Description
Ultipor® HT filters have a pleated, high area construction for long service life. The unique medium structure consists of a high temperature binder resin which coats the fine glass fibers. The filter’s materials of construction are qualified for uses up to 425°F (218°C) with compatible fluids. The double open ended filters are installed over a tie rod/seal nut assembly. The flow pattern is outside to inside.
Benefits
- Optimized pleat pack filtration helps to develop filter cake
- Batch to batch consistency
- Core collapse pressure rated to 75 psid (5.17 bard) @ 425°F (218°C)
- Available with retention ratings of 1, 10, 20, and 70 micron (μm)1
- Able to process tough oil fractions, containing fine suspended solids
- Large surface area provides long service life

Applications
Ultipor HT filters are designed for a variety of applications. These high temperature filters are frequently used to process tough oil fractions, containing fine suspended solids typically found in processes related to desulphurization and fuels upgrading. These fluids, left untreated, can reduce reactor runtime and foul critical process equipment. Other applications include:
- Heated tank farm fluids
- Reactor bed feed filtration (e.g. Hydrotreaters)
- Heat exchanger protection
- Gas to liquid wax products
- Lubricant processing
- Hydrogenation product polishing
- Hot motor fuel product blending
