HC-12a, also called ES-12a, OZ-12a, DURACOOL 12a [1] and Hydrocarbon Blend B, is marketed as a "drop-in" replacement refrigerant for R-12 and other refrigerants. HC-12a is a mixture of hydrocarbons , specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting.
1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...
Various fractional sizes are also available; e.g., 2 ⁄ 3 A and 4 ⁄ 5 A. B: U10 336 (Russian Federation) #3 (China) R12 (carbon‑zinc) LR12 (alkaline) 8,350 (alkaline) 1.5: 21.5 × 60 Most commonly found within a European 4.5-volt lantern battery. Not to be confused with the vacuum tube B battery. C: U11 or HP11 (In the UK) MN1400 MX1400 Baby
Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12 , as these systems traditionally use mineral oil , [ 2 ] which HFC-134a does not ...
Equipment Compatibility: Generally compatible with R22 system components, though some adjustments may be necessary for optimal performance. [ 5 ] Environmental and Safety Considerations
Mineral oil used with R-12 is not compatible with R-134a. Some oils designed for conversion to R-134a are advertised as compatible with residual R-12 mineral oil. Illegal replacements for R-12 include highly flammable hydrocarbon blends such as HC-12a , the flammability of which has caused injuries and deaths.
Nothing brings a sense of grounding quite like earthy browns or burgundies. “These tones will definitely make a statement in 2025,” says Kate McGlone, a design expert at Winnings.
The Significant New Alternatives Policy (also known as Section 612 of the Clean Air Act or SNAP, promulgated at 40 CFR part 82 Subpart G) is a program of the EPA to determine acceptable chemical substitutes, and establish which are prohibited or regulated by the EPA. [1]
