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 on our Premier™ Series Induced Draft Cooling Towers:

Shell: A seamless engineered polyethylene (HDPE) molded shell, with conical transition for motor/fan assembly and integrally molded louvered inlet section around base of cooling tower integrated for optimum 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.

Wet Decking: Non-corrosive, polyvinyl chloride (PVC) wet decking, 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 manufacturers warranty.

Fitting Connections: PVC fittings are provided for inlet, outlet, overflow, drain and make-up connections at standard orientation locations. Orientat

Cutaway View

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

2 - Leak Proof Sump: Molded as unitary (one-piece) structure that has no joints to leak or require recaulking and sealing

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

4 - Nozzle Water Distribution System: Non-clog, large orifice removable spray nozzles evenly distribute the water

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