How'd He Do That?
A quick and deep evacuation of an AC or refrigeration system simply comes down to correct practices - including proper installation, and assembly, keeping the moisture out during fabrication and, of course, the right tools, hoses and gauges to measure the level of degassing and dehydration.
When moisture (liquid) enters a system or condenses, the only way it can be removed is in a vapor. When it comes to evacuation only small amounts of moisture are practical to remove this way. "It is not practical to remove large amounts of water with a vacuum pump as boiling water produces large amounts of water vapor. 1 lb of water (about 1 pint) produces about 867ft3 of water vapor at 70ºF." (1) Therefore in the words of David Boyd at Appion, "Keep it clean dry and tight".

"If you can't buy it, build it, and that's what we did!"
A proper and quick evacuation requires the right hoses, connectors, assembly lube, core tools and a quality micron gauge. The problem is none of these components are available in a single kit from a single manufacturer until now. We went back to the basics, if you cannot buy it build it, so that is exactly what we did. The TTT evacuation rig contains all of the hard to find components required to evacuate systems in record times plus specialty plugs and fittings to keep things clean and easily adapt them to any vacuum pump.
What makes this a great evacuation rig?
- Eliminates as many fitting as possible.
- Allows you to pull vacuum cores during evacuation
- Uses large diameter hoses for evacuation and evacuates from both sides of the system
- All components are vacuum rated, tight and properly assembled.
- Makes provisions to isolate the evacuation rig for pressure rise testing.
- Keeps everything clean dry and tight.
