Climate Control Systems (CCS) and Life Support Systems (LSS) for the new T-90 tank and BMP-2. Similar systems have been installed in the Israeli Merkava tanks. The Indian army is interested in Climate Control Systems (CCS) due to the excessive heat levels experienced in AFVs, which severely impact the reliability of electronic equipment. LSS are utilizing an air conditioning system, which feeds clean, cool air into the fighting compartment. The CCS is suitable for applications where limited power is available, as it utilizes “spot cooling” of selected electronic equipment. Similar concepts are also applied with micro-cooling for the crew, by the use of collective NBC protection and individual cooling suits.
