The performance of cooling tower greatly depends upon the water distribution over the fills. Cooldeck nozzles distribute water evenly through a wide spray angle without any dry pockets. They are lightweight and reduce the frequency of clogging.
The Solid Cone Square Pattern (SCSP) nozzles produce a solid cone spray of water that is distributed in a square pattern onto the fills. These nozzles can be used on new/existing pipe, which may be of MS, PP, PVC or AC pipes.
Our SCSP nozzles are provided with 2.5" BSP threads and can be conveniently assembled onto any adapter having 2.5" BSP Threads using the easy locking mechanism.
We manufacture adapters, suitable for assembling these nozzles, which may be inserted in AC pipes/PVC/PP Pipes.
These nozzles are made out of a basic body of ABS plastics and three different types of nylon inserts and turbulators. The turbulators and orifice when assembled with the ABS body generate three types of nozzles capable of discharging water flow rates ranging from 30 GPM to 120 GPM. Depending upon the selection, each nozzle covers an area of 2'X2' to 4'X4' of tower area. A water flow chart to determine the selection may be provided on request.
CoolDeck also manufactures the commonly used flower type nozzles for Crossflow towers and whirl spray type nozzles for Counterflow packaged towers with ½", ¾" and 1" BSP threads.
Film types fills have been popular with the Cooling Tower Industry as a result of their efficiency of not only handling large quantities of water but also the overall tower efficiency. However in the case of heavily contaminated water, film type fills are susceptible to accumulating deposits and often make way for the use of splash type fills for effective water cooling.
Cool Deck Bio Media have folded edges at the top and bottom that provide critical leading to resistance to mechanical damage and erosion. They are continuous formed and have uniform thickness. The Bio Media have a high surface area and the aeration is done by means of natural draft. Cool Deck Bio Media have a long retention time and are minimum blocking. The raw material used is the self extinguishing PVC.
Cooldeck has a range of products in the Splash type fill environment, including V-Bars, Perforated Slats, Triangular Bars, Rectangular Slats, and Polypropylene Slats. Our engineers can recommend the right solution for your applications.
Perforated V-Bar is the most extensively used product in the industry. The standard sizes as well as the standard diamond shape perforations in the `V' Bar ensure the cooling tower to perform as published in the CTI bulletins - particularly for the configurations - 8" x 8"perpendicular to airflow, 8"x 8" parallel to airflow and 16" x 8" parallel to airflow. This enables the Cooling Tower designer to have the complete information about calculating the thermal capabilities of the cooling tower along with its power requirements. These Splash Bars are supported on lightweight thin section grids.
The V-Bar system has proven to be a superior system to upgrade Cross Flow cooling towers that have wood splash fill and for new construction where dirty water would clog film fills. Existing Stainless steel or PVC coated wire mesh allows for a complete system utilizing the available splash bar technology.
Cool Deck's V-BAR clip design provides secure locking capabilities preventing wear on both the wire hanger and the fill. The raised center rib and the tab locks prevent the V-BAR from slipping once locked into place. Clips are made of Copolymer Polypropylene - a high impact resistance material able to remain flexible in a broad range of temperatures.
Cooldeck offers perforated slats having surface and splash area equivalent to timber section of 1 ½" X ½" (most extensively used fill in wooden towers) giving an equivalent thermal performance. The diamond shaped perforations made out on the slats reduce the pressure drop considerably. The tower efficiency can be increased by up to 15% by offering a higher airflow for the same power and configuration or by reducing the power required to maintain the same airflow.
Cool Deck offers a wide range of edge folded PVC fill products to meet your specific applications. The CD-XX series meets the standard requirements used in counterflow cooling towers while the CD-XF fills have been uniquely designed to provide optimum performance for crossflow cooling towers.
These fills have been successfully deployed in various industries including humidification, effluent treatment, power, petrochemical, refining, paper, chemical, steel and others.

Global environmental concerns have directed attention to the discharge of wastewater. Biological wastewater is treated by aerobic or anaerobic processes. COOL DECK Bio Media are specially fabricated PVC media that aid removal of biological wastes from water. Cool Deck Bio Media are designed to achieve high surface area per given volume resulting in high specific mass transfer. The structure aids uniform growth of biological film. Micro-organism growth on the bio film convert the dissolved and ‘unsettleable’ colloidal impurities into a settleable biomass. Other areas of application for Cool Deck Bio Media are Nitrification and Degasification.

Clarification/Sedimentation is the most important stage in the field of waster water treatment. The most efficient sedimentation systems have high settling surface area whilst maintaining a small structure. Cool Deck clarifier media provides a large settling surface area within the specified volume thus giving high flow rates. They have a chevron shaped self-supporting structure in a tubular form with six sides. They are primarily used in applications like water treatment, primary & secondary clarifiers in wastewater treatment.
Cool Deck Clarifier Media have no moving parts as a result of which there is no energy loss. The distribution and entry velocity are minimum resulting in maximum efficiency and better effluent quality. The efficient design minimizes space requirements and is sturdy and easy to transport and install. Cool Deck Clarifier Media increase the capacity of clarifier due to increase in area.

