Are 407C and R22 pressures the same?
(10) informed that R407C had higher pressures than R22 with discharge pressure of R22 being at 2193 kPa for the lower outdoor conditions and 2784 kPa for the higher outdoor conditions. For all operating conditions, the discharge pressure of R-407C is varied in the range 11-13% higher than R22.
What is the condensing temperature of R-407C?
That fact explains why compressor manufacturers limit the condensing temperature for R407C to around 145–150°F (60°C–65°C) whereas for R134a compressors, the top limit for condensing temperature is 158–175°F (70–80°C) for air condi- tioning applications.
IS 407C a low temp refrigerant?
Freon™ 407C refrigerant performs similarly to HCFC-22 under evaporator temperatures ranging from –7 to 10 °C (20 to 50 °F). It is designed for use in new equipment and as a service refrigerant for existing HCFC-22 air conditioning, heat pump, and medium temperature refrigeration equipment.
Can you use R22 gauges for R407C?
Yes, gauges measure pressure and R22/R407c can be measured by the same instrument unlike R410a (with higher pressures probably needs a wider range gauge). What you should not use is the temperature scale.
Can I top off R22 with 407C?
Mixing R22 with R407C According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
What are normal pressures for 407C?
R-407C PT Chart
| Temp (F) | Temp (C) | Liquid Pressure (PSIG) |
|---|---|---|
| 86 | 30 | 182.38 |
| 89.6 | 32 | 192.86 |
| 93.2 | 34 | 203.74 |

What are good pressures for 407C?
How do you charge 407C?
As with any other refrigerant blend, when charging equipment with Freon™ 407C, remove liquid refrigerant from the cylinder to charge the unit. Returnable cylinders containing Freon™ 407C are equipped with liquid and vapor valves.
HOW MUCH IS 407C refrigerant per pound?
On average, Refrigerant 407C price ranges between $4 and $7 per pound.
What is the suction pressure of 407C?
If this is so always evaporating above zero, 4 or 5 deg celcius, R407c will have a low pressure (suction ) of about 50 psi. and a high pressure ( discharge ) of about 280 psi, which is about 55 deg celcius, cooling cycle.
