Why flush when you can PURGE?

Standard “flushes” are often just low-pressure solvents that rinse the bottom of the pipe. Purge is different. By combining a proprietary high-concentration solvent with a 140+ PSI delivery system, Purge doesn’t just rinse—it obliterates obstruction.

The industry is full of “convenience” cans that lose pressure in cold trucks or fail to push solvent up vertical line sets. Purge is engineered for the reality of the job site. The elevated pressure ensures consistent velocity in low-temperature environments and long commercial runs, while the active formula chemically emulsifies the sludge, carbon, and acids that cause compressor burnout, turning those line sets into a like-new state.

Manufacturer’s Tech Note: We intentionally pressurize these cans to 140+ PSI because we know technicians leave them in freezing vans overnight or have to work inside walk-in coolers. Standard 55 PSI cans lose pressure in the cold and can’t push sludge up a vertical riser. Purge maintains velocity even in tough conditions.

The Efficiency Math: Do More with Less

Because Purge relies on powerful active ingredients rather than propellant fillers, you get superior coverage per canister.

1 lb Canister: Services 3–6 Tons (vs. the industry standard of 3–4 tons).
2 lb Canister: Services 5–10 Tons (Best value for large systems).

Professional Application: Designed for the modern technician, Purge is the essential tool for R-410A retrofits, A2L system conversions, new component installation, and heavy-duty burnout maintenance.

Why Low-Pressure Flush Fails Your Line Set

THE PAIN POINT (Standard Flush)	THE PURGE ADVANTAGE
“The Pressure Drop” Standard 55-65 PSI cans lose velocity in vertical risers, leaving heavy sludge trapped at the bottom of the loop or solvent all over the floor.	“140+ PSI Velocity” Maintains high mechanical scrubbing force to blast through complex piping and lift heavy debris out of vertical runs. Solvent goes exactly where you want it..all the way through the run.
“The Cold Weather Fail” Propellants lose power in cold trucks or walk-ins. A cold can often just “trickles” out, failing to scour the pipe.	“All-Weather Reliability” Engineered with high initial pressure to ensure consistent flow even in winter conditions or walk-in freezers.
“Rinsing vs. Cleaning” Weak solvent blends flow over carbon deposits or flash off before they can dissolve them, leading to repeat burnouts.	“Chemical Emulsification” High-concentration formula chemically breaks down and suspends hardened carbon and tar so it can be ejected.

Directions for Purge High-Pressure Flush

1. Preparation & Yield Planning

Step 1: Isolate & Protect. Remove or bypass TXVs, pistons, and filter driers. Never inject into a compressor.
Step 2: Establish Flow. Place a waste container at the exit point. Flush from the inside-out.
Step 3: Secure Connections. Gently wrench-tighten all connections. Hand-tightening is insufficient for 140+ PSI.

Tech Tip: To ensure full-volume cleaning, use pliers to slightly crimp the exit of the copper discharge line. This creates back-pressure, forcing the liquid solvent to fill the pipe completely rather than just running along the bottom.

CONTAINER SIZE	YIELD	APPLICATION SCOPE
1 lb Canister (PRG-1)	3 – 6 Tons	Residential / Standard: Sufficient for most residential line sets up to 50ft.
2 lb Canister (PRG-2)	5 – 10 Tons	Commercial / High-Yield: Best for long vertical runs, large diameters, or heavy burnout contamination.
Required Chase	Nitrogen	Mandatory: Always chase with compressed dry nitrogen immediately after injection.

2. Application & Cleaning

Inject: Hold canister upright. Inject in short, controlled bursts (10-20 sec for small lines, 30-40 sec for large lines).
The Nitrogen Chase: Immediately disconnect Purge and blast Nitrogen through the line to act as a squeegee.

3. Rinse & Completion

Inspect Discharge: Look at the waste container. If fluid is dark/black, repeat the flush until it runs clear.
Evacuate: Pull a deep vacuum. Purge will flash off rapidly, leaving zero residue.
Dispose: Dispose of waste solvent in accordance with local regulations.

FAQs

Frequently Asked Questions: Purge High-Pressure Flush

Application & Performance

Q: How many tons can a single aerosol clean?
A: Purge is engineered with a high-concentration solvent that provides superior yield compared to standard 1 lb flushes.

1 lb Canister (PRG-1): Cleans 3–6 Tons.
2 lb Canister (PRG-2): Cleans 5–10 Tons.

Note: Actual coverage depends on the severity of the burnout or contamination level.

