DIRECT DRIVE FLUID COOLERS: FN
Overview
Our engineers have carefully selected and matched components on the FN fluid coolers to provide excellent performance, long
service life and a wide range of performance selections. The FN fluid coolers are specifically engineered for outdoor installations.
FN fluid coolers are available in a wide range of sizes. In addition, the FN series feature multiple motor options to provide reduced
sound and energy consumption options. Each model is available with several circuit options to ensure the exact fluid cooler
for your requirements. FN fluid coolers are designed to reduce the installation and maintenance costs. Each unit is completely
assembled and tested at the factory.
FNH, FNL and FNQ Standard Features
n BOHN fluid coils incorporate the latest advancements in coil technology to provide
maximum capacity.
n Coils available in 1/2” for high heat transfer or 5/8” tube diameters for low pressure
drop applications (see model availability).
n All FN models feature design elements to help eliminate leaks at the tube sheet. All
1/2” models incorporate the Floating Tube coil design.
n All 5/8” models incorporate bushing plates allowing for coil expansion and contraction.
Coils feature a 5 yr. warranty against fluid leaks caused by tube contact at end and
center coil support sheets.
n Coils are fabricated with corrugated aluminum fins (10 FPI) with staggered copper
tubes for optimum heat transfer. All coils are
pressure tested prior to shipment.
n Galvanized steel housing for corrosion protection.
n Fully baffled fan sections provide structural strength and prevent fan wind milling in the off cycle.
n Direct drive motors in 1140 (FNH), 830 (FNL) or 540 RPM (FNQ).
n Energy efficient, three phase fan motors with ball bearings and internal overload protection.
ServiceEase™ Motor Mount System
