TRACI II

To support the particle physics community for their detector cooling development a multipurpose CO2 cooler called TRACI (Multipurpose Refrigeration Apparatus for CO2 Investigation) was developed. A new concept called I-2PACL was introduced to simplify the design and increase the temperature range from cold to room temperature.

TRACI is optimized for reduced costs and easy operation while keeping maximal flexibility.

TRACI version 2 offers operational temperature range of -35°C to +22°C with a cooling capacity up to 400 watt depending on the cooling temperature.

This portable unit guarantees stable operation with minimum control. At CERN three prototypes have been handed over to clients (CMS, Geneva University and Nikhef) and the operation of the system turned out to be easy and understandable by the non-expert users. Two units was equipped with a gear pumps and one with a membrane pump to ensure longer life time.
