BTMS – Tramway cooling system a system for cooling the glycoled water for batteries

The BTMS has been developed in order to make circulate and to assure a temperature of 20°C for the glycoled water for the batteries of the tramway. At the time of its design SDEEC has considered particularly a compact device of easy access and reliable.
