Red Reaper Counter Flow Chiller (PEX / Copper) 9.5mm duotight compatible

🔥 Red Reaper Counter Flow Chiller (PEX / Copper) – 9.5mm duotight Compatible

✅ In stock

The Red Reaper Counterflow Chiller is a high-performance single-pass wort chiller built for fast knock-down and reliable, clog-resistant cooling. It combines an inner copper wort tube with a tough, flexible PEX outer water jacket to deliver excellent heat transfer while staying easy to handle and connect.

🌟 Why Red Reaper?

• PEX-to-copper swaged/soldered joints: a permanent, high-pressure-safe connection — no clamp failures, no leaks.
• Fast, efficient cooling: cold water runs opposite direction to hot wort for maximum heat exchange.
• Low clog risk: larger flow path than plate chillers, so hops and trub are less likely to block it.
• duotight ready: 9.5mm (3/8”) barbs let you connect hoses or camlock setups in seconds.
• Built for real brew days: rugged, stable, and designed to last.

🧊 How a Counterflow Chiller Works

Hot wort flows through the inner copper tube while cold mains water flows through the outer jacket in the opposite direction. This counter-current design lets you chill from near-boiling to pitching temps in one pass, similar efficiency to a plate chiller but with much better hop tolerance.

🧪 What is PEX?

PEX (cross-linked polyethylene) is a flexible, high-temperature, high-pressure plumbing material widely used as a modern alternative to copper. It handles hot/cold cycles well, resists bursting, and makes the chiller lighter and easier to route compared to all-copper designs.

⚙️ Specifications

• Total length: 5.6 m
• Wort path: inner copper tubing
• Cooling jacket: PEX outer tubing
• Inlet / outlet: 9.5 mm duotight-compatible barbs
• Feet: 3 × rubberised feet for stability
• Hanger: 1 × hinged hanger (for easy mounting on kettle handles)
• Fittings: duotight push-in fittings not included

🧼 Cleaning & Sanitising

• Sanitise before chilling: recirculate boiling wort through the chiller for the last 15 minutes of the boil.
• Clean after use: flush immediately, then circulate a suitable alkaline brewery wash (ideally around 80 °C) for at least 5 minutes.
• Reverse flow while cleaning: swap direction a few times to strip stubborn deposits.
• Rinse hot: rinse with clean water at a similar temperature.

⚠️ Care Notes

• Do not store in direct sunlight – UV can degrade PEX over time.
• Avoid long storage with acidic sanitisers – acids can attack copper if left soaking.
• Dry fully before storage for best lifespan.
