Wine Cooling Unit Refrigerant
In an ongoing effort to offer customers green options for wine storage, Wine Cellar Innovations’ Winezone cooling units now run on R-422B refrigerant. Approximately 2-5% more efficient than R-22 refrigerant, R-422B is ASHRAE designated and safety classified A1. It is non-ozone depleting and has a low global warming impact.
R-422B is compatible with all standard refrigerant oils, so no oil change is necessary. Additionally, it does not require special metering devices or filter driers. Its operating characteristics are similar to R-22, which enables units to experience similar operating temperatures and pressures over a broad range while having less environmental impact. Stocked at distributors nationwide, R-422B refrigerant has low discharge temperatures conducive to long compressor life.
Winezone cooling systems also feature the flexibility to run on two other alternate refrigerants, R-427A and R-438A. When using either of these two refrigerants, it is necessary to switch to POE oil instead of mineral oil, which is used with R-422B.
The WineZone refrigeration systems run on R-422B (NU-22B®) which has the following benefits:
- It is about 2% to 5% more efficient than R-22
- ASHRAE Designated and safety classified A1: Nontoxic/Nonflammable
- EPA Snap Listed
- Non-Ozone Depleting
- Low Global Warming Impact
- Compatible with all standard refrigerant oils so no oil change is necessary
- Has R-33 like operating characteristics so units will have similar operating temperatures and pressures over a broad range.
- No need for special metering devices or filter driers
- Low discharge temperatures conducive to long compressor life
- Stocking Distributors Nationwide
In addition the WineZone system is flexible enough to run with these alternate refrigerants as well:
- R-427A (Forane®)
- R-438A (Isceon® MO99™)
When using the R-427A or R-438A you are required to switch to POE oil instead of mineral oil as is used with R-422B.
