SPX Cooling Technologies Inc. added an induced-draft counterflow cooler.
The Marley DT employs a closed-circuit design to keep the process fluid in a clean, closed loop. The process fluid is cooled by recirculating water that flows over the outside of heat transfer coils. As air induced through the cooler evaporates a small portion of the recirculating water, heat is rejected to the atmosphere.
According to SPX, the evaporative fluid cooler offers a high dry operation capacity in cold weather. The company also says the counterflow cooler has lower fan energy costs than forced-draft coolers. The design reduces system components compared to open tower and plate heat exchanger (PHE) systems.
