ResinTech SIR-800, Oxygen Scavenger Anion Resin, 1 Cubic Foot
ResinTech SIR-800 is a sulfite form strong base gel anion resin. SIR-800 removes oxygen from water by converting sulfite to sulfate on the resin exchange sites. ResinTech SIR-800 is intended for oxygen removal applications and for other processes where an immobile reducing agent is needed. SIR-800 is supplied in the neutral sulfite form.
Features & Benefits
- Supplied In The Sulfite Form: Resin is supplied in the sulfite form for oxygen removal and other redox reactions
- No Ionic Dumping: Unique manufacturing process places the maximum level of sulfite onto the resin and minimizes the tendency to rinse off sulfite in exchange for other ions
- Low Odor: Yields very little of the typical pungent odor characteristic of low pH oxygen scavenger resins
- Special Packaging Available To Extend Shelf Life: Gas barrier drum liners are available to prevent air from contacting the resin, greatly increasing shelf life
- Controlled Particle Size: 16 to 50 mesh size provides a low pressure drop and superior kinetics

Applications:
- Oxygen Removal: ResinTech SIR-800 is a strong base anion resin supplied in the sulfite salt form for removing oxygen from water. Sulfite on the resin reacts with oxygen (in the water) to form sulfate on the resin. Virtually complete removal of oxygen can be obtained if the flow rate and pH are carefully controlled. The rate constant for oxygen removal slows as pH is increased beyond neutral. SIR-800 is normally used in recycle applications where the feed is partially deoxygenated water. For once-through applications where complete removal of oxygen is required, a reduced flow rate and/or reduced pH is necessary.
