I’m looking for a Peltier cooling module and controller for my 3D printer.
I have not used Peltier devices before, So I need help choosing a proper module for my application.
Room temperature : 20 - 34 Degree Celsius
Peltier cooling: Below -10 Degree Celsius
Application: Cooling down a syringe containing liquid
I also have some doubts
Q1. Can the same module be used to heat the surface if I reverse the polarity of supply( I want the same end to be cold sometimes and Hot some other times)
