AIR CENTRE About Us Ing. Enea Mattei SpA is an Italian company that has been producing air compressors since 1919. Over the years, the company has continually evolved and is today one of the world’s foremost companies in the compressed air sector and the leader in the production of rotary vane compressors. Behind the success of Mattei are the choices the company has made in terms of design, production and marketing, driven by the results of its continual and in-depth research and devlopment programmes. During these years of continual change, Mattei has been able to adapt to the requirements...

Simply different The compressor that makes a difference MATTEI’S COMPRESSORS Mattei’s rotary vane air compressors are the result of continuous innovation and advanced design capabilities. The low rotational speed of the compressor unit found only in vane technology, the high volumetric efficiency and the complete absence of roller or thrust bearings, result in energy savings of over 15% compared to other rotary compressors. EFFICIENCY 1:1 All Mattei’s compressors have a 1:1 ratio between the electric motor speed and that of the airend. This means greater energy efficiency and higher...

AIR CENTRE Series Air Centre Rotary Vane Compressors Mattei’s Air Centre series compressors are complete and efficient machines that are ideal for any type of industrial application. DIRECT COUPLING Mattei has always produced compressors in which the electric motor, which turns at a speed of only 1,500 rpm, is directly coupled to the compression unit by means of a flexible joint. This direct, in-line coupling results in considerable energy saving as there are no losses due to the presence of pulley wheels and drive belts. AUTOMATIC FLOW RATE CONTROL As well as the classic “ON/OFF OPERATION”...

Operating principle PRESSION COM Maximum efficiency of the air compression process, excellent reliability and low running costs; are just some of the key benefits that rotary vane technology can offer. The vane compressor is a volumetric rotary compressor that consists of a stator cylinder in which a rotor is mounted off-centre but parallel to its sides. The rotor has slots in which the vanes are free to slide: centrifugal force keeps them in contact with the sides of the stator during rotation. The rotary vane compressor, thanks to its simple construction, offers remarkable advantages,...

CONTROLLERS MAESTROXS to have everything under control With a view to energy saving, the communication inside a compressor room plays a decisive role. It is absolutely essential to manage, control and immediately intervene in the operation of the system in order to prevent waste and unnecessary energy consumption. For this reason, all of Mattei’s Air Centre compressors are fitted as standard with a microprocessor command and control device: MaestroXS. Microprocessor control system MaestroXS is programmable controller, which regulate the compressor’s operation and adapt this to the specific...

MAESTROxs: features and functions • Ergonomic control panel with quick access keys to main menus. • Menus access keys, start, stop and reset led keys. • Semi-graphic LCD display with illuminated text. • 24 Vdc digital inputs. • Digital dry contacts output up to 230 Vac and up to 24 Vdc. • Interfaces: RS485 for intercommunication with other MAESTRO devices. RS485 (optional) to communicate with the supervising PC and network. • Analogue data display (line pressure, chamber pressure, oil temperature, outgoing air temperature) and general data (alarms, operating messages, machine state, maximum...

CONTROLLERS CONCERTO: Complete control and absolute flexibility Numerous compressor stops and starts, energy wastage and wide variations in the compressor operation represent common problems in many compressed air systems. Concerto is Mattei’s state-of-the-art compressed air management system, designed to satisfy any requirement of a compressed air user, regardless of the type of compressor installed. By the use of customisable functions the device allows the simultaneous command and control of up to 16 compressors, maintains a tight energy-saving pressure dead-band, limiting the idle...

QUARTETTO When a production process requires variable amounts of compressed air or it is necessary to avoid any machine downtime, a controller optimises the compressed air system management. Quartetto, obtained through a programmable controller, can control operation of more compressors, up to max. 4 units, provided these are arranged with a remote start-stop control. It is not essential to drive exclusively Mattei compressors. Quartetto can meet the line air demand and the working load for each compressor in the most efficient way and reducing the energy absorption. OPERATING MODE •...

AIR CENTRE Energy recovery from compressed air In a lubricated and air-cooled compressor, about 80% of its absorbed power is wasted as heat in the oil. The heat absorbed by the oil during the air compression process is transferred to the air flow, that goes through the cooler and is dispersed to the atmosphere. The mechanical energy used for compression is wasted as follows: • about 80% for oil cooling; • about 10-12% transferred to the compressed air as heat; • about 2-3% in compressed air as energy; • the rest due to heat radiation. Mattei offers for its compressors a heat recovery system...
