Introduction
The Ingersoll Rand 47556402001 47552954001 Water-Cooled Preventive Maintenance Kit with Modification combination covers the temperature-control portion of the modified 8,000-hour major-service program for the R90–110 I platform. 47556402001 is the overall water-cooled maintenance package with modification, while 47552954001 identifies the temperature-control valve maintenance component.
Temperature management is a critical function in an oil-injected rotary screw compressor. Compressor lubricant performs both lubrication and heat-transfer duties, so controlling its temperature helps maintain suitable viscosity and stable operating conditions.
The 47552954001 reference is specifically identified in the parts catalog as a temperature-control valve maintenance kit and is associated with the R90–160 family. This distinguishes it from a complete water cooler, water-cooler seal kit, hose kit, or standalone temperature sensor.
The relationship between the requested references is direct. The R90–110 I service table lists 47556402001 as the 8,000-hour water-cooled package with MOD and specifies one 47552954001 temperature-control valve kit. The same package includes 23429822, 23424922, 23497001, 23545841, 23531577, 47553881001, 47555464001, and 39218193.
This makes 47556402001 a comprehensive major-service package rather than a single thermal-control repair. Filtration, separation, pressure control, inlet control, cooling-system sealing, temperature control, and motor lubrication are addressed together.
The MOD designation is important for maintenance planning. The modification changes selected components within the service package, notably the inlet-valve service kit, but it does not change every recurring maintenance component. The temperature-control kit remains 47552954001 in the published R90–110 I configuration.
Temperature-control valve deterioration can occur through contamination, seal aging, mechanical wear, repeated thermal cycling, or changes in valve operating characteristics. Scheduled maintenance provides an opportunity to renew applicable service components before unstable thermal behavior affects compressor operation.
Abnormal lubricant temperature should not automatically be attributed to the temperature-control valve. Cooler fouling, flow restrictions, incorrect lubricant level, sensor faults, ambient conditions, and control-system problems can create similar symptoms. Diagnosis should therefore consider the entire thermal-management system.
During service, technicians should inspect the valve assembly, sensing/control elements, seals, connections, and associated fluid passages according to the applicable Ingersoll Rand procedure. Any contamination or mechanical damage should be corrected before returning the compressor to service.
The exact internal contents of 47552954001 should not be inferred solely from its product title. A service kit can contain valve internals, seals, springs, or other configuration-specific items. The current compressor-specific bill of materials should determine the actual contents and quantities.
Application verification remains important because 47552954001 is used across multiple R90–160 configurations. A compressor revision or thermal-control arrangement can affect the required service components even within the same nominal frame family.
For maintenance planning, 47556402001 should be distinguished from the standard water-cooled 8,000-hour package 47555465001. Both use the same 47552954001 temperature-control kit in the documented R90–110 I configuration, but the MOD package uses a different inlet-valve service reference.
For purchasing teams, retaining both references provides useful traceability: 47556402001 identifies the modified 8,000-hour water-cooled maintenance event, while 47552954001 identifies the temperature-control valve service requirement.
A proper replacement process should verify the compressor model, serial number, cooling configuration, valve arrangement, and current service instructions. After installation, the compressor should be monitored to confirm appropriate lubricant-temperature behavior across startup, loading, unloading, and normal operation.
The current technical sources do not provide sufficiently reliable engineering values for the valve's exact dimensions, temperature setpoint, spring characteristics, internal kit contents, package dimensions, or weight. These values are therefore intentionally not estimated.
For industrial compressor operators and maintenance professionals, 47556402001 and 47552954001 provide a clear reference for temperature-control service within the modified 8,000-hour water-cooled R90–110 I maintenance program. Correct configuration matching and careful valve servicing can help maintain stable lubricant temperature and dependable compressor operation.
