We offer complete solutions to your business from quality machines to service options that will keep your air compressor running. We believe improvement never stops and ensure that our products and service reflect this.   Discover the Technology behind Evoluto! ## The Evoluto iPM Drivetrain technology The drivetrain in our Evoluto range of compressors is an incredible feat of engineering. A drivetrain consists of 3 key parts, and we made improvements on every one of them. It features an oil-cooled interior permanent magnet motor, an integrated direct drive transmission, and our new screw element. These three innovations have a major impact on the compressor's overall efficiency, reliability, and productivity. Let's take a closer look at how they are improved. ## Improved energy efficiency saves you money • In-house designed iPM motor (1) with IE4 Super Premium Efficiency• New generation in-house designed screw elements (2) with improved efficiency• Integrated direct drive transmission (3) for minimal losses• Smart inlet valve (5) optimizes the inlet flow and improves efficiency ## Increased reliability extends lifetime • iPM motor (1) rated IP66, protected against dust and water ingress• Globally renowned screw elements (2), proven in thousands of installations• Optimal cooling at all speeds and conditions thanks to the oil-cooling principle (4) of the iPM motor (1) Maintenance-free design minimizes downtime and improves your productivity • No greasing of the motor (1) bearing needed• Coupling-free direct drive design (3), no maintenance needed• Smart inlet valve (5), no maintenance needed ## 1. The Interior Permanent Magnet Motor The first big impact on the Evoluto's efficiency comes from our in-house designed iPM motor which is rated at IE4 Super Premium Efficiency according to IEC 60034-30, a standard on efficiency classes for low voltage AC motors. Compared to conventional induction motors, our iPM motor benefits from significant energy savings thanks to lower heat losses and by completely avoiding slip losses. In terms of protection, the motor itself is IP66 rated (protected against dust and multi-directional, high-pressure water jets). The iPM motor is located on the right side of the compressor drivetrain.In a conventional induction motor, an electric current flowing in the stator windings in a rotating motion will, thanks to electromagnetism, create a rotating magnetic field (RMF) in the stator. The RMF rotates at synchronous speed. Through electromagnetic induction, the RMF also induces an electric current and a magnetic field in the rotor. This magnetic field in the rotor will try to catch up to with the RMF of the stator but will always be behind in speed. In other words, the rotor rotates at asynchronous speed. The differences between synchronous and asynchronous speed are called slip losses and reduce the efficiency of the motor. Because current is induced in the rotor to create the rotor's magnetic field, the heat losses are rather high which further reduces the efficiency of the motor.In our iPM motor, permanent magnets are housed inside the rotor. When the electric current is flowing in the stator windings they create a rotating magnetic field (RMF). As a result, the permanent magnets inside of the rotor will be attracted by, and start rotating with the RMF of the stator. The rotor will rotate at the same exact speed as the RMF of the stator at synchronous speed, meaning there are no slip losses. The heat losses are also lower than those in conventional induction motors since no current needs to be induced in the rotor (the magnetic field of the rotor is created by the permanent magnets inside of the rotor).## 2. The Screw Element Another innovation is our new and latest generation of screw elements. Our globally renowned screw elements are designed and produced in-house in Belgium. By improving the rotor profile and reducing the pressure losses and leakages we were able to increase Free Air Delivery (FAD) while at the same time reducing the Specific Energy Requirement (SER) which means that we can deliver more compressed air while consuming less energy. ## 3. The Integrated Direct Drive Transmission The third improvement comes in the form of an integrated direct drive transmission, which means that the motor and screw element rotate together as one functional unit, resulting in zero transmission losses. Unlike conventional direct drive transmissions, this design is coupling-free, keeping transmission losses and service costs to a minimum. ## 4. The Oil-cooled Motor Housing Unlike a conventional air-cooled induction motor, our iPM motor is oil-cooled which assures optimal cooling at all speeds and conditions, increasing the reliability and motor lifetime.  