A large containerboard mill located in southern Mississippi needed to replace the cooling tower used for its electrical rooms, along with an additional tower that supplied comfort air to the building’s offices. Both were the classic metal-clad design framed with wood and were beginning to disintegrate.

After reviewing its cooling tower replacement priorities, the company — a producer of tissue, pulp, paper and packaging — decided to use engineered plastic cooling towers made out of high density polyethylene (HDPE). Unaffected by weather, caustic conditions and water treatment chemicals, HDPE cooling towers do not rust or corrode.

The mill’s facility engineers elected the TM Series from to install Delta Cooling, Roxbury Township, N.J. The induced-draft, counter-flow design is available in single-unit capacities from 250 to 2,500 cooling tons. A modular design allows the cooling towers to be assembled in multiple configurations of up to six units.
