Mattei Optima Air Compressors
11 kW thru 200 kW Cabinet VSD Air Compressors
The Best Solution for Savings 68 through 1,254 SCFM:
Available in 460v/3Ph/60Hz.
Optima Series leverages the superior mechanical efficiencies engineered into Mattei’s rotary vane technology to lower your operating costs, particularly when compared to typical rotary screw air compressors. Benefit from sophisticated high-efficiency performance, quiet dependable operation and low maintenance. Featuring quiet (as low as 65 dB(A)) cabinet enclosures, electronic controllers, energy saving soft-starting AC inverter drives, premium efficiency TEFC motors, air-cooled aftercoolers and optional integrated refrigerated air dryers, to deliver unbeatable performance and energy savings across the entire range of variable air demands.
Turn Up the Savings
Don’t get caught up in the hype the rotary screw air compressor folks refer to in who’s got the better “turn down” ratios for VSD type air compressors. Every airend technology has an ideal speed range for best efficiency and performance. Rotary screw airends are very sensitive to variations in speed. Turn them too fast or too slow and the efficiency drops off significantly. Whereas, Mattei’s rotary vane airends never run too fast and deliver better energy efficiencies as they slow down, which lets you turn up your savings through lower operating costs at comparable flow rates.
How Can This Be?
Simple. Mattei’s rotary vane airend technology uses very little lubricant in the compression process to deliver ~90% mechanical efficiency air production, whose efficiency does not deteriorate as it slows down in speed.
Conversely, rotary screw airend technology uses a lot of fluid to compress the air and delivers much lower mechanical efficiencies. Much like blowing through a straw into a glass, the air bubbles up through the oil and flows along the “blow hole” recirculating back to the suction side due to the high differential pressures along the length of the screws. Thus, rotary screw inefficiencies become more evident as speed increases, but more so as it slows down.
For example, say you need about 30 HP worth of air for a period of time and you have a 100 HP VSD type rotary screw air compressor. The performance curve shows higher kW/100 cfm requirements as the machine slows down in essence costing you 40 HP worth of energy to gain 30 HP worth of air. On the other hand, our Optima will reach minimum speed and begin to operate load/off load saving you significant power. That’s why we say, “Don’t let the rotary screw boys throw you a curve in saving energy.”
Save Energy, Save the Environment
Mattei compressors are not only friendly to your wallet, but the environment as well. Each unit holds very little lubricant (typically less than half that of a rotary screw air compressor) which saves you a small fortune on oil changes and disposal costs. The oil filter is cleanable through most models; yes, cleanable. The highly efficient mechanical air/oil separation chamber delivers high quality air to the air/oil separator filter thus, it sees very little lubricant and provides up to 10,000 hours of service, and low 1-3 ppm oil carryover.
OPTIMA SERIES STANDARD FEATURES:
CONDENSATE DRAIN AND SEPARATOR KIT
The kit includes a condensate separator and a timed electronic drain.
Optima was designed to offer the best performances in every operating condition. The exclusive technology of the compression unit guarantees the best volumetric performances across the range of air demand, and some of
the lowest kW/100 CFM performance in the industry
MATTEI INVERTER REGULATION SYSTEM
The Mattei inverter system always assures the highest energy savings. When the compressed air demand is between 100% and 40%, the compressor rotational speed reaches the highest efficiency, with an energy consumption much lower than traditional inverter systems
These compressors are designed for industrial use 24 hours a day and 12 months a year at constant pressure. Mattei compressors' running often exceeds 100,000 working hours, as evidenced by our revolutionary 10-year warranty.
Optima Series compressors are cabinet enclosed machines that operate at a constant 1,800 rpm and deliver sound levels as low as 65 dB(A).
Much like the connecting rods on your engines crankshaft, the heart of the Mattei rotor stator unit (RSU) is the rotor which is simply supported by two (2) white metal Babbitt bushings that routinely deliver >100,000 hours of life. Screw-type compressors use up to six (6) radial and thrust bearings engineered for only 50,000 hours (ASME B-10) of life.
Optima compressors are silent, and are equipped with an elastic coupling between motor and compressor, without gears, belts to be changed or adjusted, nor ball bearings to be maintained.
PREMIIUM EFFICIENCY MOTOR
Premium efficiency totally enclosed fan cooled (TEFC) electric motors is standard on Optima Series.
The exclusive three-stage oil separating system guarantees a maximum oil carry-over in the air lower than 3 ppm. Moreover, the air cooled aftercooler ensure approach temperatures of 18°F or less.
Air cooled aftercooler with 18°F approach temperature. Moisture separator with automatic drain valve is optional on Optima Series.
Maintenance operations only include changing the oil at predetermined intervals, cleaning or replacing the air filter and cleaning the radiator. Benefit from half the oil volume of rotary screw types, and oil separating filters that
can reach 10,000 working hours, for significant savings over the life of the machine.
AUTOMATIC ON LOAD / OFF LOAD
Should pressure continue to rise upon reaching minimum speed, Optima automatically engages Load/Off Load control to maintain line pressure within a minimum/maximum pressure range, and the compressor may stop and
restart according to air demand.
Optima is equipped with an exclusive state-of-the art computerized controller, Maestro XS
Maestro XS, automatically controls, monitors and programs the unit's operation, and has an option to connect to a PC for a remote control. If connected to other compressed air packages equipped with Maestro XS, the unit
can become master of a compressed air plant, thus saving on the installation of a superior controller. Maestro XS can be interfaced via web or cellular technology to provide remote service monitoring.
