Smaller crossflow towers offers Perforated stats having surface and splash area equivalent to the timber section 1 ½ X ½” (highly used fill in wooden towers) giving an enhanced thermal performance. The diamond shaped perforations made out on the stats reduce the pressure drop considerably. The tower efficiency can be increased by up to 15% by offering a higher airflow for the same power and configuration or by reducing the power required to maintain the same airflow.

Older cross flow timber towers as well as some of the inefficiently designed newer once use rectangular timber slats for application as fill media. The rectangular timber slats provide very little in terms of enhanced surface area for the air and water to mix. Super plast has designed perforated slats to replace existing rectangular timber slats.

The efficient design of the SPC perforated slats cause the water droplets spread over the solid surface and perforated holes. The flowing water is held on the holes due to surface tension and forms a thin film. The water film formed over these rectangular holes has very low surface tension at its corners and thus a tendency to capture frequently. During this process of rupturing the water film is broken into small globules, thus providing maximum heat transfer.

These slats provide performance improvement over wooden rectangular fills and other perforated slats with round holes, over which, water film has relatively higher surface tension.

Better heat transfer rations due to the formation and quick rupture of water film on diamond shaped Perforations
Pack volume is reduced to 10% to that of timber slats
Increases the void volume in the tower, resulting in higher capacity
Economical and durable compared to wooden slats
No channeling of water
Perforations provide a considerable reduction in pressure drop resulting in lower power consumption and /or increase in air flow
