to separate the cabinet in two areas with
a different temperature control: one area dedicated to the batteries
and maintained the correct temperature and protect from dust , wind,
etc.; whereas the other area can be maintened at higher temperature.
In this way is possible to significantly reduce the energy consumption
for cooling.
Stulz range of air conditioners fulfill the requirements of battery
banks cooling :
EVE04
EVO04
air conditioner
for installation
inside the cabinet
air conditioner
for installation
outside the cabinet
Furthermore, both EVE and EVO units
are powered at 48VDC, like the
battery banks, so there’s no need
to have an inverter to transform the
Direct current in Alternate Current,
with considerably energy costs
savings.