Q: Why can’t I just use high-pressure Nitrogen to blow out the line?
A: Nitrogen is a gas; it pushes loose debris but cannot clean. Purge is a solvent. It chemically dissolves hardened carbon, tar, and oil that Nitrogen flows right over. You need the chemical action to lift the contaminant, and then the Nitrogen to push it out.

Q: Do I need a specific flush gun to use Purge?
A: No. Purge utilizes a universal oscillation valve that fits most standard HVAC flush guns and injection tools available at wholesalers. You do not need a proprietary adapter.

Q: Why is the pressure so high (140+ PSI)?
A: We pressurize Purge to 140+ PSI to ensure the solvent maintains velocity through long vertical runs and complex piping. Low-pressure flushes (typically ~55 PSI) often lose momentum in these scenarios, allowing sludge to settle. The high pressure ensures a true mechanical scouring action.

Troubleshooting & Tips

Q: The solvent coming out of the line is still dark. What do I do?
A: If the discharge is dark or black, it indicates heavy carbon or oil contamination (common in severe burnouts).

Repeat the Flush: Continue flushing until the solvent runs clear.
Upgrade Size: If you are working on a heavily contaminated system, you may need the additional volume of the 2 lb (PRG-2) canister or a bulk cylinder.

Q: I only used half a can. Can I save the rest for the next job?
A: Yes. Purge aerosols do not expire once opened. To ensure the nozzle doesn’t clog, turn the can upside down and spray for 1 second to clear the valve stem. Store it in a cool place, and it will be ready for your next service call.

Q: The canister feels cold or pressure seems low.
A: While Purge performs better than competitors in the cold, extreme low temperatures will naturally lower the pressure of any aerosol.

Solution: If the can has been sitting in a freezing truck, warm it to room temperature (60°F – 70°F) before use to restore full 140+ PSI pressure. NEVER heat with a torch or open flame.

Safety & Compatibility

Q: Will Purge damage the O-rings in my reusable Flush Gun?
A: No. Purge is safe for short-term exposure to standard Viton and Neoprene O-rings found in most flush kits. However, as a best practice, always blow straight nitrogen through your flush gun after the job is done to ensure no solvent sits on the seals during storage.

Q: Can I use this to clear a clogged condensate drain line?
A: ABSOLUTELY NOT. Purge is a strong chemical solvent designed for metal piping. It can melt PVC/CPVC drain lines and destroy condensate pumps. Use a designated drain opener (like Vapco’s Solve) for drains.

Q: Is this product safe for A2L Refrigerant Conversions?
A: Yes. Purge is ideal for converting systems to A2L refrigerants (like R-32 or R-454B). Its high-solvency formula completely removes mineral oil and alkylbenzene residues that are incompatible with new A2L lubricants.

Logistics & Large Volume

Q: I have a VRF system or Chiller. Do you have larger sizes?
A: Yes. For large volume applications where aerosols are insufficient, we offer bulk cylinders:

PRG-5: 5 lb Cylinder
PRG-10: 10 lb Cylinder

These cylinders provide massive liquid volume for large-diameter pipe and commercial runs.

Q: What is the shelf life?
A: Purge aerosols have a shelf life of 5 years from the date of manufacture when stored properly in a cool, dry place out of direct sunlight. Manufacture warranty of 1 year.

Q: How do I dispose of the waste solvent?
A: The used solvent captured in your bucket will contain hazardous system contaminants (acid, oil, sludge). Do not dump it down the drain. Dispose of it in a waste oil container in accordance with your local EPA regulations.  ________________________________

DANGER: Operates at 140+ PSI. Never connect directly to a Nitrogen line via manifold (risk of burst). Use only in well-ventilated areas. Wear chemical-resistant gloves and safety glasses.

Field Guide: Contaminant Removal Matrix

Purge utilizes a high-concentration solvent blend designed to emulsify specific HVAC contaminants. The following matrix details performance against common line set obstructions.

TARGET CONTAMINANT	TYPICAL SOURCE	ACTION	PERFORMANCE / WHY IT WORKS
Compressor Burnout Residue	Carbon / Sludge / Acid	Emulsifies & Ejects	High solvency ratio breaks down hardened carbon deposits while 140+ PSI pressure mechanically scours the pipe wall to prevent redeposition.
Mineral Oil / Alkylbenzene	R-22 Retrofits	Miscible Displacement	Purge is fully miscible with mineral oils, allowing it to lift the oil from the copper surface and carry it out of the line set for a clean R-410A conversion.
Moisture / Water	System Leaks / Open Lines	Displaces	High-density solvent physically displaces standing water. Low boiling point (106°F) ensures remaining moisture boils off rapidly during vacuum evacuation.
Polyol Ester (POE) Oil	A2L / R-410A Systems	Solubilizes	Effectively cleans POE oil residue during component change-outs or compressor replacements.

