Splash Fills

Perforated V-Bar is the most extensively used product in the industry. SUPER PLASTcan supply the stainless steel or FRP coated wire mesh as well as the other components that are needed for the entire splash bar system.

The water droplets spread over the solid surface and perforated holes of the splash bar. 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 rupture frequently. During this process of rupturing the water film is broken into small globules, thus providing maximum heat transfer.

Features and Advantages

• Diamond shaped perforations are recommended as they offer the ideal surface tension to rupture the water droplets.
• The top edge of the V-bar is reinforced so as it offer bending and load strength..
• Ensuring a minimum thickness of 1.5mm and a maximum distance of 600mm between adjacent bars will help reduce the possibilities of sagging.
• Compact locking of the V-Bar on the grid using a V-Bar clip (as depicted in the picture) will also ensure a sturdy fill structure.
• The overhang of the V-bar of the last grid should be restricted to 150mm.
• Algae resistant and Fire retardant

Technical Specifications

The OPTI GRID is one of the more established splash fills used in counterflow cooling towers. Due of the small surface area exposed to the falling water, OPTI GRID is a nonfouling fill, and has been used extensively in industries and plants where fill fouling had been extensive.

The grids are supported in uniformly spaced tiers throughout the cell width and length on stainless steel wires hung from supports installed under the water distribution system, and on polypropylene supports specifically designed to secure the grid to the wires. Each grid in each tier is secured to all adjacent grids by special clips that tie the entire fill assembly securely in place.

Features and Advantages

• The configuration of the OPTI GRID allows water droplets to fall across multiple layers of horizontal strips.
• Even as the water droplets bounce off from one layer to another the thin strips cause shearing action on them causing them to break into smaller droplets.
• The construction OPTI GRID is configured to maximize the probability of the water droplets continuously encountering these thin horizontal strips on their way down to the basin. This is evident from the fact that alternate layers of the installed OPTI GRID have these strips displaced from the layers above rather than all in a single line. This results in a far more efficient working of the splashing principle.

Technical Specifications

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 with upto 20% increase in efficiency.

The water droplets spread over the solid surface and perforated holes of the splash bar. 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 rupture frequently. During this process of rupturing the water film is broken into small globules, thus providing maximum heat transfer.

Features and Advantages

• Better heat transfer ratios 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,

Technical Specifications

While the latter gives 20% higher efficiency than the former, the configuration of the COOLBar can accord a further performance increase of 20% within the same tower. Based on the same principle as that of other splash bars, 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 pentagonal shaped holes has very low surface tension at its corners and thus a tendency to rupture frequently. During this process of rupturing the water film is broken into small globules, thus providing maximum heat transfer.

Features and Advantages

• The low height of the COOLBar plays a significant role in causing lower pressure drop especially in case of installations where the fill is installed perpendicular to the airflow.
• The larger base allows for much higher splash area compared to other small splash bars.
• The quantum of splash fills needed for the same cooling can be reduced or with the same configuration the tower can be subject to higher duty load by replacing other polymer splash bars with the COOLBar
• The COOLBar has been provided with notches on its arms for more secure fitment onto the wire mesh.
