Product catalog summary
Overview: The P-Bar Series Industrial AOL is an air-cooled fluid cooling system designed for hydraulic or compressor oil cooling. It features a brazed aluminum construction, offering high performance and industrial durability. The system is ideal for converting water-cooled equipment to air-cooled, reducing water and sewer costs and eliminating corrosion issues associated with water-cooled units.
Key Features:
  • Large oil flow capacity and high performance.
  • Compact all-aluminum core assembly with a brazed aluminum bar and plate core.
  • Vertical air flow suitable for heat recovery.
  • State-of-the-art heat transfer technology with optional SAE ports and marine corrosion control coatings.
  • Detachable legs for flexibility.
Materials:
  • Legs: Steel with baked enamel finish.
  • Shroud: Steel.
  • Core: Brazed Aluminum Bar and Plate.
  • Fan: Aluminum Hub, Plastic Blades.
  • Motor: TEFC.
Ratings:
  • Maximum operating pressure: 250 psi (17 BAR).
  • Maximum operating temperature: 300°F (150°C).
Ordering Information: Models are available in various sizes (400 to 3500) with options for connection type (NPT or SAE), motor requirements (No Motor, Single Phase, Three Phase, etc.), and noise levels (Standard or Low Noise).
Performance and Maintenance:
  • Performance curves are based on a 100°F (55.56°C) Entering Temperature Difference.
  • Oil pressure drop coding ranges from 5 PSI to 30 PSI.
  • Regular maintenance includes cleaning fins with compressed air and using chlorinated solvents for internal cleaning.
Selection Procedure: Detailed dimensions and weights are provided for each model, along with fan and motor specifications, including CFM, horsepower, voltage, and sound levels.
Additional Notes:
  • A three-way thermostatic valve is recommended for bypassing cold oil during startup.
  • Coolers should not operate in ambient temperatures below 35°F (1°C).
  • Outdoor operation requires weather protection.
Performance Curves: Graphs illustrate horsepower removed in cooler at 100°F ETD and heat rejection in KW/°C, with options for low noise models.