Oil is injected in the motor housing and runs through canals around the motor, cooling it evenly. The oil then continues to the screw element where it lubricates and cools the rotors. This process is repeated over and over. If the oil gets too hot, it runs through the oil-cooler first before returning back to the motor. The benefits of the oil-cooling principle are clear, especially at lower motor speeds\/loads. When variable speed compressors regulate the motor speed to match the air supply to the air demand, two things happen in a conventional induction motor: Firstly, the motor generates more losses as the efficiency of the motor drops resulting in higher motor temperatures. Secondly, the speed of the motor cooling fan is reduced which reduces cooling capacity and further increases motor temperature. Higher motor temperatures reduce motor lifetime and can, in the worst case, result in a total failure of the motor. However, our oil-cooled iPM motor acts differently when operating at lower speeds\/loads. It generates fewer losses as the iPM motor technology is able to maintain its' high efficiency even at lower speeds\/loads. Secondly, as the cooling is independent of a motor cooling fan, optimal cooling is assured even at low speeds\/loads. Overall, this results in lower motor temperatures at all speeds and conditions, which extends motor lifetime and reliability. The cool oil runs through the housing, cooling the motor evenly.", "product_order": "0", "product_icon": "\/media\/commerce_products\/44\/ALUP_Evoluto-55_pack-front-no-model-number.png", "product_brand_id": "1", "product_price": "0.0000", "product_price_ex_tax": 0, "product_price_local_tax": "0.0000", "product_created_datetime": "2020-02-14 09:45:29", "product_code": "Evoluto 75", "product_barcode": null, "product_is_unorderable": "0", "product_is_shipping_required": "1", "product_inventory_level": null, "product_uri": "\/products\/rotary-screw-air-compressors\/above-50hp\/alup-evoluto-75-variable-speed-drive\/" }, { "product_id": "43", "product_title": "ALUP Evoluto 55 Oil Injected Screw Compressor with Variable Speed Drive", "product_content": "## Evolving Energy Efficiency Continuous investment in product development has resulted in our most innovative and energy efficient compressor to date.

The iPM motor is located on the right side of the compressor drivetrain.In a conventional induction motor, an electric current flowing in the stator windings in a rotating motion will, thanks to electromagnetism, create a rotating magnetic field (RMF) in the stator. The RMF rotates at synchronous speed. Through electromagnetic induction, the RMF also induces an electric current and a magnetic field in the rotor. This magnetic field in the rotor will try to catch up to with the RMF of the stator but will always be behind in speed. In other words, the rotor rotates at asynchronous speed. The differences between synchronous and asynchronous speed are called slip losses and reduce the efficiency of the motor. Because current is induced in the rotor to create the rotor's magnetic field, the heat losses are rather high which further reduces the efficiency of the motor.In our iPM motor, permanent magnets are housed inside the rotor. When the electric current is flowing in the stator windings they create a rotating magnetic field (RMF). As a result, the permanent magnets inside of the rotor will be attracted by, and start rotating with the RMF of the stator. The rotor will rotate at the same exact speed as the RMF of the stator at synchronous speed, meaning there are no slip losses. The heat losses are also lower than those in conventional induction motors since no current needs to be induced in the rotor (the magnetic field of the rotor is created by the permanent magnets inside of the rotor).## 2. The Screw Element Another innovation is our new and latest generation of screw elements. Our globally renowned screw elements are designed and produced in-house in Belgium. By improving the rotor profile and reducing the pressure losses and leakages we were able to increase Free Air Delivery (FAD) while at the same time reducing the Specific Energy Requirement (SER) which means that we can deliver more compressed air while consuming less energy. ## 3. The Integrated Direct Drive Transmission The third improvement comes in the form of an integrated direct drive transmission, which means that the motor and screw element rotate together as one functional unit, resulting in zero transmission losses. Unlike conventional direct drive transmissions, this design is coupling-free, keeping transmission losses and service costs to a minimum. ## 4. The Oil-cooled Motor Housing Unlike a conventional air-cooled induction motor, our iPM motor is oil-cooled which assures optimal cooling at all speeds and conditions, increasing the reliability and motor lifetime.  