How to Remove Moisture from Compressed Air

Whether you can feel it or not, there’s moisture in the air and those tiny droplets of condensation are bound to make their way into your compressed air system. But, as we all know, the air must be dry in order for the system to work properly. Because air compressors are used for a wide range of applications, there isn’t one perfect solution when it comes to removing the moisture. We’ll explain a variety of applications so you can begin to understand which solution is the best for removing water from your compressed air system.

All pressurized air systems need some type of device to remove the moisture that naturally occurs. Some solutions are as simple as utilizing a drain valve, while others are more complex and involving multi-stage air drying systems. To determine the best way to remove the moisture, you have to consider what type of air compressor you’re using, and what the application is.
There are some compressed air applications that can handle a relatively low moisture content so they don’t need an elaborate air-drying setup. Regardless, moisture or liquid in the compressor tank and lines is not ideal, so drying the air and releasing the water in one form or another is a necessity.

First Step: Drain the Air Compressor Tank

There’s a drain at bottom of your air compressor tank that releases the water and oil mixture that collects at the bottom. Ideally, you’ll want to drain this every time you use your air compressor to prevent rust from building up inside the tank and to keep moisture out of your lines and tools.
If you’ve been avoiding draining your tank because it’s difficult to reach the drain valve, you can install a drain extension kit which makes it easily accessible. You can also install an automatic tank drain that will drain the tank for you after a certain period of time. Either way, this is a step that should not be skipped.

Water Trap and Filter Regulator
Typically not used on its own, a water trap is part of a multi-step system to remove as much moisture from the air as possible, especially for applications that require extremely dry air, such as painting, sandblasting or powder coating. A water trap and filter regulator system is designed to work with incoming cool air that enters one side, then circulates around the bowl where the water collects at the bottom of the trap and drains out. The air will exit through a filter, which traps other impurities in the air. Learn more about the filtration options we offer.

Consider using dryers to remove moisture from compressed air

While filters and separators are able to remove liquid moisture droplets from a compressed air system, they cannot remove water vapor. In order to remove water vapor, you must use a dryer. Cooler air holds less water, so it uses more than one system to cool the compressed air, allowing the water to drop out of the air where it can be collected and drained.

Refrigerated Air Dryer

A refrigerated air dryer works like an air conditioning unit. It is connected to the air compressor and cools the air to a specific temperature, usually between 35˚F and 50˚F. The result is a pressure dew point (PDP) of 33˚F to 39˚F. The water drops out of the air and is separated, then the air is heated up and sent through the lines for its end-use. Some applications require a lower PDP, which would require a desiccant air dryer because the condensate will freeze at 32˚F and cannot be removed.

Because this method can be costly, it’s not always the first choice for customers, however, it is one of the most efficient ways to remove moisture from compressed air and it contains a complete drying system in one unit.

Desiccant Air Dryer

In industrial operations, water vapor in compressed air equipment can lead to premature failure, corrosion, frozen air lines, quality control issues, and a range of other operational problems. A desiccant air dryer system purifies compressed air by absorbing moisture and provides air purification from -40°F PDP down to -100°F PDP.

Here are the desiccant dryers we offer.
Piping System Air Drying
You can plumb your air lines to remove moisture from compressed air. By using longer lengths of metal piping built into two or more up-and-down patterns, the air is cooled as the piping absorbs the heat. Reacting to gravity, the water drops to the bottom of the piping system into a drip leg and gets trapped, either by a water trap or a T-fitting and ball valve.
The air continues along the up-and-down piping, releasing more moisture through each segment so each drip leg will have less water. By the time the air moves through the last segment, there should be no water left in the drip leg. This can be used as a solo method of drying compressed air and it’s the most common and cheapest way to dry compressed air, either for business or personal use.

What to Consider When Buying a Compressed Air Dryer

Take these factors into consideration when trying to determine the best type of air dryer for your compressed air application:

• What is your dew point requirement?
• What utilities do you have available?
• What is your ambient air temperature?
• What is your operating pressure?
• What is your inlet air temperature?
• What is your airflow?

The dew point requirement is the first thing to consider. You may be able to eliminate some air dryers simply by looking at how much water needs to be removed for your air compressor. You may need to consult a professional to determine the PDP for your applications. The ranges below indicate what type of dryer is best to achieve specific dew points:

• 0˚- 80˚ F : Deliquescent air dryer
• 0˚-32˚ F : Refrigerated air dryer
• -40˚-0˚ F : Desiccant air dryer with a silica desiccant
• -100˚- 0˚ F : Desiccant air dryer with activated alumina desiccant

You’ll also need to consider the capacity (CFM rating) and pressure (PSIG) of your air compressor. You must choose the right size for your compressed air drying system and the application.
Of course, the purchase price is something to consider as well, but the energy use, maintenance costs, and additional cost of the pressure drop that will occur as your compressed air travels through another system should be taken into consideration. You will need to run your compressor at a slightly higher pressure with an air dryer to compensate for the loss of pressure through piping, or run it with a dryer unit to achieve the same pressure for end-use.

