It is your responsibility that you ensure your facility is not squandering energy in its compressed air production process. Just consider the benefits of an appropriately sized variable speed air compressor provide you.
Whether you are a homeowner or a contractor, an air compressor is an essential piece of equipment to have in your kit. Air compressors have many uses around the home and job sites.
With an air compressor, you’ll save yourself the unnecessary time, energy, and hassle involved with many tasks around the house or job site.
Choosing the right air compressor is not as easy as you would think. If you search around an online retailer, you’ll find dozens of models available from different manufacturers. How do you know which one is best for you? In this review, we’ll help you find the best speed air compressor.
What is avariable speed air compressor?
A variable speed drive air compressor is an air compressor that takes advantage of variable speed drive technology.
This offers many benefits, such as delivering more constant pressure, protecting against power surges, and lowering energy consumption.
Most variable speed air compressor owners experience a significant reduction in their energy cost over time.
The advantages of variable speed air compressor
- Energy Savings
The most significant advantage of a variable speed drive air compressor is energy saving. A fixed speed compressor always draws the amount of power needed to meet the maximum compressed air demand.
Variable speed driven air compressors will ramp down rpm, and therefore power consumption when the demand for compressed air is lower.
Depending on the total volume of compressed air you use and the amount of variable in your process, this can add up to thousands of dollars in energy-saving annually.
- Lower Starting Currents
Motors that are controlled by variable speed drive compressors have lower starting currents, doing away with the large spikes in demand when a fixed speed motor turns on. When a fixed speed motor energizes, the inrush current can be as high as 500% of the operating flow.
The variable speed driven air compressor inverter uses a soft start/stop during this operation, automatically controlling acceleration and deacceleration levels to reduce amperage peaks. This, in turn, reduces stress on your internal power.
- System Longevity
A variable speed driven compressor motor optimizes motor speeds and compressor performance. This feature reduces stress on mechanical and electrical components, reducing the life of your system, and minimizing downtime.
- Consistent Plant Pressure
A VSD air compressor provides more stable pressure for plant operations. A fixed speed compressor operates within reasonable full bands due to the way airflow is controlled using the inlet valves.
These bands may be as much as +/- 10-30 PSIG, meaning the system’s PSI may vary by this much during the cause of operation.
A variable speed air compressor uses electronic controls and operates with a much tighter allowance, typically operating inside a +/- 1.5 pressure band. This results in much more consistent discharge pressure for all of the applications using the compressed air in the facility.
- Energy Incentives
Many power companies provide reasons for manufactures to upgrade to energy-saving systems such as a variable speed driven air compressor.
Power companies incentivize these purchases because variable speed compressors rescue the overall load on the power grid and minimize sudden spikes in demand that can overload the grid and cause an outage
Fixed speed vs variable speed air compressor
Variable speed drive air compressor has many advantages, but that does not imply that they are the right choice for every facility.
The way you used compressed air, the amount of variability in your processes, and the characteristics of your facility will all impact the choice between a fixed speed and a variable speed drive air compressor.
When to Use a Variable Speed Air Compressor
Most compressed air users could benefit from upgrading to variable speed is driven air compressors. VSD air compressors provide substantial energy saving for facilities with a high degree of variation in their requirements CFM, e.g.:
- Companies with multiple shifts have different CFM needs.
- Companies with high seasonal variability.
- Applications where demands shift significantly over the cost of a shift.
A variable speed driven air compressor is also the best fit for applications that must operate within a tight operating pressure tolerance.
When to Use a Fixed Speed Air Compressor
A fixed speed air compressor has a lower initial cost so that it can be the right choice for companies with limited access to capital funds. Parts and maintenance are also less expensive for a fixed speed compressor.
However, it is essential to remember that energy savings for a variable speed driven compressor, combined with incentives from your power company may mostly clear the cost difference between a fixed speed and variable speed drive air compressor with time.
A fixed speed air compressor may also be more efficient in the context where variations in CFM are minimal, and the system will always be operating near its maximum rating. Fixed speed compressor isCFM specifically best for:
- Companies with very low variation in compressed air demand
- Companies with inconsistent power supply. A variable speed driven compressor is highly sensitive to incoming power inconsistencies.
- Facilities with dirty, dusty, or wet ambient conditions. The electronics in a variable speed drive compressor are more sensitive to moisture and dirt than the components of a fixed speed compressor.
UsingFixed Speed and Variable Speed Air Compressors Together
In most cases, the best option is to use both the fixed speed and variable speed-driven compressors in tandem. Using several smaller air compressors instead of a single large compressor means that you keep at least part of your facility up and running.
While one compressor is down for repairs or maintenance, the second compressor can meet about 50% of your maximum compressed air needs.