SCS aerodynamically designed Aerofoil axial flow fans manufactured from high quality FRP material save up to 30% power as compared to aluminum fans. SCS fans achieve the best performance keeping power consumption and noise levels to the minimum possible.
Aerodynamic axial flow FRP fans manufactured by SCS are specially designed for efficiency critical applications, which include Cooling Towers, Humidification and Exhaust fans.
Key features include:
Tough light weight hollow FRP blades
Non corrosive and erosion resistance
Different standard pitch angles/adjustable pitch angles
Wide range of industrial air moving applications
Aerodynamically designed for maximum airlift and minimum air resistance
High efficiency and low noise levels
Efficient Design: SCS's unique aerofoil design ensures high efficiency, lower noise levels and less power consumption. Reinforced Fiberglass Epoxy Resin (FRP) provides the desired non-corrosive quality to the fan blades, resulting the operation of fans even in the most aggressive environment.
The design of SCS fans provides high air volume with optimum pressure to ensure the long distance reach in the farthest areas. The hollow construction of blades makes the fan lightweight resulting into low starting torque and reduced power consumption under varying load conditions. This causes minimum wear and stress on motor bearings and drive shafts. By varying chord width and angle of incidence along the length of the blade by SCS fans that yield significantly higher performance than constant-chord-width fans.
Flexibility of Design: SCS's FRP Fans with pitch control enable the field technicians to change pitch settings easily in order to optimize fan performance or to change field application.
Uniform Velocity: Uniform velocity over the entire blade area is the most important criteria of efficient axial flow fan design. To produce a uniform velocity through out its length, a fan blade must vary from a thin tip to a thick cambered root. Each point on the blade must have the proper combination of chord (Blade width) and angle. This results in a great deal of twist in a properly designed blade, a shape impossible to produce by extrusion. The SCS fan blades are jig-formed to provide the complex contour needed for high aerodynamic efficiency.
Energy saving: Get More Air or use Less energy - SCS fans provide 30% power saving or up to 10% extra airflow. As a result, the usual payback period for replacing aluminum fans is only 4-6 months. In a condition when power consumption is the important factor, blade angles are set to give the required airflow at the lowest power consumption. Alternately for the toughest duty condition when the airflow requirement is highest the blade angles can be set to give maximum performance from the existing conditions of power consumption. Any of these advantages can be suitably chosen at the time of fan installation.
Cooling tower fans are designed considering the pressure drops of the cooling tower fills, drift eliminator, inlet louver etc. The pressure drops come by way of velocity head in discharging the air after cooling. Most of these applications required pressure drops varying from 7 mm water to 20 mm of water column. These fans are designed for optimum-design conditions of the cooling tower. The usage of these fans is crosschecked for application in varied conditions like the changes in the press drop.
Cool Deck drift eliminators, made out of rigid pvc, are designed to remove entrained particles from air steam efficiently, with minimum pressure drop, thereby reducing the fan power requirement when the air passes through the drift eliminator. Water droplets are separated from the air drift at the three direction change points on the drift eliminator.
For Crossflow tower applications, the almost vertical water conduits provided by the CD-100 drift eliminator remove the water droplets out of the drift eliminator area and return them back into the tower and does not allow any re-entry.
The special locking pin arrangement for CD-100 facilitates quick and simple assembly at site.
For Counterflow applications, the CD-S130 drift eliminator provides a cellular rugged structure with a very low pressure drop. This results in high drift elimination efficiency while exerting minimum driving force on the fan.
The CD-S130 drift eliminators get an S-shaped tubular structure as a result of their fabrication. Individual S-shaped corrugated sheets are bonded with subsequent layers to create the structure. The entire area is thus divided into several fine S shaped mini zones each removing water droplets on the entire surface of the cell.
SCS Exhaust fans are manufactured with a suitable cylinder to house the fan. This primary requirement along with the velocity head that an exhaust fan is required to develop to force the air at required level are the key considerations in the design of SCS Exhaust fans. Other important criteria in the design of SCS exhaust fan are those of the low speed of fan and consequent low noise level at highest efficiency. SCS Exhaust fans are available with fixed blade angles in sizes of 18"x 24".
These fans are designed to suit varying conditions of operating departments in industries such as textile processing. The pressure range of operation of these fans is 20 mm to 50 mm. SCS humidifier fans are specifically designed to suit these requirements. Common sizes in this category are 900 mm to 1600 mm diameter.
