LPG Tank, 37Mb Instead Of 30Mbar

[shawn&emma]

I’ve just fitted an underslung gas tank to my sprinter conversion. The supplied regulator with the kit is a 30Mbar but my existing equipment documents say 37mbar should be used. I've read that the regulations changed around 2002 to the use of 30Mbar for butane and propane.

I run a Junkers water heater and even the ones sold now say 37mbar and the propex heater says a reduced pressure will mean it won’t run to maximum heat output.

The question is can I not just connect my 37mbar propane regulator to the tank outlet (via an adapter) and continue to use the same pressure that’s worked perfectly for the last 4 years.
From what I’ve read the regulator spec says EN12864 standard which says it will work with Butane/Propane and a mix off, LPG.

is there something special about the regulators that run lpg? I’m presuming not as in our RV we use lpg from the onboard tank and then via an extend a stay kit connect up a calor propane bottle, both running through the existing regulator on the onboard tank.

Photo attached of the regulator im looking to use.

Thanks for reading.

Can't you get a proper tank regulator that is 37mb, Basildog will know.

Lots of Keywords misleading potential customers as I can assure you that regulator doesn’t meet any of the quoted standards in the description.
Click on the link and they suddenly don’t get a mention in the item description.
Not suitable for Leisure vehicle use .

As you probably know the Leisure industry converted to 30 mbar regulators nearly 20 years ago now .
No leisure vehicle appliances should now require a higher pressure supply to operate correctly.
Leisure vehicle regulators are also normally at least 2 stage which gives a much more reliable constant pressure outlet than cheap bottle top single stage types ,
It’s also a requirement for the regulator to have a built in over pressure protection device normally operating at around 100 mbar , unlike a bottle mounted single stage or the red 37 mbar 4kg/h someone has suggested, these will fail to full bottle pressure so potentially 2 - 20 bar (66 to 650 times the normal operating pressure)

1.5 kg/h is the maximum permitted flow rate on a Leisure vehicle.
Yes you can get a 37 mbar regulator that will fit a tank but the question really is should you use it ?
We wouldn’t sell it to someone who we know wants to use it for a Leisure vehicle.
