CATALOGUE - INDUSTRIAL TANK WASHING SYSTEM

Product catalog summary
Overview
PNR Italia specializes in the production and marketing of spray nozzles and systems for industrial applications, including tank washing systems. Established in 1968, the company has expanded through international partnerships and continuous investment in research and technology.
Industrial Tank Washing Systems
  • Tank Washing Techniques: Efficient cleaning processes are crucial for maintaining product quality and reducing effluent disposal costs. Key factors include proper filtering, washing cycle selection, and motive mechanism.
  • Cleaning Radius and Efficiency: The cleaning radius is determined by specific conditions, while the wetting radius ensures complete surface coverage. Efficiency is assessed by evaluating the wetting radius, capacity, and impact force of the jets.
  • Cleaning Validation: Techniques like Riboflavin testing and ATP-metry are used to verify cleaning conditions and ensure no organic residues remain.
Technical Specifications
  • Fixed Spray Heads: Designed for simple rinsing in small tanks, models like UA3, UAB, and UAC are made from high-quality stainless steel for easy cleaning and maintenance.
  • Single and Twin Axis Heads: Single axis heads rotate around a vertical axis, suitable for low-resistance products, while twin axis heads rotate around both horizontal and vertical axes for stronger washing actions.
  • Materials and Compliance: Products are made from FDA and CE approved materials such as AISI 316L, PTFE, and PEEK, complying with standards like 3-A Sanitary Standards and MOCA for safety and hygiene.
Applications
PNR Italia's products are used in various industries, including food and beverage, pharmaceuticals, cosmetics, and transportation, suitable for cleaning a wide range of residues and equipment types.
Conclusion
PNR Italia offers a comprehensive range of tank washing solutions tailored to meet diverse industrial needs, ensuring efficient and hygienic cleaning processes.

TANK WASHING TECHNIQUES The continuous research for higher efficiency in all kind of industries, and the requirement to assure a constant and higher quality level for their products, highlight the necessity that every step in the production, stocking and transporting processes are performed using adequately clean systems and tanks. At the same time, as disposing of liquid effluents is becoming more and more costly, it becomes necessary that each cleaning process, while reaching a totally satisfactory result, is performed using the lowest possible volume of cleaning solution. The two above factors...

EFFICIENCY ASSESSMENT It is very difficult to assess such value as the efficiency range with reference to a given tank washing device without taking into considerations the various parameters relating to the process conditions, such as the materials you have to remove, working temperature and pressure, the time of every washing cycle. While choosing a tank washing head, you have to consider if: • the wetting radius is adequate for the dimension of the tank • the capacity can provide the whole inner surface with a correct amount of washing solution for square measure; • the impact force of the...

FIXED SPRAY HEADS UAC fixed spray heads are a simple, fast and efficient device for cleaning the inside of small size tanks where a simple rinsing action is required. Because of the relatively high washing fluid flow rate, they are usually operated at low pressures and can achieve a limited impact action on the tank wall. Their simple design allows for the head to be easily cleaned after being operated, which makes it possible to leave the heads permanently in place ready for use. The values for wetting radiuses shown at the right of the table have been obtained operating the heads with a water...

SINGLE AXIS HEADS REACTION DRIVE The washing action is obtained through water jets coming from a rotating head, where the head motion is obtained purely through reaction force originated by the fluid jets being ejected. The operating pressure influences the head rotation speed, which must be limited to avoid the water jets being broken into minute droplets and loosing part of their impact force. These devices perform very satisfactorily in a great number of general applications, where the products to be washed away do not originate severe problems and with limited size tanks. To cope with the...
