OF21MA Overview

Brentwood’s AccuPac® Offset-Fluted Fills combine the low-fouling characteristics of vertical flow with the enhanced water distribution of cross-fluted designs. OF21MA’s design yields comparable thermal performance to CF1900 but with lower potential for fouling at a lower cost. It is generally used in field-erected and factory-assembled installations for applications where water contains a moderate level of total suspended solids.

Low Fouling Film Fill

Field-Erected Tower Retrofit at Chemical Plant

Brentwood worked with a chemical manufacturing company in Spain to replace their fill that was experiencing severe fouling. When the fills were removed from the tower, they weighed more than 10x the original weight of the clean fills! The Brentwood team recommended the use of OF21MA, along with an improved water distribution system (AccuSpray Nozzles) and upgraded drift eliminators (CF150MAx).
