Where to purchase individually wired rack? (IE: each shelve has it's own plug)

[Eric Alan]

Seeking 4/5 level 32qt shoebox rack that has each shelve wired individually.

The companies I have spoken to so far only offer racks that utilize one long strip of heat tape for all levels.

Any insight is greatly appreciated

I'm just curious - what's the plan? What's your need for separate wiring? I assume for separate thermostats, but what's the logic behind this? Just curious and always looking to learn something new!
