Extreme Heat Can Inhibit Fiber Optic Cable Installation and Damage Fiber Optic Cable and Duct. When Cable Blowing, Air is Compressed and Heat is Generated. For Example, Air that Enters a Compressor at 100°F (37°C) Exits the Compressor at 350°F (176°C). At this Temperature, Fiber Optic Cable Jacket and Duct Softening can Occur. Heat Problems Can Also Occur if the Duct Run is Exposed to Direct Sunlight. The Condux Compressed Air Cooler Can Help Prevent Heat Damage to Fiber Optic Cable and Duct During Cable Blowing Operations.

The Condux Compressed Air Cooler, Cools Compressed Air from a Maximum Temperature of 350°F (176°C), to within 20°F (11°C) of the Ambient Temperature. For Example, If the Ambient Temperature is 100°F (37°), Air from the Air Compressor Enters the Air Cooler at 350°F (176°F). Cooling the Air Reduces the Chances of heat Damage to the Cable and Duct.

The Condux Compressed Air Cooler also Removes Moisture From the Air. Water from Humid Air Can Dilute Cable Blowing Lubricant and Collect in the Duct Run.

Use of the Condux Compressed Air Cooler is Recommended when Ambient Air Temperatures Reach 90°F (32°C) or More and/or the Duct is Exposed to Direct Sunlight.

How Much Air?

Pressure
During Pressurized Blowing Applications, as the Duct Size Increases and the Pressure Remains Constant, the Pulling Force Increases Geometrically. When Used Properly, the Amount of Pulling Force Placed on the Cable by the Condux Fiber Optic Cable Blower Cable Carrier Remains Below the Cable's Recommended Maximum Pulling Tension for Two Reasons. First, the Blower is Designed for Use with A Maximum 2 Inch (51 mm) Diameter Duct. Second, the Maximum Amount of Pressure Applied by the Blower During Installation Never Exceeds 150 psi (10.3 bar).

At the Pressure, with a 2 Inch (51 mm) Duct, a Maximum Pulling Tension at 482 lbs (2,145 N) Can be Generated on the Cable by the Cable Carrier. This is Well Below the 600 lbs (2,668 N) Recommended Maximum Pulling Tension for Most Cable Types. Ducts Smaller then 2 Inches (51 mm) or Pressures Lower than 150 psi (10.3 bar).

Flow
Duct Size also Determines the Compressor Flow Needed for Proper Installation. For Innerducts from 1 to 1-1/4 Inches (25-31 mm) in Diameter, a 175-275 SCFM (5-8 cu meters/min) Compressor is Recommended. For Innerducts from 1-1/2 to 2 Inches (28-51 mm) in Diameter, a 275-375 SCFM (8-11 cu meters/min) Compressor is Recommended. Compressor Flow Should be Doubled if the Distance Exceeds 6,00-8,000 feet (1.8-2.4 km).
