How long is a recovery tank good for?
Per DOT regulations, recovery cylinder certification expires five years from the date of manufacture. By the five-year mark, the recovery cylinder must be certified by a facility approved by DOT. When a cylinder is recertified, the recertification date is marked on the cylinder in one of two ways.
What is the max pressure for a recovery tank?
400psi
The max working pressure of the recovery tanks must be over 400psi. 7. Do not overfill the recovery tank. Tank is full at 80% volume.
What is a refrigerant recovery tank?
These DOT-certified recovery cylinders can be used to safely recover, store and transport used refrigerant from HVAC and refrigeration systems to EPA-certified reclamation centers, where the gas can be cleaned and recycled or properly disposed. Do not vent cylinders into the atmosphere.
How do I know what size recovery tank I need?
The water capacity of a recovery cylinder normally is stamped on the outside of the cylinder. For example, if a recovery cylinder has a water capacity of 47.17 pounds, then its internal volume will be 0.75 cubic feet (47.17 pounds ÷ 62.5 pounds/cubic foot = 0.75 cubic feet).
How much does an empty refrigerant 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.
What should a technician do if the refrigerant in a recovery cylinder is contaminated?
What should a technician do if the refrigerant in a recovery cylinder is suspected to be contaminated? Turn refrigerant in for reclamation. Before beginning a refrigerant recovery procedure, it is ALWAYS necessary to; Know the type of refrigerant that is in the system.
Is your refrigerant recovery and recycling equipment meeting EPA requirements?
EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act require that refrigerant recovery and recycling equipment be tested to ensure it meets EPA requirements.
Can I use my recovery machine on a different refrigerant type?
Just because your recovery machine has an oil-less compressor with a pump-out feature, does not mean you do not have to change the drier and pull a vacuum on the recovery machine before using it on a different refrigerant type. Proper safety and training, although required by Section 608 of the Clean Air Act, is only part of compliance.
What should I look for when inspecting a recovery cylinder?
Weigh cylinders on an accurate scale, and inspect them before filling. Look for dents and rust, and check the DOT certification date. If the cylinder has rust, dents, or the certification date is overdue, do not use the cylinder. Recovery cylinders and drums must be painted gray with the shoulder portion painted yellow, per DOT regulations.
What are the requirements for small appliance recovery equipment?
Small appliance recovery equipment must be able to recover either: 90 percent of the refrigerant in the small appliance when the small appliance compressor is functional, or. 80 percent of the refrigerant in the small appliance when the compressor is not functional.
