Yeah I know, my original comment about vents was relating to the above image, before I realised it was just a stock image. My copper cab has vents but only 2 small ones on either side where as cabs with active equipment in them seem to have considerably more Agree that if it has no sticker and is directly connected then it most probably is just an extension for more copper cables.

Apologies for the late reply.

Yes, it is connected via 2 tubes (i think) but i have only seen it from the back.

I will take a picture tomorrow.

Thanks for confirming. In that case it's definitely an extension for more tie pairs.

Well, for the past couple of days, every time i have driven by, there has been a BTOR van parked right in front of it, however, i have noticed that the door does not have the yellow sticker on it, so as suggested, i guess it is just an expansion unit to take more capacity?

This look familiar, Sir?

No, don't read anything into vents.

Agreed, but...

Normal copper cabinets are usually vented.

No they aren't!

The old cast iron ones weren't, the fibreglass ones weren't, the pre-modern ones might have had had couple of vents in the side, and the most modern ones have no vents at all.

My PCP is about 7 years old and has two small vents at the bottom on both sides of it.

Yeah one type (out of 17) here does as well, but most don't. I don't know who decided to put vents at the bottom of early-90s PCP cabinets, as heat rises, and there are no fans or a build-up of heat at any particular point in a PCP cabinet.

Its direct predecessors (the fibreglass ones) would have actively insulated the internals, and the older and newer ones have no vents.

That what I was thinking. Maybe they've added a second cabinet, but they don't have enough numbers to warranty a full size.
