There is a risk that both your propane tank and your propane regulator will freeze during the winter. Frozen tanks will prevent propane from being delivered when needed. The good news is that there are tricks that can be used to prevent this from happening.
Have The Right Propane Volume
The propane tank will freeze when the ambient temperature falls below -44 degrees Fahrenheit. Because off this problem, the tank is less likely to freeze if it has a full volume of propane. However, make sure to not overfill the tank because the propane that splashes out is not only a waste, but can also freeze the regulator. The good news is that there are overfill prevention devices that can be installed on your tank in order to prevent this.
Know The Pressure Rate
Know the pressure rate of your tank. If you pull more pressure than what your tank was allowed to provide, or if you pull a large amount of pressure for a period of time shorter than what the tank was designed for, this can increase the risk that your tank will freeze.
Keep The Tank Properly Positioned
Make sure that your propane tank is elevated. This ensures that liquid does not leak out of the regulator and that the liquid does not freeze. Also, make sure that the tank is positioned according to the manufacturer's instructions. If it is not positioned correctly, the liquid propane can back up into the regulator, freezing it.
Keep The Tank Warm
Purchase a propane regulator cover. This is a cloth that will keep the regulator warm. In very extreme cases where the tank will be subjected to very low temperatures, wrap the tanks in electrically heated blankets.
Use The Right Additives
Additives can be used to reduce the chances that your propane tank will freeze. When hydrocarbon chains break down, this can lead to a gummy residue forming that can lead to water deposits that can cause the propane tank to freeze and can also foul the fuel. Fortunately, an additive known as LPG can prevent this from happening. The fuel should also be injected with methyl alcohol additive because this will also make it less likely that the fuel will freeze.
Properly Position The Regulator Drain
The regulator comes with a vent hole. Make sure that this is positioned so that the excess propane will drain. Otherwise, the propane fluid will build up over time and will freeze the regulator. Fortunately, these tricks are simple and will ensure that you always have access to your propane.
