Delta’s FRP bottle shape Induced draught Cooling Towers 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.
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.
Especially designed energy efficient fans are induced draught axial type with adjustable pitch. Fan blades pitch is factory set and dynamically balanced.
The tower is made of tough fiberglass reinforced plastic 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.
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.
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.
The FRP eliminator attached to the sprinkler reduces the drift loss of water and it is made of rigid PVC material.
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.
