Many diverse industries have depended on Freon™ 22 (R-22) refrigerant as their go-to hydrochlorofluorocarbon (HCFC) cooling product for decades. It's been the most widely used choice for air conditioning (AC) and medium- to low-temperature commercial refrigeration because of its dependability—and because it works. NU-22B can be used to COMPLETELY replace R-22 refrigerant in new or existing R-22 residential and commercial air conditioning systems as well as non-flooded evaporator chillers. Cannot be added to R-22 unless fully evacuated and recharged with NU-22B. NU-22B® Replaces R-22, R-407C, R-422D and R-417A. NU-22B is the only R-22 …An R-502 Replacement for Limited Condensing Capacity Systems. Freon™ 408A (R-408A) refrigerant is a hydrochlorofluorocarbon (HCFC) option designed to replace the hydrofluorocarbon (HFC) refrigerant R-502. Older systems with limited condensing capacity, and low- or medium-temperature commercial refrigeration systems used in …Medium Temp – 5-10°F. Low Temp – 4-10°F. Some ice machines and other specialty refrigeration may be as low as 3°F of superheat. When setting the superheat on a refrigeration system with any type of metering device, you often must get the case/space down close to the target temperature before you can make fine superheat adjustments.Carbon dioxide, CO2, is a colourless and odorless gas. It is relatively nontoxic and noncombustible, but it is heavier than air and may asphyxiate by the displacement of air. When CO 2 is solved in water, the mild carbonic acid, is formed. Cooled CO 2 in solid form is called dry ice. Values are given for gas phase at 25oC /77oF / 298 K and 1 ...Nonflammable and with low toxicity, the direct replacement Freon Hot Shot™ 2 provides other benefits, including: Compatibility with mineral, alkylbenzene, and POE oils. Zero ozone depletion potential (ODP) Widespread availability. Regulations on the long-term use of refrigerants vary by region and application, and may change over time. Well under 5%. ICOR international's NU-22B (R422B) and Honeywell Genetron 422D / DuPont Isceon MO29 are made of same ingredients, but the proportions are a bit different. R422D tends to have a higher pressure than 422B. Both DuPont and Honeywell suggests 422D for low and medium temperature refrigeration use.
