Dry Coolers

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.

Air Filtration Solutions

Failure to provide cost effective air intake protection to building or equipment fans, motors, heat exchangers and other process cooling systems adds up to a costly loss of productivity in safe and effective system operations. This is especially true of refrigeration and cooling application systems where heat transfer surfaces are dramatically impacted by buildup of dirt on the surface.

Cooling Towers

As debris is continuously drawn into the air intake of cooling towers, fouling the cooling water and increasing the need for chemicals to clean up sludge build-up, bacteria proliferation and bio-film on internal surfaces which lead to corrosion of the basin walls.