System Material Compatibility

MATERIAL / COMPONENT	STATUS & PROTOCOL
Line Sets & Coils (Copper/Aluminum/Steel)	✅ SAFE (Engineered for all standard piping metals)
Elastomers (Viton/Neoprene)	✅ SAFE (Safe for short-term exposure during flush cycle)
Plastics & Painted Surfaces	⚠️ CAUTION / AVOID Solvent may soften ABS, acrylics, or strip paint. Wipe up spills immediately.
Internal Valves (TXV / Solenoid / Reversing)	❌ BYPASS / BRIDGE Solvent can damage valve seals or lodge debris in pilot tubes. Must be bypassed.
Compressors & Filter Driers	❌ DISCONNECT / REMOVE Do not flush. Isolate line sets before injection.

Directions for Purge High-Pressure HVAC Line Set Flush Aerosols:

WARNING: For use by professional HVACR technicians only. Purge operates at 140+ PSI. Failure to follow these instructions may result in injury or equipment damage.

Safety & Hazard Warnings

DANGER: Nitrogen Back-Pressure. Never connect the Purge canister directly to a Nitrogen line via a manifold. If Nitrogen back-pressure enters the aerosol can, it may burst.
Ventilation: Use only in well-ventilated areas. If flushing indoors, open windows or use fans to exhaust fumes. Try to flush from inside to out where possible.
PPE: Wear safety glasses and chemical-resistant gloves. Purge is a high-strength solvent that degreases skin instantly.

Phase 1: System Preparation

Before cracking the seal, ensure the system is isolated to prevent damage to sensitive components.

Isolate & Protect:
- Compressors: Never inject solvent directly into a compressor.
- Metering Devices: Bypass or remove TXVs, pistons, and filter driers. Solvent can lodge debris in these small orifices.
- Large Components: If the system has a receiver or accumulator, inspect it visually. If heavily contaminated, bypass and clean separately or replace.
Establish Flow Path:
- Disconnect the line set from the indoor and outdoor units.
- Whenever possible, plan to flush from the inside – out to the exterior. This moves fumes and contaminants outside.
- Place a bucket or waste container at the exit point to capture the solvent and sludge.
High-Pressure Connections (Critical Step):
- Because Purge operates at 140+ PSI (significantly higher than standard flushes), hand-tightening may not be sufficient.
- Gently wrench-tighten the connection between the injection valve and the hose, and the hose to the flush gun.
- Caution: Do not over-tighten to the point of stripping threads, but ensure a firm, pressure-proof seal.

Phase 2: The Flushing Process

Leverage the high pressure and chemical solvency to scrub the line.

The “Pro Tip” Restriction:
- Crimp the Exit: Use pliers to slightly crimp or restrict the end of the copper discharge line.
- Why? This creates back-pressure, forcing the liquid solvent to fill the volume of the pipe completely (increasing contact time) rather than just running along the bottom of the tube.
Inject Purge:
- Connect the canister to your injection tool. Hold the canister upright.
- Inject solvent in short, controlled bursts based on tubing diameter:
  - Up to 1/2″ Tubing: 10–20 second burst per 50 ft.
  - Up to 7/8″ Tubing: 30–40 second burst per 50 ft.
The Nitrogen Chase (Mandatory):
- Do not rely on the can pressure alone.
- Immediately after the solvent injection, disconnect the Purge canister and connect compressed Nitrogen (set to ~50 PSI).
- Blast Nitrogen through the line. This acts as a squeegee, driving the “plug” of solvent and suspended debris out of the line set.

Phase 3: Verification & Completion

Ensure the line is chemically clean and dry.

Inspect the Discharge:
- Look at the waste container. The fluid will likely look dark/black initially (carbon and oil).
- Repeat: If the solvent exiting the line is not clear, repeat Steps 5 and 6 until the discharge runs clear and colorless.
Evacuation:
- Once the line is clear, pull a deep vacuum on the line set.
- Purge is formulated with a low boiling point to flash off rapidly under vacuum, ensuring no chemical residue remains to contaminate the new refrigerant charge.
Disposal:
- The waste container now holds hazardous contaminants (old oil, acid, sludge). Dispose of the waste solvent in accordance with local, state, and federal regulations (typically in a waste oil container).
