How long does it take to process orders? Our warehouse is extremely well-stocked, we are able to process about 50% of orders within 24-48 hours. If the product is not in stock we will process your order as quickly as possible.
How much does the shipment cost? Each shipment is affected by factors such as destination, weight and size of the order and also by the distance from our site. Contact us for further information.
Where do you make your products?All our products are Made in Italy, produced directly in our company based in Voghera (PV- Italy). It is a great pride for us to be able to invest in Italian products and qualities and support our country and the entire supply chain.
What is a nozzle? A nozzle is a device which converts the energy from a fluid into velocity of the spray droplets. Applications in many industrial processes are numberless, with spray nozzles being very often a critical component in determining the final quality of the product or the efficiency of the process.
Based on the operating principle: with pressure chamber, impact or compressed air atomizers.
When is a nozzle to be considered defective? PNR products will be replaced and/or repaired at PNR’s discretion free of charge if they are found to be not in conformity due to manufacturing, packaging or incorrect labelling. The above conditions will only apply if PNR receives the written non-compliance report within 30 days from the date of product installation or within one year from the date of shipment. The cost of above said replacement or repair shall be the exclusive remedy for any breach of any warranty, and PNR shall not be held liable for any damage due to personal injuries or commercial losses coming from product malfunction. Our product guarantee addresses all these aspects in depth.
How often should a nozzle be changed? The choice of the most suitable material for a nozzle is of primary importance, as the operating life of a nozzle depends upon it. Several factors affect the life of a nozzle or decrease, such as:
Wear caused by solid particles suspended in the liquid being sprayed;
Chemical corrosion caused by the sprayed liquid;
Chemical corrosion caused by the external environment where a nozzle is used;
Exposure to high temperature;
Exposure to mechanical shocks.
The mechanical characteristics of the materials in which we make our nozzles and their chemical resistance are available from page 29 onwards of our Spray Engineering Book.
How can I identify the nozzle code? Like any other industrial product, a nozzle must be precisely identified by a code, which prevents confusion and allows the products to be managed electronically. We have therefore created a coding system produced according to the following scheme:
What is a twin fluid atomizer? The atomization of a liquid by means of a compressible fluid like air, steam or a gas, is defined pneumatic, two-phase, or twinfluid atomization. Various industrial processes require the atomization of liquids in fine or very fine drops. This could be achieved by spraying the liquid with an exclusively hydraulic atomizer, where the liquid is sprayed under pressure by means of a small orifice. In most industrial processes a fine atomization is obtained by means of compressed air atomizers, which provides the energy necessary to atomize the liquid. This technology, although relatively expensive, allows to obtain fine and also extremely fine drops that can meet the needs of current industrial applications.
