Frequently asked questions
What refrigerants does the Bitzer W4NA-K support?
The Bitzer W4NA-K is qualified for R717. Capacity values at standard ULT (-60/45 °C), LT (-35/45 °C), MT (-10/45 °C) and HT (-5/45 °C) conditions are listed in the table above for each refrigerant.
What is the cooling capacity of the Bitzer W4NA-K?
Running on R717, the Bitzer W4NA-K delivers 0.03 kW at MT, 0.03 kW at HT. Use the Benchmark tool to evaluate capacity at your exact SST/SDT and superheat conditions.
Can the Bitzer W4NA-K be retrofit to a lower-GWP refrigerant under EU F-Gas Regulation 2024/573?
Open the F-Gas Retrofit tool with this model pre-selected to see drop-in alternatives ranked by capacity match, COP, GWP, PFAS impact, and 2026/2030/2035 phase-out timeline.
What polynomial standard is the Bitzer W4NA-K performance data based on?
Capacity, power, and current polynomials follow EN 12900 (10-coefficient bivariate in SST/SDT) for European-origin brands and AHRI 540 for North American brands. Coefficients are normalized into a common form for cross-brand comparison. Fit your own data in the Polynomial Fitter tool.
