How to Reduce Your Compressed Energy Costs?

Compressed air can be one of the most expensive forms of energy for manufacturing plants, often using more energy than other equipment. One horsepower of compressed air requires eight horsepower of electricity. With many air compressors running at efficiencies as low as 10 percent, there’s often plenty of room for improvement. Fortunately, 50% of compressed air systems at small- to medium-sized industrial facilities have opportunities for low-cost energy conservation.

The Importance of OEM Air Compressor Parts

OEM (Original Equipment Manufacturing) parts are critical to the life of your compressor. The peace of mind that you’re using genuine parts that are specifically designed and meet the specs of the manufacturer is second to none. You can also rest easily knowing that you’re using parts that meet warranty requirements and provide for extended warranty advantages. The downside is that OEM parts have the reputation of being more expensive. There is also a perception that OEM parts are hard to find with local parts dealers sometimes only carrying aftermarket brands versus the factory direct OEM parts. Given this information it’s often asked why someone would choose to use OEM parts to service their air compressor.

Here are a few facts that can help you to understand the importance of using OEM parts on your air compressor.

Cost

OEM parts can carry a higher cost; however, they are engineered to be an exact replacement for the original component. This can make sure you get the most out of your air compressor. In many cases we cannot afford for our compressors to be “down” or not functioning properly. Utilizing OEM parts can help ensure you are servicing your air compressor with the manufactures’ suggested replacement components.

Warranty

OEM parts are a requirement to receive coverage from the manufacturers warranty plan. In many cases utilizing OEM parts can offer an option for extended coverage. This can prolong the life of air compressor and give you confidence that the compressor is covered. Don’t be caught off guard when the unexpected occurs and your warranty coverage is invalid due to saving a few cents on a part or lubricant.

Quality

OEM parts work exactly as the one you are replacing. They are the same components the air compressor were manufactured with and gives you a taste of familiarity and performance. Other brands of aftermarket parts may not work correctly or be of far lesser quality with questionable manufacturing practices. You know what you are getting and you know what to expect. OEM parts are tested with the machines and matched to specifications of the original machine design.

Availability

OEM parts are easily found. Most parts suppliers carry multiple offerings one of them being a factory direct OEM part. If in the case the parts supplier does not carry OEM parts, then demand the them and do not let them jeopardize your equipment or your warranty coverage. In many cases it can be as easy as asking for the genuine OEM part versus an aftermarket brand. As an extra tool you can always check the manufacturer’s website for direct sourcing of the correct components.

Conclusion

OEM parts are the best choice for your air compressor. When looking at the guidelines above its easy to see the value in servicing your air compressor with OEM parts such as air filters , oil filters and lubricants. Following the manufacturers published maintenance schedule and utilizing these OEM parts can ensure you get the longest life out of your investment and an ROI that can benefit your bottom line. Always consult a professional and always insist that genuine OEM parts are utilized for your service needs.

Should I Purchase a Refrigerated or Desiccant Compressed Air Dryer?

Choosing between a refrigerated or desiccant air dryer is dependent on the acceptable moisture content or pressure dew point (PDP) requirement for your application.

Refrigerated air dryers are typically adequate for general purpose compressed air applications and will typically offer anywhere from a 35-40° F pressure dew point (PDP). Cost is typically much less than that of other drying technologies. Refrigerated dryers use a refrigeration compressor and heat exchanger to cool the compressed air and remove moisture. There are two types of refrigerated dryers. The first type is cycling, which is the more energy efficient option and typically used for higher flows and where the flow rate varies from shift to shift.  The Cycling or VSD refrigerated dryer, cycles on and off to deliver the correct PDP at the varying flow rate.  The other and less expensive option is a non-cycling type. Non-cycling dryers are on all the time and run at the same load as long as they are switched on.  The difference between the two, is like running your home refrigerator. You only open it when needed, and thus it “cycles” on and off as needed. Leave the door open all the time, and now you have a “non-cycling” refrigerator.   Both types of dryers should have a coalescing pre-filter to remove large quantities of water droplets and oil mist before going into the air dyer. This helps the air dryer to be more efficient in removing moisture from the compressed air. After the dryer, “after-filters” can clean up the remaining oil-mist, particles and hydrocarbons.  The type of final filter(s) is dependent upon your air systems’ ISO Air Quality Standard.

