Data Center Evaporative Cooling
Fire-Resistant Evaporative Cooling Media, Delivered on Data Center Time
Cooling media that performs to UL 900 standards — supplied nationally, in the volumes hyperscale and colocation operators need, and shipped in roughly 12 weeks while the rest of the industry quotes 40 weeks or more.
The Cooling Challenge in Modern Data Centers
Rising rack densities and relentless thermal loads have made cooling a front-line concern for every data center operator. Evaporative cooling remains one of the most energy- and water-efficient ways to reject that heat — but only when the media at the core of the system is engineered for the demands of a mission-critical facility.
The media you choose directly affects the two numbers your operations team watches most closely: Power Usage Effectiveness (PUE) and Water Usage Effectiveness (WUE). It determines how efficiently outside air is conditioned before it reaches your coils, how much fan energy your system consumes, how long the media lasts, and — critically — how your facility performs against fire-safety requirements.
Evaporative media is not a commodity. It’s an uptime and efficiency decision.
Standards & Certifications
We supply media that performs to the standards data center engineers screen for.
UL 900
Flame resistance for media installed in air-handling systems — the baseline screen for mission-critical airstreams.
ULC-S111, GREENGUARD & ISO
Additional references as applicable to the product line, including indoor air quality and quality management standards.
Certification Review
Guidance on media-level versus unit-level certification, so your team can evaluate every quote on equal footing.
Why Fire Resistance Is Non-Negotiable
In a facility built around continuous uptime, every component in the air path is a fire-safety consideration. Evaporative media sits directly in the airstream — which is why fire-resistant, UL 900-rated media is the baseline standard for serious data center applications, not an upgrade.
ACI supplies fire-resistant evaporative cooling media that performs to UL 900 standards, engineered for the airflow, water quality, and safety demands of mission-critical environments.
A word of caution for buyers: not every product marketed for evaporative cooling carries genuine media-level fire certification. Some carry only foreign or self-declared ratings, and others hold certifications that cover the cooler unit rather than the media itself. When you evaluate a quote, confirm the certification applies to the media — we’re happy to help you read the difference.
Performance That Protects Uptime and Efficiency
The right media does more than cool. It lowers your operating costs and holds its performance for years. Here’s what matters in a data center application:
Low pressure drop, lower PUE
Media engineered for minimal airflow resistance reduces the fan energy your system burns to move air — which flows straight through to a lower PUE ratio.
High, consistent saturation efficiency
Optimized flute geometry drives turbulent mixing of air and water for maximum heat and moisture transfer, delivering reliable cooling across a range of face velocities.
Carryover and drift control
Properly specified media and drift eliminators let your system run at high airflows without water entrainment — keeping downstream air clean and dry.
Durability and media memory
Quality media resists chlorine, biocides, and mechanical stress, recovers its shape under load, and rinses quickly to minimize maintenance downtime.
Water and scale management
Designed-in bleed-off behavior, algae resistance, and scale control extend service life and protect efficiency over the long run.
How ACI Serves the Market
Most media suppliers can talk specifications. What sets ACI apart is our ability to deliver — at national scale, at volume, and on the timeline a data center rollout actually runs on.
A 16-week lead time in a 40-week market. Supply chain delays have left many operators waiting the better part of a year for replacement media. ACI delivers in roughly 16 weeks. When a media change-out is on your critical path, that difference is measured in uptime.
National presence. Headquartered in the Pacific Northwest and operating coast to coast, ACI supports operators across every major data center corridor in the country — from the Southwest to the Mid-Atlantic and beyond.
Volume built for hyperscale. We’re structured to supply multi-site fleets and large-scale rollouts at the quantities and cadence hyperscale and colocation operators require — not one-off orders.
Experience that speaks your language. Our team brings deep experience in evaporative media supply, HVAC specification, and equivalency and submittal work. We’re a supply partner who understands the engineering and procurement process — not just a box shipper.
Replacement and retrofit fit. We supply media sized to fit your existing systems and cassette formats, so a switch to ACI doesn’t mean re-engineering your equipment.
Applications We Support
Let's Talk
Media availability shouldn’t be the thing that holds up your facility. If you’re planning a change-out, evaluating suppliers, or building resilience into your supply chain, ACI can help — with fire-resistant media that performs to UL 900 standards, delivered nationally in roughly 12 weeks.
