Quiet Module Cooling Towers offer the most cooling power for your capital investment. Evaporative cooling allows you to reach near atmospheric wet bulb temperatures, and Quiet Module's compact, modular design enables you to expand your cooling system as your heat load increases.

Why treat water?

As the water in the cooling tower evaporates, most solid contaminants in the water do not evaporate. The concentration of these contaminants accumulates rapidly and will undermine the cooling capacity of the system. In addition, airborne impurities and biological contaminants are introduced into the recirculating water.

To control potential contaminants, a water treatment program must be employed. In most cases, use of a Pioneer Kleen-Water Filter and a simple bleed-off at the Pioneer filter may be adequate for control of scale and corrosion. However, biological contamination can be controlled only through the use of biocides, and such treatment should be initiated at system start-up and continued regularly thereafter.

For specific recommendations on water treatment, consult a local water treatment specialist.

Kleen-Water Filters

Water will evaporate from your cooling tower, but solid contaminants will not. Kleen-Water Filters are 99.0% efficient at removing solids down to 1 micron. The resulting clean water will allow your Quiet Module Cooling Tower to operate most efficiently while protecting your investment.

Kleen-Water Filters KW300 and larger include the Pioneer exclusive Back Saver feature to make element change painless.

Selection and Sizing the Proper Quiet Module Cooling Tower

Cooling Range = water temperature in (warm) - water temperature out (cool)

Approach Temperature = water temperature out - design wet bulb temperature

Locate maximum wet bulb temperature for your area - USA, Canada, Mexico
Determine cooling range and approach temperature - Selection Charts for 65, 70, 75, 80 Deg. F
Determine cooling tower selection factor based on your wet bulb temperature. Interpolate as necessary.
Using selection factor from step 3 and your desired rate of flow in GPM, determine proper Quiet Module Cooling Tower selection from Cooling Tower Capacities table. For safe sizing, oversize by 10 - 20%

Example: Size a cooling tower for

110 GPM flow

75 Deg. F wet bulb temperature

90 Deg. F inlet

82Deg. F outlet temperature.

With the above parameters and the accompanying charts we determine RKM40 by the following procedure

Wet bulb temperature = 75 Deg. F

Cooling range = 90 - 82 = 8 Deg. F; Approach temperature = 82 - 75 = 7 Deg. F

Selection factor = 5.3 (Selection Factor table, 75 Deg. F wet bulb)

From Cooling Tower Capacities table, Model RKM40 can handle 120 GPM at 5.0 selection factor or 136 GPM at 5.5 selection factor. At 5.3, it will handle approximately 130 GPM.
