AC-120-2 Van Air Systems Air-Cooled Aftercoolers

AIR-COOLED AFTERCOOLERS FOR YOUR COMPRESSED AIR SYSTEM

In Van Air Systems AC series air-cooled aftercoolers, hot compressed air is introduced to the core as ambient air is drawn across it, leaving the exiting air cooler. AC series after-coolers are normally sized for a 15°F (or less) approach to ambient air. For example, a compressor discharges 250°F air and the aftercooler is located in 80°F ambient conditions. With a 15°F approach, the air exiting the aftercooler will be 95°F and saturated, and the moisture created by cooling from 250°F to 95°F will condense.

Features and Benefits:

• Galvanized steel cabinet
• Pressure drop less than 3 PSI at 80 to 125 PSIG

Applications:

• When compressed air temperatures exceed 100°F
• Installed before any type of compressed air dryer

Sizing Instructions:

• Determine inlet temperature to aftercooler.
• Determine desired outlet temperature. (Aftercooler outlet temperature = ambient temp. + approach)
• Determine needed approach. (Approach = desired outlet temp. - ambient temp.)
• Find flow (SCFM) under column of correct inlet and approach temperatures and read left for model number.

Standard Equipment:

• Ambient air flow: horizontal
• Floor or suspended mounting
• Galvanized steel cabinet
• Copper tube core with aluminum fins
• Heavy gauge aluminum fan with steel hub
• Steel fan guard with baked enamel finish
• Open vented motor
• NEMA frame: custom on 115-1-60 ODP models, NEMA 48 on others
• Thermal overload on 115-1-60 ODP models only
