With over 90% of aluminium cans recycled, the metal beverage packaging and can making sectors are rapidly rising as the sustainable alternative to plastic manufacturing. In the transition toward a greener future, beverage cans made in aluminium are capturing growing market shares from plastic containers which are known for their low recycling rates and significant environmental pollution.

As consumer preferences shift towards eco-friendly options, aluminium cans emerge as the preferred choice due to their durability, recyclability, and ability to preserve the quality of the contents. Every aluminium can produced by the beverage packaging industry can be recycled indefinitely and may be reused without any limitation or loss in its intrinsic aluminium characteristics.

The growing demand for beverage packaging is driving innovation in the can making sector. The modern two-piece can industry produces on average over 3,000 aluminium cans per minute. In this fast and highly demanding manufacturing environment, unplanned machine downtimes must be avoided, making the selection of efficient pneumatic equipment crucial to maintain high production standards.

Without the supply of vacuum and compressed air, the can making process would halt. The production line in a can factory is a sequence, starting with aluminium coils at the entrance and ending with finished, printed and coated aluminium cans at the exit. Throughout this process, compressors and vacuum systems are essential in most manufacturing steps.

Over half of the electric energy consumption in a can plant is due to the continuous operation of vacuum pumps and air compressors. Therefore, choosing pneumatic systems with the lowest Life Cycle Cost (LCC) is crucial. The Life Cycle Cost is the sum of all costs incurred during the life time of a machine, including Purchase Price, Maintenance Costs for spare parts, labour and Power Consumption. Over a 15-year analysis, the overall energy cost becomes the largest expense, often exceeding the purchase price of the machine by a factor of 50. Here is where the value of Pneumofore appears as the ‘best in the class’.

Can making factories typically use centralized compressed air systems with pipeline networks operating at different pressure levels: a low-pressure line at 3.5 bar(g) and a high-pressure line at 7 bar(g). Additionally, a dedicated vacuum pipeline system usually runs at 300 mbar(g). Under these conditions, Pneumofore’s large vacuum pumps and air compressors stand out as the ideal pneumatic solution. The integration of these machines with various control systems and the latest communication protocols, like PLC, HMI and SCADA, further underline the advantages of Pneumofore. Hundreds of two-piece aluminium can factories already rely on our expertise, consistently choosing our Rotary Vane technology for its proven constant efficiency and durability.

Only a few can making companies have the necessary know-how in low-pressure compressor design. Factories located in hot climates or above 1,000 meters of altitude pose additional challenges, as these atmospheric conditions demand customized compressed air solutions with enlarged cooling systems to cope with ‘thin air’. For vacuum pumps, the required capacity often reaches several thousand cubic meters per hour and the entire vacuum system setup significantly impacts long-term efficiency. Therefore, with every sale of a large vacuum pump, Pneumofore offers a schematic installation drawing with pipeline diameters and definitions of vacuum accessories such as filters, valves and receivers.

Pneumofore enjoys a privileged position as one of the preferred suppliers of vacuum pumps and air compressors in the two-piece can industry, supported by extensive experience and strong references worldwide.

With a 10-year warranty on the efficiency of the UV Series vacuum pumps, Pneumofore sets the benchmark in industrial vacuum systems.

When low pressure compressed air at 3,5 bar(g) is required, 2-stage turbo compressors are sometimes used. However, they have limited adaptability to the everchanging needs of glass production. Moreover, the stoppage of a large turbo compressor can be very problematic due to the rare availability of backup units. Therefore, glassworks prefer centralised systems of mid-sized air compressors with few hundred kW. Pneumofore’s Rotary Vane air compressors equipped with Variable Speed drives precisely match the needs of glass bottle moulding at the IS machine. The line-filters used with these lubricated compressor systems purify the compressed air in order to achieve higher purity levels than oil-free compressors.

Hundreds of glassworks worldwide rely on Pneumofore’s vacuum pumps and compressors. Testimonials from satisfied customers consistently highlight the low operational costs, durability and constant efficiency of Pneumofore’s pneumatic systems, making them a trusted choice in the glass industry.

Vacuum pumps play a crucial role in electronics assembly, particularly in precision-driven ‘Pick & Place’ operations. Advanced vacuum systems manage the handling of delicate components and their safe packaging.

Traditionally, packaging machines and assembly stations were supplied by ‘on-board’ vacuum pumps, a decentralized option which may disturb the sterile environment of clean rooms and the human concentration with vibrations, contaminants, heat and noise.

Nowadays, the most efficient solution is represented by centralized vacuum systems connected to the assembly network. Sterile production rooms remain undisturbed, while maintenance procedures are strongly optimized. Instead of addressing on-board vacuum pumps individually, centralized vacuum systems undergo regular servicing and avoid production halts caused by unforeseen pump issues. Furthermore, having fewer high-performance vacuum pumps is the key to enhance reliability and energy efficiency.

