A fluid cooler model incorporates finned coils to expand thermal performance and permit dry operation during a broader range of ambient temperatures. Marley DT can more effectively reject heat without evaporating water at ambient temperatures up to 20 degrees higher than with bare tube coils, which helps reduce costs associated with water usage, water treatment and pump energy.

In colder weather conditions, the fluid cooler offers higher dry operation capacity than fill/coil hybrid coolers. Manufactured by SPX Cooling Technologies, it delivers lower fan energy costs compared to forced-draft coolers and reduces system components compared to combination open tower and plate heat exchanger (PHE) systems.
