Laboratory R-407C — refrigerant for research, teaching and analysis
Laboratory R-407C from REAL GAZ serves university and industrial laboratories that study vapour-compression cycles and glide behaviour.
As a zeotropic blend of R-32, R-125 and R-134a, it is a good teaching example of non-isothermal evaporation and condensation.

📘 Technical and Handling Notes
Laboratory users should note that the temperature glide is about 7 K, so saturation temperatures differ between bubble and dew points and instrumentation must be set accordingly. Always charge from the liquid phase, ventilate rooms because the gas is heavier than air, and keep records of recovered refrigerant. Pressure at 20 °C is near 11 bar, and thermal decomposition above flame temperatures can produce toxic and corrosive products.
A teaching laboratory benefits from a well-planned experiment series. Students can begin with a basic cycle on a bench refrigeration trainer, observe how bubble-point and dew-point temperatures differ, and then compare coefficient of performance at several evaporating temperatures. A second series may charge the circuit by weight and then by superheat, showing why zeotropic blends need liquid charging. Instruments such as pressure transducers, thermocouples and mass flow meters should be calibrated beforehand. We can supply small refrigerant quantities for course use and advise on a simple recovery and logbook routine that fits an academic environment. Laboratories planning publications should note the lot number of the cylinder in their method section, since this makes the refrigerant source traceable for later readers. Our team can also suggest suitable bench scales and recovery units for small refrigerant volumes.
