FLUID COOLING

Industrial BOL Series

AIR COOLED BOL

BRAZED ALUMINUM CONSTRUCTION

Features

Bar and Plate Brazed Aluminum Core

Rugged, lightweight, and compact

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 and BSPP

ports available

Customized units are available to

meet your speciﬁc performance

requirements

Additional capabilities for radiators,

charge-air-coolers, condensers, and

multi-circuit units

T-BAR core optional for high viscosity

oils or other highly fouling ﬂuids. *See

Selection Procedure Step 1 Determine Heat Load. Typical Rule of Thumb, -size cooler for 1/3 Metric Version of the input horsepower. Heat load may be expressed as either Horsepower or BTU/Hr or KW/°C. BTU/HR=HP x 2545 BTU/HR = KW x 1894.61 x E.T.D.(°F) °C Step 4 Select Model From Curves Enter the Performance Curves at the bottom with the GPM oil flow and proceed upward to the adjusted Heat Rejection from Step 3. Any Model or Curve on or above this point will meet these conditions.
