What’s inside

• VRT Vertiv: Pure-play on rack-level thermal; bought PurgeRite and ThermoKey to own end-to-end heat rejection
• ECL Ecolab: Acquiring CoolIT Systems pushes it straight into next-gen AI liquid cooling
• SMCI Supermicro: DLC-2 captures up to 98% of rack heat and cuts data-center power by up to 40%
• TT Trane Technologies: Efficient heating and cooling; management frames the built environment as the core climate load
• CARR Carrier: Cooling and building systems scaled to a hotter, more AC-dependent world
• JCI Johnson Controls: Building HVAC and controls; backing new cooling tech through strategic venture investment
• LII Lennox International: Direct leverage to replacement AC demand as heat waves lengthen cooling seasons
• ETN Eaton: Electrical equipment and power management sold into the same data-center build as cooling
• GEV GE Vernova: Generation and grid equipment for demand that cooling keeps pushing higher
• PWR Quanta Services: Grid construction and infrastructure services needed before any cooled load can be served
• HON Honeywell: Industrial automation and sensing that make building and facility cooling measurably efficient

Why it could work

Hotter buildings and denser computing need better cooling. The basket combines direct participants and broader suppliers.

What could break it

Adoption could disappoint, competition could weaken margins, or high valuations could already price in the trend. Some holdings are broad, indirect proxies.
