Wotcha folks... been chattin with Phil for a few days and was asked if I could post some pics of a naked prommi...
Well, there is only one bit that needs showing as everything else is visible in the base box... & that's the ThermalBus Assembly. The thick black hose that leaves the basebox and has the evaporator head at the end that goes on your CPU.
The ThermalBus contains the suction line and capillary tube. The suction line runs from the compressor to the evaporator head, and the capillary tube runs from the drier at the condenser to the evaporator head.
Refrigerant is pushed under high pressure thru the condenser, thru the drier and up the capillary tube to the evaporator head, where it is then sucked down the suction line and back to the compressor.
Here you can see the evaporator head and flexible suction line, and the shell of the evaporator casing...
This is hidden beneath a layer of black nylon braid and armaflex insulation. The capillary tube spirals around the outside of the suction line, which allows the suction line to cool the capillary tube.
The flexible suction line itself is the only real weakspot any Prometeia system has... altho this has been much improved in the later MkII ranges, in the early MkI range tears were frequent...
Also, spiralled up the thermalbus, between the armalex and the braid, you can see two sets of wires. One is the PT100 thermal probe that provides your evaporating temperature...which is usually mounted to the side of the evaporator head just below the exit to the suction line...
and the remaining wire (the most visible one that you can see thru the braiding) leads to the heaters within the head that are there to prevent condensation...
All together there is approximately 2mtrs of capillary tube on a MkI unit...
You may also see units out and about that look slightly different... these are modified rigs that have often had suction line damage. When the suction line has torn as shown above in the post, the only real solution is to replace it. The leak cannot be "patched" on the flexible section... following shows the replacement suction line that I tend to use when repairing units, which can withstand brutal punishment and some really tight bends...
Unfortunately in some cases, the head must also be replaced... but this is in no way a bad thing. The common replacement head on the market is the Baker18 head... which offers a fair performance increase due to a larger internal surface area of refrigerant to copper... which allows for more solid stable temperatures with less fluctuation.
