Spx Cooling Tower Nozzles

SPX Cooling Technologies (Marley brand) provides a wide range of cooling tower spray nozzles, which are critical for distributing water evenly over the fill media for effective heat transfer.

Here’s an overview of SPX/Marley cooling tower nozzles:

Types of SPX (Marley) Cooling Tower Nozzles

1. Marley Spiral Target Cooling Tower Nozzles (ST Nozzles)

Most widely used in Marley towers.

Spiral design creates a uniform spray pattern.

Made of glass-filled polypropylene (corrosion resistant).

Available in different orifice sizes (to match flow requirements).

Common in counterflow towers.

2. Marley XCEL Spray Cooling Tower Nozzles

Designed for high-efficiency water distribution.

Produces consistent droplet size for better heat transfer.

Good for reducing drift and water loss.

3. Marley HP (High Performance) Cooling Tower Nozzles

Used in larger towers.

Ensures full water coverage across wide fill areas.

4. Marley Flow Control Nozzles

Provide controlled water distribution.

Often used in replacement/retrofit applications.

Materials

Glass-filled polypropylene (standard).

ABS plastic or other engineered plastics (for chemical resistance).

Functions of Nozzles in Cooling Towers

Distribute water evenly over fill media.

Prevent dry spots (which reduce cooling efficiency).

Control water droplet size (too fine = drift loss; too large = poor cooling).

Maintain tower performance even with flow variations.
