Vortex VSD Series compressors are exceptionally efficient variable-speed drive rotary screw compressors requiring minimal maintenance. Motors controlled by VSD have lower starting currents, eliminating the large spikes in demand seen when a fixed speed motor turns on. Smart integration eliminates leaks and pressure drops maximizing reliability. Understanding the cause of the vibration and how to resolve them will be critical in keeping your compressor in proper working order. One of the ways the DemandSmart system in Nx Series compressors maximizes energy savings is with a variable speed drive (VSD). VSD will ramp down RPM, and therefore power consumption, when demand for compressed air is lower. Intuitive controls and diagnostics make them easy to use and service, too. When correctly sized and implemented for the proper application, variable speed compressors have the potential to deliver significant energy savings. Factory filled synthetic lubricant. According to the U. S. Department of Energy, electricity represents more than 75%¹ of the total costs of an air compressor over its lifecycle. Master Slave – this controller can switch from one unit to the other and maintain the same use of hours, it can adjust the pressure to be the lead or the lag unit.
Elimination of the waste of compressed air in ON-OFF regulation determined by the need to depressurise the air-oil tank every time a vacuum is created in the machine. Importantly, a VSD compressor is not designed to operate continuously at full speed. Effectively minimizes noise levels: solid steel base frames & floors, powder-coated, heavy gauge, acoustically insulated steel cabinets & sound attenuating foam barriers. With this type of compressor, the pressure in the storage tank gets smaller as the compressed air gets depleted. An adjustable speed drive can take on 50-70% of that motor full load current by starting the motor at zero frequency and voltage, it works by magnetizing the motor winding's and builds the frequency and voltage slowly, in short the variable speed drive starts as a zero speed and accelerates smoothly up to your ogrammable controls allow for adjustable operating speeds as well. Gardner Denver LRS Series Variable Speed Compressors. Secondly, and most importantly, customers want to run more efficiently and save money on total cost of ownership and energy costs.

Power companies incentivize these purchases because VSD reduces the overall load on the power grid and minimizes sudden spikes in demand that can overload the grid and cause an outage. Find out everything you need to know about variable speed screw air compressors here including: An air compressor with Variable Speed Drive (VSD) automatically adjusts the compressor's operating speed to match production of compressed air to demand in real time. Because fixed-speed compressors are running at full speed all the time, they are going to be under much more stress than a VSD compressor. Variable speed drive air compressors have many advantages, but that doesn't mean they are the right choice for every facility. When that pressure reaches a set value, the motor runs again to drive more air into the tank. Be sure to check oil levels frequently and change oil on the schedule recommended by your operating manual to prevent problems like varnish that can damage the rotors.
The VSD will then adjust its RPM to meet the total demand. Variable-speed air compressors have lower starting currents. Best of all, its affordable. Rotary screw air compressors are available in both fixed speed and variable speed. This often saves a lot of energy and money. A belt-driven compressor has a higher risk of downtime and maintenance- related costs. Constant regulation of the working pressure with a maximum drift of 0.
