Additional Information |
N/A
The right variable speed compressor in the right application delivers significant energy savings and a stable, consistent air supply. Poor system design can increase energy cost up to 5 times. ESP 20/20 qualifies the compressor for GDXTRA, Gardner Denver™'s extended warranty program on airends, delivering the tools to ensure the compressor is operating at peak performance with the peace of mind that the compressor is protected. |
Your Business is Unique, so is your Compressed Air System |
N/A Typically, air demand in a plant varies widely throughout the day. In addition, fluctuations can occur from shift-to-shift, weekday-to-weekend, and season-to-season. Pressure requirements can also change from machine-to-machine or from one application to another. You need someone to evaluate your unique, often complex requirements and recommend a tailored solution. |
The Wrong Solution is Expensive |
N/A Compressed air is not free and has a big impact on plant productivity. The wrong air system is costly - in the form of excessive energy, repair and maintenance costs, downtime, poor compressed air quality, unacceptable noise levels, and more. System design and compressor choice are important decisions with long lasting implications. |
The VS Series™ - Rethinking Everything |
N/A The VS Series™ design started from a "clean sheet of paper". This approach is critical to making a variable speed compressor that delivers optimal performance over a wide operating range. For maximum reliability, key features must be part of the design foundation. With the VS Series™, an international team of world-class engineers delivers a truly purpose-built compressor product line. |
Technology Paves the Way |
N/A
Our engineering team utilized the latest technologies in developing the VS Series™ so that it is loaded with the critical product benefits you want. Important technologies used include:

The Benefit |
N/A
Efficient, Reliable, Flexible…Unmistakable The VS Series™ is a complete, revolutionary compressor line that is a Smarter Solution to your Complex Needs. The efficiency limitations of competitive variable speed drive compressors have been eliminated to establish a new standard in this area. The flexibility of this line exceeds that of any other compressor. This means stable pressure in the plant and maximum productivity. Finally, the VS Series™ is so reliable it is backed by the best warranty in the business. |
Evaluate Efficiency Everywhere - Full Load, Part Load, No Load |
N/A
Upper Range - Part Load Efficiency Gains Importance At full load in the upper flow range, top performing base load modulating compressors are typically better performers. As air-flow decreases, the other compressor types become more energy efficient. Middle Range - VSD Takes Charge In the middle range, the VSD compressor shows significant energy savings compared to the other compressor types. At about 75% of a compressor's full load flow, the VSD compressor is 5 - 15% more efficient, and the advantage increases as flow decreases. Lower Range - VSD is Far Superior In the lower range, the VSD compressor savings become even greater. A variable speed compressor handling a second shift that uses only 40% of the air requirements of the first shift is just one of many ideal applications for a VSD compressor. |
The VS Series™ Provides Efficiency Everywhere - Full Load, Part Load, No Load |
N/A
Typical VSD compressors are not designed to maximize performance. Most manufacturers simply adapt their current products to a variable speed drive and motor. The VS Series™ products are specifically designed to obtain the greatest efficiency across the entire operating range. To maximize efficiency, the VS Series™ eliminates every possible kW. Unlimited Start/Stop Operation When air is not needed VS Series™ compressors stop running without venting air you've already paid to compress. Thus, no Power is used when no air is needed. When air demand returns, these compressors "soft" start against a pressure load. The result - energy consumption is kept to an absolute minimum. Airends Optimized for Variable Speed Operation Gardner Denver™ invested millions of dollars to develop new airends and new rotor profiles for the specific purpose of maximizing efficiency in variable speed compressors. Enduro® + airends perform efficiently at all speed More Models to Choose from Every platform of the VS Series™ has several models from which to choose. This means you can better match your needs to a specific compressor and get the best value for your application. Designed for Minimum Pressure Drop For every 2 psig of pressure drop through a compressor package an additional 1% of power is consumed. That's why every area on these compressors was designed so that air flows with the least possible restriction. The Efficiency Foundation - A Matched Motor, Drive and Airend We started with an airend and rotor profile design that offers industry leading turndown and performance. We partnered with an industry leader to develop a perfectly matched motor and variable speed drive to work with our airend for optimum efficiency and turndown capability. VS 15 - 170 kW (20 - 228 HP) models are direct drive, so there are no efficiency losses from belts. |

Reliability to Maximize Uptime |
N/A
Designed for Reliability We used a "clean sheet of paper" design approach, with all components carefully selected and tested for their specific performance and purpose. The VS Series™ design incorporates smart injection technology which communicates with the AirSmart™ controller to maintain the discharge temperature of the compressor above the dew point (based on the ambient temperature of the operating environment) to prevent condensate from forming in the lubricant. Smart! Gardner Denver™'s integrated Tempest design through the 70 kW model eliminates leak points through smart, efficient, latest technology construction. Our new Enduro® + airends for the 80 kW and larger models were developed to be more efficient and reliable than ever. A Warranty Like No Other In simple terms, VS Series™ compressors have a best in class warranty. The five-year warranty covering the drive motor, airend, variable frequency drive, controller, and more is unparalleled. With regular lubricant, sampling, and use of OEM parts and lubricant, you are guaranteed to have a compressor that exceeds your reliability expectations. |
The AirSmart™ Controller Orchestrating your Compressed Air System |
N/A
Simplicity The AirSmart™ Controller was designed to make the operator interface with the variable speed drive transparent. You don't need to be an expert on variable speed drives to operate our compressor. The controller takes care of the details. The controller automatically adjusts the compressor's performance to meet your changing air system demands - saving you energy dollars. Changing the discharge pressure is as easy as pressing a button. No longer is there a need for a new machine when your pressure demands change. Communication and Sequencing The optional communication module allows the VS Series™ units to talk to each other and other Gardner Denver™ compressors to optimize system efficiency. This isn't just an hour-balancing, on/off sequencing scheme. Our controller allows the system to truly optimize efficiency because it knows the capabilities of other machines and orchestrates their operation. The communication module also allows remote monitoring of the VS units. Expansion Capabilities Also available is an optional expansion module that allows additional I/O capabilities for additional monitoring equipment, such as a pressure transducer. The expansion I/Os are standard on VS 80 - VS 260. Advanced Display The controller has a four line display with menus and tactile buttons for easy navigation. Two lines display operating information such as pressure, temperature, operating hours, etc., while the other two lines display advisory messages, shutdown messages, recommended part numbers, and service contact information. |
Energy Efficient at All Load Levels |
N/A The single largest "cost" item, during the life of a compressor is the cost of the electricity required to run the compressor.
