Introduction
The Ingersoll Rand 47588564001 / 47552954001 Temperature Control Valve Maintenance Kit combines a scheduled preventive-maintenance reference with a dedicated service kit for the compressor's thermal-control system.
47588564001 is documented as an 8,000-hour preventive maintenance kit for air-cooled compressors. Ingersoll Rand parts catalogs list it alongside other scheduled-maintenance references, including 2,000-hour and 4,000-hour kits and separate water-cooled maintenance kits.
The independently documented 47552954001 is identified as a temperature control valve maintenance kit for R90–160, IR90–160, and IE R90–160 configurations. This places the component within the lubricant-temperature regulation system of larger R-series rotary screw compressors.
Temperature control is an important part of lubricated screw-compressor operation. Compressor oil performs several functions simultaneously: it lubricates bearings and other moving components, removes heat, provides sealing within the compression process, and helps protect internal surfaces.
The temperature-control valve regulates the path taken by the lubricant as it circulates through the compressor. Depending on oil temperature and system conditions, the valve controls how much lubricant is directed through the cooler and how much is allowed to bypass it.
This regulation helps the compressor avoid operating with lubricant that is either excessively cold or excessively hot. Both conditions can adversely affect compressor performance.
When lubricant temperature is too low, moisture can be more difficult to keep in vapor form, increasing the potential for condensation-related problems. When lubricant temperature becomes excessive, viscosity and lubricant degradation can become concerns, while thermal stress on the oil circuit may increase.
The temperature-control valve therefore works as part of a larger thermal-management system that includes the compressor oil circuit and oil cooler. Proper valve operation helps maintain the intended balance between cooling and oil circulation.
47552954001 should be distinguished from other valve service references in the same R90–160 family. For example, 47553881001 is cataloged as an intake valve service kit 8K, while 47553880001 is also listed as an intake-valve service kit for R90–160 configurations. These parts perform different functions and should not be substituted for the temperature-control valve kit.
During maintenance, technicians should inspect the temperature-control valve for signs of sticking, contamination, seal deterioration, or abnormal oil-flow behavior. The associated oil cooler and connecting passages should also be checked because a valve problem can sometimes be confused with a restricted cooler or another oil-circuit fault.
Correct assembly is important because improper installation or damaged sealing components can produce oil leakage or abnormal flow through the temperature-control circuit.
The complete physical dimensions and weight of 47552954001 could not be reliably verified from the available technical documentation. Since it is a multi-component maintenance kit, package dimensions and weight can also vary according to configuration and packaging.
The supplied pair is treated as one product listing as requested. Public records independently establish 47588564001 as the 8,000-hour air-cooled preventive-maintenance kit and 47552954001 as the temperature-control valve maintenance kit. The available documentation does not independently establish that 47552954001 is the complete bill of materials contained in 47588564001.
