Features such as simple icon menu interface, touch panel control and USB interface make the MYPRO Touch+ the easiest way to control MYCOM compressors. Screw compressors used in the petroleum, petrochemical, refrigeration and fuel gas tend to feature lubrication, shaft-sealing and oil-control systems designed to the general requirements of API-614. Variable Speed Drive (VSD): This type of control … Instantly adapts to the compressor control requirements of all major manufacturers. GEA’s screw compressor packages These systems … They, in turn, are currently being replaced by product-adapted systems based on microcomputers. The new generation MYCOM control panel, the MYPRO Touch+, is designed as an intuitive interface to MYCOM’s industry leading compressors. This exceeds any international standard of oil injected rotary screw air compressor and is particularly suitable for customers with clean air for applications. In other words: that the inlet valve is getting it’s control air signal to open or close. No. ManagAIR® will select the best combination of compressors to run at any time to ensure the smallest possible compressor is running trim. Now let’s use the same scenario, but replace the 100 hp modulating compressor with a 100 hp Load/ No Load compressor. Screw compressors used in the petroleum, petrochemical, refrigeration and fuel gas tend to feature lubrication, shaft-sealing and oil-control systems designed to the general requirements of API-614. This invention is an improvement over the pneumatic and hydraulic control system which is disclosed in Application Ser. Compressed air installations, with your significant power needs, are an … The control air-channel system of screw air compressor. No. Intelligent Compressor Control System - The Smart and Safe Way to Run Your Underdeck System Over 7 Years of Proven In-field History! Relay systems have been replaced by programmable equipment (PLC). Screw Air Compressors Life source of industries www.elgi.com 90 - 160 kW / 125 ... distributed control system - control of compressor from control panel of customer • SCADA : compressor control through PC with remote monitoring by supervisory control and data acquisition process. Bigger is not always better!!! These systems require oil level measurement for process control… The control system will dictate three possible conditions to match the air demand: Adjustable Rotor Length: This type of control system is utilized with a constant speed motor. This is the least-efficient mode of operation for part-loaded compressors. Prior Art . With its innovative vertical design, the GA-MED VSD+ brings a game-changing revolution in … This causes the compressor to draw in less air, matching compressor capacity with air usage for relatively steady pressure control. Oct 18, 2006. Modulating control is unique to lubricated screw compressors and is the least efficient way to operate these units. The part load percent would remain the same (25%), but the hp required to make the 100 cfm would only be 44 hp. branches, AERZEN process gas screw compressors are applied in control air systems, industrial refrigeration plants, evaporation plants, mining industry and in iron and steel works. With the combination of mechanical, electrical, and control technology, the main shaft is held, rotated and controlled by electromagnetic field. From the Frick Quantum HD screw compressor control pane, Frick Unity System Controller to custom control systems, you and … ALS Air-Cooled Chiller with Screw Compressors Control Panel Features Ø Flexible control of leaving chilled water with convenient reset capability. Various strategies are used for unloading a compressor, but in most cases, an unloaded rotary screw compressor … In systems with three compressors or fewer, adequate control can … Two previous articles discussed saving energy with rotary screw air compressors: “Variable speed drives cut compressor energy costs” (PE, October 1998, p 52, File 4020) and “Conserving energy in compressed air systems” (PE, December 1997, p 103, File 4020). In systems with multiple compressors, which utilize poor efficiency control methods, there are ways to minimize the efficiency loss without purchasing new compressors. It will not only increase the performance of the compressed air network, but optimize energy by matching the air supply to your needs. DV Systems produces rotary screw compressors and reciprocating compressors built to outperform the competition. INFORMATION REQUEST FORM This article discusses the problem when it isn’t matched, which is called “control gap” and what to do to avoid it. The gas is recycled around the compressor through a large unloading valve with a pressure drop of approximately 7 psi (0.5 bar). • Password Restricted Access – Assigns up to eight authority levels and logs user access, 1 – Microprocessor panel in a water-resistant rated enclosure, with a color touch screen display and door mounted E-Stop switch, 1 – Standard Screw Compressor Control Software, 4 – Pressure Sensors (Discharge, Suction, Oil, Oil Differential) *, 4 – Temperature Sensors (Discharge, Suction, Oil, Oil Separator), 1 – Current Transmitter (Motor Amperage signal processing – Motor Current Transformer supplied by others), *Slide valve potentiometer with 4-20 ma or 1-10 volt dc signal, plus mounting bracket for panel and sensor fittings are supplied by others, Straightforward user setup in the field, easily adapts to most compressor designs, Pro-Stat® real-time graphics, color plotting, simple shortcuts.
