Ship a freezer by air?

Is it possible to ship a consumer freezer (such as this one: https://www.danby.com/products/freezers/dcf072a2wp/ ) by air? Or will the refrigerant gas expand too much and break the freezer?

What are the risks?

I am not talking about the safety considerations/dangers to the crew (I know it is classified as a "dangerous goods": UN3358) but even if it is allowed on board an aircraft, is it a good idea? or will the freezer be damaged by air travel?

Thank you!

We ship aircons and freezers/fridges all the time. Never heard of problems.

Considering the pressures they are operating under normal operation, the extra bit from cabin alt is hardly likely to damage it.

Talking from the top of my head, as I don't have access to the ICAO DG manual, but freezers normally have little enough refrigerant not to need a DG consignment. 12g limit, IIRC

Why would you do that? I can understand that occasionally freezer and fridges need to go places quickly but usually it should be perfectly acceptable to ship them by ship. "All the time" seems a bit more frequent than I would expect.

I remember seeing F-1 cars and race horses but never a freezer! LOL

Thanks for your reply! I was thinking about bags of chips that can't handle air travel...

Are you sure the 12kg UN3358 exemption applies to air travel. I thought it only applied to ground shipments?

An air cargo freight forwarder should be able to tell you if they can they can accept a commercial freezer as air freight or not. You'll just get internet opinion here - worth about how much you paid for it..

But googling netted this.

https://www.hazmattool.com/info.php?lan ... 3358&c=2.1

and returned forbidden in cargo and passenger aircraft but like anything there are always exceptions, and maybe 173.306/307 contains an exception you might be able to use. 307 mentions a 12kg limit

the freight forwarder that you pay can tell you for sure..

Yes, UN3358, but the question is if the 12kg exemption only applies to ground cargo or also to air cargo? I get conflicting information at the moment. Still making research.

But my question was: Even if it is allowed, is it a good idea? Considering that even a bag of chips cannot withstand air travel.

This 12kg exemption seems to be only for Ground shipments. I don't know if there's another exemption for air though. Someone at FedEx told me about a 100g exemption, then another said that, no, freezers don't ship at all by air. I think no one really knows at FedEx. Maybe @SAAFNAV could enlighten us.

There are a number of specialised ULDs for temperature dependent cargo which essentially have a battery operated refrigerator, they are carried on both cargo and passenger aircraft under floor.

It really depends on what the refrigerant gas inside the unit has, R410a, R134a, R404a (2.2 Non- Flammable Gas), under IATA air special provision 26, units containing less than 12kg of non-flammable refrigerant gas could travel by air. Newer equipment may have R32 refrigerant, those with containing 100 grams or more of R32 refrigerant are forbidden to travel by air, as R32 is flammable, and machine containing this have to be tested to higher pressures.

Regardless a freezer would need to be packed and documented by a licenced freight forwarder that would be aware of these IATA provisions.

The freezer mentioned in the OP has R600a refrigerant gas inside (from https://www.danby.com/products/freezers ... 2wp/?o=pdf ), which is UN1969, normally forbidden on passenger and cargo aircraft.

Living in rural Alaska and not on the road system, I have pretty much everything delivered by airplane - including refrigerators and chest freezers.

Sometimes they get put on their side during shipping and out of a precaution you'll want to leave it sit upright for 24 hours before turning it on.

Unfortunately I can't help now, as we're grounded and we only have the hard copy of the IATA DGR.
All I know is that I have personally loaded refrigerants before, and looked up the codes before accepting the cargo.

I'll ask a friend who's out on station if he can look up the regs, then I'll share it. Can't promise when and if the info would come through.

I have a few -80C Freezers in my lab that I bought in USA and they were shipped to GRU from IAD or MIA in both UA or AA. Pretty common.

I don't see how density altitude would be a major issue, given that they have freezers in places like ABQ.

Projects I have been involved with in Guam have shipped 10 Ton capacity AC units by air to there. As all the refrigerant is within CU tubing and has operating pressures around 30 PSI on the low side, and over 200 PSI on the high side there is no issues with pressure shipping on an airplane. When recharging, the suction side is drawn down to a full vacuum. As to hasmat and flammability I will defer to others.

Just think of how many freezers are being used at an altitude higher than the cabin altitude.Millions probably.

It is possible yet you can save money by moving a fridge yourself. You can disconnect your fridge according to the user manual. I experience shipping a fridge before and there was no problems encountered. You can ask a friend of yours to help you with the shipping or look for a freight forwarder. They for sure know what to do.
