TM Series™ Cooling Towers

Delta’s TM Series™ induced draft, counter flow design are available in single unit capacities from 250 to 2,000 cooling tons.

Manufactured since 2001, the TM Series™ has been very well received in both commercial and industrial applications.

The modular design allows isolation of cells for operational flexibility.

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.
1 - Lightweight And Double Wall: Plastic is lighter than conventional cooling towers and integrated double-wall is more than 10 teims 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 can not corrode and is backed by 15 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
