^ Nope, go for a cross-charge bulb... :D
er dont no who trained ya an i dont mean to be rude sorry if i am when i woz 19 all the apprentices thought ooo tevs are all factory set went on danfoss course when they brought out the new tevs with indistructable cappillarys glen more ran it an boy did i look stupid when i said that .All tevs need to be set up no mater what make or who fitted them an if ya dont agree at least check it save ya alot of hassle if ya got a cabinett room or even water chiller that just aint workin rite an it an easy fix oh an yeah its been last thing i checked a few times on new and old systems an it was the problem
After I run through some checks, coils, fans etc, I will look at my TEV. I don't believe that the factory intends for thier setting to be permanent, they don't know what the application will be. I agree that they get it close but they put the adjustment on there to fine tune to your application. Just my opinion.
In 18 years supermarket work i have never had to set a valve superheat unless someone had previously scewed up the setting.
In case design selecting the coil is not only selected to match the case load but also expansion valve ratings.
I know this is an old thread but with me being new to the forum I would like to add my tuppence ha'penny to it.
If your using a drop in replacement refrigerant, you sometimes need to make fine adjustments to the XV. Due to the not quite matched compatability of the dropin to the designed system parameters.
