Cross Flow Spiral Target Nozzles
SPIRAL TARGET NOZZLES
Features
- Made of inert injection moulded Polypropylene.
- Single assembly – no moving parts.
- Removable & Replaceable in the floor of the basin.
- Provide full coverage to the fill by gravity flow.
- Consists of the nozzle body (integral target diffuser) & a snap-on metering orifice (insert) to handle the water flow rate of the cooling tower.
- Bottom portion of the nozzle body referred to as the daisy consists of six leaves designed to create an efficient break up of water.
- Differentiated in terms of length the spiral target nozzles are available as four different models.
Small Gravity Nozzle
Features
- Measures 2.625″ from the bottom of the daisy to the top of the nozzle. Commonly referred to as Short-Stem nozzle.
- Available in 9 different Orifice sizes ranging from 3/8″ (coded 030) to 1″ (coded 066).
- These small spiral target nozzles are used on Wood, Steel, and Fibre Glass cooling towers where basin support structure does not obstruct the release of water.
