1. Product Overview

This oil cooler is a direct OEM replacement heat exchanger specially engineered for all series of Sullair rotary screw air compressors, covering LS, S-energy, 900XH, E08, LT, ST and other mainstream models. It includes two mainstream types: aluminum plate-bar air-cooled oil cooler and shell & tube water-cooled oil cooler, fully matching original part numbers like 02250163-627, 88290022-959, 02250086-248, 02250151-493 etc.Alibaba.co...

As the core cooling component, it rapidly dissipates heat from high-temperature lubricating oil, stabilizes oil viscosity, avoids overheating shutdown, and protects airend, bearings and motor from thermal damage. Widely used in manufacturing, machinery, mining, food, chemical and other industrial compressed air stations.

2. Core Advantages & Key Features

✅ 100% OEM Dimension & Interface Compatibility

· Consistent mounting hole positions, oil inlet/outlet port size and pipeline layout with original Sullair coolers

· Plug-and-play installation, no pipeline modification, directly replace damaged original radiators

· Complete model database covering 5HP–4100kW Sullair compressors, thousands of part numbers in stock

✅ High-Efficiency Heat Dissipation Structure

· Air-cooled type: All-aluminum plate-bar brazed structure, dense fin array enlarges heat exchange area, fast heat exchange, stable oil temperature controlled below 85℃ under full load

· Water-cooled type: Thickened seamless copper tubes + 316L stainless steel shell, spiral flow design enhances turbulence, reduce oil temperature drop loss, adapt to high ambient temperature workshops

· Optimized internal flow channel reduces pressure loss, won’t increase compressor energy consumption

✅ Industrial-Grade Durable Materials

· Air-cooled core: High-purity aluminum alloy, vacuum brazing integrated molding, anti-leakage, anti-vibration

· Water-cooled core: T2 copper heat exchange tubes, laser welded shell, corrosion resistance for cooling water with impurities

· Surface anti-rust powder coating, resistant to dust, oil mist, high temperature and humid workshop environment

· Pressure resistance up to 12MPa, withstand long-term continuous heavy load operation

✅ Complete Overheating Protection for Compressor

· Effectively control lubricating oil temperature within safe range, prevent oil carbonization and deterioration

· Avoid high-temperature trip alarm, reduce unplanned downtime and production loss

· Extend service life of airend, oil filter, separator core and Sullube lubricant, cut maintenance cost

✅ Easy Maintenance & Low Operating Cost

· Split modular design, easy to disassemble, clean fins/tubes to remove dust and scale

· Standard spare part, far lower price than genuine Sullair original cooler, stable performance equal to OEM

· Long service life, no frequent replacement required

✅ Strict Factory Quality Control

· 100% air tightness pressure test before delivery to eliminate oil leakage risk

· Raw material inspection, semi-finished cooling efficiency test, finished product aging test

· Provide test video and dimensional drawing upon request
