PCM Panel to cool battery cabinet in Telecom Shelter
Power Failure is very common in developing countries. Most BTS or Basic Telecom Shelters or Telecom Enclosures are equipped with electronic Equipments and Battery for emitting proper signal to the cell-phone users. Ac or Air conditioning is providec to keep it cool. When the power fails, the temperature inside the BTS or Basic Telecom Shelters start rising very rapidly due to heat generated by the equipments and also due to ambient conditions. Diesel Generators are provided to give back up. However they are largely depended on the alertness of the watchman cum operator at the site. The contractors often delay in sending diesel aggravating the problem. To minimize the dependence on generators, Back-up air-conditioning may be provided by phase change material. Latest™ 29T is used in India for giving back-up to Air-Conditions. 240kg of Latest™29T is generally used per BTS. 240kg*180 J/kg 43200 K Joules of backup. This is equal to 43200/3600 = 12 KWH of energy ( Theoretical Value is 188KJ/Kg of PCM giving back-up of 12.5 KWH).
Our PH-29 PCM panel to cool battery cabinet has been sucessfully applied in BTS telecom shelter. Our company supply PCM panels for CHINA UNICOM COMPANY.
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.
