Don't Overheat.We Made Sure.
Precision HVAC for colocation, hyperscale, and enterprise data centers. From emergency retrofits to ground-up builds — Coolant crews are on-site before the thermal alarm becomes a ticket.

CRAH Unit Failure — Zone 4B
Failure Analysis
A single CRAH bearing failure at 2:17 AM cascaded across six rack rows. Inlet temps hit 97°F within 22 minutes. Emergency throttling kept the cluster alive — but 14 nodes hard-rebooted before the crew arrived.
Blanking panels missing across 40% of rack units, …
Hot Aisle Bypass — Colo Wing C
Failure Analysis
Missing blanking panels across a legacy colo wing allowed exhaust air to loop back into intake. Cold aisle crept from 68°F to 88°F over six weeks. PUE degraded from 1.42 to 1.79. The client's power bill told the story before the thermal map did.
Cooling plant at 94% capacity during peak load, no…
Capacity Redline — Summer Peak
Failure Analysis
A hyperscale campus director's Q3 buildout plan hit a wall: the cooling plant was already at 94% load. Adding 200 kW of new compute without infrastructure upgrades would have triggered a site-wide thermal event within 90 days of go-live.
Refrigerant leak in primary glycol loop, 15% capac…
Glycol Leak — Primary Loop
Failure Analysis
A pinhole leak in a glycol fitting went undetected for 11 days. The loop lost 15% of its cooling capacity gradually — thermal drift was masked by ambient monitoring gaps. Detection came only when a rack cluster started thermal throttling.
The Turn

solved looks like.
Every installation below started as one of those incident cards. Same metrics. Different outcome. The delta is the crew you call first.
Same metric.

Each card maps directly to a failure mode from the section above. CFD overlays and commissioning reports available on request.
CFD validated: 100% cold aisle isolation achieved
Emergency Retrofit
In-Row Precision Cooling — Phoenix Colo
Installation Report
Six Schneider Electric in-row units seated between high-density GPU clusters. CFD modeling validated cold aisle isolation before a single tile was cut. Inlet temps dropped from 97°F to 64°F within 6 hours of commissioning.
Airflow path verified: zero bypass recirculation
Planned Expansion
Raised-Floor Retrofit — Las Vegas Hyperscale
Installation Report
Full blanking panel remediation across 18 rows, supplemental CRAH units on 24-inch raised floor, and perforated tile rebalancing. Cold aisle stabilized at 65°F. PUE recovered from 1.79 to 1.38 — a $340,000 annual power saving.
N+1 redundancy: full load failover validated
New Build
Chiller Plant Expansion — Austin Campus
Installation Report
Two 800-ton centrifugal chillers added to primary plant, variable-speed pumping loop installed, and cooling tower capacity doubled. Load factor dropped from 94% to 51%, creating full headroom for the Q3 compute expansion.
Leak detection: <0.5% variance threshold set
Emergency Retrofit
Hot Aisle Containment — Denver Enterprise
Installation Report
Glycol loop repaired, containment doors and ceiling panels installed across 8 rows, leak detection sensors deployed at every fitting. System returned to full cooling capacity within 14 hours. Monitoring now catches sub-1% flow variance.

From the field.
Coolant's crew was on-site within 36 hours of our CRAH failure. They didn't just fix the unit — they rerouted our entire airflow path and left us with a CFD model we still use for capacity planning.
Marcus Okonkwo
Facility Director, Vantage Data Centers — Phoenix
We brought Coolant in for a six-month new build. They finished in four and a half. The commissioning data they handed us was cleaner than anything our in-house team has produced.
Jennifer Callahan
VP Infrastructure, Corelink Colocation — Austin
Our Q3 expansion was contingent on solving a capacity problem nobody else would touch. Coolant sized the chiller plant, pulled the permits, and had us commissioned two weeks ahead of schedule.
