SCSR1 – Supplemental Cooling System Service Units

The SCST1/SCSR1 family comprises Airbus-certified ground service units for filling, topping up, and draining elements of the Supplemental Cooling System. Manufactured by Test-Fuchs, the family covers the A350 ALL procedures and A380 SCS tasks per the referenced Tool/Equipment Bulletins. Operation uses external nitrogen supply and designated adapters to connect either the ground service panel or consumer units. Training packages are available to support safe, repeatable execution.

Keyfeatures

Airbus-Certified Coverage – Approved for A350 ALL SCS top-up/consumer-unit tasks and A380 SCS procedures per issued TEBs.

Procedure-Driven Operation – Supports accumulator top-up, CU/VCRU/chiller top-up and drainage, and defined centralized equipment tasks.

Adapter-Based Connectivity – Uses dedicated adapter kits to interface with the ground service panel or consumer units as required.

External Nitrogen Supply – Operates with an external N2 source to pressurize and execute test and service routines.

Service Training Available – Structured operator and maintenance training supports compliant, efficient field use.
