    With the introduction of the latest models to the ALTA-TEC series, Pilot Air is once more redefining the standards in respect to efficiency, reliability and energy savings.

    The continuous investment in Research & Development has allowed the further improvement to the acclaimed ALTA-TEC series, already a leading-edge product in the industrial market, by introducing Permanent Magnet Motors (with IE4 Efficiency class – Super Premium Efficiency). This is combined with our direct transmission system and optimised controls in the form of the new and highly advanced Login electronic controller.

    These new and innovative technologies, combined with the employment of our latest generation air-ends, has allowed us to build the most advanced, quiet, reliable and efficient compressor available.

    The inverter, pre-installed in the compressor’s electrical panel, dynamically regulates the speed of the electric motor and therefore the speed of the air-end, continuously adjusting the delivered air flow to the system’s real time compressed air requirements. This also eliminates current surges thanks to the soft start-up and drastically reduces operating cycles avoiding unnecessary no-load operation, avoiding significant energy wastage and reducing energy costs.

    When compared to the operation of a fixed speed compressor, an ALTA-TEC is able to achieve significant energy savings, up to 50%.

    This represents a reduction of around 30% to the total life cycle costs during years of use.

    The calculation shown in the graphs is based on the energy analysis of a 37 kW ALTA-TEC, considering 4000 working hours per year and an energy cost of about .25c kWh.

    For all companies, environmental sustainability is a most important objective and why a focus on the efficiency of all processes is critical. ALTA-TEC compressors provide a significant opportunity in this area.

    Working and living sustainably means preserving our natural resources as much as possible: choosing an ALTA-TEC product, reducing energy consumption and CO2 emissions therefore, represents an ecological and sensible choice.

    The direct coupled transmission ensures maximum efficiency, quieter operation and less maintenance than similar belt driven designs.

    The advanced and extremely compact Permanent Magnet motors, guarantee the highest performance along with a much wider speed/load range when compared to traditional inverter-controlled asynchronous motors.

    They offer the greatest possible advantages in terms of energy savings. This applies especially when used at partial capacity and load, which is a characteristic seen frequently in modern applications throughout all industrial sectors.

    The new ‘Login’ controller introduces new software capabilities to strengthen diagnostic functions, thereby guaranteeing excellent performance in all conditions. Login provides additional facilities including remote control and multi-compressor management.

    All of K-MAX’s functions are entirely managed by the centralised Login electronic controller, which constantly monitors the compressors operation ensuring efficient and reliable operation of the machine in all conditions with customised functions to suit any application.

    During an irregular event within the machine, Login reports the presence of such and incident by creating an alert for the user, allowing for prompt operator intervention.

    The integrated connectivity with remote monitoring (optional), makes it possible to obtain complete information on the compressor status remotely.

    Thanks to the “ISC” system it is possible to simultaneously connect up to 8 different compressors (fixed and/or variable speed combinations), with “master-slave” logic. The system can also be used with other compressors not equipped with Login by using the optional modules suitable for specific compressors.

    The Pilot ALTA-TEC Industrial 22 Variable Speed Rotary Screw air compressor features remote monitoring (on demand) – via GSM, GPRS, Ethernet or WiFi module – for online compressor status, remote assistance, connection with PC, smartphone and tablet, and connection between neighbour compressors. The optional Service Management System (SMS 2.0) device allows operators and service centres to remotely control and perform preventive maintenance checks on screw compressors equipped with ETIV controller. These facilities are provided when the device is configured for local internet network via Wi-Fi or Ethernet connectivity. The SMS system allows for emails to be sent automatically in the case of a fault or other anomalies and/or for automatic regular emails (hourly, daily or weekly) to be sent to monitor the proper operation of the compressor and to define the remaining hours for service. Other information and settings can be accessed remotely aimed at safeguarding the reliability of the system.

    The LOGIN advanced electronic controllers include:

    • Working pressure (offload/load)
    • Oil temperature
    • Compressor status (stand-by, offload, load)
    • Fan status (off/on)
    • Date and time
