IN FOCUS Pumps, Compressors, Drives Oil-free two-stage screw compressors Modular medium voltage drive With the addition of ten new models, Compair‘s D-Series of oilfree two-stage screw compressors covers a flow range from 8.9 to 51.8 m 3 /min. The new compressor versions (from 160 to 315 kW), which also utilise a Compair designed two-stage airend, offer oil-free and siliconefree air, in accordance with ISO 8573-1 Class 0. The D-Series delivers improved efficiencies and produces 12 % more air compared to the previous range. Electric IE3 and IE4 motors and other components all meet and exceed stringent European standards and those from other jurisdictions, providing high quality and premium efficiency. All connections are on the same side of the compressors, allowing for simple installation with no specific foundation requirements. Designed and built for continuous use in applications with up to 45 °C ambient temperatures, the D-Series features a water regulation system around the airend and hardened rotor coating to ensure long life. Low power consumption is also delivered, whilst maintaining high air outputs. » www.cpp-net.com Online search: cpp0117compair Danfoss designed the medium voltage Vacon 3000 drive for voltages between 3300 to 4160 V. The concept is based on modular components enabling complete customisa - tion of the enclosure design complemented by the simple, well-known communication interface from the Vacon 100. The AC drive solution for powers up to 6 MW with the prospect of increasing, is characterised by the same modularity as in other Vacon high power drives. Hereby modules can be connected in parallel, providing the user and system integrator even more flexibility. This is not a standard solution in a conventional cabinet. Due to the modular build the Vacon 3000 can be designed into many applications with limited space. The watercooled modules make it ideal for adverse ambient conditions. In addition the integrated water cooling makes it very compact for its class and the robust design of components increases reliability and durability. » www.cpp-net.com Online search: cpp0117danfoss High-efficiency drives for intralogistics Astonishingly quiet high-pressure plunger pumps Kamat has revised the mechanical powertrain of its triplex plunger pumps for pressures up to 3500 bar. The pumps operate much quieter, and the drive systems consume less energy. The job was difficult, because of the asymetrical crankshaft that moves the plunger via crossheads. The asymmetry resulted in much stronger vibrations, which made it difficult to achieve acoustic decoupling using damping elements due to the vibrations. The designers therefore developed split gear cases, where a symmetrically balanced crankshaft takes over the power transmission between the drive and the plunger. A specially designed double helical gearing also contributes to the increased running smoothness and reduced noise of the pumps. This design is now used in the triplex pumps with power classes ranging from 80 to 800 kW. It also forms the basis for the drive design of the quintuplex pumps. » www.cpp-net.com Online search: cpp0117kamat High-voltage motors up to 70 MW With its high-voltage motor series Simotics HV HP, Siemens is able to cover an extended power range of up to 70 MW. Its modular concept makes this series ideal for precisely tailored solutions in the high power range. All the models of the Simotics HV HP series are available as synchronous or induction motors, in Nord Drivesystems offers standardised drive units in three highly efficient and easy-to-service versions for typical requirements in conveying applications. Logidrive systems are designed for horizontal or inclined conveyors. They integrate the safety functions STO and SS1 according to DIN EN 61800-5-2 and DIN EN 60204-1. The motors feature a high overload capability. The system is fully modular: all components can be serviced separately. This reduces maintenance and repair costs. Nord integrates all standard fieldbus and Industrial Ethernet interfaces directly a high- or low-temperature version, with gas and dust explosion protection and with a wide variety of cooling methods. Simotics HV HP complies with a wide number of country-specific certification requirements such as API, TR CU, CSA and Nema. » www.cpp-net.com Online search: cpp0117siemens in the AC vector drive.

Screw compressor with integrated rotation dryer Kaeser offers their dry-running rotary screw compressors with integrated attachment rotation dryer. The i.HOC dryer provides a Noiseless and oil-free compressors The oil-free compressors of Dürr Technik‘s Marathon series is now available with a specially developed silencer. Thereby the noise level is reduced to 3 dB(A). A highly intensive cooling which is integrated in the crank casing ensures a continually running up to 10 bar. The big filter surface of the Marathon suction filter guarantees a long lifetime, minimal maintenance and an optimal suction behavior. Smooth running of the compressor is achieved by a special aluminum piston with a heat-resistant coating out of PTFE foil. The free air flow varies between 80 and 300 l/min depending on the model. » www.cpp-net.com Online search: cpp0117duerr stable supply of compressed air with pressure dew points to -30 °C even in challenging environmental conditions – and also saves energy. i.HOC stands for integrated heat of compression dryer. This means that the heat, which is a by-product of air compression, is used to regenerate the desiccant. The result is reliable air drying with high efficiency and low energy costs – even for varying quantities of air. With i.HOC low pressure dew points can be reliably achieved even in challenging conditions, such as low pressure, high temperature or low load operation. This is made possible by a highefficiency radial blower with variable control, which serves two main purposes: to compensate for the pressure lost in the drying process and automatically adapt the drying process to changing operating conditions. Full-flow regeneration, together with an additional patented process, ensures dependable drying, without additional electrical heat sources or coolers, even at ambient temperatures as high as 45 °C. The integrated Sigma Control 2 compressor controller manages the entire process, controlling the radial blower and drum drive of the integrated rotation dryer. » www.cpp-net.com Online search: cpp0117kaeser METERING MEASUREMENT & CONTROL TREATMENT DISINFECTION IMPLEMENTATION Promises a lot … and delivers: precise solenoid drive, predictive control technology and intuitive operation.
