Wow, what a great forum! Seems like two guys run the thing. Forums like this are to supposed to share and present information, not bash it. Someone at the top of the thread had interest, so we simply presented it as an option.
Nothing intended to discredit anyone or any product, just information.
If you understand about UL with packaging a piece of equipment with CO2, you understand costs. You can't compare this to a dive bottle or anything else, as UL treats this differently. We also understand production, as being a manufacturer for over 25 years now, so not that easy to just give away units. Over a short time as the other markets have shown with more competition, the price will go down quite a bit.
I know your US manufacturer quite well and they are a good company. Have purchased a lot of product from them as a matter of fact, but thanks for the bash on our intelligence.
These units are not hiding either, over 300 sold in one year and made in a high quality ISO 9001 facility with the best manufacturing equipment available.
Last, it was not said that CO2 was a wonder refrigerant, quite the contrary. It needs to be applied a certain way, or it really offers no benefit, other than one MAJOR fact. Look at it's GWP and ODP and compare it to what you are using, other than ammonia of course which in our opinion is probably the best. Of course the topic of GW is a hot bed with some believing it and others not.
Sorry for offending anyone here, that was not the intention at all.
