Besides freezers I don’t think there’s any technology we know that could do this on a wide range of substances. But freezers are neat - they move heat from the inside to the outside and as they are insulated they can reach temperatures 40-50 degrees (Celsius) under their surroundings

You can get “freezers” that will put part of their inside down to 250+c below their surroundings. (Helium cryocoolers)
This is cool! Where do I get one and what’s the power usage?
Semiconductor mfg firesales.
Or if you want to spend the 20+k you can buy from the manufacturer.
Oh power usage… that depends how much you need to cool down, and what setup you have. But usually they’re 3 phase and lots of amps…
