450 psi / 35 psi
low side 25 psi high side 125 psi
The high pressure side of a freezer compressor typically ranges from 200 to 400 psi, while the low pressure side ranges from 10 to 30 psi. These pressures can vary depending on factors such as the type of refrigerant used and the temperature inside the freezer.
The refrigerant pressures are dependent on the type of refrigerant.
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.
Refrigerant should be added through the low side of the system. This is typically done while the system is running, as adding refrigerant through the high side can be dangerous due to high pressures. It is important to follow manufacturer guidelines and use proper equipment when charging a refrigeration system.
The recommended high pressure for 404A refrigerant in a walk-in cooler is around 250-300 psi, while the low pressure should be around 50-65 psi. These values may vary depending on factors such as the ambient temperature and the specific system design. It's important to consult the equipment manufacturer's guidelines for precise pressure recommendations.
If the pressures are always equal running, the compressor is bad and would need replaced
Manifold gauge/gauges are used to check both the high and low side pressures of the refrigerant inside the a/c system...................

because it can kill you!!!
near-azeotropic refrigerant blends all exhibit some .A )temperature glide and fractionation .B)oil problems .C) high boiling points .D)low condensing pressures
Too much refrigerant can do it, yes. System pressures get extremely high on both sides of the AC system when it is overcharged.
