AutoFrost-X4 (GHG-X4) Features

ASHRAE pending R-number & safety classification: R-414A A1/A1

Substitute for R-12 in almost all cases (R-500 in most instances also)

NO OIL CHANGE required - uses standard R-12 mineral oils or AB

US EPA SNAP "acceptable" for most all stationary/transport (cargo) refrigeration NOW

EPA acceptable NOW for Cars (MVAC) use. EPA has reviewed the application and found R-406A acceptable for automotive use subject to "use" conditions (unique fittings, barrier hoses, etc) Published in the Federal Register Oct 16, 1996. Text or Adobe Acrobat (PDF) formats of this final rule from the EPA homepage. GHG-X4 (AutoFrost/Chillit) and GHG-HP are also included in this final rule.

NO CFCs - formula by weight %: R-22/R-142b/R-124/R-600a 55/16.5/28.5/4

Technical help - 1-888-AUTOFROST (1-888-288-6376). Ask for code 10 [service provided by MEA]

NONFLAMMABLE, even after leaking. UL classified "practically nonflammable" (same as R-22)

Performs equal to or BETTER THAN R-12.

Question and Answer sheet for Autofrost-X4

GHG-X4 initial thermodynamics and other technical info.

About 95% less Ozone Depleting and 88% less Global Warming than R-12 R-406A ODP is 0.0553 (per pound) or 0.0442 (per system, only 80% as much as R-12 is used). R-12 ODP is 1.0. GWP is based on halocarbon GWP, 100 yr ITH.

MUST be charged into system as liquid to prevent composition change

CANNOT BE VENTED (in the USA) - must be recovered (contains HCFCs)

DO NOT USE IN R-134a systems. PAG or Ester (POE) oils may be destroyed.
