MERLIN is a thermal carrier that has been approved for flight in Middeck and EXPRESS Rack accomodations. MERLIN is a rear-breathing Middeck Locker (MDL) replacement incubator that provides a thermally controlled environment for scientific experiments in the International Space Station (ISS) EXPRESS Rack, or the now retired Space Shuttle. Also used to support Crew Galley Operations.

• Advanced Single Middeck Locker Incubator / Freezer (Heat exchanger designed for both rear-air or water loop heat rejection)
• Previous interfaces include Shuttle Middeck and SPACEHAB
• Capable with interfacing with Commerical Orbital Transportation System (COTS) vehicles
• 30+ pound payload with 16.5" (X) by 10.188" (Y) by 6.69" (Z) experiment volume (CG at the center of the experiment volume)
• Payload volume for both conduction or convection cooling modes
• Provides thermal control from -20^oC to 48.5^oC
• Fully programmable temperature control including ramps and recovery modes can be configured / executed via the display, EXPRESS RIC, and remotely from the ground (both commanding and file uplink)
• System temperature sensor readings (8)
• Experiment temp. sensor readings (up to 12)
• PID control temperature (derived)
• A/D sensor readings (up to 10)
• Digital I/O readings (8)
• Last command status information
• Error reporting/acknowledgement information
• Data storage utilization status
• Thermal control data
