What does a Section 608 certification allow a technician to do?

Section 608 technician certification is required to dispose of appliances, except for small appliances (an appliance that is fully manufactured, charged, and hermetically sealed in a factory with five pounds or less of refrigerant), motor vehicle air conditioners (MVACs), or MVAC-like appliances.

Which transport modes does EPA allow technicians to be Section 609 certified?

Any person who repairs or services a motor vehicle air conditioning (MVAC) system for consideration (payment or bartering) must be properly trained and certified under section 609 of the Clean Air Act by an EPA-approved program. All technicians servicing MVAC-like appliances must be certified.

Does EPA certification expire?

EPA regulations (40 CFR Part 82, Subpart F) under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified. Section 608 Technician Certification credentials do not expire.

Is refrigerant certification needed and what can happen if I don’t have it?

Any person servicing, installing or disposing of stationary appliances (except the disposal of small appliances) must be a section 608 certified technician. Selling refrigerant to an individual or company that is not complying with this requirement could result in enforcement action against you or your company.

Do you need a license to buy R22 freon?

R22 refrigerant is illegal to import and manufacturer in the U.S. But it’s not illegal for anyone to buy R22 freon. And it’s not illegal to sell it IF you have a license. As long as the stocks last, you will be able to continue purchasing R22 from specialized dealers and form your air conditioning company.

Do I need a license to buy 410a Freon?

ANYONE can purchase and handle 410a. NO certification or license needed. Therefore, section 608 technician certification is not required in order to purchase HFC refrigerant substitutes that do not contain an ozone-depleting substance.

What is suction and discharge pressure of R410A?

What is the suction pressure of r410a? Suction pressure of an Air-Conditioner with R410A Refrigerants typically ranges between 115 Psig to 125 Psig when operated at an ambient temperature of 35 degC. The discharge pressure at this operating conditions hovers around 400 Psig.

How much does 410A refrigerant cost?

The typical cost of R-410A freon is $125 per 25-pound cylinder, which equals out to be $5.00 per pound. The average home uses two to four pounds of R-410A per ton of your air conditioning unit.

What refrigerant will replace 410A?


Is 410A going to be phased out?

All new home AC units in North America uses R410a, also known as Puron. But this refrigerant will consequently be phased out. This is due to a continued focus on reducing compounds known to have an effect on the environment. But it’s not so much the air conditioning system itself, or even its cooling performance.

Does 410A cool as well as R22?

The lower critical temperature of R410A versus that of R22 (70.1 °C (158.1 °F) vs. The R22 system cooling capacity decreased by 14 % at an outdoor temperature of 51.7 °C (125.0 °F). The R410A system cooling capacity decreased nonlinearly by 22 % at the same condition.

Why is R410a so expensive?

Unfortunately for homeowners, the price of R410a has increased significantly over the past few months. There are two major reasons why this has happened. The first reason is a simple matter of supply and demand. As R22 is phased out, the demand for R410a increases, and producers haven’t been able to keep up.

Is R410A harmful to breathe?

EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate. INHALATION: R-410A is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur.

Is R410A more expensive than R22?

“The cost of R-22 is somewhere between $75 to $100 a pound, where the cost of R410A, which is the replacement that we use, is $30 a pound,” said Dan Brizee, the president of Brizee heating.

How much does an empty R410A cylinder weight?

9 pounds

How much r22 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 an empty recovery tank weigh?

Determine the tare weight of the recovery cylinder, which is the weight of the cylinder if it were empty. This is also stamped on the outside of the cylinder. For example, for a nominal 50-pound recovery cylinder, the tare weight would be 24 pounds.

How much refrigerant does a recovery tank need?

So, How much refrigerant can a recovery tank hold? It’s 80% of whatever size recovery drum you are using. Depending on the size of the tank it’s different, obviously. Each tank is stamped with a tare weight, just the weight of the tank empty.

How much refrigerant can you put into a 50 lb recovery tank?

Table 1: Recovery cylinder information

Cylinder Name Water Capacity Allowable Refrigerants(2)
30 lb 26.2 lb 726 in3 All(1)
50 lb 47.7 lb 1323 in3 All(1) except R-410A
125 lb 123 lb 3406 in3 All(1) except R-410A

How do I calculate my refrigerant recovery tank capacity?

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. JB refrigerant recovery tanks are trusted by HVAC recovery professionals for safely storing or transporting refrigerant.

How do I know if my recovery tank is full?

Tare weight is simply the empty weight of the tank and must be factored for whenever you are weighing the total weight of the tank. Next look for a stamp that says WC, this indicates the water capacity of the tank, the total weight in liquid water to fill the tank 100%.

How much does an empty refrigerant jug weigh?

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….What if I can’t find the tare weight on the tank?
