Cooling Tower Tank Design

The required cooling tower design and size will be a function of following values.

Cooling tower tank design.

C approach to wet bulb temperature. Cooling towers may either use the evaporation of water to. Tanks are structurally supported around top and sides as required. The majority of our cooling tower sump tanks are sandblasted interior to a near white followed by 7 to 11 mils dft of epoxy.

If the tank has a flat bottom the exterior bottom of the tank should have a commercial blast followed by a coal tar epoxy to protect from the condensation. B web bulb temperature. Remote sump tanks can be added to cooling tower closed circuit cooling tower or evaporative condenser systems. A trane engineers newsletter live cooling towers and condenser water systems.

The majority of our cooling tower sump tanks are sandblasted interior to a near white followed by 7 to 11 mils dft of epoxy. D mass flowrate of water circulation rate e air velocity through tower or individual tower cell. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near. Cooling tower pumps are notorious for caviation and operating problems based on a bad sump design.

It must also provide the energy head necessary to raise water from a low to a higher static head level. For the tower piping circuit the pump must overcome the piping flow friction loss. All tanks have baffled compartments if required. Cooling tower equipment louver motor pump tank.

I suggest that you review the sump design suggestions conatined in the pump handbook karrassic et al and the information in the hydraulic institute standards cooling tower pumps require an additional npsh margin above the npsh required. Remote sump tanks are often installed indoors in a heated space to prevent freezing of the recirculating water during cold weather operation. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access covers are optional.

If additional head pressure is a possibility the additional head pressure should be calculated and built into the design of the tank. If the tank has a flat bottom the exterior bottom of the tank should have a. Piping condenser cooling tower losses and valves.
