Delta’s FRP Cooling Towers (bottle shape design, FRP induced) are known for superior design and technology. These have made Delta’s DFC-50 Series towers the standard of bottle shape cooling towers. The series has been designed to meet the high standards demanded by engineers, who require a compact, heavy duty and efficient cooling tower with a long service life and an aesthetic design. Proven in many industries for over 2 decades, these towers have an advantage of compactness and are extensively used in many industries and in HVAC applications.
Being round, the air flow through the Draught Cooling tower is more evenly distributed. Structural members do not interrupt air intake and therefore they have been proven to be thermodynamically the most efficient design in the field. This translated directly into reducing running costs. The tower offers PVC fills and eliminators in a design that maximizes economy and efficiency. The counter flow design facilitates low pump heads. The water is distributed inside the tower over the fill area through the self rotating sprinkler so as to give an even distribution over the complete fill area.
DESIGN
FRP Cooling Towers are of vertical induced draught counter flow design with uniform water distribution and optimal heat transfer. Cooling towers can be installed independent of wind velocity.
AXIAL FAN
Especially designed energy efficient fans are induced draught axial type with adjustable pitch. Fan blades pitch is factory set and dynamically balanced.
CASING
The tower is made of tough fiberglass reinforced plastic (FRP induced cooling towers) and has sufficient structural strength to withstand high wind velocity and vibrations. Gel coat is used for UV rays protection and longer life. The water sump is also of FRP and is leak proof.
FILL
The fill is of rigid poly vinyl chloride (PVC) and is of honey come design with very large contact surface area. The purpose of fill is to split the water and air into several streams to increase the time of contact and also heat transfer between air and water. The fills are available with standard size of 24” x 12” x 6” with the thickness of 0.25 mm.
.MOTORS
The motors are totally enclosed (IP-55) flange type, 415 V, 50Hz., induction weather proof with extended shaft and are especially designed for cooling towers..
DRIFT ELIMINATOR
The FRP (induced) eliminator attached to the sprinkler reduces the drift loss of water and it is made of rigid PVC material.
SPRINKLER
Sprinklers are available in Brass/ SS/ Aluminum / PVC and the sprinkler pipe distributes the hot water over the entire space of the fill area. Sprinkler pipes are non- clogging and require low pressure to operate and assures uniform water flow.
Delta’s DFC-60 Series Cooling Towers utilize the induced draught counter flow principle of operation. Heated water enters via the hot water inlet passing through perforated branch pipes spreading the water evenly by the splash caps. Water is distributed over the heat exchange fill. Water flows as a thin film downward through the fill coming into direct contact with ambient air traveling upwards in a counter flow direction.
Water cooling is affected by heat transfer to the air in the form of evaporation and convention. To prevent carry – over of water droplets by the fan, drift eliminators are mounted above the water distribution. The drift eliminator controls drift loss to less than 0.02 % of water in circulation.
Great flexibility is introduced by multi-cell cooling towers which can be tailored to meet individual cooling requirements and conditions. This design also assures a high degree of availability.

DRIFT ELIMINATOR
The FRP eliminator reduces the drift loss of water and it is made of rigid PVC Section..
NOZZLE
The performance of the Cooling Tower greatly depends upon the water distribution over the fills. Nozzle distributes the water evenly through a wide spray angle. They are light weight and reduce the frequency of clogging.

To ensure that the best performance is achieved and the power consumption and noise levels are as low as possible, it is of the most importance that the right fan is chosen.
Axial Flow fans are Delta's business. With an extensive product range and with a high level of technical support 'DELTA' is a natural choice, when ventilation is required. Aerodynamic axial flow FRP manufactured by Delta Cooling Towers P. Ltd. are specifically designed for Cooling Towers and other efficiency critical applications.
Delta's energy efficient fan saves upto 30% power as compared to conventional aluminium fans.
DESIGN
Tough light weight hollow FRP blades
High corrosive resistance
Different standard pitch angles
Wide range of Industrial air moving applications
Aerodynamically designed for maximum airlift and minimum air resistance
High efficiency and low noise levels.
Delta's unique aerofoil design ensures high efficiency, lower noise levels and less power consumption. Reinforced Fibreglass Epoxy Resin (FRP) provides the desired non-corrosive quality to the fan blades, resulting the operation of fans even in the very aggressive environment.
Delta's light weight FRP fans ensure a low moment of enertia, minimum wear and stress on motor, bearing and drive. Hollow FRP blades reduce material cost, installation costs and possibility of damage to the fan and drive during sudden stops.
FLEXIBLE DESIGN AND ADJUSTABILITY
Delta's FRP fans with adjustable pitch enables the technicians or engineers to change pitch settings easily in order to optimise fan performance or to change field applications..
UNIFORM VELOCITY
FRP cooling towers have 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 Delta fan blades are Jig-formed to provide the complex contour needed for high aerodynamic efficiency..
BALANCING
Delta's fans are electronically balanced on computerised balancing machines to ensure maximum output..
SIZE RANGING
Delta's fans are available in the sizes ranging from 3 feet to 30 feet diameter. Fans of higher sizes can also be provided on request.
An on line non - Chemical Water Treatment Device is a most reliable scale prevention method having many advantages over other water treatment systems. Only one time installation cost will help you in improving efficiency of the system and saving of energy without changing the chemical composition of water. |
