BOL Series

Quick Overview

FLUID COOLING HEAT EXCHANGER WITH PRESSURE BYPASS

Fan Flow Rate: 667 to 14000 cfm (18.9 to 396.44 cmm)
Max Operating Pressure: 250 PSI (17 bar)
Max Operating Temperature: 300 °F (150 °C)

The rugged, lightweight and compact BOL Series provides outstanding heat dissipation for extreme heat loads.  Available with AC or hydraulic fan motors, all feature proven brazed aluminum P-BAR™ plate and bar core technology engineered with an aggressive turbulator that produces ultra-high heat transfer.  Available with two bypass relief options — a factory installed pressure bypass (P-BAR core) or an internal temperature controlled bypass (T-BAR™ core).

 

Features

  • Bar and Plate Brazed Aluminum Core
  • Provides the best heat transfer per given envelope size while minimizing pressure drop
  • Air-side fin design minimizes fouling and static pressure ensuring long-term, reliable performance
  • Welded fittings/ports and manifolds ensure structural integrity
  • Standard SAE ports – NPT & BSPP available
  • Customized units are available to meet your OE specific performance requirements
  • T-BAR core optional for high viscosity oils or other highly fouling fluids.
