Tulsion MB115 Resin - 25 Litre

Who Uses This Pure Water Cleaning Equipment

• Professional window cleaners: Generating vast amounts of 0ppm demineralised water for large-scale, water-fed pole cleaning contracts.
• Car valeting specialists: Using ultra-pure water to achieve the perfect, spot-free final rinse on luxury vehicles without chamois drying.
• Solar panel technicians: Rinsing delicate photovoltaics safely without leaving a mineral film that degrades light absorption.
• Laboratory staff: Supplying pure baseline water necessary for pharmaceutical testing and rigorous scientific experiments.

Why UK Professionals Trust Thermax Limited

Thermax Limited possesses over 35 years of global heritage in manufacturing premium ion-exchange chemicals. Hard water regions across the UK place severe demands on filtration media, causing cheaper resins to fail prematurely. British professionals trust the Tulsion MB115 specifically because its virgin composition delivers consistently high absorption volumes without the sudden, unpredictable TDS spikes associated with regenerated alternatives.

Safety & Maintenance

• Slip Prevention: Loose virgin beads act exactly like microscopic ball bearings. Sweeping up spills from wet concrete or van floors immediately is mandatory to prevent severe falls.
• Moisture Control: The media must remain damp to function. Expel all excess air from the bag before taping it shut to prevent the remaining stock from drying out.
• Temperature Limits: Store your supply indoors during winter. If the moisture inside the beads freezes, the internal structure fractures, permanently ruining the batch.
• Safe Handling: Always utilise protective gloves and safety glasses when pouring to avoid mild dehydration of the skin or accidental eye irritation.

Directions for Use

1. Emptying the Housing: Remove the exhausted media and rinse the internal riser tube thoroughly. Place a piece of tape over the tube opening to prevent fresh beads from falling inside and clogging your pump.
2. Optimal Filling: Pour the Tulsion MB115 beads until the pressure vessel is 80% full. You must grant the media enough physical space to swell when saturated without choking the water flow.
3. Compacting the Bed: Tap the exterior of the tank firmly to settle the resin. This prevents incoming water from taking the path of least resistance through loose channels in the bed.
4. System Purge: Reconnect your hoses and run cold tap water through the setup for a few minutes. Check the output with your inline TDS meter to confirm it has dropped to absolute zero before cleaning.

Frequently Asked Questions

Q: Will this 25L bag fit my existing 11L pressure vessel?

A: Yes, this loose resin pours easily into any standard DI pressure vessel, allowing you to fill an 11L tank slightly more than twice from a single bag.

Q: Is this suitable as a polishing resin?

A: Yes, it works exceptionally well as a final polishing stage. It is of much higher quality than cheaper resins specifically sold only for polishing, such as MB111.

Q: How do I know when to change the exhausted resin?

A: The professional standard is to replace your resin when the outgoing water reaches 5 to 10ppm on your TDS meter. Beyond this, you risk leaving visible white spotting on the glass.

Q: Can I use this after a reverse osmosis (RO) system?

A: Absolutely. Filtering the water through an RO system first removes up to 98% of the impurities, drastically extending the lifespan of this resin bag.

Q: Why is virgin resin better than regenerated resin?

A: Virgin resin has never been chemically reconstituted, meaning it possesses its absolute maximum ion-exchange capacity. It lasts longer and provides a much more reliable 0ppm output.

Q: Can I run hot water through this resin?

A: No. You must never run hot water through DI resin. It is chemically formulated to operate with cold tap water only; hot water will instantly melt and destroy the beads.

Expert Tip: Don't throw away resin reading 5–10ppm. Set up a "Double DI" system by keeping the older resin in a pre-filter vessel to handle the heavy lifting, then run the water through a second vessel filled with fresh Tulsion MB115 to polish it to 0ppm. This extends the life of your fresh 25L bag significantly.
