Detailed Features
Delta Cooling Towers Offer Cutting-Edge Engineering
All Delta Cooling Towers are factory assembled to the fullest extent possible for ease of installation and shipment. The following features are standard on our Paragon® Series Induced Draft Cooling Towers:
Shell: A seamless engineered polyethylene cylindrical (HDPE) molded shell, with conical transition for motor/fan assembly, louvered inlets and fitting orientation. Louvered inlets are designed for 360° air distribution. There are no joints, seams, panels, gaskets, bolts, fasteners or caulking like conventional towers.
Sump: Sump is integral with cooling tower shell, creating a one-piece seamless structure.
Water Distribution System: A self-propelled PVC distribution system incorporating a rotating sprinkler head and lateral distribution arms with integral drift eliminators. An inspection port is provided in the cooling tower shell at the lateral arm elevation for adjustment. (Non-rotating water distribution system is also available).
Wet Decking: A continuous wrapped spiral configuration of lightweight PVC, bonded and packed for maximum film cooling efficiency.
Fan Assembly: The fan assembly consists of a fan ring, propeller, motor and guard. The fan ring is coated with premium plasite coating ideal for the harshest corrosive environments. An adjustable pitch propeller fan, fiberglass reinforced polypropylene with a silica alloy hub, is directly driven by a totally enclosed VFD Premium rated motor designed for cooling tower duty. A fan guard is included that allows protection from the propeller and access to the motor.
Motor: Totally enclosed air over (TEAO) VFD rated motor with 1.15 service factor, designed for 208 or 230/460V 3 phase 60 cycle operation and suitable for outdoor service. Motor is provided with a 5-year motor manufacturer’s warranty.
Fitting Connections: PVC fittings are provided for inlet, outlet, overflow, drain

Overview of Water Cooling Towers
Water cooling towers are used to cool machinery whether it is the condenser loop in a HVAC chiller or an industrial process machinery that generates heat and needs to be cooled to remain operating. Many applications on the HVAC side include large office buildings, hospitals and schools while on the industrial side applications include numerous manufacturing process industries, including chemicals, metals, plastics, pharmaceutical, oil, and nuclear.
The towers work by drawing air into the unit and cooling down the water through evaporating a portion of the water. The cooled water prevents your machinery from overheating and allows it to perform optimally. It also makes the atmosphere of your building more pleasant for everyone in a HVAC application.
Delta’s water cooling towers come in a range of sizes, from relatively small rooftop units to towers that cool a large hospital. The Delta PARAGON® Induced Draft Tower ranges in size from 84" x 146" with a capacity of 55 cooling tons to a size of 114" x 210" with a capacity of 250 tower tons.
Practical Applications of a Cooling Tower
In some industries, such as the nuclear power industry, cooling towers are essential to maintaining the nuclear reactor from overheating. This prevents your machines from overheating, shutting down, needing costly repairs and stopping production of an expensive product. A cooling tower is a vital investment in the safety and extended lifecycle of your industrial machinery.

The Difference between Natural Draft, Induced Draft, & Forced Draft Cooling Towers
There are a few different types of cooling towers. These include natural draft cooling towers, induced draft cooling towers, and forced draft towers. Natural draft towers use the principle that heat rises and feature a stack design to allow heat to escape the building while circulating cooler air back into the building. Induced draft cooling towers use fans to pull the hot air from the building and water to cool it. Forced draft cooling also uses a fan to draw hot air out of the building, but the fan is generally outside the building and circulates the air from bottom to top.
