Where to get -150 non-LN2 Cryofreezers

Does anyone know if there is a company that makes upright cryofreezers (goes down to -140/-150) that do not use liquid nitrogen? All I can find are chest freezers that fit this description, but we have a space issue and really need an upright. Any suggestions would be amazing!

 Chances are it would be

 Chances are it would be difficult to create an upright that can reach -150. That s because you need to have flowing refrigerant move up to the top of the freezer, which puts more strain on the pump. Also, a chest keeps the cold air in when you open the lid, whereas an upright loses a lot of cold air when the door is opened.

Thanks Greg,

Thanks Greg,

It was sort of wishful thinking, I'm trying to get some equipment but have limited space. I appreciate your input!