Oil is injected in the motor housing and runs through canals around the motor, cooling it evenly. The oil then continues to the screw element where it lubricates and cools the rotors. This process is repeated over and over. If the oil gets too hot, it runs through the oil-cooler first before returning back to the motor. The benefits of the oil-cooling principle are clear, especially at lower motor speeds\/loads. When variable speed compressors regulate the motor speed to match the air supply to the air demand, two things happen in a conventional induction motor: Firstly, the motor generates more losses as the efficiency of the motor drops resulting in higher motor temperatures. Secondly, the speed of the motor cooling fan is reduced which reduces cooling capacity and further increases motor temperature. Higher motor temperatures reduce motor lifetime and can, in the worst case, result in a total failure of the motor. However, our oil-cooled iPM motor acts differently when operating at lower speeds\/loads. It generates fewer losses as the iPM motor technology is able to maintain its' high efficiency even at lower speeds\/loads. Secondly, as the cooling is independent of a motor cooling fan, optimal cooling is assured even at low speeds\/loads. Overall, this results in lower motor temperatures at all speeds and conditions, which extends motor lifetime and reliability. The cool oil runs through the housing, cooling the motor evenly.", "product_order": "0", "product_icon": "\/media\/commerce_products\/43\/ALUP_Evoluto-55_ghost-pack-L_out.jpg", "product_brand_id": "1", "product_price": "0.0000", "product_price_ex_tax": 0, "product_price_local_tax": "0.0000", "product_created_datetime": "2020-02-14 09:45:27", "product_code": "Evoluto 55", "product_barcode": null, "product_is_unorderable": "0", "product_is_shipping_required": "1", "product_inventory_level": null, "product_uri": "\/products\/rotary-screw-air-compressors\/above-50hp\/alup-evoluto-55-variable-speed-drive\/" }, { "product_id": "42", "product_title": "ALUP Evoluto 45 Screw Compressor with Variable Speed Drive!

Leasing a Nitrogen Generator on-site from Ash Air is a risk-free way for you to cover your Nitrogen needs (up to 99.999% purity, up to 148 m3\/h flow) The On-Site Nitrogen Generation package will includes compressor, filtration, receivers, PPNG Nitrogen Generator and piping system. Leasing an Nitrogen Generator on-site is a risk free alternative to liquid nitrogen: all you need is to provide electricity and space. If you opt for a lease, you incur no capital expenditure; you simply switch from MANPAK to your own Nitrogen lease fee. The fee is fixed for 5 years, thus nitrogen costs will remain as your operating expenses. We will do remote monitoring and preventative maintenance to ensure the highest up-time. The PPNG series is Pneumatech’s premium on-site nitrogen solution for low to high flows, with best-in-class performance and the most complete scope of supply.The generator has outstanding air factors at full load thanks to the use of highly efficient Carbon Molecular Sieves (CMS) and back-flow pressurization.The air consumption is also optimized at reduced nitrogen flow or pressure demands, thanks to the advanced energy saving algorithm, which automatically adjusts the cycle times of the generator.The control and monitoring capabilities of the PPNG series are truly impressive. Purity is guaranteed at all times by opening the consumer valve only at the requested purity level and flushing nitrogen when purity is not reached. Feed air quality is controlled by monitoring the critical parameters i.e Temperature, Pressure and Dew Point. CMS is prone to the damages when exposed to water and oil. All risks of possible CMS damages due to high humidity and higher velocities are eliminated thanks to the inlet dew point control and Automatic start up feature of PPNG HE. ## Benefits of On-Site Nitrogen Generation: Less cost per m3\/min No hidden cost such as MANPAK rent and transport NO cost of evaporated nor remaining nitrogen in bottles Operating cost only (lease or lease-to-own solutions) PPNG Nitrogen Generators use Pressure Swing Adsorption technology to extract nitrogen molecules from the compressed air; and can reach purities from 95% up to 99,999%. Nitrogen pressures can go up to 12 bar(g) without the need for an additional booster. The air factors of the PPNG6-68s range are outstanding, making the return on investment very attractive compared to traditional gas supply. Boosters are also available for higher pressure. Compact installation: Pressure vessels, valves, exhaust system, sensors and controls are all integrated within a compact canopy. The PurelogicTM is the central brain of the nitrogen generator. It optimises operating costs thanks to the availability of the energy saving control; ensures maximum reliability by keeping track of the most important parameters of the generator; and offers impressive control and monitoring capabilities. The optional flow meter and inlet pressure dew point sensor can be added to the scope of supply to further exploit the monitoring capabilities of the PurelogicTM controller. ## What makes the PPNG generator unique?
