The Second Stage of Coalescer Systems: Precise and 100 per cent Water-Blocking Technology
Dantechs Systems and Filter Solutions offers Liquid-Liquid Separator Filter Cartridges, which constitute the final and most critical stage of liquid-liquid separation processes. These elements are positioned immediately downstream of the coalescer cartridges in the first stage, forming a complete two-stage phase separation package. By retaining 100 per cent of the water droplets enlarged by the coalescer cartridge, thanks to their physical and chemical barrier properties, they completely prevent water from leaking into the clean fluid side.
Principle of Operation: Hydrophobic Barrier Effect
Separator cartridges feature a special hydrophobic (water-repellent) surface technology, which is inherently water-repellent. Whilst kerosene, diesel, jet fuel or solvents pass easily and without friction through the pores of the filter media; large water droplets emerging from the coalescing cartridge are blocked the moment they strike the hydrophobic surface. Water droplets that cannot pass through the surface accumulate on the outer wall of the cartridge; under the influence of gravity, they become heavier and sink into the water collection sump beneath the housing, whilst the clean product is discharged from the line completely free of water.
General Technical Specifications and Options
The technical parameters and configuration options for our separator cartridges, which comply with international industrial standards, are categorised below:
1. Structural Materials and Media Types
We offer two different long-life surface structures depending on process conditions, the aggressiveness of the fluid and budget optimisation:
- Teflon® (PTFE)-Coated Stainless Steel Wire Mesh: This is the most reliable and longest-lasting separator media in the industry. Its fully washable and reusable design reduces your consumables costs. It is 100 per cent resistant to acids, alkalis and aggressive hydrocarbons.
- Silicone-Impregnated Cellulose / Synthetic Media: It is widely preferred as a disposable and economical alternative, particularly in fuel lines for jet fuel (Jet A-1) and diesel.
2. Dimensions and Connection Types
To maintain system flexibility, all our separator elements fit directly onto standard industrial housings:
- Outer Diameter (OD): Typically 3.5" (~89 mm), 4.0‘ (~102 mm) and, for high-flow housings, 6.0’ (152 mm High Flow) diameter options are available.
- Lengths (Length): Supplied in specific industrial lengths such as 11‘, 14’, 22‘, 29’, 33‘, 40’, 44‘ and 56’ inches, designed to operate in perfect alignment with coalescer cartridge lengths.
- Connection Types: Double-open-end (DOE), threaded/geared base caps and industrial-grade slip-on fittings with O-ring seals to ensure leak-tightness.
