Our BD250GH compressors offer an outstanding reliable and efficient cooling solution for batteries and cabinets in telecommunication base stations. Reliabilitiy of telecom network depends on life of battery bank. Life of battery reduces half by increase in 9°C (from 25°C). Average power failure is 9-10 hours a day, hence batteries run out of temperature envelope. AC compressors are not running during power failures since they are dependet on AC power supply. Hence, Quality and Reliability are the most important key buying factors and customer would like to be independent of AC power.