If you try draining your tank and utilizing a dryer system and you’re still having issues, our maintenance team can review your system and get you up and running properly. If you have questions on which system is the best to remove moisture from your compressed air system, contact us.

Top 5 Tips to Keep Your Air Compressor Running Smoothly

With growing pressure to reduce capital expenditures due to the current economic downturn, and to implement sustainable manufacturing processes, it is imperative that we optimize our compressed air use.
Here are 5 essential tips to improve the efficiency of your compressed air system:

1) Start with a Clean Slate – Clean Your Compressor
If you want an efficient compressor, you need to have a clean filtration system.
Through a given cycle, air and oil should be sufficiently filtered out. This results in the production of cool air in constant volumes and ensures a seamless performance of the machine.
If the filters are dirty, the pressure can drop. This will make the air compressor consume more energy and exert harder just to perform the basic functions. Ultimately, this would result in the untimely wear-and-tear of the compressor.
In case, the dirt stays on for several seasons the air quality could decline.

2) Inspect for Leaks
After you’ve cleaned your air compressors, ensure that there are no air leaks.
Air leaks waste close to 20-30% of the energy generated by compressed air systems. Due to this, the performance of the tools weakens, and the efficiency of the operations reduces. This results in higher operating and maintenance costs.
The problems associated with air leaks can be identified easily and do have solutions. Regular inspection can help prevent these issues.

3) Prevent Over-Pressurization
Adhering to the tips mentioned above is important. Apart from the tips mentioned above, the air compressor load needs to be optimized as well. For this, use the lowest operating pressure suited for your requirements. According to the industrial standards, if you drop the system pressure by 2 PSI, the operating costs reduce by 1%.
Installing pressure regulators to your compressed air system is also recommended. This will decrease the machine wear-and-tear and save up to 15% of the energy generated!

4) Reduce Pressure Drops
Sometimes, when compressed air travels from the compressor discharge to the actual point of use, the pressure drops. Consequently, the operators increase the generator pressure or turn up the regulators. This can increase the energy consumption.
There are two causes for this – a complicated pipework system and an inept filtration process. To counter this, the pipework should be simplified, and filters should be changed regularly. The energy will be conserved, and pressure drops reduced.

5) Conserve Heat Energy
Over 50% of compressed air systems can ensure low-cost energy conservation if used efficiently. One way to achieve efficient use of energy is to conserve heat. The heat released during the process of air compression can be reused in warehouses to warm water or produce steam for industrial processes.

What is the function of an air dryer?

The main function of an Air Dryer is to remove moisture from the air by cooling it with refrigerant. And then the water is condensed, and the air can be compressed. The result is dry compressed air, which can be used in compressed air equipment without causing any damage.

What is the working principle of air compressor?

In an air compressor, air is compressed by pulling in atmospheric air, reducing its volume and increasing its pressure. There are two types of air compressors.

1. reciprocating type,
2. rotary type

• An air compressor is a versatile device used for supplying compressed at required pressure.

Eg. - for starting main engine of the ship, compressed air is required at 30 bar

-workshop purposes for removing dust

-spray paint

Air Compressor: Two Types

1. Reciprocating (Piston) Air Compressor:-
A reciprocating air compressor makes use of piston(s) to compress air and store it in a storage tank(or reservoir) .

• Based on the number of compression stages, reciprocating compressor can be a single-stage or double-stage configuration.
• In the single-stage unit, only one piston is used to compress air, whereas there are two pistons for air compression in the double-stage air compressor.
• Double - stage compressor are used to compress air at higher pressure. As in double stage the air which is compressed in primary stage is input for the secondary stage.
• For marine purpose multistage compressor is used along with inter-coolers at every stage of compression and aftercooler (for maintaining the final temperature)

since, it compresses air at much higher pressure so it is required to fit safety devices like

• Bursting discs are fitted on the cooler shells (At water side).
• Relief valves are fitted to discharge side for every stages.
• Moisture drain valve (unloader) are fitted at each cooler side
• Cooling water failure alarm.
• Low L. O pressure alarm.
• Delivery air high-temperature alarm on aftercooler outlet (Max 93°C)

2.Rotary Screw Air Compressor

• These are either vane or screw type.
• Each stage pressure rise is limited to 7 bar only.
• It requires a high-speed drive.

(a) screw type

• Over here, two spinning helical screws or rotors are involved for compressing air (instead of using pistons), hence the name.
• As the screws mesh towards each other, air is compressed and pushed inside a storage tank.

(b) vane type
A centrifugal air compressor is also called a dynamic compressor.

• It is applicable when the demand for compressed air is high.
• In this unit, a high-speed rotating impeller increases velocity of air, which is directed towards a diffuser that converts the velocity of air into pressure.
• A centrifugal air compressor requires more energy to operate than the other two air compressors.

