Where Johnson Controls sits in the stack
Johnson Controls's placements in this catalog cover 10 parts, from layer 5 (liquid cooling (it-side: chip to cdu)) to layer 9 (building shell, site & construction). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Coolant distribution units — The unit that separates the IT-side (technology) coolant loop from the facility water loop, exchanging heat between them and pumping and filtering the technology-side flow — sized from in-rack and in-row units up to multi-megawatt facility-class units.
- Chillers & compressors — Chillers use a vapor-compression or absorption cycle, built around a compressor, to produce chilled water for the facility's cooling loop.
- CRAH / CRAC / fan walls / in-row units — CRAH, CRAC, fan-wall, and in-row units circulate conditioned air across IT equipment in air-cooled halls, using either facility chilled water (CRAH) or an internal refrigerant circuit (CRAC).
- Air handling, economizers, filtration — Air-handling units, outside-air economizers, and filtration equipment that condition and clean the air supplied to air-cooled data center halls.
- Valves and actuators — Valves and actuators that modulate and isolate flow within the facility water loop, including zone-isolation valves that take a section offline without stopping the whole loop.
- and 5 more in the table above.
