Opti-Pac 1900 Crossflow (XF/IL/IDE)

Opti-Pac 1900 XF/IL/DE (XF = cross cut / IL = integrated louver / IDE - integrated drift eliminator) is a cross-fluted film fill media manufactured from rigid PVC sheets for cross-flow cooling tower heat-transfer applications. The media is fabricated from corrugated PVC sheets conforming to CTI STD-136 that are solvent-welded for maximum strength and are resistant to UV, rot, fungus, organic / inorganic acids, alkalis, and chemicals normally found in cooling tower waters.

The principle of operation of cooling tower fill is to put as much water surface area in contact with as much air as possible, for the longest amount of time possible. Film fills allow the water to form thin flowing sheets to expose as much water surface area as possible to the interacting flow. 

Cooling tower sheet fills or media, come in many different forms and “micro-structures,” each having unique characteristics to fit various applications. Film fills are selected for direct replacement, performance enhancement, and water condition compatibility. Each fill has performance characteristics that allow selections to be made for various heat loads, flow rates, water quality, and horsepower combinations.

Film fill designs include:

Modules are fabricated in 12" and 24" depths, 12" to 24" widths, and in lengths up to 12'-0". Sheet spacing is 0.75" (19mm). Heat-transfer area (wetted surface) is 48 ft2 per ft3. Standard PVC sheet mil thicknesses are 10 and 15 mil (after forming). Weight per cubic foot is approximately 1.8 lb/ft3 for 10-mil and approximately 2.6 lb/ft3 for 15-mil. Custom dimension modules and mil thicknesses are available upon request.
