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.
