Data centers & mission-critical
Data centers, labs, emergency operations centers and defense sites never stop cooling. Cognituv keeps the coils clean and watches the equipment that keeps you online.

What’s at stake
Biofilm on cooling coils raises airside pressure drop and reduces heat transfer, so fans work harder for the same cooling. ASHRAE-funded field research (RP-1738) measured both effects with and without UV-C.
Mechanical coil cleaning takes units offline, and the fouling comes back.
Cooling towers and piping grow biofilm that drives corrosion and Legionella risk. ASHRAE Standard 188 sets out how to manage it.
Bearing wear, filter loading and drifting temperatures need to show up as alerts, not outages.

What we look at first, the systems we usually find, the codes and standards to check and where we’d start. Codes and standards are listed for reference: a listing isn’t a compliance finding, and doesn’t mean any product, Cognituv’s included, is certified to one.
Computing halls with the cooling and electrical plant that supports them, run by one enterprise or shared by many tenants.
Includes: Enterprise data center · Colocation data center
Distributed computing rooms and modules, often remote, with little or no staff on site.
Includes: Standalone edge site · Modular or containerized installation · Computing room inside another building
Emergency operations centers, secure facilities and modular buildings that have to stay up, often on their own network rules.
Includes: Emergency operations center · Defense or secure facility · Modular facility

Coil pressure drop, supply temperatures and equipment vibration set the baseline.
On-coil UV-C and water treatment where the data shows fouling, installed while the room stays live.
The same sensors keep reporting, so changes in pressure drop and temperature are measured, not assumed.
Where we work: Data centers and server rooms, Research labs and clean rooms, Emergency operations centers, Defense and secure facilities, Telecom hubs and Trading floors.
Codes and standards
The list comes from Cognituv’s facility and code library, reviewed September 2026. Publication isn’t adoption: whether a document applies, and which edition, depends on your jurisdiction, its amendments and your project, and the authority having jurisdiction decides. A listing isn’t a compliance finding for your facility, and doesn’t mean any product, Cognituv’s included, is certified to it.
