Page 14: Freeze Protection
Marley Fluid Cooler Fluid Cooler Coil When the ambient temperature falls below 0°C, heat loss from the coil can be substantial even without recirculating water flowing over the coil. The process fluid, without an applied heat load, may be prone to freezing. -
Page 15: Water Quality
Marley Fluid Cooler The MC Fluid Cooler can be a very effective air washer. Atmospheric dust able to pass through the relatively small louver openings will enter the recirculating water system. Increased concentrations can intensify systems maintenance by clogging screens and strainers—and smaller particulates can coat system heat transfer surfaces. -
