PCM panel back-up for Base telecom shelter battery cooling facilities
PH-29 for outdoor use and PH-26 for indoor use
1. PCM panels absorb heat when melting and release heat when freezing
2. The PCM panel is like PH-26, that is freezes at 26C. Therefore during night time with cooler ambient temperature(say 10C) the PCM will freeze. During the day time as temperature rises (say 35C) the PCM will melt absorbing heat within the cabinet.
Overall the life of the batteries is increased by limiting temperature fluctuation.
Currently our company has PH-26 PCM panel for indoor batter cabinet and PH-29 PCM panel for outdoor battery cabinet.

Advantages and Disadvantages of PCM panel between our company and other foreign countries
1. PCM latent heat: Our PCM has much larger latent heat than many other suppliers
2. Almost every PCM panel production process (PCM panel HDPE panel body production, PCM filling) is runned by ourselves, initial cost is largely lowerd. So, compared with other PCM panel suppliers, our PCM panel has much more obvious competitive price.
