Produce farmers often ask this question for vegetables that like to be very cold and some more delicate vegetables that will get damaged at very cold temperatures.
It is possible to use 1 CoolBot and 1 A/C to have two different temperature zones in a cooler, but we don't recommend the setup. The main issues are twofold:
- Temperatures want to equalize so you won't have much of a temperature difference between the two sides over some time (e.g. overnight)
- It is difficult to get the partition set up correctly. Plastic cooler flaps are not very efficient, and you can only expect a few degrees of temperature differential. It's better to build a wall with a door and work at adjusting a crack under the door by about 1/4" at a time to try to get the temperature you want in both sides of the cooler
Given the issues discussed above, we recommend 2 separate air conditioners and 2 CoolBots for this type of setup. That way there is no guess-work around the partition set up and you can adjust the temperatures in the two coolers as needed.
