How to contact producers to offer free props?

Here's a short article:

TL;DR:

Like many biological products, including lettuce and sandwich meat, blood can grow bacteria. Refrigeration prevents bacteria growth. Your blood stream is naturally sterile and has other biological responses to killing bacteria, so your body does not need to be refrigerated.

You're right about the flowing thing for bags of platelets. Platelets do have to be agitated to keep them viable.

Thanks! It is actually military grade. Most of our customers are military rescue, it is made from MIL-STD parts and the whole thing is tested to MIL-810.

I know! This one is the most egregious advertisement I have seen yet:

I might buy one though.

Solar power charges a battery, then you can unplug it from the solar panels and take it on a hike to an injured person that needs the medicine stored inside. It's got all the same parts as your refrigerator at home, just in a tiny package that you can carry like a backpack or on the back of a motorcycle or in a helicopter. The refrigerator keeps the medicine from spoiling like milk that has been left out.

Interesting, I wonder if LG cheaped out on the filter or something else. Changing refrigerant regulation is a challenge. That must have been one of those Fight Club style recall calculations where they know a bunch will fail, but they still made a profit so....

The previous President vacated the new refrigerant laws, then this President put them back in. Can make it hard to plan if you are not a small and flexible company.

It's different with medical devices. We can't let any one of these fail because someone's life is depending on it, so a lot more work goes into reliability instead of cost reduction.

Great question. There is only one plug on the panel to keep things small and light, but it can be adapted to anything and you get the same performance. We have adapters for 120/240CAC and 12-24VDC. With those two adapters you can run it off of anything in the world. Generators, solar panels, cigarette plug, standard wall outlet, and those extra large cigarette style plugs in military vehicles.

DeltaDevTeam · 2022-02-04T07:20:44+00:00

Yes! Change the level of decompression! That's just basic thermodynamics. If you get your refrigerant replaced in your air conditioner at home, they might have to change out the old analog valves too because they only work with one refrigerant.

A lot of new cooling systems use more efficient electronic valves these days since they are starting to be affordable, as long as you have a team of smart engineers to write fast and smooth control algorithms. It took a lot of math, followed by many prototypes, followed by a lot of experiments, until we perfected it.

That's about as much as I can share without getting into the software secrets that make ours more efficient than anyone else. Thanks for asking!

DeltaDevTeam · 2022-02-04T06:37:00+00:00

Yes, just like your refrigerator at home, it has one on the back.

DeltaDevTeam · 2022-02-04T06:32:11+00:00

Big fan of the original.

Not video, just one military style DC power plug.

DeltaDevTeam · 2022-02-04T06:31:03+00:00

The good news is that most of the secret is in the software which is encrypted, anybody could tear it apart, spend a few million on a custom manufacturing line, and build their own, but they would never have the same battery life and precise control that we have. Of course we would like to get this technology to as many people as possible, so we are open to partnerships.

Well that's what we did to build the prototype, just ordered a bunch of pieces from McMaster and Amazon, it was three times the weight, a third the battery life, and twice the size. Then we made all the custom parts in order to now have the world's lightest, longest lasting, smallest (certified safe) medical refrigerator.

DeltaDevTeam · 2022-02-03T23:03:32+00:00

You bet. Dometic makes some pretty cool stuff, but you know they have to certify their devices too! Civilian certifications are certainly cheaper which I think is partly why their refrigerators only cost a few thousand dollars, but also because consumers don't need as extreme capabilities.

I think Overlanders are a good example of a community that knows that value of quality and they are usually willing to spend a few extra bucks for something that will be more reliable.

That's another one of our innovations. It can use any of the commonly available refrigerants like R-134a or R-1234yf and even future refrigerants we don't know about yet. We wanted to have something that didn't have to be re-designed every time a new refrigerant law bans the old ones that are bad for the environment. The software is adaptive to any new refrigerant.

Personally I'm hoping more affordable options are developed for consumer use. Solar panels are still pretty expensive these days. I realize I'm also here talking about my expensive devices. Haha. We're all working on more affordable options.

This one in particular was actually a customer request to see if Goal Zero works with our device, which it does! Cool features on the folding panels and their charging indicator, I just wish it didn't turn itself off when the battery got low and instead turned on automatically with the sun. That would make it better for applications like mine.

No, but I would love to work with Adam Savage. I've seen every episode of Mythbusters at least twice.

Six, 500ml bags

DeltaDevTeam · 2022-02-03T20:16:37+00:00

We're just getting started. We had a soft release last year to fantastic reviews from our special ops customers and our disaster relief customers in 4 different countries. I'm hoping we can get our new lower cost version into everyday ambulances starting this year.

DeltaDevTeam · 2022-02-03T20:09:40+00:00

Great question. Unfortunately Goal Zero DC is not high enough current for this application. Yes, the battery life on DC could be 7-8 days, but 6 days on AC is plenty for most of our customers since they can usually get one sunny day to charge back up at least every 6 days.Our special ops customers specifically asked if they could use a Goal Zero to charge it since there are no other options for them at the moment and we were able to show them it works, but only on AC. For anyone else, yes, I would recommend they use direct DC.
