Cooling tower tank design.

Cooling tower pumps are notorious for caviation and operating problems based on a bad sump design. 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. Design and operation 2005 2018 trane a business of ingersoll rand. The majority of our cooling tower sump tanks are sandblasted interior to a near white followed by 7 to 11 mils dft of epoxy.

Cooling tower equipment louver motor pump tank. Tank cover manufactured from stainless steel and supplied in sections for ease of removal and access covers are optional. Tanks are structurally supported around top and sides as required. All tanks have baffled compartments if required.

Introduction a cooling tower is a heat rejection device which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Remote sump tanks are often installed indoors in a heated space to prevent freezing of the recirculating water during cold weather operation. 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. 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.

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. The majority of our cooling tower sump tanks are sandblasted interior to a near white followed by 7 to 11 mils dft of epoxy. A trane engineers newsletter live cooling towers and condenser water systems. Cooling towers may either use the evaporation of water to.

If the tank has a flat bottom the exterior bottom of the tank should have a. C approach to wet bulb temperature. If additional head pressure is a possibility the additional head pressure should be calculated and built into the design of the tank. D mass flowrate of water circulation rate e air velocity through tower or individual tower cell.

Piping condenser cooling tower losses and valves. It must also provide the energy head necessary to raise water from a low to a higher static head level. Remote sump tanks can be added to cooling tower closed circuit cooling tower or evaporative condenser systems.
