50Mbar Gas Regulator info

[tanex]

My old Hymer runs on 50Mbar and as I suspected a duff regulator I sent for a new one.
It arrived today . It is a Silverline 50mbar (german Type) All well until I read the small print. "not for use in Caravan or motorhome" Any idea why not and any tips on where to get one FOR a motorhome?

Hi tanex. As far as I am aware, 50Mbar is no longer used in the leisure industry. Our 99 model Hymer (import) came with a 30Mbar regulator, which covers both propane and butane use.

Cheers,

Jock.

HELLO Jock
No idea when they went from 50 to 30. My Hymer is a 1995 and clearly labelled 50MBar. The Truma boiler,fridge and cooker all run on this pressure. Would rather stick with 50mbar and thought the german made Silverline would do the trick. Just curious why the paperwork says NO to Motorhome use. Dont want to die yet!!!

Probably because then changed to 30mb in 2002 so a recently made 5Omb regulator would not consider suitable for use in a Motorhome or caravan.

I assume that the restriction is due to newer motorhomes having kit in that may NOT run on such a high pressure. The 30mb regulators were brought in to allow equipment to run on both butane and propane and standardise it at one level at which both would work okay (I think one is 37mb and the other 28mb from memory but don't quote me!). To cover themselves they are probably saying it's not for caravan/motorhomes so no-one tries to use them in a system not originally designed for them.

I'm sure I had one that said the same on my old Dethleffs, used it for years. A regulator is a regulator?

 

[tanex]

Its going in!
Thanks to all

I agree that the 30mb regulator was introduced as a compromise between the old 37mb for propane and 28mb for butane, but it was probably not implemented in 2002(although rules may have been agreed then) as our 2003 MH has the 37mb regulator which attaches directly to our propane bottles, both Gaslow and Calor.

The gas jets in a more modern motorhome are not suitable for 50mb hence the warning.
Your jets ARE suitable and appliances are designed to run on 50mb.
The warning is for newer vans.

The regulators may be different for your part of the world. If your Hymer is the one as your avatar it is certainly not old enough to have a 50mB regulator if sold in Europe.

Hello
Clearly labelled in a number of place..On flap where gas bottles go and on the C3400 Truma that I rebuilt. Have installed the new regulator and all working as it used to. Here is a photo of gas door flap.

I have the same gas locker, as yourself, but with the 30Mbar sticker, and the boiler is the later C6002, so at some stage between 95-99, they changed from 50Mbar to 30Mbar.

@tanex. I'm pleased that you are sorted.

Cheers,

Jock.

Thank you jock
We bought it without kicking the tyres from a chap in Germany via the internet flew over and drove it to the UK and after a trip up to Scotland had it shipping to the bottom of NZ. I know almost every inch of it and when we do use it we find it perfect for our needs. Installed the Regulator. All working well. Off to Auckland.
