What Freon Is Compatible With R12?

What Freon Is Compatible With R12? There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant. Is R12 and R134a compatible? R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to

How Does A Cascade System Work?

How Does A Cascade System Work? A cascade system uses one refrigerant to condense the other primary refrigerant that is operating at the desired evaporator temperature. This approach is usually used for temperature levels less than −80°F, when light hydrocarbon gases or other low boiling gases and vapors are being cooled. What is a cascade