With a track record of thousands of centralized vacuum systems running non-stop for decades, Pneumofore UV Series vacuum pumps offer high reliability and constant efficiency over the years. Based on Rotary Vane technology, Pneumofore machines eliminate the need of overhauls and are backed with an extended warranty, ensuring trouble-free operation with minimal maintenance requirements. With every UV Series installation, Pneumofore offers system engineering support with precise pipeline calculations in order to reduce any potential losses in pressure or capacity, resulting in further benefits in terms of power consumption, substantial cost savings, and significantly prolonged service intervals.

Pneumofore is dedicated to advancing processes for insulating electrical windings and capacitors in medium and high-voltage devices such as motors, transformers, and generators. One of the key technologies in this field is Vacuum Pressure Impregnation (VPI), which ensures perfect electrical insulation for high-voltage applications. This process is essential for both industrial-scale motor production and the fabrication of single, large-size transformers.

VPI offers numerous benefits, including the use of dielectric materials and special resins or oils. The process is cyclic, reaching during each cycle a low vacuum level, which is crucial for achieving a consistent and high-quality surface treatment throughout the year. Such performance is not possible with alternative vacuum solutions such as liquid ring vacuum pumps, as they depend strongly from the cooling water temperature,  varying consistently between Summer and Winter.

To optimize productivity, it is important to achieve high pumping speeds and low-pressure levels, especially depending on the reactor size. Pneumofore has established a strong track record in this area and is actively involved in projects aimed at vacuum centralization for multiple autoclaves.

The car industry is going green with electric vehicles. So do the tire manufacturers, under the pressure of environmental requirements. They select high quality vacuum pumps with top reliability and durability, with the lowest power consumption, for minimal emissions, over the long-term. This is how Pneumofore is getting involved more and more.

The production of tires relies on vacuum technology for several key operations: degassing in the rubber extruder, curing machines and pick & place. These three manufacturing steps are often separate. For optimal tire quality, vacuum application begins at the extruder stage to eliminate moisture, enhancing rubber quality. The pick & place operation using vacuum is straightforward, while the curing process is more complex. Vacuum can be applied to both the bladder and the tire mould. It is used to evacuate the bladder, facilitating the tire extraction from the mould, and is also applied within the mould for better shaping, removing any excess air from the mould, ensuring that the rubber compound is evenly distributed and that the tire takes on the desired shape.

Pneumofore has a long history of supplying vacuum pumps to the tire industry, dating back to 1961 with Michelin. Over the years, Pneumofore has developed skid-mounted solutions for Pirelli’s single lines and installed UV pumps for MRF in India and Nexen in Europe, among others.

Traditionally, drying processes have relied on heat, with techniques evolving from natural sun drying to advanced oven drying over the centuries. However, vacuum drying offers significant advantages by efficiently removing moisture without excessive energy consumption. This method is effective for materials such as wood, metal, pulp and paper, polymers, and more. Degassing with vacuum is applied in extruders for pasta dough, clay for bricks and tiles, and various other materials.

Vacuum drying must be applied gradually to materials like wood to prevent damage, whereas metals can be dried quickly and efficiently after washing, avoiding the higher energy consumption and potential deformation associated with heat drying. Pneumofore has developed the UV H pumps, where H stands for High temperature of the coolant, above 100°C, ensuring all evacuated water moisture is exhausted from the pump at the discharge.

Large-scale drying processes benefit greatly from vacuum drying, which reduces drying times and energy usage compared to conventional heat drying methods. For instance, metal parts that require drying after washing can be efficiently dried using vacuum technology, as demonstrated in the case study [Brakes India].

Polyester chips, resulting from polymerization, need low moisture content for high-quality yarn production. Low dew points, with minimal residual humidity, are achieved using a multi-stage vacuum system. This method ensures effective drying, crucial for their processing, as highlighted in the case study [Polyester Chips] in India.

In the food industry, vacuum is used in freeze-drying processes to extend the shelf life of fruits and vegetables by removing moisture content. Most Pneumofore installations in this sector are found in the USA.

Degassing applications include Italian pasta production, where vacuum is used in extruders to ensure a homogeneous mixture and prevent water-induced defects or flavor changes. Precise control of vacuum levels and flow rates is essential to maintain product quality. The drying of food is described in more detail in the dedicated [Pasta section], with a testimonial video from [Pasta Berruto] and several case studies.

[Food processing] with vacuum is also found in tumblers for softening red meat or in evisceration plants. Vacuum cooling is applied in the baking of bread (see the dedicated section). The [packaging of food], whether fish, meat, or other perishable items, utilizes vacuum to extract air and humidity, reducing potential deterioration by bacteria due to the absence of oxygen and water. In food packaging, vacuum is also used in bottling liquids like soda drinks or beer.

Pipeline drying after the dewatering process of new lines typically targets a dew point of -40°C, achieved with a double-stage vacuum system. Special UV H pumps are installed, combined with roots pumps as the second stage, to meet these requirements in the petrochemical industry. See the dedicated [Pipeline Drying section] in Applications with case studies.

The production of high-quality ceramics with high hardness and fine surface finish is supported by vacuum systems composed of two stages. Large-scale manufacturing of bricks and tiles uses vacuum to eliminate air and water presence at the extruder, allowing better quality of building parts and reducing the energy required by the oven. See the dedicated [Ceramics, Bricks & Tiles section].

