What causes this to freeze? I have not had this problem before and the regulator does not have that many hours on it. The tank is a 6. The temp here is low 40's. Should I turn down the propane output? Its a 3ht LG.
I do not want the brass to freeze and crack spewing out propane which get ignited by the heater and then a big boom.

Freezing Regulators - Frost on LP Gas Regulator During normal operation propane regulators can become covered in frost, which may alarm some users.
While this "freezing" of the regulator may be a symptom of an actual problem, it usually is a sign that outside humidity is at a level capable of producing condensation. The only difference is, the condensation forming on a regulator is frozen. Once a propane appliance is actively in use, the liquid propane in a tank or cylinder begins to boil.
The propane vapor, as boiled off the top of the liquid begins its journey downstream to the point at which it is used. Before making its way to the LP Gas system piping, it passes through the regulator where its pressure is reduced to a usable level. Keep in mind that the regulator will only deliver a constant pressure on the outlet side while inlet pressures can significantly vary.
As the propane passes through the regulator, it expands resulting in sub zero temperatures and causes the regulator to gradually reach the extremely cold temperature of the propane vapor passing through it. Depending on the temperature and humidity of the surrounding air, the regulator will produce condensation, much like that of a frozen mug or glass taken out of a freezer.
This is why, under normal operation in hot and humid climates, the external surface of a regulator will freeze and appear to be frozen or frosted. The rate at which propane is being withdrawn from the tank or cylinder will also cause the container to display a visible frost line, which indicates the liquid level of the propane within the tank.
Maybe I should of googled first. Can the brass crack and cause a leak? No it won't crack but it can freeze bad enough to blow off propane through the vent. Is your regulator inside the truck near the heater? KevinD said:. Click to expand Leslie Judson Jones Member. Propane cylinders containing OPD valves have the design to prevent this problem. However, cylinders and tanks without OPD valves can be completely full with liquid propane and result in liquid flowing through the service valve, into the regulator and downstream to appliances that work with vapor.
Again, while this is not common and not probable, it is possible. Your email address will not be published. Leave this field empty.

The industry norm is 15 years before a regulator needs replacement while some regulator manufacturers recommend replacement every 25 years. If any regulator has ever been under water, such as on an underground propane tank, it needs to be replaced immediately.
Does cold weather affect propane regulators? Cold outside temperatures not only freeze lakes, streams and fingers, they affect propane tanks. The storage container uses pressure to keep propane in a liquid form. Propane appliances might not function correctly if the outside temperature surrounding a propane tank becomes too cold. How do I keep my regulator from freezing?
The problem of regulators freezing can be eliminated by using only dry fuel and keeping the fuel free of water until it passes through the regulator. Is it dangerous when a propane tank freezes? Propane tanks can freeze up while in use. Usually it is a sign the regulator is feeding the propane too quickly, or there is a high level of humidity.
It may be alarming to notice the tank is freezing up, but it is not dangerous. However, it can leave you without propane until the tank is unfrozen. What is a two stage propane regulator? Second stage regulators work with propane at a pressure supplied by the first stage regulator inlet pressure and further decrease that to a pressure that can be used by appliances outlet pressure.
Most outlet pressures of second stage regulators are measured in inches water column, such as 11" water column. What happens when co2 is compressed? When Carbon dioxide gas is compressed at room temperature and the pressure is suddenly released, then it solidifies to form dry ice which is also known as solid carbon dioxide. It directly converts from solid state to gaseous state without melting to liquid state.
