The AccuShield Advantage
Brentwood has long been the industry leader in the development of film fill designs, enhancements, and configurations that reduce the potential for fouling in cooling tower systems.

  foulingFouling (left) can be caused by excessive accumulation of biofilm on the fill walls. This biofilm acts as a “glue” to collect unwanted contaminants, which can lead to reduced cooling tower performance and/or the higher maintenance costs associated with keeping the systems clean and operating at peak efficiency.

The proprietary AccuShield anti-microbial compound that we permanently incorporate into our raw material further improves the long-term performance of our fills by slowing the growth of biofilm. Field tests have shown that AccuShield significantly reduced weight gain associated with biomass growth and fouling of film fills. In addition to field tests comprehensive lab testing was also performed to determine anti-microbial efficiency. Click here for a summary of our lab test method and results.

AccuShield technology is currently available on the following Brentwood Film Fills: VF19 PLUS, CF1900MA, OF21MA, and CF1200MA, and can be applied to any of our fills or drift eliminators upon request.

The Benefits of AccuShield Technology
• Significantly inhibits the growth of micro-organisms, which contribute to fouling
• Does not diminish the superior heat exchange performance of our fills
• Environmentally safe ... both EPA and FDA approved
• Unaffected by temperature extremes
• Not a simple coating, the anti-microbial benefits do not wear off
• AccuShield PVC meets CTI Material Standard 136
• Does not make PVC brittle or weaken the material in any other way


Recent field tests show that fill products without AccuShield gained 2.5 times more weight than products with AccuShield!
