BATTERY COOLER

Stulz range of air conditioners fulfill the requirements of battery banks cooling :

EVE04 air conditioner for installation inside the cabinet

BATTERY COOLER

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 .

Batteries in telecom cabinets function as a backup in case of power failure and are essential to assure the continuity of the data flow.

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.

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.
