Commercial / Industrial Cooling Tower Side Stream Filters
Cooling towers are excellent air scrubbers. High volumes of air pass through the tower subjecting components to airborne contaminants. Concentrated make up water can also contribute to build up of contaminants on the cooling tower distribution and fill areas which eventually flake off and become suspended in the recirculating water. Even a marginal improvement in the efficiency of evaporative cooling equipment, heat exchangers and chillers can offer owners significant savings over the lifespan of the cooling systems. Improving the water quality in the cooling loop is a simple, cost effective method of realizing efficiency gains.
Many contaminants cannot be seen by the visable eye. Collectively they can lead to system inefficiencies, increased micro biological growth and excessive corrosion. Suspended solids result in water with high turbidity which can foul heat exchange surfaces. These silt like contaminants also end up in low flow areas such as the cooling tower basin. This provides a place for bacteria to attach and multiply which results in high potential for under deposit corrosion and microbiologically induced corrosion (MIC). Under high flow conditions the suspended solids can also be abrasive and cause excessive wear of pump seals and valves and erosion of pipes.
Excalibur’s Cooling Tower Filters are set up to filter objects larger than either 1 micron or 5 microns in diameter.
