    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)

          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…
