Tropical · the honest version
Liquid cooling in the tropics — the real problem is where the heat goes.
Most of the world’s next data center capacity is being built in warm climates, where the physics is least forgiving. We build for those rooms — and we will not pretend the tropics are free.
Physics, not marketing
Three facts about heat in warm rooms
Capacity halves at 35 °C
An L2A loop rated at 25 °C room air delivers roughly half at 35 °C. Every L2A product on earth obeys this; not every vendor publishes it. We do.
The room still has to drink the heat
Tropical deployment does not remove the building AC — it borrows it. The room must extract ≥ 1.1 × IT load. The worksheet is public.
Outdoor rejection is mostly dead
At tropical wet-bulbs, dry coolers and free cooling collapse — mechanical refrigeration carries the load. "Independent of building AC" claims should be read accordingly.
Standards context
SS 726:2026 — the year the tropics got a standard
What it is
Singapore’s SS 726:2026 (Aug 2026) — the first national standard for liquid cooling in tropical climates. A milestone for the whole category: the tropics stopped being an edge case.
What it is not (for us, yet)
Its scope is data-center-internal, direct-to-chip, single-phase systems — our standalone edge cabinet sits outside that scope. We reference SS 726 as context, and we do not claim compliance. When a scope fits, we will test against it and publish the result.
The killer asset, in progress
35 °C full-load derating curve — measured, not modeled
No vendor in this category publishes a measured capacity-vs-room-temperature curve at full load. We are building the demo unit precisely so this page can carry one: 4-hour sustained 100% load at 35 °C, raw data, including any throttle events. Until then, this page shows the planning envelope derived from published L2A physics — and says so.
