A compressed air dryer is used for removing water vapor from compressed air. Compressed air dryers are commonly found in a wide range of industrial and commercial facilities. The process of air compression concentrates atmospheric contaminants, including water vapor. This raises the dew point of the compressed air relative to free atmospheric air and leads to condensation within pipes as the compressed air cools downstream of the compressor.

Excessive water in compressed air, in either the liquid or vapor phase, can cause a variety of operational problems for users of compressed air. These include freezing of outdoor air lines, corrosion in piping and equipment, malfunctioning of pneumatic process control instruments, fouling of processes and products, and more.

Description:

An Air Compressor is a device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When tank pressure reaches its upper limit the air compressor shuts off. The compressed air, then, is held in the tank until called into use.

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver airs at high pressure. The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged.

Advantages:

• Relatively cheap.
• Easy maintenance (easy to understand the inner working).
• Suitable for high pressures.

Description:

Positive Displacement blowers are similar in principle to positive displacement pumps in that they use mechanical means to squeeze fluid and thereby increase pressure and/or velocity. Centrifugal designs, on the other hand, impart velocity and pressure to media by flinging them outward with impellers. Among positive displacement blowers, the Roots, or rotary lobe, type is common, which uses two counter-rotating lobed rotors to move fluid through the blower, much the way a gear pump moves oil or other viscous liquids. A cutaway blower (below) shows one of the two rotors. Positive displacement lowers are often driven by direct-coupled electric motors but they can be driven by gas engines, hydraulic motors, etc. in unusual circumstances.

Centrifugal blowers are routinely used for combustion air supplies, on cooling and drying systems, for fluid bed aerators, with air conveyor systems, for dust control, etc. Positive displacement blowers are also used in pneumatic conveying, and for sewage aeration, filter flushing, and gas boosting, as well as for moving gases of all kinds in the petrochemical industries.

Description:

Vacuum pump is a universal design with the feature to convert it to a single stage compressor. This feature is very useful for large tank leakage test under vacuum or under pressure.Dry type vacuum pump-only useful for handling of gases.Easy to install requiring no foundation.Higher efficiency compared to other types or other makes of vacuum pumps.

Low maintenance.While using liquid tanks in chemical plants for vacuum, the provision of scrubber tank is available as an additional equipment to prevent the liquid from entering the pump.Simple design makes it easy for any shop mechanic to dismantle and assemble the pump without any mismatch of the parts.
