How efficient is ENVIRO-SAFE?  AutoRefrigerants.com  (800) 524-5987

Extremely efficient! ENVIRO-SAFE ES-12a is up to 32% more efficient than R-12 and much more efficient than R-134a. This means less wear on your refrigeration system, substantial energy savings and reduced operating costs. With ENVIRO-SAFE the compressor will load approximately 2-3 hp only. ENVIRO-SAFE ES-12a's boiling temperature is -30.4F. ENVIRO-SAFE ES-12a was designed as an R-12 replacement in all R-12 applications.

Is ENVIRO-SAFE safe?

Yes! ENVIRO-SAFE is an "ENVIRONMENTALLY SAFE" organic, non-toxic, non-ozone depleting hydrocarbon compound. ENVIRO-SAFE is a hydrocarbon refrigerant and has been endorsed by GreenPeace. It is in full compliance with the UN Montreal Protocol. Like most organic materials ENVIRO-SAFE is flammable, but its ignition temperature is 1585F at both 5 psi and 0 psi (which is better than the DuPont R-134a's ignition temperature of 368F at 5 psi and 1411F at 0 psi). Nevertheless, a pine odor has been added to the product so that any leak in a refrigeration system can be readily detected. To locate the precise origin of a leak, it is recommended that a hydrocarbon detector be utilized. Most mid and higher priced conventional leak detectors will detect hydrocarbon refrigerants. In the alternative, either soap bubbles or ENVIRO-SAFE DYE-CHARGE can be used. ENVIRO-SAFE DYE-CHARGE is both visually detectable and responsive to black light. In a safety study, the prestigious Arthur D. Little scientists concluded that hydrocarbon refrigerants pose no significant increased risk or hazard over Freon.

ENVIRO-SAFE does not become caustic if contaminated with moisture or oxygen.

ENVIRO-SAFE is covered by OSHA Hazard Communication Standard.

How is ENVIRO-SAFE packaged?

ENVIRO-SAFE is available in cans (12 cans per case), 30lb. cylinders and also 50lb. cylinders.

Does ENVIRO-SAFE require retrofitting?

No! ENVIRO-SAFE is a direct drop-in R-134a replacement. It requires no retrofitting or redesigning of the refrigeration system because it is completely compatible with all the materials, hoses, O-rings, seals and oils (mineral or synthetic) in all systems. The savings can be enormous! If you have an automotive R-12 system you must change the two vehicle fittings to the 134a-sized fittings and properly remove any Freon in accordance with EPA procedures. Changing the fittings can be done easily by screwing on (over the existing R-12 fittings) 134a-sized adapter fittings. All you will need are the two 134a adapter fittings for the vehicle year and make, which should cost around $9.00.  (We have them here ). You DO NOT need the $60 to $80 "134a Kit".

How do I install ENVIRO-SAFE?

There are no new procedures or techniques to learn! The same equipment and gauges are used. The refrigeration system is charged in the same manner as with the refrigerant being replaced using approximately the same pressure levels. (Note: ENVIRO-SAFE ES-12a pressure on the high side may run up to 15 psi lower than what your R-12 high side pressure normally is. The low side pressure should be the same as your R-12 low side pressure at any given ambient temp.) For those who install by weight, the equivalency ratios are: .33 lb. of ENVIRO-SAFE ES-12a is equivalent to 1 lb. of R-12; .38 lb. of ENVIRO-SAFE ES-12a is equivalent to 1 lb. or R-134a; .41 lb. of ES-22a is equivalent to 1 lb. of R-22; .40 lb. of ES-502a is equivalent to 1 lb. of R-502. ENVIRO-SAFE is completely compatible with synthetic or organic oils in all currently existing systems. No flushing or oil changes are required. The only difference is that ENVIRO-SAFE is installed as a liquid.

Does ENVIRO-SAFE have EPA approval?

ENVIRO-SAFE is a zero ozone depleting "second generation" replacement for R-134a and all other substitutes for Freon that are non-ozone depleting. Unlike R134a, it is also non-global-warming .  EPA's Final Rule, issued 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"

If an automotive system is "first generation" (has 134a fittings and contains no Freon ) it may accept a "second generation" refrigerant like ENVIRO-SAFE.

Is ENVIRO-SAFE guaranteed?

ENVIRO-SAFE is guaranteed to be ozone safe and to perform as an efficient refrigerant in all systems. ENVIRO-SAFE is guaranteed to be up to 32% more efficient than Freon. ENVIRO-SAFE is guaranteed not to become caustic if contaminated with moisture and oxygen. ENVIRO-SAFE is further guaranteed not to harm air-conditioning system components or any other related mechanical equipment if installed and used according to factory directions.