When operating both types of compressors in tandem, the variable speed-driven air compressor should always have a larger capacity than the fixed speed. Here is how it should work:
- The larger VSD operates as the primary air compressor. When the compressed air needs are minimal, the VSD will run alone using just enough power to meet compressed air demand.
- When the compressed air demand overshoots the capacity of the VSD air compressor, the fixed compressor cycles on.
- The exception to this is if the base load is high or when there are different compressors controlled by the sequencer.
Is A Variable Speed Drive (VSD) Compressor the Right Choice for your Facility?
The simple economic model of matching supply with demand optimizes productivity and helps control costs. This makes sense not only in the industrial world but also when considering how compressed air is produced and used in a manufacturing facility.
Compressed air is essential to a wide range of functions within manufacturing. But poorly designed and maintained compressed air systems account for significant energy losses and waste every year.
One of the easiest ways of ensuring that your facility is not wasting energy in its compressed air production process is to consider the benefits that can be provided by an appropriately sized variable speed drive compressor.
While most plants require continuous, round-the-clock operations seven days a week, there likely are times when soothe in production presents opportunities for energy saving.
A compressed air energy audit or assessment includes a review of the demand profile, compressed air usage patterns, available air storage capacity and piping network, and the operating environment.
All those factors play an integral role in determining if a variable speed-driven air compressor can provide the energy efficiency you desire.
The most apparent advantage of variable speed driven air compressor is notable energy efficiency. A typical compressor application set up uses a direct electrical supply to power a motor that operates the compressor.
The motor runs at a continuous speed regardless of the requirements placed on it by the compressor because the power supply remains constant. The compressor uses the energy output it needed from the motor; the rest is wasted.
Operators of compressor-based systems such as refrigeration or pneumatic power supply applications, whatever the industry, can achieve energy efficiencies and cut costs by using variable speed drives to control their compressors.
Five Ways a Variable Speed Air Compressor Will Save You Money
In this age of increased conservation awareness and greater demand for resource management, people realize they need to use only what is necessary and when they need it. That is the central concept behind the variable speed drive air compressor.
When a variable speed-driven air compressor automatically adjusts the speed of frequency of energy out to meet demands, the customer saves more money by only paying the energy their application demands. Moreover, there are other peripheral advantages, as well:
- All the power you need, only when you need it.
Why should a compressor run at full speed when it doesn’t need to? Anything more than needed total water of money. The research found that electric motor systems are responsible for more than 60% of the power consumption in the industry.
This can, however, be reduced by installing or upgrading to variable speed-driven air compressors.
Many VSD is used to control pumps or fans and saves energy by running at the proper speed to match the demand.
- Increase production through tighter process control.
Using variable speed driven air compressors improves product quality and reduces production costs. By operating the motors at the most efficient speed for the specific application, fewer mistakes will occur, resulting in higher production levels with less waste and of cause higher revenues.
- Extend equipment life.
Things tend to last longer when you use them less often. The same holds for equipment. Because of the optimal control of the variable speed driven compressor motors frequency and voltage, the VSD will offer better protection from issues like electro thermal overloads, phase protection, over-voltage, under-voltage, and many more. VDS, on the other hand, allows the motor and driven load to start smoothly.
- Less Downtime.
Maintenance can also be scheduled around off-peak use, meaning production can be optimized and more profitable. If Variable Speed Driven compressors allow you to use more power when you need it, they also conveniently let you not use them when needed.
- Better alignment with local rebates and off-peak incentives available from utility companies
Believe it or not, your utility company doesn’t want you running up high bills. It costs them a great deal of money and energy to generate power, even more so when the demands are high.
That’s why many power providers offer rebates for customers who run high-demand applications during off-peak hours.
When combining energy efficiency tax incentives and utility rebates, an expected return on investment for a variable speed air compressor installation can be realized in as little as six months.
The bottom line
As drive functionality is becoming more advanced, manufactures are taking steps to simplify the usability and commissioning process, to make the benefits of variable speed air compressors more accessible to a more significant range of industrial manufacturers.
Complicated settings and adjustments can be largely eliminated from the commission process. In most cases, the commissioning can be safely and successfully performed by manufacturers or mechanics without the requirement for specialized electrical knowledge.
Setting up the application to control the speed air compressor is also easier to archive the before.
User-friendly software tools and advanced databases containing pre-loaded information on a wide range of motors, compressors, and other system components have made setting up a previously complex application much more straightforward.
What’s more, just taking into account the easy-to-measure energy-saving aspects, a variable speed air compressor will typically pay for itself within a few months, removing the investment risk.
So, improvements and simplifications to the usability of variable frequency drives, paired with the benefits when used to power compressors, as well as the cost-saving possibilities, make speed air compressors a credible and visible addition to any compressor application.
