Many cooling towers and fluid coolers last longer than the technology they were installed with.  Fluid-Tek offers efficiency upgrades for all manufacturers... BAC, Evapco & Marley. 

Fill Media
Older cooling towers were built with sheet fill that can sag with time.  This causes large gaps in the media preventing water from being dispersed over larger surface areas.  New high efficiency fill is more tightly packed and offers more heat exchange surface area to increase your  tower's efficiency.

Drift Eliminators
Over time, old drift eliminators can become clogged, and begin to restrict air flow.  In addition, older styles do not have large changes in direction leading to greater water loss.  New drift eliminators can reduce loss to 0.001% saving you money on water.

Variable Frequency Drives
Adding a VFD to your tower can greatly increase the energy efficiency of your fan motors leading to large savings in your energy costs. 

Spray Header System Upgrade
New spray header systems with upgraded nozzels can provide better spray patterns.  This leads to more even distribution of water on your fill or coil pack and in turn moore efficient heat rejection. 

Electronic Water Level Control
New EWLC systems can regulate water level with the accuracey of 1/8".  These new systems are not subject to false filling because of water turbulance and can be integrated into building automationf for more precise monitoring of your cooling equipment.
