COMMERCIAL / INDUSTRIAL COOLING TOWER SIDE STREAM FILTER SYSTEMS

WHY DO COOLING TOWERS REQUIRE FILTRATION?

WHY DO COOLING TOWERS REQUIRE FILTRATION?

Cooling towers are excellent air scrubbers. High volumes of air pass through the tower subjecting components to airborn 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 are not visible to the naked 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.

BENEFITS OF COOLING TOWER FILTRATON

• Reduced energy consumption via clean heat exchange surfaces
• Reduced treatment chemical costs and enhanced performance
• Enhanced biological growth control reducing the risk of health related problems
• Increased cooling tower life expectancy from continuous cleaning
• A mechanical system provides continuous maintenance while a maintenance crew can only provide interval
   maintenance; continuous maintenance ensures continuous operation

 

FEATURES OF THE EXCALIBUR SIDE STREAM COOLING TOWER FILTERFEATURES OF THE EXCALIBUR SIDE STREAM COOLING TOWER FILTER

• Each side stream filter has its own pump to maintain cooling system capacity
• Excalibur Side Stream Filter media is designed to remove small particles: 1 micron or more.
• Excalibur control valves provide multiple backwash initiation options, including pressure differential, water flow volume or time
• Excalibur regeneration provides backwash and fast rinse using separate source municipal or filtered water
• Ability to install multiple filter vessel system with one controller to stage backwash and fast rinse so not to affect water flow required for other equipment
• Excalibur side stream filter has controller with a built-in motor control package
• Stores historical operating data: the number of back washes, peak flow rate since day of install, current flow rate and total daily flow up to 63 days, which is useful in determining how many times system volume has turned over, along with many other operational parameters
• Excalibur Side Stream Filter provide pressure gauges for separate source regenerations, pump discharge and post filter
• Excalibur Simplex Side Stream Filters do not require an additional pump for separate source backwash and fast rinse; they utilize the inline pump system that is part of the side stream filter
