A separator for separating water droplets from steam is sometimes called a moisture separator or steam dryer. Thermal power stations can have water droplets impinging on and eroding turbine blades. When high-velocity steam release from nozzles (or vanes) in the steam turbine. The steam that is too wet may cause problems like water hammers and corrosion. Which can damage expensive equipment such as flowmeters and control valves. Dry steam ensures that the maximum amount of moisture is removed. The Airmax and HYDINT range of moisture separators come in a wide variety of materials and sizes. Cast or fabricated moisture separators are available. Precision engineering and manufacturing eliminate entrained moisture particles completely.
- With the thoroughly engineered design, the dryness fraction is maximized
- And the internals is designed to minimize re-entry.
Steam separators, also known as moisture separators or steam driers. These devices utilize to separate water droplets from steam. A steam dome on a steam locomotive is the simplest type of steam separator. In a stationary boiler or nuclear reactor, a “spin” is imparted to the steam so that droplets of water are thrown outward by centrifugal force and collected. Steam traps are required for all separators to collect the water droplets they remove.
The purpose of removing water droplets from steam is:
- The thermal efficiency of engines is reduced by wet steam
- Piston engines can suffer a hydraulic lock when water accumulates in the cylinders and damages them
- These particles can impinge on and corrode turbine internals, including turbine blades.
Water can build up in steam-using industrial machinery and cause steam hammer. This is a form of water hammer that happens when accumulated water ‘plugging’ a pipe is accelerated by steam until it reaches a sharp bend and breaks.
Steam drier The term may also be applied to a drier that adds heat to the steam through a low-temperature superheater.
Advantages
- By installing moisture separators before equipment like flow meters and control valves, this costly equipment can be avoided from being damaged.
- In addition to improving the overall health of the steam system, moisture separators ensure high heat transfer rates and reliability during operation.
SALIENT FEATURE-
- Multi baffle design to remove condensates efficiently and reliably.
- In general, contoured body designs ensure low pressure drops due to large flow areas.
- Compressed air lines can also be treated with this device to effectively remove moisture.
- Dimensions: 40mm to 250mm
- Operating Pressure: PN63
- Cast Carbon Steel Construction
Steam separators fall into three basic categories: baffle centrifugal, mechanical coalescence, and centrifugal baffle. In order to achieve higher efficiencies, two types of separators may be combined4
Baffle Separator
Moisture separators of this type are easy to use and have simple design elements. With the help of the separator’s one or more internal baffles, steam is redirected in one or more different directions. Due to this redirection of the streamflow, the heavier condensate droplets are removed from the steam. A drain device (steam trap station or control valve) is used to remove this heavy condensate. The baffle separator is popular in simple applications, even though it is not as effective as advanced types.
Centrifugal Separator
Centrifugal force is used to remove the entrained condensate from the steam in this type. A precise pressure and steam flow measurement are essential for centrifugal separator sizing. Centrifugal action must not be decreased in order to obtain high separation performance.
Mechanical Coalescing/Centrifugal Separator
This type of separator removes moisture in two stages. As the steam enters a stainless steel mesh, it coalesces into larger droplets. A centrifugal element removes the larger droplets in the second stage. This produces an extremely high moisture removal efficiency. The efficiency is typically 99.9%.

In certain systems, a steam separator needs to deal with moisture content. Otherwise, the following issues can occur:
- Corrosion
- Reduction in the efficiency of the system
- Failure of the components of the system
- Wiredrawing
- Malfunctioning of flow meters and control valves
- Lowering of the overall productivity of the system
Conclusion
If you are looking to eliminate moisture coming into your pneumatic tools, then it is important to have a reliable moisture separator. If you keep moisture out of your pneumatic tools, they will last longer and function better. Moisture separators are an important component of your compressed air system. Having a moisture separator can increase the longevity of your pneumatic tools. Moisture separators are an important component of your compressed air system.
