The CCR 100 SMS is a consequent extension of the SCR 100 XT to a closed system in which the KISS style was realized. In the case of the CCR 100 SMS, the SCR 100 XT runs with a 2 litres diluent cylinder and a 2 litres oxygen cylinder. The diluent flows over the bypass and the oxygen flows over the constant flow (KISS style).
It is also possible to extend the gas stock by 2x2 litres cylinders.
