WHERE THE BEST ARE BUILT
EVERY UNIT LEAVES TESTED
Fan arrays exercised across the modulation range on the floor
Controls sequences executed against live points — Delta DDC or 
Siemens PLC + HMI
Airflow, temp, humidity, pressure & leak monitoring verified end to end
Leakage & static proof tests on production units — witness testing available
Factory piping pressure-tested — one field connection, zero field leak-chasing
WHO BUILDS IT: THE FIFTY YEAR ANSWER
Precision air handling, built in Massachusetts since 1975 by a union workforce whose apprenticeship pipeline 
and retention are structural features of the product — the same hands build unit one and unit three hundred. 
In an era of pop-up CRAH suppliers scaling on renders, fifty years of shop discipline is a quality system no 
certificate substitutes for.
FIVE DEMANDS FOR ANY CASING CLAIM
Test method + pressure — on the unit size 
being purchase
Leakage proven positive AND negative
Thermal break standard, not an option code
Who runs the factory test — and the witness protocol
Controls sequence exercised before shipment
Guardian answers ship in the submittal package. If a competitor's answers require a meeting, that's an answer too.
SEE IT TESTED.
Witness testing available for owners and engineers of record.
