CrystalEvery bullet restricto-cap box comes with a table. Ask your supplier if you can look at one.

what is the meaning of LBP and HMBP respectively? why does the table show that the return gas superheated up to 35 °C ? I think this temperature is too high, am I right?
looking for your return.

LBP stands for Low Back Pressure, freezer applications

HMBP = High Medium Back pressure : Cooling and AC application.

Lbp >Low back pressure
HMbp . High / medium back pressure
I think the chart maybe should have been in degrees F more like 35 F
