Facts about LPG (F-gas):)
Liquid petroleum gas is made up of the two gases, propane and butane;. In the cylinder is pressurized and compressed to a liquid state, evaporates, When opening the cylinder valve.
The pressure in a gas cylinder is 4-14 bar (high pressure) - Depending on the temperature and gas.
When the gas is released through a regulator, it has a pressure of approximately. 30 mbar (low pressure) – That's what gastryk, as ordinary gas accessories sold in Denmark is designed to (see rating plate on the gas equipment).
How many kWh / MJ (energy) equivalent 1 kg LPG for……?
1 kg gas corresponding to 13,95 kWh.
1 kg gas corresponding to 50,2 MJ.
How many liters are 1 kg LPG……?
1 kg gas corresponding to 1,972 liter liquid gas.
NB. Connected gas bottles regarded as operating means and not as dangerous goods
(ADR exemption acc. section 220.127.116.11 and 18.104.22.168. e).
Which gas valve, use of driving gas operation:
It can be very, To find out which gas valve you should use and what is legally.
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.
You do not need to mount Duo Control Cs to meet the Danish rules, A recent standard regulator valve below kr. 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.
NB. The old model regulator could be slipped around plastic locking ring at the valve, which cause not allow sufficient pressure through the valve.
If you press down with your hand on the valve and comes max pressure, it is because it is faulty (Been lax about plastic locking ring).
The flame blows out when driving with the fridge on gas operation:
When you buy a caravan expect most to be able to use the opportunities the caravan is sold, such that you can drive with the caravan gas operation. Gas operation of the refrigerator provide the best cooling effect.
When driving with the fridge on gas operation are the gas flame blown out while driving in some caravans. There are some indications for each of the 2 leading manufacturers of absorbent fridges. If the gas flame being blown out nothing happens, due to the gas supply disconnects (Solenoid valve / heat protection) – However, please note on the refrigerator loses cooling effect.
There are many theories about the cause of the gas flame being blown out while driving, in winter is often vinterafdækninger mounts on both refrigerator grates, why the problem does not occur in winter when vinterafdækninger
is mounted. In summer you can use the lower refrigerator grate when driving with the fridge on gas operation, but use only the lower. The lower winter covers as used in the summer should be removed as soon as you are promoting on dinistationen / campsite.
The refrigerator is vented via the 2 external ventilation grates, where the lower grille pulls fresh air into, and when the fresh air coming from the lower ventilation grill heats up, after which the heated air coming out of the top vent grill (called chimney effect).
Using the refrigerator in winter:
If you use the refrigerator, when the outside temperature is below 8 ° C, should be fitted vinterafdækning on ventilationsgitrene. Winter cover protects your refrigerator against the cold air.
Some caravan dealers inform their clients who have problems with the gas flame is blown out while driving, that they must mount a winter cover on the bottom refrigerator grate when towing a camping gas operation in summer, and a winter cover is not included with the purchase of caravan. If you fit winter covers on “summer” you should have your dealer, To confirm this is according to the requirements you are mounting a vinterafdæknings grate (only the lower summer) when driving with the fridge on gas operation.
It is not clear from the caravan manual to be used winter covers on the bottom refrigerator grill in the summer when driving with the fridge on gas operation.
Some Danish caravan dealer reports caravan owners who have problems with the gas flame goes out during a run, that one must not run with the fridge on gas operation while driving, and thus their problem solved.
There are also gasflammebeskytter sold as an option, you may wonder why such a small cousin is not mounted from the start when building caravan. Most campers expect when purchasing caravan, allow its use 12 volt and gas operation of the refrigerator while driving with caravan.
The two leader in the production of absorbent refrigerators are Dometic and Thetford, producers supply bla. Their refrigerators for the respective factories which builds caravans. Cooling munity producers have some requirements for installing the refrigerator, and caravan manufacturers must comply with these requirements when installing the refrigerator in the caravan, otherwise it may not work as it should, and the warranty may want. lapse.
The cause of your refrigerator gas flame blows out when driving can bla. Be:
• Improper installation of the caravan factory.
• Too much air enters and blows the gas flame out.
• Some would say it depends on which side your refrigerator is placed in, but experience shows it is not fair, the problem occurs regardless of which side your refrigerator is located in - Like caravan owners with roof ventilation also experienced the problem.
Many refrigerators are mounted so, that the lower ventilation grill is positioned higher than the floor of the caravan, typically due to the wheel arch.
When the caravan factory install the refrigerator at the wheel arch and ventilation grate is raised above the floor of the caravan, must be drilled in 40 mm hole in the caravan floor cf.. refrigerator manufacturers. The hole in the bottom is “alone to remove any. unburned gas behind the fridge, as the gas is heavier than air,, therefore, any. explored the burnt gas will be at floor level. Caravans which has lower ventilation grating equal to floor level, need not have a hole in the bottom, due to the lower ventilation grille would act as ventilation of the refrigerator and remove unburned gas.
The problem is, the caravan factories may not fully comply with the installation requirements from refrigerator manufacturers. Try to gauge whether the hole your caravan is at the bottom is 40 mm, Maybe you measure 56 mm long cable since heat is used because it has the material in advance.
The gas flame blown out by driving gas operation, might be due to the hole in the base is too great, and thereby comes form their own air / air up to the gas flame being blown out.
Do you run the refrigerator on gas operation - See answer further down.
