Liquid petroleum gas is used by bla. campers gas grill, heating in caravan, refrigerator operation, etc.. Bottled gas is often the cheapest, and most efficient energy.
There are often debates about whether the F-Gas containing oily residues in the gas. Caravaninfo.dk has contacted Alde and gas producers Primagas and Kosangas to examine the need for additional equipment in the form of a gas due oily residues in the gas.
Alde and gas supplier informs ? – See below:
Alde has no requirements for gas filters, but if the gas is dirty or has a lot of oil so it can be put back in the solenoid valve or nozzle which can cause malfunction and stop.
At Truma, there is a requirement that a Truma gas filter is installed to Mono / DuoControl for the guarantee to apply to these.
1) There is nothing in a cylinder filled with Primagaz, der can skadecampingvognens installations f.eks regulator, nozzles for gas-fired boilers, gas, etc..
Gas contained in the bottles in Denmark called LPG – Liquefied Petroleum Gas.
Bottled gas is a propangas, and is the cleanest fuel forsile, known today.
The gas coming from the tuypiske 2 refineries is in Denmark, and a portion of the proceeds from the distillation of crude oil.
The gas may also be recovered from natural gas
LPG sold in Denmark is some of the purest there is in the world.
2) Primagaz sell LPG, and therefore can not answer, it worthwhile to install a gas filter.
3) Primagaz supply also some negotiating at the border, and it is the same gas, which are being sold in Denmark.
There are dealers / fillers in Germany, selling and fills bottles with German gas, which may have a different purity than in Denmark.
Kosangas says there is no oil residue in Danish F-Gas (Bottled).
All cylinders are evacuated before replenishing.
Applying “truckgas” there may be a case of impurities in the gas.
Gas regulator with slangebruds sikring:
Manufacturers selling duo control with associated gas filter, has often campers an idea of, that it was only legally drive with the caravan with gas operation if there were installed eg duo control.
NB. An ordinary gas regulator with slangebruds security to approximately. kr. 150-200,- meets the requirement for, you can run with the gas turned on 🙂 .
Attention is drawn to the "pressure relief valve that vents of a valve by overpressure" - not required by the Danish authorities (safety Agency), as part of the controller, as it has assessed that security would be more disadvantages than advantages it. Moreover, there is already a pressure relief valve in the valve, mounted in the cylinder (DK).
It is often a requirement for valve has slangebruds security, and here, for example Kosan gas's standard valve click-on is with built slangebruds security. F-gas regulator with slangebruds security, works by there is a ball inside the controller at normal consumption is at the bottom, and by abnormally high consumption, for example by line rupture, the gas pressure pushing the ball up so that it closes the regulator. There are also gashøjtryksslanger (with slangebruds security).
Some campers get fitted with a Duo Control Cs gasflaskeomskifter which automatically switches between 2 f-gas bottles, when one cylinder becomes empty it switches over to the other gas bottle. One can connect as additional EisEx for SecuMotion, DuoComfort as the temperature at about 0 ° C can prevent the formation or ispropper propanhydrat of the regulator due to. the traces of water, which occur in the liquid gas – this causes, that the gas supply is reduced or stopped completely.
Duo Control Cs gasflaskeomskifter is smart for people who want happens automatically switching cylinder – But you should not spend money on this additional equipment due “unclean gas”, or if you want to drive with the caravan gas operation, so you do not need Duo Control Cs gasflaskeomskifter.
You do not, to mount such Duo Control Cs to meet the Danish rules, en nyere standard regulatorventil til ca. kr. 150-200 meets the requirement and is with the security slangebruds. You can check if your regulator valve has slangebruds security by shaking it, and the ball is heard.
The picture below is from March 2017:
This is a sample of the above, which can be seen when mounting the above, it is legally, driving with gas lit – An ordinary gas regulator with slangebruds security to approximately. kr. 150-200,- also satisfies the requirement to, To run with the gas turned on :-). Saving approximately. kr. 2.500,-/ 4.200,- In addition comes the maintenance cost of replacing the gas filter.
From our contact with Kosangas, Primagas og Alde, there are no problems with impure gas (oily residues in the gas) 🙂 . We have changed some gas regulators, and have not found oily residues in the gas in the gas hose or regulator m.v…
The conclusion is also, that regularly lead above contact Alde, Kosangas and Primagas can be stated you do not need, To mount the gas filter or other extra equipment.
Just as you do not need, at monterer f.eks Duo Control for, to comply with applicable regulations when towing a caravan with gas operation (gas lit) in Denmark.
An ordinary gas regulator with slangebruds security to approximately. kr. 150-200,- meets the requirement for, you can run with the gas turned on 🙂 .
There are campers who have lived in their caravan up to 1.600 days, and using only LPG gas, without any problems with the oil residue in the gas 🙂 .
In addition, Caravaninfo.dk contacted an advisory special company in the gas and gas filter which informs:
To my knowledge, not normal to use gas filter here - the gas coming from the bottle is clean and if used hoses or copper pipes rest of the way there can not really get bad.
It is an entirely different matter when using black pipe - I have seen before ☹.
Now, if it was natural gas, then it is not up for debate - must always be a filter before the regulator.
Regular check and replacement of gas filter:
The manufacturer of gas filter type bla., the customer should check gasfilterpatronen, each time to switch gas cylinder, and if you as a customer finds droplets of oily residues, clear liquids or white deposits of calcium on the cartridge or filter cup, the cartridge is saturated and needs to be replaced. In addition, it informs, that generally should cartridges “replaced at least every two years”. Replacing the filter cartridges cost per. PCS. that. kr. 162,- seen on the Internet 2017.
This is something the Red Tape, having to turn the felts of every time you have to change the gas cylinder 🙁 . You may use the supplied plastic wrench as in the case of utility / tool – However, do not use tools.
Some places online will be provided, that one should not use the gas installation without gas filter, due to impurities in the gas.
Impurities in the gas will only of use incorrect gas regulators (Using the high-pressure regulator) instead of alm. 3 bar-pressure gas regulators great reduction in pressure cause a chemical reaction, and the gas separator oil. Typically, the campers with Duo Control which has been mounted højtryksregulatorer marked with Unreduced pressure, and which typically is mounted at the same time Duo Control.

NB.For you as a gas filter fitted, you should be aware there have been problems with Truma's gas filter which has led to a risk of gas explosions and injuries as they write – See link on safety message. • Link: Replacing the Truma gas filter – Replacement required filter housing.
