BOL Series Air Cooled Heat Exchanger

The Thermal Transfer series BOL Air Cooled Heat Exchanger is a rugged, lightweight and provides outstanding heat dissipation for extreme heat loads.  Available with AC or hydraulic fan motors, all feature the 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)

The BOL series heat exchanger is exception for use with oil, mineral oil, oil/water emulsions, or water/glycol
