Description
DiversiTech® DRY-R™ 973KIT Moisture Eliminator (Aerosol) knocks out moisture, dissolves blockages and frees sticky TXVs/TEVs fast — without masking agents. It’s compatible with all oils and refrigerants, and one can treats systems up to 5 tons (~17.6 kW). Compressor-friendly and bloody good for speeding up tricky callouts.
Key Features & Trade Benefits
- Eliminates moisture (up to ~3 mL) — helps protect oil, driers and valves from corrosion and icing.
- Frees TXVs/TEVs — dissolves wax/acid build-up to restore metering, so your superheat settles where it should.
- Methanol-free formulation — removes moisture rather than masking it; fair dinkum performance.
- All oils & refrigerants — suitable across common HVAC/R gases (R410A, R32, R134a, etc.).
- Fast-acting aerosol + hose — quick injection with the included reusable hose for neat, no-mess dosing.
- Up to 5-ton systems per can — simple sizing keeps the job moving with fewer returns.
Why This Product Matters
Real-world: tech arrives to a Brisbane split system with erratic superheat and a sticky TXV. A measured shot of DRY-R™, 15 minutes under load, then a sniffer and gauge check — no dramas. Superheat stabilises, coil warms evenly, and the client’s back in comfort. Tools like DRY-R™ are a ripper way to restore operation fast when moisture’s the culprit. Still follow best practice: pressure test, evacuate, verify tightness — that’s how you keep the callbacks away.
Pro Tip
After using DRY-R™, verify system tightness and moisture removal with proper evacuation (deep vacuum or triple evacuation with dry nitrogen as per the Australian Refrigerant Handling Code). Then confirm with your gauges and a leak detector report. She’ll be right when you pair additives with compliant practice.

FAQs
Q: Will DRY-R™ replace evacuation?
No. It removes small amounts of moisture and can free sticky valves, but you must still leak-test and evacuate to code.
Q: Is it safe with microchannel coils?
Yes — it’s compatible with all oils and refrigerants; follow manufacturer dosing and run the system to circulate.
Q: How do I confirm the fix?
Use an electronic leak detector and refrigerant gauges to document stable pressures/temps post-treatment.
