The new Mattei 4000 Series, with installed power levels from 55 to 90 kw, ensures quality and reliable compressed air even for prolonged use: designed for continuous industrial use 24/7, the units use Mattei rotary vane technology, which translates into high performances, low energy consumption, and simple, economic maintenance.
The iron vanes and other compressor moving parts run slowly and without friction on a layer of oil and have a practically unlimited product life. The electric motor, which turns at a speed of only 1500 rpm (1000 in the Maxima model), is directly coupled with the pump group by an elastic coupling. The direct coupling ensures further savings, as no energy is wasted by gears or trapezoidal belts, nor are there maintenance costs for replacing bearings.
The large-size filter system allows quality compressed air to be obtained for any application. The special oil separation on several levels ensures that the filter elements are long-lasting, allowing extremely low oil consumption and carry-over. In addition, compressed air completely free of impurities, ideal for all food grade applications, can be obtained by installing a Mattei drying and filtration system on the main plant unit.
Furthermore, the non-toxic synthetic Mattei Food Grade lubricant, approved by the USDA for use in the food and beverage industry, was recently reformulated to guarantee longer working life, while extending replacement intervals.
The soft-start function ensures easy and gradual machine start-up, without which the components of the compressor unit and coupling are overloaded by the starting of the electric motor.
The latter derives particular benefit as the absorbed current peaks and initial loads on the bearings are limited.
The new 4000 Series is extremely silent, due to its new noise shielding system and a different routing of the intake air for cooling.
Routine maintenance is limited to changing oil and cleaning or replacing the various filters. It is particularly simplified owing to the accessibility of the internal components with the functional opening of the body panelling; the pre-filters for the cooling air can be accessed externally and can be inspected and replaced immediately.
Many food sector industries have chosen the 4000 Series Maxima 75 model, the Mattei compressor designed to guarantee enhanced productivity in operating conditions which require a constant air supply for prolonged periods.
Maxima 75 is a 75 kW unit with a capacity of 15.93 m3/min, and features a pump unit with a low rotation speed (1,000 rpm) and reduced acoustic impact.
It is equipped with the exclusive Maestro XS electronic controller which monitors and programs the compressor functions, whilst the cooling system can be adjusted to suit the capacity and environmental conditions.
Maxima is the first single-stage compressor with an energy efficiency equal to that of the two-stage compressors found on the market. The secret behind such extraordinary efficiency is our ongoing technological research that has allowed us to achieve an exceptional result of 5.4 kW/m3/min.
To further increase energy savings, it is possible to install a heat recovery kit that allows you to reuse the thermal power produced during the compression phase to heat water destined for industrial or domestic use. The range of accessories also includes a water-oil separator kit and a condensate separator and discharger kit.
Maxima also comes in a totally water cooled version and with an integrated air dryer unit.
