How full can I fill a recovery tank?
To prevent overfilling, recovery cylinders should not be filled to more than 80 percent of their internal volume. Most technicians accomplish this by placing the recovery cylinders on an electronic scale and monitoring the weight of the cylinder during the recovery process.
How much can a 50 lb recovery tank hold?
For example, a 30 lb cylinder can hold 22 lbs of refrigerant and a 50 lb cylinder can hold 38 lbs of refrigerant. 2.
How much does a recovery tank hold?
NEVER Exceed Refrigerant Recovery Tank Limits By law, a tank can only be filled to 80% capacity and must be kept under 122°F. It is recommended to fill to 2 lbs less than the 80%.
What happens if you overfill a recovery tank?
Overfilled storage containers may explode due to liquid refrigerant expanding when heated. Transportation of refrigerant stor- age cylinders more than 80% full is a DOT violation.
How much does a 30 lb recovery tank weigh?
Table 3: Acceptable cylinders
| Cylinder size | Max pressure | Typical empty weight |
|---|---|---|
| 30 lb. | 350 psig | 14 lbs. |
| 400 psig | 17 lbs. | |
| 50 lb. | 350 psig | 24 lbs. |
| 400 psig | 28 lbs. |
Can you mix refrigerant in a recovery tank?
In the case of the first category — intentional mixing — an obvious suggestion is to avoid mixing different types of refrigerant in the same recovery cylinder. Unintentional mixing can certainly occur when systems or previously filled recovery cylinders are not labeled correctly.
How long is a recovery tank good for?
By law, refrigerant recovery cylinders must be tested and recertified every five years.
How much does a empty 30 lb Freon tank weigh?
it should be stamped on it as tare weight (TW). Typically it is 4 to 7lbs.
How much weight can you put in a recovery tank?
You get 22.95 lbs to fill the tank completely. However, you cannot completely fill the tank. You must only fill it to 80%, so you multiply the 100% full weight (22.95 lbs) by 0.80, which gives you 18.36 lbs—rounded down to 18 lbs—of total internal R410a weight (I go down to 17 just to be extra conservative).
How big can a refrigerant recovery tank be?
All tare weights and dimensions are approximate. To convert to refrigerant capacity: Maximum allowable gross cylinder fill weight is 0.8 x water capacity x specific gravity of the refrigerant recovered @ 77°/25°C + cylinder tare weight. REC-TANK-50 REC-TANK-30
How much does a coolant recovery tank cost?
With parts markup and a labor rate of $100/hr, coolant recovery tank cost should run about $200. Alldatadiy.com and Eautorepair.net are professional-grade shop manuals—period.
What’s the boiling point of a recovery tank?
In those applications a recovery style tank may be used instead. Liquid cooled systems are pressurized in order to raise the boiling point of the coolant. The boiling point of a 50/50 coolant water mix is 226 degrees F at 0 psi. At 16 psi the boiling point of a 50/50 mix is 267 degrees F.
