WHERE THE BEST ARE BUILT
COILS BUILT TO THE LOAD, 
NOT TO THE CATALOG
Across every Guardian platform - CRAH, CRAC, & GFA - the coil bank is sized to your entering 
condition, not pulled off a shelf. Chilled-water or DX, the selection is engineered, the build is 
factory-piped, and the pressure test happens before it ever leaves Massachusetts.

Guardian CRAH and Guardian FA run multi-row chilled-water coils — V-bank or flat, 4 to 6 rows, flanged and 
glycol-capable — sized in factory coil software to your entering water temperature, supply-air setpoint, and 
sensible load. Guardian CRAC runs direct-expansion refrigerant coils, engineered for A2L-compatible systems 
as the industry completes its refrigerant transition, with circuiting matched to compressor staging and 
superheat control for the room it's protecting. Every coil — CW or DX — is manifolded to a single supply and 
return inside the casing, so the field sees one connection, not a coil farm.
Selected, not assumed. Coil capacity, face velocity, and water/refrigerant-side pressure drop are issued 
per project from factory selection software — the same certified-selection discipline applied to fans and 
casings elsewhere in the Guardian line.

SOURCED FOR THE SCHEDULE
Coil capacity is reserved across multiple OEM partners — no single-source exposure on the component that 
gates a CRAH build. Stainless casing options, washdown-rated drain pans, and factory hydrostatic testing are 
standard wherever the spec calls for them.
