Frequently asked questions
What refrigerants does the Dorin CD 1200M support?
The Dorin CD 1200M 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 Dorin CD 1200M?
Running on R744, the Dorin CD 1200M delivers 22.65 kW at LT (-30 / -5 °C), 35.89 kW at MT (-5 / 25 °C), 22.23 kW at HT (-5 °C evaporating, transcritical gas cooler). 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 Dorin CD 1200M?
DigiEntropy classifies the Dorin CD 1200M as CD 400. Browse the Dorin catalog to compare nearby models from the same brand.
Can the Dorin CD 1200M 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 Dorin CD 1200M performance data come from?
From Dorin'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.
