Many industries consider it a standard practice to use a variable speed drive (VSD) air compressor because of its high-level efficiency and convenience. Variable-speed technology has proven to be more practical and energy-saving than the fixed-speed variant. Take advantage of its benefits; find a VSD compressor at C&B Equipment.
We offer a selection of Gardner Denver VSD air compressors that are ideal for a wide range of applications. We carry the LRS Series (single-stage), S Series (single-stage), and VST Series (two-stage). Browse below for details on each available model.
We’ve briefly touched on the differences between a variable-speed air compressor and a fixed-speed air compressor above. Let’s explore this topic further.
Also called “frequency-controlled compressors,” variable speed compressors have an automatic system that adjusts the motor speed according to the air demand. In other words, it only runs at the required speed, which is ideal in facilities where compressed air system use is sporadic and unscheduled.
This also means VSD is energy-efficient. It can use up to 50% less energy than the standard, fixed-speed compressor. VSD air compressors also produce less noise, allowing for a more pleasant indoor environment.
These compressors run at 100% capacity at all times. They use a consistent amount of energy and run at one speed (RPM). This is why fixed-speed compressors are also called “idling compressors.”
If anyone in the facility needs air, an inlet valve will open to release it. The compressor doesn’t rev its motor up and down during this process, it just releases air through a simple, open-flap mechanism.
A motor that runs consistently might sound reliable, but it comes at a price. Fixed-speed air compressors offer little room for energy efficiency, so users can’t expect reductions in the costs of their energy consumption.
On the plus side, fixed-speed air compressors cost less than VSDs. They’re also the better option for applications that need consistent air temperature.
Gardner Denver single-stage variable speed (VS series, 11 kW to 170 kW) & (LRS 7kW to 290kW) compressors are ‘ground-up designs and produce the widest turndown range in the industry. High efficiency and reliability on variable load or trim applications will be found in all Sedalia, MO-made machines.
Gardner Denver two-stage variable speed (VST series, 55 kW to 260 kW) compressors deliver maximum efficiency to the plant across all loads. These two-stage models employ 8-12% more efficiently than single-stage models. The VST compressor comes packaged with two motors and two air-ends for optimum performance.
