Wire Mesh Demister (also is known as mist eliminator, demister pads) is a highly efficient gas-liquid separation device.
Features:
1. High collection efficiency of up to 99% of fluid at velocity of 1 to 8m/sec
2. Provides free area of up to 98% for operation and low pressure drop (0.1" ~ 1.0" W/G)
3. A variety of materials in accordance with temperature and corrosion resistance
4. Easy to install by using manhole. Usable without any restriction and replaceable with existing facilities
5. Designed for self - cleaning (semi - permanent and economical)

Applications |
| DSM-80 |
Provides low pressure drop at high velocity and general collection efficiency. Used for collecting lager particles. |
| DSM-144 |
Mainly used in the field of petrochemical plants. Provides relatively low pressure drop and collection efficiency
of up to 90~99% |
| DSM-193 |
Most commonly used. Provides collection efficiency of up to 98~99% on 5~10 microns at velocity of 1~5m/sec. |
| DSM-390 |
Provides high pressure drop at low velocity of 1m/sec and collecion efficiency of up to 90% or greater. |
| DSM-220 |
Used for collecting minute particles sized for 1 micron, Thicker is better in case of minute particles with low density (approximately 10g/m3) |
| DSM-432 |
Used for collecting sub-micron particles 0.05~1 micronc More effective than DS-220 Style |

| DEMISTER in tower must be fixed and supported at level and Support Grid is commonly used for fixing bottom side or the upper and lower sides, which was made by welding FB 25x3t. RB6 (the same material with DEMISTER PAD) at regular intervals (APP 150mm). In addition wire of diameter 1 or 1.6 is used for fixing GRID and PAD and how to fix them as follows. |
