Rotary vane compressors manufactured by Ing. Enea Mattei Spa will take the spotlight at Autopromotec 2015, the automotive tool and After market expo held every two years, in Bologna from May 20 - 24, 2015.
New items will be on display in Hall 30 stand B52.
It begins with the renovated Blade series, conceived to meet the needs of small companies and workshops. Mattei has designed and will soon launch exciting new additions to the range on the market to provide tailor made solutions for various industrial and service needs. The Blade versions with 1.5, 2.2 and 3kW power were designed for smaller workshops: characterised by an attractive design and minimal dimensions, they guarantee the quality and performance of industrial compressors. Along with these, the new models with 15, 18,5 and 22 kW power, intended for medium-sized companies, with excellent performance in terms of reliability, energy savings and reduced maintenance costs.
Mattei will also present the results achieved through partnerships with some iconic metalworking companies.
“We carefully selected the best Italian vacuum pump, booster and blower machine manufacturers, and sealed partnerships with the three companies marked by excellence, involving them in a project that will lead them to develop a series of products for Mattei – explained Giulio Contaldi, Ing. Enea Mattei SpA Managing Director – The ambitious goal is to consolidate our market share, relying on Made in Italy excellence”.
Side channel blowers
A specific series of directly activated blowers was developed for Mattei, equipped with input and output silencers and dynamically balanced aluminium alloy impellers. They are turbo machines that do not require lubrication or maintenance. They consist in an impeller that rotates inside a casing which has a peripheral toroidal channel, without sliding contacts with the surrounding parts. The fluid is propelled along circular trajectories between the impeller and the side channel; it is moved by the vanes from the input to the output zone of the machine, creating pressure and vacuum. Side channel blowers are used in many different industries: ceramics and glass, environmental and energy, wood processing and plastics, textiles and food processing, mechanics and the graphic and paper industry. In addition to the industrial cleaning, chemical-pharmaceutical and medical, electronics and packaging sectors. The direct-drive blower designed for Mattei includes single impeller/single stage, single impeller/ dual stage and dual impeller / dual stage devices.
Lubricated vane vacuum pumps
Lubricated vane vacuum pumps are used when the suctioned flow may contain moisture or when improved final pressure is required and particularly in demand in industries such as vacuum packaging, thermoforming machines, machines for the processing of glass or marble, medical equipment and food-grade pasta or clay extruders. Also in this case, Mattei had a wide range of pumps developed that are characterised by their reduced size, low noise level and the simplicity of the inspection and servicing operations. They are equipped with a damping and recovery system featuring a by-pass, combined with the new oil recovery float valve, which guarantees the absence of discharged oil vapours and has a sealing device that prevents the oil from resurfacing if the pump stops in vacuum mode; these pumps are suitable for continuous suction within a pressure range of from 400 to 0.1 mbar.
High pressure and oil free boosters
Compressors and oil-free boosters provide compressed air without oily residue, specifically indicated for many applications in the food, chemical, communications, electronics, pharmaceutical, photography, technical gas, naval and plastic industries. The series of machines developed Mattei - with capacities up to 1250 m3/h and pressures up to 45 bar - are available in the compressor version (suction at atmospheric pressure) and in the booster version (suction at a pressure of 6-8 bar) and are used for technical gases such as air, nitrogen, carbon dioxide, nitrous oxide, argon and other mixtures. In addition to the above, Mattei also commissioned a complete range of alternative high pressure boosters, that compress the air taken at 6-8 bar from the standard network to a pressure of up to 40 bars. In their single-stage version, with air-cooled cylinders and low rpm, these booster compressors are used in the blowing of PET plastic containers, in drive systems for presses, hydraulic and pneumatic cylinders and testing of pressurised vessels and heat exchangers. Their extremely compact dimensions are complemented by the low installed power and low energy consumptions.
On the reasons that led to this project, Contaldi concludes: "Our company has always believed in the value of a production that is 100% Made in Italy, striving to be recognised for the values that have always been the strong point of our manufacturing industry. This is why we have always refused the easy short cuts that others have sometimes taken, investing in people and technology and developing our own know-how, completely original, that the market has proved to appreciate. Now, thanks to this project, we intend to embark on the next step of this journey”.
