AB  - In the scope of the High Luminosity program of the Large Hadron Collider at CERN, the ATLAS and CMS experiments are advancing the preparation for the production, commissioning and installation of their new environment-friendly low-temperature detector cooling systems for their new trackers, calorimeters and timing layers. The selected secondary ¿on-detector¿ CO₂ pumped loop concept is the evolution of the successful 2PACL technique allowing for oil-free, stable, low-temperature control. The new systems are of unprecedented scale and largely more complex for both mechanics and controls than installations of today. This paper will present a general system overview and the technical progress achieved by the EP-DT group at CERN over the last few years in the development and construction of the future CO₂ cooling systems for silicon detectors at AT-LAS and CMS. We will describe in detail a homogenised infrastructure and control system architecture which spreads between surface and underground and has been applied to both experiments. Systems will be equipped with multi-level redundancy (electrical, mechanical and control) described in detail herein. We will discuss numerous controls-related challenges faced during the prototyping program and solutions deployed that spread from electrical design organization to instrumentation selection and PLC programming. We will finally present how we plan to organise commissioning and system performance check out.
