PNR’s Spiral Nozzle – sometimes called Pigtail nozzles due to their shape – is a powerful ally in the fight against fugitive dust in mines, quarries, recycling plants, building sites and more

The unique design of the PNR Spiral Nozzle makes it ideal for suppressing dust in situations where there is a risk of clogging.

“Because it doesn’t contain an internal swirling vane, fluids can pass through very freely,” said Graeme Cooper, Managing Director of Tecpro Australia, exclusive distributor of the PNR range in Australia and New Zealand. “This means that this type of nozzle easily tolerates the flow of dirty recycled water, which is often used in dust suppression.”

The PNR Spiral Nozzle atomises fluid into fine droplets which is dispersed in a full cone pattern.

“The fluid hits the spiral blade and fans out in a circular pattern,” said Mr Cooper. “Because this nozzle has a relatively large internal chamber, it poses little resistance. This means that the nozzle is much less likely to clog up, compared with conventional nozzles.”

The pigtail design used in the PNR Spiral Nozzle has been used successfully in a variety of environments over several decades.

“Apart from being used for dust suppression, pigtail nozzles are also highly effective in fire protection, evaporative cooling and other situations where a fine vapour is needed and there is a risk of clogging,” said Mr Cooper.

Tecpro Australia offers a wide range of dust suppression solutions including fog makers and low pressure, high pressure and ultrasonic products. The company also offers an on-site consultancy service to guide and advise clients on the best choice of dust suppression system to suit their environment.

“Every situation is completely different,” said Mr Cooper. “We draw on several decades of experience in making our recommendations to eliminate the dust problems being experienced by our clients.”
