Detailed Features

All Delta Cooling Towers are factory assembled to the fullest extent possible for ease of installation and shipment. The following features are standard to our TM Series™ Induced Draft Cooling Towers:

Shell: Shell is seamless, double wall, non-corroding, hi-impact high-density polyethylene (HDPE) of leak proof design. Conical transition for motor/fan assembly with separate polyethylene velocity recovery stacks. The shell exceeds ¼” average thickness. The structural shell is capable of withstanding water temperatures up to 160°F on a continual basis. Between equidistant vertical ribs along the walls are pre-contoured sections that when coupled with the structural foam between the double walls, creates a pre-stressing that adds rigidity and overall structural strength of each cell.

Sump: Sump is seamless, double wall, non-corroding, hi-impact high-density polyethylene (HDPE) of leak proof design. Sump will be sloped toward outlet. Integral molded-in I-Beam support pockets allow placement on elevated I-Beams. Integral support posts 360° around sump give support to upper tower section and allows mounting of louvered inlet panels for optimum air distribution.

Sloped “Clean” Sump Design: Each cell’s sump is molded to slope aggressively towards the center and a 3% slope towards a depressed sump box near the outlet. This limits settlement of any dirt, debris, or biological films and allows for complete drainage of the sump during planned shutdowns.

Water Distribution System: Totally enclosed, non-corroding, polyvinyl chloride (PVC) pipe with large orifice non-clog spray nozzle distribution system. Threaded nozzle orifices shall be interchangeable allowing substitution of larger diameter orifices for increased flow conditions without increasing inlet pressure.

Wet Decking: Rigid PVC film, corrugated and bonded for maximum 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 on the velocity recovery stack, and 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 manufacturers warranty. 

Fitting Connections: PVC fittings are provided for inlet, outlet, overflow, drain and make-up connections at standard orientation locations. Orientation for special requirements is available for new and replacement installations.

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

Cutaway View

1 - Lightweight And Double Wall: Plastic is lighter than conventional cooling towers and integrated double-wall is more than 10 times the average wall thickness of metal towers

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

3 - Self Supporting Plastic Base: Tower can be set on flat surface or on I-Beams placed in Integrally-Molded I-Beam Pockets for elevated installations

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

5 - Drift Eliminator: Three pass PVC drift eliminator prevents water droplets from leaving the tower

6 - Nozzle Water Distribution System: Non-Clog large crifice removable nozzles evenly distribute the water

7 - Fill Material: High efficiency PVC cellular design for maximum cooling

8 - Direct Drive Air Moving System: Totally enclosed VFD rated cooling tower motors power multiple fiber-reinforced polyproplene axial propleller fans within a polyethylene velocity recovery stack

The Most Durable Corrosion-Proof Cooling Towers Available