Do you drive with the caravan gas operation:
What are the rules:
There is no prohibition, driving with his fridge on gas operation while driving, but in some places it is forbidden to have turned on the gas. For example. at gas stations, garages, on ferries, by ferry berths.
There is no requirement, that caravan gas systems should be inspected regularly, but Safety Authority recommends, the plant will be checked at least every two years.
Typically, it is apparent from the operator's manual: The gas system must check regularly according. applicable regulations by a qualified professional.
What is written in the manual (Excerpts from a “caravan manual”):
The gas system was installed and approved in accordance. from “Technical rules for devices with liquid gas and fireplaces in vehicles” (TRF). By changes of any kind on the gas system after the caravan disclosure lapses validity of the supplied gaskontrolattest and control plate on the caravan.
• In addition to the guidelines below you should always observe
operating instructions for the built-in gas appliances.
• The operating instructions must always be available in
• The gas system must check regularly acc. applicable regulations by a qualified professional.
• The gas system must be checked at least every 2. year at a specialist workshop. It also applies to non-registered vehicles. Observe local regulations.
• Close the throttle and the gas appliance gas taps before you run out.
As stated in the booklet supplied with your caravan you must always observe the operating instructions for the built-in gas appliances. This means you need to look in the manual on your refrigerator such Thetford or Dometic. Can not find your user manual, you can often find the manufacturer's website, we have inserted links further down the page.
Why use the fridge on gas operation while driving:
• Refrigerator gas operation has greater cooling effect.
• Gas operation on the refrigerator while driving instead of 12 Volt leads you greater køleeffekt. Using 12 volt consumer your car more fuel and using a bit of engine power for charging power to the refrigerator.

Radiator your refrigerator is not properly?:
If you have problems with your refrigerator does not cool efficiently enough, there are several things you can do to remedy the problem:
1) Do not have the fridge on gas operation, you tried to connect the gas operation as your refrigerator is the most efficient gas operation.
2) You can disconnect it “top refrigerator grill outside” while you are stationary at the campsite.
3) Make sure not, keeping køleskebet open for too long a time so cold in kølskabet comes out.
4) You can decrease the cooling power so køleskebet is on 2/3 setting the max.
5) You can mount the small fans behind the exterior refrigerator grill.
See the links below concerning some examples – The fan behind the refrigerator grate outside:
Radiator your refrigerator properly on 230 volts power but ikke on gas:
Radiator your refrigerator properly on 230 volt power but not gas operation can be caused by poor combustion, and you can take the baffle out which is a winding spiral which sits down in “chimney” since it can also be blackened to prevent and correct draft.
The chimney can also be good to sooty, you can clean the chimney compressed air or for example a bottle purifier, then you blow clean with compressed air.
The burner can also be closed by the soot (fastbrændt), allowing for the burner should be cleaned, try using compressed air, but not directly on the burner.
Remember the 2 leading manufacturers providing 3 year warranty on their refrigerators.
Conclusion on the gas flame blows out when driving:
* Domitec type in their user manual you can drive with the refrigerator and heat the oven to gas operation.
* Thetford write other hand one must not run with the refrigerator and heat the oven to gas operation. Having contacted Thetford informing the not recommend using the fridge on gas operation while driving, but that it can run on gas operation while driving.
* The legislation has not given ban, the caravans running refrigerator or heat the oven to gas operation.
* It is not clear from the caravan user manual, to be fitted winter cover on the lower grill in the summer when driving on gas operation – Just as it is not shown in refrigerator manufacturers' instructions, Therefore, you should get documentation from your dealer on you must install winter grate summer when driving on gas operation (for the sake of any. liability / warranty).
* There are cf.. one refrigerator manufacturer a flame protector to remedy the problem of the gas flame blown out by driving gas operation, why there may wonder, such widget is not mounted from the caravan factory or refrigerator manufacturer. Several campers have the problem and rectified typically campers are told to buy a winter grate to be installed when running on gas operation, or being informed you may not use the fridge on gas operation while driving – But is it fair??, enter any. your comments at the bottom of this page.

How much gas do had with the caravan and in your awning:
You can have a maximum of two bottles of 11 kg in trolley. And it only one of them will be in use (in plant). In the awning must also have two bottles, one of which must be in use (in plant). That means, you must have maximum four bottles of 11 kilo, two of which are in the reserve. source Security Board
The new compressor refrigerator is definitely worth considering if the opportunity presents itself, for example, by carriage returns:
Isotherm has developed a compressor refrigerator for caravans, this very special fridge for camping use is called XL Freeze, and is a revolutionary news for camping.
The fridge is very energy efficient to use and use only 45 W per hour and it is classified as an A + fridge. The refrigerator runs on 230 And V can also be run on 12 V.
To cool down to the recommended temperature (4-5 gr.) cooling from 15 ° C to 0 ° C in only 15 minutes at temperatures of up to 43 ° C of outside temperature.
the statement 45 W per hour is not enough to comment on the refrigerator consumption. The refrigerator is connected to an hour it 45Wh (Watt timer), want it 24 timer (a day – max consumption) have spent 24 hours x 45W = 1080 Wh or 90 Ah – But a refrigerator running normally not all the time, consumption is the absolute maximum consumption. By using this refrigerator in the caravan battery, you should think carefully about which battery to choose, a solution where you select a battery with quick loading (f.eks Optima batteri) connected to a battery booster so happens charging while driving is clearly a good option.
