Range Summary

The Narada Coolstar cabinet is designed to protect VRLA type lead acid batteries in telecommunication and photovoltaic energy storage applications against stressful ambient temperature conditions. The Coolstar energy efficient operation allows to significantly reduce equipment-cooling costs by targeting the thermal management efforts directly toward the 48V battery. It will minimize air conditioning energy costs of radio base stations by splitting the thermal management into natural ventilation and forced cooling. Coolstar is ideal for countries with hot or tropical climate and for any location where cooling/heating energy is at a premium and its consumption has to be minimized. The Coolstar cabinet has been designed on the basis of extensive CFD simulations of cell layout and airflow pattern.
