High side can be caused by restricted or blocked condenser coil, or fan not working. Or air in the system.

What is the gas pressure on both compressors on subzero 321


The pressure of the refrigerant in the systems vary depending on the temperature of the refrigerant gas and the type of gas used. So this is a question that can't be answered without a lot of additional information.

I have a Traulsen walk threw refrigerator Im getting a high pressure of 600 and a low pressure of 80 and cant get it to cool down, do I need to pull the system down or try something else


Hi side is too high. Look for a condenser plugged with refrigerant oil or the fan not spinning up to speed. If it was serviced recently there could be air in the system or a flake of copper oxide clogging the orifice tubes in the evap.

@50/300 I assume it's a med. temp R-22 pump down walk in. Head pressure sounds a little high, probably been overcharged to compensate for a restriction in the metering device (or malfunctioning TXV). Check the solenoid (if pump down), metering device, and filter driers first. If that fails, lineset restriction or non-condensables/water in the charge would be next on my list.

What should the pressures on the low and high side of the air conditioner read ?


low side should be about 30 psi at idle speed, high side 120 to 180 psi depending on ambient temp. higher temp, = higher pressure, as you increase engine rpm to say 1000 low side should drop to 10 to 15 psi & high side should increase about 30 psi. If high side goes over 280- 300psi you have contamination (air) in system or over charged with refrigerant. you will need to recover freon, evacuate & recharge system with proper amount of refrigerant. If the low side drops below 0psi or into vacuum then the refrigerant level is low, you will have to check for leaks , repair leaks & refill refrigerant.
Hope this helps

Traulsen ur 48 dt freezer want go below 10 deg


The first place to look is to check the charge. Using guages check the low and high side pressures and their relationship to one another. I'm assuming your unit is a R-404 unit which, if fully charged and the condenser is clean, and the fan is operating, should have about 210 to 250 high side pressure. Other things to check: evaporator coil ice/frost free; defrosting properly to obtain a clean coil; all evaporator fans running. If low side pressure is above 30 PSI you have a weak compressor. Whatever, fix the Traulsen unit, its head and shoulders above anything else on the market today.

The cap tube is clogged and the unit is overcharged. Get used to this on beverage air units.

Low suction pressure high head pressure


That system has a restriction. Most common at TXV valve or capillary tube. Will need to be replaced by Refrigeration company. In this video I replaced TXV valve and filter drier due to the same issue You have. Its Ice Machine, Low side was at 5 PSI, High at 250PSI : 404A; should be around 55-65 Low; 250 -275 High. Replaced drier and TXV, machine works proper.
