Ingersoll Rand 47555465001 47552954001 Water-Cooled Preventive Maintenance Kit

Introduction

The Ingersoll Rand 47555465001 47552954001 Water-Cooled Preventive Maintenance Kit combination covers the temperature-control portion of the 8,000-hour major-service program for compatible R90–110 I compressors. 47555465001 is identified as the 8,000-hour water-cooled preventive-maintenance package, while 47552954001 is identified as a temperature-control valve maintenance kit used in the R90–160 family.

Temperature management is an important part of rotary screw compressor operation. The compressor lubricant performs both lubrication and heat-transfer functions, so controlling its temperature helps maintain suitable operating conditions across different load levels and ambient conditions.

The 47552954001 reference is specifically described in current parts-service data as a temperature control valve maintenance kit or temperature-sensing valve maintenance kit. The description distinguishes it from a complete cooling-system kit and from individual hoses, seals, filters, or valve components.

The broader 47555465001 package is a major service event rather than a single-component replacement. Its published R90–110 I configuration includes the air filter 23429822, coolant filter 23424922, pre-filter 23497001, separator element 23545841, minimum-pressure valve kit 23531577, temperature-control kit 47552954001, inlet-valve service kit, water-cooler seal kit, and motor grease.

This integrated approach is useful during major preventive maintenance because several components affecting compressor thermal performance can be inspected or renewed at the same time. Temperature control should not be considered independently of the cooler, lubricant circuit, valve operation, and associated seals.

A malfunctioning temperature-control valve can contribute to operating temperatures that are too high or too low. Either condition can affect compressor behavior and lubricant performance. However, abnormal temperature should not automatically be attributed to the valve; cooler condition, flow restrictions, sensor faults, lubricant condition, ambient temperature, and control-system problems can produce similar symptoms.

During service, technicians should inspect the valve assembly, sensing components, seals, connections, and associated cooling passages. Contamination and deposits that interfere with valve movement or heat-transfer performance should be addressed according to the applicable Ingersoll Rand procedure.

The exact internal contents of 47552954001 should not be inferred solely from its title. Service kits can contain seals, valve internals, springs, or other configuration-specific components, and the current bill of materials should determine the contents for the actual machine.

Application verification is particularly important because 47552954001 appears in service information for multiple R90–160 configurations. A kit intended for one compressor revision or cooling arrangement should not be assumed to fit another simply because both machines are within the same nominal horsepower range.

For maintenance planning, the distinction between 47555465001 and 47552954001 is useful: the first identifies the scheduled major-service package, while the second identifies the temperature-control subsystem service requirement.

For procurement teams, retaining both references in the compressor service record can improve traceability and reduce confusion between the temperature-control kit and other 8,000-hour components such as the inlet-valve kit or water-cooler seal kit.

The 47552954001 number is also listed alongside other Ingersoll Rand service references in supplier databases, reinforcing its role as a dedicated temperature-control maintenance reference rather than a generic spare part.

Exact valve dimensions, temperature setpoints, spring characteristics, internal kit contents, package dimensions, kit weight, and complete application coverage were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.

For industrial compressor operators and service professionals, 47555465001 and 47552954001 provide a clear reference for temperature-control maintenance within the 8,000-hour water-cooled R90–110 service program. Correct configuration matching and proper valve servicing can help maintain stable lubricant temperature and dependable compressor operation.

Technical Specifications
