Frequently asked questions
What refrigerants does the Frascold A2-4SK2 support?
The Frascold A2-4SK2 is qualified for R744. The table above lists capacity at ultra-low, low, medium and high temperature duty for each refrigerant, with the evaporating and condensing temperature each value was calculated at. Those conditions differ by refrigerant, so read them per row.
What is the cooling capacity of the Frascold A2-4SK2?
Running on R744, the Frascold A2-4SK2 delivers 5.51 kW at ULT (-40 / -10 °C), 8.21 kW at LT (-30 / -5 °C). These are calculated cooling capacities at the rating basis the manufacturer declares with its data, not measured values. Use the Benchmark tool to evaluate capacity at your exact SST/SDT and superheat conditions.
What type of compressor is the Frascold A2-4SK2?
DigiEntropy classifies the Frascold A2-4SK2 as SK Series, for CO2 subcritical. Browse the Frascold catalog to compare nearby models from the same brand.
Can the Frascold A2-4SK2 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.
Where does the Frascold A2-4SK2 performance data come from?
From Frascold's own published performance data, evaluated at the suction and liquid conditions the manufacturer declares with it. Which rating standard the manufacturer certifies to (EN 12900 or AHRI 540) is not stated on this page; check the manufacturer's datasheet. Fit your own data in the Polynomial Fitter tool.
