Overview

Our TC-100 temp control system will manage both cooling and heating of your Flex. The digital controller's temperature probe inserts into the included thermowell that attaches to the secondary port of the Flex. Also included is a specially built neoprene jacket with reinforced port holes to ensure a perfect fit. Lastly, (and the coolest item) is our special insulated tubing. This reduces tube cooling losses and will prevent your cooling lines from sweating all over your floor during the dog days of Summer!

Cooling: When the temperature in the Flex rises above the set point of the controller, it will turn on the pump submerged in your cold-water reservoir (bucket of ice water, aquarium, glycol chiller, DIY AC chiller, etc). This will pump cold water/glycol through the temp control coil, which mounts to the lid, cooling your beer until it reaches the controller set point.

Heating: When the temperature in the Flex falls below the controller set point the optional heater will kick on warming the unit up to the desired temperature.

Great bundle to keep fermentation at desired temperature

Fermentation stays within 1 degree of desired temp. I recommend using ice packs in the bucket with cooling water to ensure it stays colder than desired fermentation temp. Waiting for the winter months to try out the heater.

Works very well

I am wrapping up my first fermentation with the TC-100. Basement at about 60 degrees ambient temperature. Kept my lager right at 54 F during primary. Jacked it up to 66 for diacetyl rest. it performed exactly as I expected. I used a bucket of water in a keezer as my cold water source. I think when I go to cold crash, I may need to throw in a fair bit of ice to keep the water cold enough. So, that's a bit of a bummer but, not the fault of the TC-100. Previously, I did a test with just water. I was able to get 5.5 gallons of water up to 89 degrees F with the heating pad. At that time, ambient temp was more like 57F. But, with the heat made by a kviek fermentation that should be good enough. Not sure - but it seems like with the jacket on, I have a harder time getting a signal from my Tilt. Note - I have the pressure manifold on there because I was getting no airlock action despite active fermentation. The Flex+ held pressure with the manifold on. Therefore, I know it was my **** not sealing properly - as I suspected. It's very nicely made. My only potential beef with it is the temperature probe. It just kinda sits in the thermowell. I wish it was held in there a better. I'm using a piece of blue tape to keep it in there. Not a big deal. Just a bit of a bummer.

Very much worth the price

We now have the TC100 for all four CF15's and our Flex+. We began using ice in a cooler which worked well for fermenting the bottom fermenting yeasts. Once we upgraded to a glycol chiller, these things really impressed. Using the Inkbird temp controller (rebranded by Spike) we can set the high and low temps maintaining optimal fermentation temps regardless of the ambient (basement) temps. I will never buy another fermenter with getting the temp control package.