Air Compressor: Working Mechanism Annair.com

• In an air compressor, there are two major parts - a compressing system and a power source.
• The compressing mechanism can be a piston, rotating impeller, or vane depending upon which type of compressor you are referring to.
• As for the power, it is supplied by an electric motor or other energy sources.
• The compressing mechanism, as the name suggests, helps in compressing atmospheric air by using energy from the power source.
• The basic working principle of an air compressor is to compress atmospheric air, which is then used as per the requirements. In the process, atmospheric air is drawn in through an intake valve; more and more air is pulled inside a limited space mechanically by means of piston, impeller, or vane. Since the amount of pulled atmospheric air is increased in the receiver or storage tank, volume is reduced and pressure is raised automatically. In simpler terms, free or atmospheric air is compressed after reducing its volume and at the same time, increasing its pressure.

All you need to know about industrial Water chillers

industrial Water chillers

An industrial chiller is a portable cooling system often used in commercial and industrial facilities. An industrial chiller mainly works as a refrigeration system that either cools down a fluid or dehumidifies air. Industrial water chillers have the ability to cool pieces of equipment in a quick and efficient way. Keeping equipment cool can continue production rates at an optimal level.

Though industrial chillers are used to cool equipment, they aren’t really chilling anything. An industrial chiller doesn’t make an object colder; rather it is just removing all the heat.
Industrial air chillers and water chillers remove heat from either water or air and circulate it through a heat ex-changers to cool the surrounding air or equipment.

If you’re cooking in a kitchen and want to cool the food you’ve made, you would put it in a refrigerator. Similarly, the same idea is applied across the process of industrial chilling. An industrial chiller is used in four steps:

• Refrigeration: To chill equipment, it must first undergo a refrigeration process. This process transfers the heat that comes with the equipment, ultimately lowering the temperature.
• Evaporation: Once the refrigeration process begins, the heat will evaporate from either water or air. This process will change the water or air into vapor.
• Compression: Once the vapor is formed, it reaches a compressor that increases its temperature and pressure.
• Condensation:From the compressor, the vapor then reaches a condenser that lowers the temperature once again and turns said vapor back into a liquid.

Industrial chillers are used across a gamut of industries such as pharmaceutical, beverage, chemical, printing, rubber, blow molding, injection molding and die casting.

Advantages of water cooled chillers:

• A more precise heat transfer, compared to air-cooled chillers
• More energy efficient
• Longer lifespan compared to air-cooled chillers

Disadvantages of water cooled chillers:

• Higher up-front costs
• Higher maintenance and upkeep costs
• Requires more space than air-cooled chillers

Advantages of air cooled chillers

• Lower up-front costs
• Require less space than water-cooled chillers
• No water treatment costs, lower maintenance and upkeep costs

Disadvantages of air cooled chillers

• Shorter lifespan compared to water-cooled chillers
• Not as energy efficient
• A less precise heat transfer

Installing an industrial chiller is a must in every industry. It should be looked at as a sophisticated refrigeration system that can consistently maintain an effective productivity level.

Here are some tips & tricks for the maintenance of air compressor

Annair Drychill Tech India Pvt Ltd.

Here are the some tips and tricks  for the maintenance of air compressor from Annair drychill Tech India Pvt Ltd.

Air Compressor Maintenance tips & tricks

1.      Follow instructions: Reading your air dryer manual is a small time investment with big payoff. Manuals make you aware about maintenance schedule & operational guideline of the air dryer. Handling with the proper maintenance information will extend the life of air dryer. 

2.      Daily oil levels check: Using an air compressor with insufficient oil can be caused serious damage in your equipment that’s why before use check oil in an air compressors that use oil.

3.      Polish intake vents: Always keep air intake clean, especially when environment is dusty and dirty otherwise it may degrade the quality of your tool or else you may lose power on your compression.

4.      Replace the separator element: Depending upon model at every 1 to 4 moth this separator element needs to be replaced which helps to prevent lavish oil usage. According to few survey and analysis it is shown that compressor energy costs rise by 1% for each 2 PSI of separator pressure drop.

5.      Keep Fasteners Tight: Loosing of screws, nuts and bolts can be caused due to vibration of compressor operation. So, you have to check them and tighten all parts periodically that have loose.

6.      Clean the Fuel Tank: Same like other engines you need to clean air compressor fuel tank periodically for optimal operating conditions. You need to check you air compressor fuel tank at-least once in year for long lasting life of your engine.

7.      Clean the Heat Exchangers: A dirty heat exchanger reduce the operating temperature and life span of your air dryer that’s why you need to clean your heat exchanger regularly for better operating temperature and long life.

8.      Monitor temperature: It is also an inbuilt or safety feature which specifies acceptable operating ranges for air dryer. If system gets too hot it will automatically shut down and prevent air dryer from damage you just have to make sure it’s functioning or not.

9.      Check Hoses: Check entire air compressor’s hoses regularly because cracks in any hoses can lead to leaks and cause unwanted damage. So, change or replace any hoses which are cracked or damaged.

10.  Look and listen: Prevent your machine from damage monitoring it closely. Don’t avoid any vibration and strange noise from air dryer.
