-ULTIPLIERS ARE BASED ON DRIFT OF  OF THE CIRCULATING WATER RATE

*Range = Difference between hot water temperature and cold water temperature.

EXAMPLE: 700 GPM circulating rate, 18°F cooling range. To maintain 4 concentrations, the required blowdown is 0.458% or .00458 times 700 GPM, which is 3.2 GPM.

If fluid cooler is operated at 4 concentrations, circulating water will contain four times as much dissolved solid as the makeup water, assuming none of the solids form scale or are otherwise removed from the system.

When water treatment chemicals are added, they should not be in-

Notetroduced into the circulating water system via the water collection basin of the cooling tower. Water velocities are lowest at that point, which results in inadequate mixing. An ideal location would be the redistribution basin above the coil.

Belt Tensioning

See Figure 1 and Figure 2 for MH Fluid Cooler models MHF702 thru MHF705. Loosen specified hardware located at the top and bottom of the motor support assembly before adjusting the jacking screws. Do not remove the hardware—it is required to support the motor. Tighten the hardware after adjustment. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions. Check tension frequently during the first 24-48 hours of run-in operation. Overtensioning shortens belt and bearing life. Keep belts free from foreign material which may cause slipping. Never apply belt dressing as this will damage the belt and cause early failure. A Dodge® V-Belt Tension Tester is an alternate method for tensioning V-belts. Check with you local belt supplier.
