GUARDIAN CUSTOM CRAH
THE HIGH END OF THE MARKET, ENGINEERED 
TO YOUR ENVELOPE.
The Guardian Custom CRAH is engineered around your cooling requirements, space envelope, 
and operating strategy, delivering scalable performance for high-density data centers, hyperscale 
campuses, and AI infrastructure. From multi-coil V-bank configurations and high-efficiency IE5 
fan walls to vertical upflow, downflow, or side-discharge designs, every unit is tailored to optimize 
airflow, redundancy, serviceability, and energy efficiency. Whether supporting a single white space 
or scaling across multi-megawatt halls, the Guardian Custom CRAH provides a flexible, 
application-specific solution designed to meet the demands of today's most advanced 
computing environments.

WHAT “ENGINEERED TO SPEC” ACTUALLY COVERS:
Footprint, height and section split to your white space 
and rigging path
V-bank coil geometry tuned to EWT, approach and water-
side P
Fan wall count and redundancy logic (N+1 to N+2) per your
concurrency model
Discharge orientation, plenum height, and top/side 
duct collars
Delta Controls platform, points list and BAS protocol to 
the owner's standard
Dual power / ATS, humidification, electric heat, filtration 
to MERV high-efficiency
Stainless drain pans, washdown construction, seismic 
and wind-load packages
Factory witness testing — airflow, leakage, controls
