HRFG SERIES FEATURES
An FRP laminate is 5 times lighter than its equivalent of the same size and thickness made from steel. You will also find that when compared to a steel laminate of the same mechanical resistance, the FRP laminate is about half as heavy.
The low coefficient of expansion of the FRP material makes it highly resistant to wide variations of temperature and humidity without showing any deformation. These properties allow REYMSA Cooling Towers to withstand many different types of environments.
Only for appearance purposes, such as dusting or waxing.
It is very easy to perform minor repair work on the fiberglass. Materials are available all across the country, and the fixing process is as easy as grinding the surface, applying the Polyester Resin, which is in the form of a liquid, to a layer of fiberglass cloth and applying the resin again. Finally, wait until the resin is dried.

FIBERGLASS REINFORCED POLYESTER (FRP) PROPERTIES
FRP material is highly resistant to tension and compression stresses and to impact forces as well; making it a frequently used material in structural applications.
As a rule of thumb, an FRP laminate requires three times the thickness than a steel laminate in order to have the same mechanical resistance.
A very simple analogy can be used to have a clear understanding of the FRP properties: The Polyester Resin can be seen as the Cement and the Fiberglass as the corrugated bars in reinforced concrete.
FRP has at least twice the mechanical resistance of HDPE.
There are several types of polyester resin available in the market for different applications and resistances. The highest protection against environmental attacks is reached by using Premium Isophalic Polyester Resin with UV inhibitor in the manufacturing process of all our Cooling Towers. The life of FRP with Premium Isopthalic resin is said to be endless, however, REYMSA recommends using 30 years when making a life-cycle cost analysis.

Direct drive transmission that eliminates the use of pulleys, belts and bearings.
Our direct drive motors eliminate the frequent service required by the V-belt drive transmissions that have higher operational and maintenance costs. Typically a V-belt drive transmission requires quarterly service for checking and readjusting the tension of the belt, lubrication of fan shaft bearings, lubrication of the motor base adjusting screws and drive alignment to ensure maximum belt life.
Also, by having fewer components between the fan and the motor, the risk of a failure causing a sudden stop of the fan and higher operational water temperatures that may in turn stop the entire air conditioning system is reduced to a minimum.
REYMSA uses the best fan in the market; manufactured using cast aluminum hubs and adjustable pitch air foil blades molded with engineering thermoplastics.
Blade materials: fiberglass reinforced polyamide, which is spark and corrosive resistant and is able to resist high vibration levels and high temperatures. Ambient operating air temperatures may fluctuate from – 50°F to 250°F.
Fan Motors: all our Tower models feature motors that exceed the Cooling Tower duty characteristics. REYMSA Fan Motors are NEMA Premium Efficient, TEFC, 1.15 service factor, 100% cast iron construction for SEVERE DUTY, INVERTER DUTY, and MARINE DUTY applications, EPOXY PAINT, inpro/ seal vbx bearing isolators on both ends of the shaft, brass drain and breather, 6-60 hz variable torque.

EASY, REMOVABLE, ENVIRONMENTALLY FRIENDLY AIR INLET LOUVER DESIGN
Our triple pass PVC air inlet louvers are designed to block direct sunlight to the water, to minimize splash-out, and to reduce noise; while at the same time having a low pressure drop that results in less fan motor energy consumption. By blocking direct sunlight and allowing very little light to pass into the tower, the potential of algae growth is reduced and therefore so are the water treatment and maintenance costs. Additionally, the Louvers are durable, corrosion resistant, and impervious to chemical attacks. The PVC is specially formulated for UV and fire resistance and is non-combustible and self-extinguishing.
EASY MAINTENANCE AND CLEANING ACCESS
Wide and easy access for monitoring or cleaning the inside of the Tower and the cold water basin by removing the access door or the air inlet louvers.

EXAMPLE:
Select the HRFG Model REYMSA Cooling Tower to cool 1200 GMP of clear water from 95 °F to 85 °F at entering air wet bulb of 78 °F.
STEP 1 RANGE is equal to the temperature differential between the entering water temperature ( T1 ) and the leaving water temperature ( T2). (95 °F - 85 °F ) = 10
STEP 2 APPROACH is equal to the temperature differential between the leaving cool water temperature ( T2 ) and wet bulb temperature ( TWB ). ( 85 °F - 78 °F ) = 7
STEP 3 From Section A: TOWER SELECTION FACTORS; Select the apropriate wet bulb temperature table ( 78 °F ). Select the range column ( 10 ) and in Approach row ( 7 ), the Tower Selection Factor = 4.8
STEP 4 Next, go to Section B: CAPACITY TABLES; Enter the column headed by the “ Tower Selection Factor ” determined from Section A ( 4.8 ) and read down that column to the desired cooling water flow rate equal to or greater than that specified ( 1200 gmp ). Look to the left on the row with the desired cooling water flow and read the corresponding HRFG816215 REYMSA Cooling Tower model to satisfy your requirements.
