Where Rittal sits in the stack
Rittal's placements in this catalog cover 6 parts, from layer 4 (servers, racks & integration) 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
- Enclosures — The rack cabinet frame itself — the enclosure that chassis and trays mount into, sold either as a standalone product or built in-house by the rack ODM.
- Rack PDUs — The power distribution units mounted in or beside a rack that meter and distribute power to individual devices, sitting between facility power and the rack's internal busbar or whips.
- 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.
- Rear-door heat exchangers — A heat exchanger mounted on the rear door of a server rack that cools exhaust air with chilled water or refrigerant before it leaves the rack, without cooling the chips directly.
- 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).
