RX-3N1 vs BG CT2: Coolant Exchange Machine Comparison
This RX-3N1 vs BG CT2 comparison covers power source, capacity, weight, and process method for these coolant service machines, based on each manufacturer’s published specifications.
Bottom line: the RX-3N1 runs on shop air, while the CT2 runs on 12V DC power. The RX-3N1 completes a full exchange through a single tube in 7 minutes; the CT2’s in-loop, pump-assisted method averages 5-10 minutes depending on the vehicle. At 78 lbs, the RX-3N1 is also lighter than the CT2’s 92 lbs.

Why the Single-Tube Exchange Design Matters
The RX-3N1 does removal, flush, and fill through one tube, which means less hose to manage and fewer connection points that can leak or fail. Running on shop air instead of 12V DC also means no motor or circuit board in the exchange path to maintain.
At 78 lbs, the RX-3N1 is also lighter than the CT2’s 92 lbs, which matters when a tech has to move the machine between bays during a shift.
Family-Owned, and It Shows
Engine Clean has been family-owned since 1989, but that doesn’t mean we’re stuck in our ways. We’re tech-forward and run the same modern tools and professional support infrastructure you’d expect from a large company — we just don’t have the layers that come with one. When you call us, you get a real person, and that person can actually fix your problem, not a case number in a queue at a public company or a private-equity-owned brand. If something goes wrong with your RX-3N1, one call or email gets you a direct answer.
