Basic Specs

Highly Efficient & Environmentally Friendly Cooling Towers

The Delta PARAGON® Induced Draft Tower is an induced draft cooling tower making it perfect for a wide range of industrial and HVAC applications. Induced draft towers tend to be more cost-effective and sustainable than forced draft models because they circulate the air more efficiently. This means they need less energy to power the unit. They operate with a larger fan but need a smaller horsepower (hp) motor.

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

Hardware: All fasteners are 304 stainless steel. Anchor and lifting lugs are aluminum.

1 Corrosion-Proof Shell: HDPE Plastic Construction cannot corrode and is backed by 20 Year Warranty

2 Lightweight And Heavy Duty: Plastic is lighter than conventional cooling towers and the average wall thickness is 5-10 times sheet metal towers.

3 Leak Proof Sump: Molded as a Unitary (One-Piece) Structure that has no joints to leak or require recaulking and sealing

4 Water Distribution System: Self-propelled multiple PVC rotating arm system evenly distributes the water, fixed nozzle distribution system also available

5 Drift Eliminator: Polyethylene drift eliminators prevent water droplets from leaving the tower

6 Fill Material: High-efficiency spiral wound PVC cellular design for maximum cooling

7 Direct Drive Air Moving System: Totally enclosed PVC-rated cooling tower motor that powers a fiber-reinforced polypropylene axial propeller fan.

Water cooling towers use simple laws of physics to transfer heat energy from one location to another. In an induced draft cooling tower, the air is drawn into the unit by the fan on the top. Then, it is drawn quickly upwards with a large fan that rests at the top of the tower. At the same time, water is distributed downward and cooled by the air; then, that cooled water is circulated back to the industrial process or HVAC chiller. A drift eliminator captures any large droplets and keeps them within the cooling tower.

Overview of Water Cooling Towers

Water cooling towers are used to cool machinery whether it is the condenser loop in an HVAC chiller or 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 by 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 an 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 the production of an expensive product. A cooling tower is a vital investment in the safety and extended lifecycle of your industrial machinery.
