Refrigerant comes in all sorts of containers from small cans to 145 lb cylinders! When going through those old containers in your garage, or shop, the best way to figure out how much refrigerant is left in your tank is to weigh them. Weighing them can be done with either a bathroom scale or a refrigerant scale, if you have one, and then you’re good to calculate!
Whatever weight the scale reads is the gross weight of your material, which is the combined weight of the container and the material inside the container. This doesn’t tell us how much refrigerant is left and this is where tare weights (TW) come in handy! The tare weight is how much the tank weighs empty. When the tare weight is subtracted from the gross weight you are left with the net weight of refrigerant.
Pounds of Refrigerant Inside Tank (Net Weight) = Gross Weight – Tare Weight
How do you figure out the tare weight for a refrigerant tank?
After years of experiences and thousands of tanks processed, we have calculated exactly how much these tanks weigh when empty. Below are the tare weights of some of the most common disposable refrigerant containers we come across. These tare weights can vary depending on the manufacturer.
What about 145lb cylinders and recovery tanks?
The tare weights for these kinds of containers can usually be found etched into the tank itself. Below are some examples of where you can find these tare weights etched. Note that this can vary from tank to tank.
What if I can’t find the tare weight on the tank?
Here are some tare weight estimates you can use:
|Cylinder Type||Tare Weight|
|30lb recovery tank||18 lbs|
|50lb recovery tank||28 lbs|
|145lb cylinder||52 lbs|
|100lb drum||14 lbs|
|200lb drum||20 lbs|