Desiccant compressed air dryers are typically used when your application requires very dry compressed air or when the compressed air supply will run outside in cold environments. Desiccant dryers can achieve dew points as low as -100. In some facilities, a Desiccant Air Dryer may only be needed for certain applications and processes.  As an example, an auto body shop generally will need only a refrigerate air dryer for the tools and general air uses, but will benefit from having very clean and dry air for the paint booth.  Desiccant Air Dryers twin towers and passes the compressed air through a tower that is filled with desiccant. The desiccant attracts the moisture during the timed cycle and then purges, which releases the moisture to the atmosphere. While one tower is drying, the other is purging and regenerating. This type of dryer does use a portion of the dried compressed air as part of the purge cycle so you need to be sure to supply enough compressed air to supply for both your demand and the purge requirement.

The different types of desiccant dryers can include non-heated, heated purge and blower purge. More energy efficient Desiccant dryers will use heated ambient air to purge the off-line tower. Further energy savings can be achieved by using a PDP monitor connected to the dryer controller which will determine when to switch the towers to start the regeneration cycle of the spent tower. The added cost of a Blower Purge Dryer will be quickly off-set by the compressed air system energy savings in most cases.

Desiccant Air Dryers require a high-quality oil-mist removal pre-filter, and a particle filter to keep dust and very fine particles from the dryer bed from getting down-stream to the air distribution system

10 Ways To Keep Your Air Compressor Working at a High Level

Everyone is always looking for ways to effectively cut costs to become more profitable. Air compression can be an expensive commodity if not properly maintained. Leaks and worn-down parts reduce the pressure your compressor can produce. Dilapidated seals and fractured piping can fail unexpectedly, creating blowouts. Unintended downtime costs money in lost production or emergency equipment hire. And then you run the risk of physical damage and personal injury claims will pile on the costs of a faulty air compressor.

Compressed air is one of the most widely used forms of energy throughout many industries, with approximately 70% of manufacturers using a compressed air system.

Compressed air can be one of the most expensive forms of energy for manufacturing plants, often using more energy than other equipment. One horsepower of compressed air requires eight horsepower of electricity. With many air compressors running at efficiencies as low as 10 percent, there’s often plenty of room for improvement.

How To Keep Your Reciprocating Air Compressor Working at a High Level?

Here are a few guidelines on how to keep your reciprocating air compressor working optimally. No matter what brand of oil-lubricated reciprocating compressor you own, doing the following three things on a regular basis will extend its working life helping to ensure a trustworthy tool for years to come:

  1. Change lubricant quarterly
  2. Purge water from tank weekly (at least)
  3. Change air filter quarterly

Oil (Lubrication)

Your reciprocating air compressor is basically an engine, and as such it requires constant lubrication to prevent excessive friction from damaging the moving parts and ultimately seizing the piston/s.  Non detergent lubricants are typically preferred for reciprocating air compressors, but make sure you respect the viscosity the manufacturer suggests for your particular compressor.

Regularly check the oil level to make sure you have the right amount of oil in the crankcase.  While the dangers of too little oil are obvious, it’s also important not to overfill a compressor with oil.  If the oil level is too high the oil can get whipped and it will foam up, losing some of its lubricating properties.  In addition, it will gain volume, further increasing your problems.  So keep checking with your dipstick/gauge as you refill with oil and make sure your unit is perfectly level to the ground when you do this.

These are just as easy to read as the dipstick variety.  The red dot represents the “OK” mark (I don’t know why they paint it red, should’ve been green).  Ideally you want to keep the oil level within the center of the dot, but as long as the level is within the dot, you are OK.

On these it’s also easier to judge the state of the oil by looking at it with a flashlight, you can often see whether it’s getting milky (water) or darker (regular wear) without having to remove a sample from the crankcase.

 Tip #1-Oil is regularly lost through the exhaust and the breather hole on the crankcase. Oil also ages and because of this, you should replace the oil after a certain amount of duty hours. A good rule of thumb that will help you comply with most manufacturer’s requirements is to change your reciprocating compressor oil on a quarterly basis.  The actual time depends on many factors and its best if you obtain the manual for your particular compressor for a clear indication on when to replace the oil.

To remove the old oil there’s going to be a bolt at the bottom side or the bottom of the crankcase in all reciprocating air compressors.  Simply remove this bolt to allow the old oil to drain into a bucket for proper disposal.  To speed up the process, make sure you remove the oil when it’s warm and remove the filling cap so you don’t draw a vacuum.=

Removing Condensate from the Receiver Tank

As the compressor’s intake happens to be ambient air, humidity in the air is sucked in on every cycle. The water vapor from ambient humidity will condense and accumulate in the tank/s.  Because of this dynamic, it’s imperative to drain the tank/s at least once a week.

