Air-cooled CDU project
Containerised compute at a desert site with no facility water plant. Air-cooled CDUs reject straight to ambient at design temperatures where a dry cooler alone would not hold the loop.
Ten reference sites across five continents — grid substations, swapping stations, telecom shelters and utility-scale storage, running through Nordic winters and Gulf summers alike.

Containerised compute at a desert site with no facility water plant. Air-cooled CDUs reject straight to ambient at design temperatures where a dry cooler alone would not hold the loop.

Cabinet-level storage under a shelter canopy. Door-mounted coolers sized so the pack delta stays inside the BMS window through a full summer duty cycle.

A winter site where the problem inverts: the cooling equipment has to bring the pack up to operating temperature as often as it takes heat out. Heat-pump mode, not just refrigeration.

Packs cycle in and out all day, each arriving warm from the road. Cooling has to absorb a stochastic load rather than a steady one, in a cabinet the public walks past.

Substation cabinets specified for a maintenance interval measured in years. Sealed air-to-air exchangers with no compressor, so there is nothing in the cooling path to fail between visits.

Distribution equipment in a subtropical climate — high humidity, heavy rain, and condensation risk that matters more than peak ambient.

Street-level cabinets where acoustic limits are as binding as the thermal spec, and the unit has to disappear into a residential streetscape.

Tower-base cabinets on a hybrid power supply. 48 VDC units run straight off the battery bus, so cooling does not force the generator to start.

Walk-in shelters at high ambient with unreliable grid. Split and package BTS units rated T3 to 55 °C, with automatic restart when input voltage comes back into range.

An OEM component inside a diagnostics platform: 2–10 °C coolant at ±1.0 °C to several points from one pump, with the set point configurable over RS-485.
