What is the correct suction pressure when charging a true freezer using refrigerant 404a?
frezer not frezing hi side 250 psi low side 45 psi
What is the property of refrigerant 404A?
what is suction pressure of r407a
What should the low pressure be for a 404a refrigerant on a freezer?
18-20psig suction 250-270 psig discharge In freezers pressures are ok .I got it ,but the mention pressure of suction 18-20 discharge 250-270 at what temprature in centegrade it should be.
Can R22 be used with 404A refrigerant?
No, refrigerants cannot be blended.
What should the high and low pressures be for 404A refrigerant on a walk in cooler?
low 50 to 60 and high 250 to 300
What type of refrigerant do you need in a high temp walk in freezer?
Newer freezers compliant to efficiency standards use R-404a. However an older unit may only be able to us R-22 (which will be completely phased out by 2020).

a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.

18-20psig suction 250-270 psig discharge In freezers pressures are ok .I got it ,but the mention pressure of suction 18-20 discharge 250-270 at what temprature in centegrade it should be.
Define a zeotropic refrigerant blend and give an example?
In a zeotropic blend, the blends boil out at different temperature but at the same pressure. typical example is R704
What kind of refrigerant do car cooling systems use instead of freon?
R-404A, R-407C, and R-410A. are the newer, environmentally better alternatives to freon. For complete details and generic names for these substitutes, please visit the site http://www.epa.gov/Ozone/snap/refrigerants/lists/index.html.
