OPTI-PAC 2100 Plus OF Media
Opti-Pac 2100 Plus OF is a higher performing, low-fouling film fill media with vertically offset flutes manufactured from rigid corrugated PVC sheets for counterflow cooling tower heat-transfer applications. The fill modules are solvent-welded for maximum strength and are resistant to UV, rot, fungus, organic / inorganic acids, alkalis, and chemicals normally found in cooling tower water.

Modules are fabricated in 12", 24" and 48” depths, 12” to 24” widths, and in lengths up to 12’-0” in 2’ increments. Sheet spacing is 21mm and minimum heat transfer area (wetted surface) is 45 ft2/ft3. Standard PVC sheet mil thicknesses are 10 and 15 mil (after forming). Weight per cubic foot is approximately 1.6 lbs/ft3 for 10-mil packs and approximately 2.4 lbs/ft3 for 15-mil. Custom dimension modules and mil thicknesses are available upon request.