Draining the tank is easy.  Locate the drain valve at the bottom of the tank and open it until moisture and air come out of the valve.  As soon as the flow of water slows to a trickle, close the valve.

If you don’t drain the tank the condensate will rust the tank’s envelope and ultimately corrosion and rust-through will occur.  The more the condensate sits in the tank, the worse it’ll get in time.

To keep condensate from building up in the receiver tank with minimal effort, include the automatic electric timer drain with your purchase of a new compressor. An electric timer drain will open at preset intervals to keep condensate from building up in the tank and finding its way down stream to the shop equipment. Zero-loss drain valves do the same thing, but they lose less compressed air pressure and also reduce the number of short cycles needed to keep the compressed air system at the pre-set level. This saves on your electricity bill.

Tip #2- Because eliminating condensate from the tank is so important to the life of your compressed air system, put a tickler on your calendar to drain the tank at least once a week –more frequently in humid environments.  Better yet, automate this task by investing in an automatic tank drain.

Intake Air Filter

The intake air filter is there to stop the compressor from taking in particles of dust in the ambient air which might cause damage to the metal surfaces inside the air compressor.  If the location of the compressor has a lot of dust and dirt in the air, this filter may need to be kept clean or changed more often than the manufacturer’s recommendations.  Use the manufacturer’s replacement intake air filter for proper fit and filtration.

Tip #3 – Refer to your manufacturer’s recommended intake air filter replacement schedule.  Replacement of your intake filter is important to keeping your air compressor in compliance with the manufacturer’s basic and extended warranty. Even if your air compressor is out of warranty,

Pros and Cons of Individual Compressor Controls

Previously we described the 6 different types of Basic Air Compressor Controls but what kind of control would you want for your compressor. Her are few pros and cons of the controls to help you assess the needs of your compressor.

Start/Stops

Pros

  • Simple control using only a pressure switch
  • Motor and compressor operate only when needed which saves energy
  • Good for small compressors that are 25 HP or less (depending on application)

Cons

  • Frequent starting wears down motor and compressor
  • Pressure setting to stop must be higher than required system pressure to build storage and may increase energy use
  • Loses of pressure control in the range of 35 psi
  • Limited to small compressors

Load/Unload

Pros

  • Motor compressor runs continuously which reduces wear  and tear associated with too many frequent motor starts
  • Tighter range of pressure (approx 10 psi)
  • Provides adequate storage and offers energy-efficient control of rotary screw, reciprocating and some centrifugal compressors

Cons

  • If applied incorrectly short cycles cause  premature wear and tear. There is minimal or no power savings on lubricant-injected rotary screw compressors
  • There needs to be proper blow down time and the storage capacity required for lubricant-injected rotary compressors to achieve energy savings and prevent lubricant foaming
  • Requires over-pressurizing to maintain minimum system pressure

Modulating

Pros

  • The motor and compressor run continuously reducing wear
  • Tighter range of pressure control (10 PSI)
  • Steady progressive capacity control that matches demand

Cons

  • Pressure ratios increase as inlet pressure is throttled
  • Inefficient at lower loads(lubricant-injected rotary compressors limited to 40-60% capacity; centrifugal compressors limited by potential surge and may require discharge blow off)

Dual/Auto Dual

Pros

  • Combines features of modulating, load/unload. and start/stop
  • Shuts down compressors when unloaded for pre-set duration which in turn saves energy
  • Better selects operation mode for small reciprocating compressors

Cons

  • Makes the control complex
  • The Over-run timer must be set to limit premature starting and stopping

Variable Displacement

Pros

  • Energy-efficient control scheme that gets down to 50% of capacity
  • Matches displacement to demand without reducing inlet pressure or increasing ratios of compression

Cons

  • Makes the control complex
  • High initial cost
  • Only available for 50 HP+ compressors

Variable Speed

Pros

  • Energy-efficient and precise control
  • Various rotating speeds and giving more displacement and power. These are directly proportional to speed rotation

Cons

  • Makes the control complex
  • High initial cost
  • Reduced full load efficiency
  • Efficiency of rotary screw compressor ends drop at lower or higher speeds
