Model 1400 SCR systems — the bridges, phase cells, blowers, and control modules that keep them running, plus sourcing and rebuild support.
Independent sourcing, not an authorized distributor. Ross Hill, NOV, and other manufacturer names are used for reference only. We supply new-surplus, used-tested, and reconditioned equipment with condition disclosed before sale, and we fabricate enclosures, panels, and assemblies in house. Complete-system requirements are sourced and quoted case by case — tell us the scope and we will tell you honestly what we can put together.
The Ross Hill Model 1400 is one of the most widely deployed SCR systems on diesel-electric land and offshore rigs, and a large number are still turning. Parts support from original channels is long gone, which puts these systems squarely in the surplus and reconditioned market.

This is not a complete parts list. If it lives in a Model 1400, send the number.
Model 1400 and Model 1500 phase cells are not interchangeable. Confirm the model generation before ordering cells or bay hardware. We verify against what you actually have rather than against what the paperwork says.
The blower is not an accessory. SCR bays are thermally limited, and a degraded blower shows up as nuisance trips and shortened device life long before anything obviously fails. If a Model 1400 is tripping under sustained load, check airflow and filters before condemning devices.
Condition always disclosed before sale. Photos on request. Same-day response on most requests. Complete-system requirements are quoted case by case.
Send the part number or a photo of the bay.
