Air compressors for the paper industry

Maximum energy efficiency, reliability and low maintenance make Mattei vane compressors the best choice for the paper industry.

How to choose your compressor

Choosing an air compressor must hinge on the specific production and environmental characteristics of this industry.

Compressed air in the paper industry

In the production of paper and cardboard, compressed air is transversally involved in the operation of the machinery used in the production processes, so much so that the compressor room is included within the “auxiliary services” in the classification of energy utilities, together with the thermal power station, the refrigeration plant, the waste treatment and more.

Paper and cardboard production process is complex and varies according to the type of pulp used and the finished product (paper-transformation industry products, corrugated cardboard, hygiene products). Schematically, the process can be divided into three main phases

  1. preparation of the pulp; 
  2. manufacturing of the sheet; 
  3. surface treatments and final preparation.

The core of this cycle is the manufacturing of the sheet, which takes place through the so-called “continuous paper machine”, so called because the sheet of paper is generated linearly and without interruption. During this step, in which the compressors are also activated, paper is formed and dried, first through presses, then through hot air. Other important operations that involve air blowing are also carried out in paper mills, such as machinery cleaning.

Energy efficiency and recovery

The paper industry is one of the most energy-intensive sectors, characterised by a high need for electrical and thermal energy per unit of product: energy costs can exceed 20% of total production costs. Therefore, reducing energy needs is crucial for paper mills in order to remain competitive in the market.

 

 

 

Among the interventions that energy managers can evaluate to reduce consumption and costs associated with electricity is the installation of high efficiency compressors equipped with inverters. Mattei compressors fit perfectly into a process of energy efficiency and improvement of environmental sustainability parameters of paper mills: thanks to the innovative vane construction technology, in fact, these machines allow saving 15% on electricity consumption compared to a rotary screw compressor and boast the lowest Life Cycle Cost on the market. In addition, the heat recovery system, which can be installed on many Mattei compressors, allows recovering 80% of the thermal energy generated during operation, and reusing it for other processes.

Operational reliability and continuity

Since paper production is based on machines that work in a continuous cycle, compressed air must be supplied constantly over time. It is therefore necessary to be able to rely on air compressors that guarantee operation without downtime or loss of performance.

The reliability of Mattei compressors, obtained thanks to the quality of the materials and the particular construction design that minimises component wear, allows obtaining constant performance for over 100,000 hours of operation without the need to replace mechanical parts or make significant overhauls. Mattei control and management systems also ensure that the compressor room operates in the most efficient way, always maintaining the supply of compressed air adequate to the demand of the production process.

The benefits of Mattei compressors for the paper industry

Mattei compressors offer quality and performance characteristics suitable for the continuous supply of compressed air in the paper industry: 

  • greater energy efficiency thanks to the vane technology that allows energy savings up to 15% and higher environment standards compared to other rotary compressors;
  • maximum operational continuity and reduced maintenance costs thanks to the construction design that minimises wear and reduces the interventions for component replacement;
  • heat recovery system that allows up to 80% of the heat energy generated during compressor operation to be reused;
  • wide and versatile range to meet the most diverse compressed air requests;
  • supervision and management systems that allow for a more effective energy and cost-efficient configuration of the compressor room;
  • compressed air free from impurities thanks to a system that separates the oil from the air in different stages and an efficient filtering system, ideal for critical processes that affect the quality of the finished product;
  • possibility to create customised solutions, for specific applications or particular environmental conditions.
