ZM “Zero Mist” for Critical Applications
ZM coalescing filters are specifically designed for critical applications where high efficiency of aerosol removal is required. Typical applications are: compressed gas systems such as natural gas, ammonia, and glycols. Located downstream of liquid/gas contacting devices and upstream of gas turbines, compressors and chemical reactors, ZM Coalescers collect liquid aerosols and coalesce them into larger droplets which drain by gravity into the sump of the filter housing. The superior removal efficiencies of the ZM Coalescer extend the useful life of downstream equipment, thereby reducing operating downtime and labor costs. The high area, pleated design provides single stage coalescing without the need for a separate prefiltration stage to prolong coalescer life. Finally, lower saturated pressure drop combined with single stage coalescence provides lower annual operating costs. Pall coalescing filter cartridges operate economically with high separation efficiency and long life.응용분야
- Remove aerosols such as hydrocarbon liquids and water which would harm the desired process gas
- Prevent violation of strict air pollution regulations during venting
- Prevent damage to equipment such as gas flow meters and compressors
- Prevent fouling of catalysts
규격사양
Positive Seal
- Standard seal material is Buna-N. Viton (H) and Ethylene Propylene (J) are also available for optimum fluid compatibility.
Outer Drainage Layer
- Drainage of coalesced liquid and protection from re-entrainment is provided by a polymeric outer drainage layer. This guarantees consistent, high-efficiency performance.
Metal Support Core
- Axial strength and protection against liquid slugs are provided by a perforated inner support core constructed of 304 stainless steel.
Outer Cage
- Media support during operation is provided by a 304 stainless steel outer support cage.
Primary Coalescer (Pleated Filter)
- The primary coalescer is a high area, pleated, epoxy coated fiberglass medium which is specially treated. It is surrounded by non-woven polymeric support and drainage layers. This provides unsurpassed separation efficiency over a wide range of flow conditions with minimum pressure drop.
304 Stainless Steel End Caps
- Cartridge strength and prevention of contaminant bypass is provided by the 304 stainless steel end caps.
