02250178-717 Sullair Replacement Combination Cooler | Oil & Air Compressor Cooling Assembly

The 02250178-717 Sullair Replacement Combination Cooler is a critical thermal management component used in Sullair rotary screw air compressor systems that utilize a combined oil cooler and aftercooler design. This unit is responsible for removing heat from both the compressor oil circuit and the compressed air stream, ensuring stable operating temperatures throughout the system.

In rotary screw compressors, effective cooling is essential for long-term reliability. Compressor oil absorbs heat generated during compression and lubrication, while compressed air exits the air-end at elevated temperatures. A combination cooler efficiently manages both heat loads within a compact assembly, reducing system complexity while maintaining consistent thermal performance.

The 02250178-717 combination cooler is engineered as a direct replacement for Sullair compressor applications requiring this specific cooling configuration. It is well-suited for maintenance, rebuilds, and corrective service where cooling efficiency has been reduced due to fouling, corrosion, or internal restriction.

Functional Design and Performance

The 02250178-717 combination cooler functions as a dual-purpose heat exchanger within the compressor system. Hot oil exiting the air-end flows through one section of the cooler, where heat is transferred away before the oil returns to the lubrication circuit. At the same time, hot compressed air passes through the aftercooler section, reducing discharge temperature prior to downstream separation and treatment.

Maintaining proper oil temperature is essential for preserving lubricant viscosity, preventing varnish formation, and ensuring consistent sealing performance inside the air-end. Effective aftercooling reduces moisture load, improves air quality, and protects downstream components such as separators, dryers, and filters.

A properly functioning combination cooler helps stabilize operating temperatures during long run cycles, high ambient conditions, and heavy-duty applications commonly encountered in industrial environments.

Why Combination Coolers Are Critical

A failing or restricted combination cooler can cause elevated oil temperatures and excessive compressed air discharge temperatures. This leads to reduced lubrication effectiveness, increased moisture carryover, higher separator loading, and accelerated wear of internal compressor components.

Replacing a worn or damaged unit with the 02250178-717 Sullair Replacement Combination Cooler helps restore proper thermal balance within the compressor. Effective cooling improves overall system efficiency, supports longer oil life, and reduces the risk of unplanned downtime due to overheating-related failures.
