Three different versions can be built: Standard, Enhanced and Special Version. Main technical specifications are presented in Table 1.

The Standard version is based on the currently commissioned and tested first prototype MARTA-01. The prototype allows to reach the cooling power maximum 170W at -30°C (t_ambient 22°C) and 300 W at -25°C, (t_ambient 22°C), although some system components are currently being optimized and in next units it is expected to reach up to 200 W at -30°C, t_ambient 22°C).

The Enhanced version allows to reach the cooling power up to 300W at -30°C (t_ambient 22°C).

Both versions are currently being optimized and in the new MARTA units the cooling power is expected to be at the level of specified in Table 1.

The Special Version specification shows the maximum reachable cooling power with currently developed set up. It can be offered as an individually designed, custom made unit.
