"MA" (Mechanical Assembly) Technology
Brentwood MA (Mechanical Assembly) Technology

Brentwood's patented "MA Technology" allows fill or drift eliminator packs to be permanently assembled, without glue, by crimping the male/female attachment tabs molded into the individual sheets.

This innovative attachment process produces packs that are exceptionally strong, environmentally-friendly, less expensive than glued, and easily, efficiently assembled on-site.

How "MA" works
To make an "MA" pack, first assemble two sheets into a pair using the male/female attachment tabs that align with and nest into the adjoining sheet's tabs. Then crimp the attachment tabs using a Brentwood MAssembler.

Finally, using the same "MA" pressure-sealed attachment technique, edge-bond the assembled pair to another pair and then repeat the process until a pack in the desired width is assembled.

"MA" is strong
Each mechanically-assembled pair of MA sheets is, in effect, a small pack having a very high beam strength proportional to its depth. When edge-bonded into a full-size pack, the result is a pack that can support weight 10 times greater than the average fill load (fill plus water).

"MA" is environmentally-friendly
In the last 20 years, U.S. industry has made great strides in reducing pollution. With the help of the EPA, the current focus in American industry is on reducing air pollution, including VOCs (Volatile Organic Compounds) found in oil-based paints, auto fuels, and most petroleum products. The EPA reports that 20% of the VOCs discharged into the air are from industrial production applications.

Glued cooling tower fill packs contain VOCs. At Brentwood, we have been working for the last two decades to reduce the amount of VOCs we use, and to find other assembly methods to eliminate gluing altogether. MA (Mechanical Assembly) is the answer! This method of assembly uses no glue, produces an exceptionally strong pack, is less expensive than glued packs, and successfully addresses both the Clean Air Act and OSHA’s Hazard Communication regulation.

"MA" is economical
• Since there are no glue costs, those savings are passed on to the customer.
• Save even more on shipping costs (Flat sheets are far less expensive to ship than assembled packs)

"MA" is easily and efficiently assembled on-site
• As fast to assemble as gluing
• No EPA, OSHA, or fire concerns
• No “double-handling” of packs. Packs can go right into the tower after assembly
• "MAssembler" equipment (below) is simple to set up on-site, easy to use, and is rented on a per project basis to save costs. Shipping size is approximately 190 ft3 (5.4 m3), including Feed and Take-off Tables.
