What is Maxi-Frig?

Maxi-Frig are refrigerants that were developed as an effective replacement for non-ozone-depleting substitutes for CFC-12, CHFC-22 and R502. They have a zero ozone-depletion-potential (ODP) and a negligible global-warming-potential (GWP), which makes it the most environmentally sound refrigerant on earth.

Does Maxi-Frig Require Retrofitting?

NO! It is a direct drop-in replacement. It requires no retrofitting or redesigning of a refrigeration system because it is completely compatible with all the materials and oils (mineral or synthetic) in all systems. The savings can be enormous!

How Efficient is Maxi-Frig?

Extremely. It is up to 30% more efficient than CFC-12, and far more efficient than HFC-134a. This means less wear on your refrigeration system, substantial energy savings, and reduced fuel costs.

How is Maxi-Frig Installed?

There are no new procedures to learn! The same gauges are used, and refrigeration systems are charged in the same manner used with the refrigerant being replaced. Maxi-Frig is completely compatible with the synthetic oil used with HFC-134a and the organic oils in CFC-12 systems. No flushing or oil changes are required.

Does Maxi-Frig Offer Other Benefits?

Yes! Many. Maxi-Frig, unlike other new refrigerants, does not become caustic when exposed to moisture or oxygen and is therefore not corrosive to the aluminum parts in today's systems.

Maxi-Frig refrigerants are better conductors of heat, require less energy to compress, have lower operating temperatures increasing compressor life.

Maxi-Frig refrigerants operate at normal low head pressures, advantageously paralleling R12, while with other new refrigerants the head pressure is generally noticeably higher.

Maxi-Frig refrigerants are more soluble, absorbing oil better resulting in better lubrication than other refrigerants.

Maxi-Frig refrigerants produce negligible copper plating and coke formation on valves, and extremely low chemical breakdown.

Maxi-Frig and EPA Regulations?

EPA'a Final Rule, published April 1, 1994 states:
In this final rule, the Agency has determined that second-generation replacements, if they are non-ozone depleting and are replacing non-ozone depleting first generation alternatives, are exempt from reporting requirements under section 612.

Is Maxi-Frig Guaranteed?

Is Maxi-Frig Guaranteed? Maxi-Frig is guaranteed to perform as an efficient refrigerant in all systems and are not to harm any refrigeration system components or other related mechanical equipment if installed and used according to factory directions.
