1. Product Overview: Core module of Industrial Heat Exchange system setups

The FS-Elliott Compressor Oil Cooler (referred to as "FS-Elliott Oil Cooler") is an industrial-grade heat exchange device specifically built for centrifugal air compressors. Its primary function is to keep compressor oil temperature within safe operating limits through forced heat exchange, ensuring system setup stability.

1.1 Technical Evolution & Certification system setup

This cooler's technology originates from FS-Elliott's turbomachinery thermal management expertise dating back to its 1924 acquisition of KERR Turbine Company. The core design holds API672 certification and complies with ISO 8573-1 CLASS 0 oil-free air standards. Representative models like S0504002 incorporate patented spiral-grooved stainless steel tubes and external finned tubes through localized production at manufacturing partners like Wuxi Cooler Equipment Co., provide heat dissipation operational performance matching global top-tier brands.

1.2 system setup Architecture & Functional Modules

The cooler body consists of three-stage heat exchange units:

• Primary Cooling Module: Handles first-stage discharge high-temperature oil (up to 120°C)
• Secondary Cooling Module: Processes interstage cooling oil (85-95°C)
• Final Cooling Module: Manages third-stage discharge high-temperature oil (105-115°C)

Each module features straight-through tube design for gas-liquid separation, with self-cleaning filters capturing particles ≥0.5mm. The full-capacity auxiliary oil pump system setup keep 100% cooling capacity during main pump failures.

2. Technical Features & operational performance Data

2.1 High-overall efficiency Heat Exchange operational performance

The spiral-grooved stainless steel tube technology increases turbulent flow by 40%, while external finned tube structure (8:1 fin ratio) expands heat dissipation area by 65% within same volume. Field data shows 18% energy savings versus conventional coolers in 3,500CFM petrochemical use cases.

2.2 Reliability Engineering

• Bearing Protection: Dual-redundant temperature sensors activate cooling fans at 110°C and trigger compressor frequency reduction at 120°C
• Freeze Protection: Gradient diversion structure keep 30% cooling capacity at -20°C surrounding temperature
• Vibration Control: Tilting-pad thrust bearings limit vibration to ≤2.5mm/s (ISO 10816 Standard)

2.3 Maintenance Optimization

• Modular Maintenance: Horizontal split gearbox design minimizes service time by 40%
• Smart Diagnostics: R1000 control system setup monitors 12 parameters (oil temp, flow, pressure loss) with 98% fault prediction accuracy
Extended Cleaning Cycles: Straight-through tube design enables 8,000-hour cleaning intervals (3× longer than conventional coolers)
