Cross Flow Cooling Towers
Manufactured By:

RSS series cross flow cooling towers feature non-corrosive FRP (Fiberglass Reinforced Polyester) construction which will provide years of maintenance free operation. The modular design allows for easy installation. Tower cells can be mounted side by side with common piping to handle most any capacity requirement. With over 20 years of Fiberglass Cooling Tower experience, RSD cooling towers are sure to provide you the performance and reliability you demand.

FRP (Fiberglass Reinforced Polyester) Construction: All RSS towers feature FRP Fan Stack, Casing and Water Basins. The FRP panels are both corrosion and chemical resistant. The gelcoat finish includes UV inhibitors to protect the tower from the damaging effects of the sun.

STD-201 Certification Purpose:
"This standard sets forth a program whereby the Cooling Technology Institute will certify that all models of a line of water cooling towers offered for sale by a specific manufacturer will perform thermally in accordance with the manufacturer's published ratings. . . "

RSD Crossflow Cooling Towers

FRP (Fiberglass Reinforced Polyester) Construction: All RSS towers feature FRP Fan Stack, Casing and Water Basins. The FRP panels are both corrosion and chemical resistant. The gelcoat finish includes UV inhibitors to protect the tower from the damaging effects of the sun.

Motors: All motors are UL recognized TEFC construction, and specially designed for our application. The motors are VFD rated, with frequency drive control panels available as a factory option.

Fan Blades: All tower fans feature cast aluminum construction and provide a large volume of stable air at low noise levels. The fan pitch is adjustable in the field to optimize the performance and to account for variance in static pressure.

Tower Fill: Our tower fill is constructed of thermoformed PVC to ensure uniform density across the entire deck. The PVC material is resistant to both chemical and biological attack. The sheets are UV protected and meet the CTI STD-136 for rigid PVC. (Limited to 115F continuous duty.) Premium fill with higher temperature ratings is also available upon request.

Inlet Louvers: Our PVC inlet louvers are designed to allow maximum inlet air while limiting unwanted splash from the tower fill. The PVC material is UV protected and is resistant to both chemical and biological attack.

Support Structure: The tower support structure and motor frame are constructed of shot dipped galvanized steel. Optional Stainless Steel components are available upon request.

Ladders and Safety Railing: All RSS towers are equipped with OSHA standard ladders and safety railings to allow safe and easy access during inspection and maintenance. These are available in standard hot dipped galvanized or optional Stainless Steel.

Water Distribution System: Water is distributed across the fill deck though a FRP distribution pan. The pan is easily accessible for inspection and service. There are no moving parts or spray nozzles which makes the system virtually maintenance free. FRP basin covers are provided to keep the tower clean.

Refer to the Hydraulic Load Demand

Welding Tip Coolers 84/min(avg.) 1 10
Dry Cleaning Machines 5,000 btu/lb cap. 3 gpm/ton 10.00

Whenever possible calculate actual values as follows:

Load in btu/hr = (range x gpm) x 500
Cooling Range = (btu load/gpm)/500
GPM = (btu load/range)/500
Cooling Range = (inlet to tower - desired outlet)

bhp = Brakehorse power
gpm = Gallons per minute
500 = 8.33lb/gal x 60 minutes
1 ton = 15,000 btu/hr
