looking for a little help. Im working on a 10 ton trane hot gas reheat morginizer. When the unit starts suction pressure drops so low it opens the lps and the unit shuts off with in 5 second pressure goes back up and unit fires back up it will do this until compressor gets so hot it opens the overload. The liqiud line filter was freezeing on the evap side up to the txv so i changed both thinking i had a restriction no change. Charge is right on with the name plate i was wondering with the added coil on this unit could name plate be wrong and im under charged. suction line is warm at compressor head pressure is about 180 psi all fans are working.
I asked because a few years ago Trane used spun copper driers that liked to puke out the desicant beads into your system, plugging every orifice. If it was a steel body drier, you have a solid core so no worries there. Never seen a morganizer, what's that some kind of proportional hot gas reheat? Dehumidification?
Morganizer is a customized unit, it may need charge tweeking, give her some gas watch your S/H and S/C, discharge temp, coil temp delta T and see what it does, weigh what you put in, as you put it in.
It's hard to stop a Trane. but I have made one helluva living keeping them going.

Morganizer is a '' customization'' company. they add ERV's, Hot water coils, Hot gas re-heat you name it. they take a Trane package unit add the element of an engineer's brainstorming and put it together, sometimes a tech's nightmare is the end result, of course isn't that what alway's happens when you put an engineer in the equasion/

Yea its the first for me it has a another coil that sits under the unit in the supply duct that the discharge goes through before it goes to the condenser. It has louvers that open and close on the coil. I changed the dryer and txv i dont know if the beads could have got in the feeders on the other side off the txv.

180 head pressure is low. I'd do as Southern Mech suggests and see what happens...