Vacuum is applied for the evaporation of condensation accumulated during the storage and transportation of lubricants for industrial and automotive use (see the case study of [Petronas Lubricants]). Another process is Vapor Recovery for ships transporting crude oil and derivatives, which, after unloading, still contain considerable amounts of gas that, by law, cannot be emitted into the atmosphere. Vapor recovery units (VRUs) use Pneumofore vacuum pumps, ATEX certified, to evacuate explosive gases in large capacities.

For materials like leather and aggressive chemicals, vacuum systems need protective measures to prevent contamination. Pneumofore provides innovative vacuum solutions tailored to various industrial drying and degassing needs, ensuring efficient, energy-saving operations across different sectors.

The vacuum is created within the kneading machine, where wheat flour and precisely measured water are mixed to form a homogeneous dough. Prior to extrusion, which shapes the pasta into forms such as macaroni and penne, the dough undergoes partial drying through vacuum evaporation until it reaches a predetermined humidity level. The pasta is further dried in dryers down the production line.
This controlled humidity level facilitates the dough’s passage through the die, effectively eliminating ‘white spots,’ or micro air bubbles, that can compromise the pasta’s texture and its ‘al dente’ feature during cooking. Vacuum technology is used in pasta production for several reasons: improved pasta quality, shorter drying times, a homogeneous dough structure, and a natural colour due to reduced oxidation.
Pneumofore supplies UV H Series vacuum pumps to the pasta industry, primarily in Italy but also internationally. These pumps typically replace liquid ring vacuum pumps, eliminating the need for a cooling water circuit and towers, as well as halving electric power consumption. Special filters protect the pumps and food-grade coolant is used to meet the latest international food industry standards. These features are highly appreciated by pasta manufacturers who frequently return to Pneumofore for expansion projects.
Italian pasta is renowned worldwide for its quality and taste, a reputation strongly supported by the appropriate vacuum systems that Pneumofore has mastered for decades.

In the past, drying pipelines relied exclusively on liquid ring vacuum pumps. These pumps, which used water as a cooling liquid, were often inefficient due to their performance dependency on the temperature of the sealant. This posed significant challenges in extreme climates, where temperatures could be excessively high or fall below freezing, leading to low drying performance.
The complexity of the system, involving a generator, liquid ring vacuum pump, and cooling water tower, became even more complicated by the introduction of ultra-dry compressed air systems. These systems, while eliminating the need for water, required significantly higher energy due to their large compressors and multi-stage drying processes with chillers. In the end, in energy terms, they were worse than the liquid ring vacuum pumps.

In 2006, a significant development was achieved by Gazprom, the leading Russian company in the petrochemical sector. They implemented a pioneering solution by equipping a truck trailer with a generator and two Pneumofore UV50 H vacuum pumps. This innovation created a fully air-cooled vacuum system, based on the superior performance of UV H pumps in removing large quantities of water vapor. One UV50 H vacuum pump evacuates up to 214 kg/h of water.
Drying speed was further enhanced by adding additional roots stages to the UV H backing pumps, a technique also adopted by BJ Services and Trans-Asia Pipeline Services. This advancement marked an important improvement in pipeline drying times. Returning customers appreciate Pneumofore’s ready-to-use, mobile vacuum drying systems, ensuring fast, more cost-effective, and energy-efficient pipeline drying solutions, successfully applied after hydrotesting.

Pneumatic conveying is an efficient and versatile method used for transporting bulk materials through a pipeline using air. The size and weight of the grains sometimes require a higher vacuum level than what Side Channel Blowers can achieve. Maintaining the exact vacuum is crucial for accurate dosing, particularly in industries where precision and uniformity are critical.
A wide range of materials can be moved using pneumatic conveying, each with unique characteristics that must be considered to ensure optimal system design and operation. For example, cement differs significantly from polymer granulate or cereals in terms of specific weight, fragility, and hardness. These differences necessitate careful calculation of pipe sizes and materials to accommodate the unique requirements of each material.
When transporting materials with vacuum rather than pressure, there is an inherent risk of contaminating the vacuum pumps with the conveyed material. This potential contamination can compromise the efficiency and longevity of the pumps. Therefore, it is essential to implement tailored filtration systems to protect the pumps. These filtration systems are designed to capture and remove any particulates or contaminants from the material stream before they can enter the pump, ensuring the system remains clean and operates effectively.
Additionally, pneumatic conveying systems must be designed to handle the specific challenges posed by different materials. For example, fragile materials require gentle handling to prevent damage, while abrasive materials need robust pipelines and components to withstand wear. The system design also includes considerations for maintaining the integrity of the conveyed material, preventing segregation, and minimizing degradation.
In conclusion, pneumatic conveying is a highly adaptable solution for transporting a variety of materials. However, it requires careful planning and design to address the unique properties of each material and to protect the conveying equipment. With the right approach, pneumatic conveying systems can offer reliable and efficient material handling for a wide range of applications.
