The Marley Difference – Fan Cylinders
The fan cylinder does far more than protect operating personnel from a rotating fan. It is a vital link in the chain of critical components that contribute to the overall efficiency of the cooling tower. When correctly designed, manufactured and applied, it assures that the fan will be capable of moving the maximum amount of air through the tower at the minimum required horsepower.
The Marley Difference – Geareducer Drive
Marley Geareducers have been manufactured in a variety of sizes and load ratings appropriate for cooling tower applications since the 1930s. We began doing so because geared speed reducers suitable for cooling tower service were not commercially available. Since that time, we have produced well over 100,000 units, and have established an unparalleled record of performance reliability.
Corrosion Protection for Cooling Towers
The forces of corrosion (as the term is being used in this paper) are those elements or compounds whose natural tendency is to chemically or electrolytically react with a metal, given the opportunity and a proper set of circumstances.
Cooling Towers and Salt Water
For cooling tower service, any circulating water with more than 750 parts per million chloride expressed as NaCl is generally considered as salt water. However, the effects of chlorides will be much less severe at 750 ppm than they will at higher concentrations.
Cooling Tower Energy and Its Management
Because of the fuel shortages which began to manifest themselves in the early 1970s, the cost of energy began an asymptotic rise. The level of attention to energy savings has risen as a part of a broader green approach to design, including carbon footprint.
Purposes and Types of Fill
The relationship between water surface exposure and heat transfer rate is intrinsic to all types of cooling towers, regardless of the type of water distribution system utilized. The more water surface exposed to given flow of air, the greater will be the rate of heat transfer.
HTK Pump Heat Trace Engineering Data
The Marley HTK heat trace kit is provided for fluid cooler recirculation pumps to protect the frame of the spray pump in regions where freezing conditions are expected.
