AI clusters in existing air-cooled rooms
How it is used
Place the liquid-to-air cabinet alongside GPU racks to serve a local cooling loop without a facility-water connection.
Selection checkpoint
Check return-air paths, cabinet service clearance and total room cooling load.
Illustrative architecture, not a customer installation or an installation drawing.
Overview
- Liquid-to-air CDU: PG25 to the cold plates on the secondary side, heat rejected to room air by the built-in heat exchanger and fans, no facility water required
- 60 kW rated at 25 °C inlet air, 10 °C approach, 100 LPM secondary flow, variable 20–100%
- 1+1 redundant pumps with auto switchover, dual-feed ATS, leak detection, coolant quality monitoring, 25 µm filter, bypass online-replaceable filter and auto refill
- PID control of both airflow and coolant flow; Modbus RTU / TCP for BMS / DCIM
- In-row floor-standing, 600 × 1200 × 2000 mm, approx. 350 kg, IP55
- For retrofit rooms and small AI clusters without chilled water or cooling towers
Engineering fit
For retrofit rooms and small AI clusters without chilled water or cooling towers: only power and room air conditioning are needed to run direct-to-chip liquid cooling — no chilled water or cooling tower. 35 °C secondary supply is obtained from 25 °C room inlet air (10 °C approach); capacity derates with warmer room air per the selection table. Pairs with ToneCooling cold plates, manifolds and hose assemblies from the same factory.
- Retrofits without chilled water or cooling towers, a row of racks with 60 kW on liquid
- Phased builds of small AI clusters using room air conditioning for heat rejection
- Direct-to-chip cooling in edge / regional data centres
- Indoor alternative to an outdoor dry-cooler loop

Frequently asked questions
Under what conditions is the 60 kW rating valid?
Rated at 25 °C inlet air, 35 °C secondary supply and PG25. Usable capacity derates as room return air gets warmer; size the unit for the actual inlet air temperature.
Liquid-to-air or liquid-to-liquid CDU?
Choose liquid-to-air when the room has no chilled water or cooling tower, or when the water system must not be touched — room air conditioning removes the heat. Choose liquid-to-liquid when facility water exists and the load is large; it uses less energy per kW. Secondary connections are the same, so you can migrate later.
How much room cooling is needed?
The unit rejects the 60 kW cold-plate load into room air, so room CRAC/CRAH capacity must grow by 60 kW sensible, with hot/cold aisle airflow kept separate.
Which coolant on the secondary side?
Closed PG25 (25 % propylene glycol / water) loop with 25 µm filtration, cleaned at the factory and pre-filled on request.
Which protocols are supported?
Modbus RTU and Modbus TCP/IP are standard; the register map ships with the unit. Ask about other protocols when requesting a quote.
Lead time?
Standard units ship in 6–8 weeks; every unit ships with pressure, leak and flow-resistance test records.
