Chicago Pneumatic 20hp Variable Speed Drive Rotary Screw Air Compressor Mounted on 132 Gallon Receiver, 28-101 CFM - CPVSd 21 TM

The Chicago Pneumatic CPVSd 21 TM variable speed direct drive compressor (CPVSd) allows you to save operating costs when your application does not require the compressor's full capacity. The ES4000 microprocessor controller automatically maintains your desired system pressure and provides only the air that your system requires on a smooth consistent basis. Variable speed technology coupled with a direct drive transmission results in energy savings of up to 30%. The CPVSd 20hp compressor can function as a stand-alone machine or networked to a base-load compressor where it can function as a trim machine.

This CPVSd 21 TM is a 20hp varible speed drive compressor. It is rated to displace up to 101 cfm and will regulate its output between 28-101 cfm depending on your plants requirement and pressure setpoint. You can easily adjust the pressure via the microprocessor controller.

The CPVSd 21 series is managed by the ES4000 Advanced, an electronic control unit programmed for energy saving operation with intelligent shutdown. The ES4000 Advanced control can be programmed to shutdown in accordance with your plant air demand and reduce long periods of unloaded operation, reducing power cost. The ES4000 Advanced control feature can save a customer thousands of dollars per year.

Compressed air drives your processes and with it, the operational efficiency and performance of your company. With this principle in mind, Chicago Pneumatic has designed the CPVSd, a range of variable speed, oil-injected screw compressors with IP55 TEFC motor technology to offer your business a compressed air solution that adds value and saves you money at the same time.

The internal factory part number for this compressor is 4152032708. This model comes mounted on a 132 gallon ASME horizontal air receiver tank with a safety valve and tank drain. This model runs at a very low noise level of only 68 dBA.

Savings Through Energy Features:
Energy cost represent about 70% of the total operating cost of your compressor over a five (5) year period. That is why reducing the operating cost of a compressed air solution should be a major focus. The CPVSd 21 Variable frequency driven compressors can “cut” your energy bill by up to 30%.
