Permatron's PreVent® air intake filters provide the first line of defense in preventing debris from entering dry cooler systems. Cottonwood seeds, leaves, pollen, paper debris, industrial waste, nesting birds, construction debris and insects are continuously drawn into air intakes costing thousands of dollars and man hours on equipment repair downtime and maintenance. Facilities' utilize dry cooler units to take the heat load out of buildings and keep vast computer and other electronic systems running cool. With air intake air flow rates of 20,000+, airborne debris frequently gets pulled into the unit, coating fins and coils. Without frequent cleaning, this causes heat build-up, higher discharge pressure and amp draws. Reduced air flow causes equipment to run for longer cycle times, at reduced capacity, decreased life expectancy, increased filter changes and escalating power costs.
Frequent cleaning is especially hard on this type of unit because it sits on the ground, elevated on 2-1/2' legs, with the high velocity air intake located beneath the unit. Along with the fresh air, contaminates are also sucked up vertically into the fins and coils, clogging the unit. With barely shoulder width space to work between the system and the concrete, cleaning is extremely difficult, messy and labor intensive. This type of application can easily be protected with a "skirted" PreVent filter that includes a botton pocket with weighted PVC piping to hold the filter straight down to the concrete.
- All Air Intakes Are Not the Same
Typical equipment maintenance includes having to clean the delicate fins and coils with time consuming hand brushing and messy corrosive chemicals that can damage the system components and the environment over time. This is especially problematic when the fins and coils are located in hard to reach places ...
- Jackson National Life Dry Cooler Screens
Every piece of equipment, large or small, stationary or mobile, indoors or outdoors, needs preventative maintenance. Dirt, debris and grease are continually coating and insulating equipment coils, electronic systems, motors, fins and other components that fall in the path of the equipment's air intake. Airflow obstructions of any kind are a costly expense. The Jackson National Life facility utilizes five rooftop mounted Liebert glycol dry cooler units to take the heat load out of the building and keep the vast computer systems running cool. These units were requiring frequent cleaning, which took up a huge block of man hours and equipment downtime.
