So this is Joe from BrewAllGrain.com and I've been following this forum. Our company has begun to manufacture the temperature controllers that you've been discussing but we have run into some manufacturing issues for full scale production as mentioned in my email above (thanks shroomsofdoom for the questions). We find ourselves at a bit of a turning point since fixing all these issues would put us down for awhile and have to change some aspects of the temperature controller (and add to costs).
When we've been developing this product, after multiple prototypes and going through multiple suppliers, we've been able to cut the cost of building one of these RIMS systems. One of the options we've been discussing instead of manufacturing the RIMS system is providing a step by step guide on how to build the system which would include where to buy each part for the lowest cost. Using all American suppliers and the local hardware store, this RIMS system could be made for under $125. Responding to TJCavitt's post, when you know how to build and where to get all the supplies it doesn't have to cost you hundreds of dollars to make a quality RIMS system. We're bouncing around the idea of selling this guide with all sourcing info for around $10.
As many of you have discussed, I would recommend not using the box enclosure if building at home due to leak concerns (we do numerous tests to make sure we have no leak points but if someone took it apart there could be an issue as you guys point out). The box is also the most difficult part to manufacture and is the only part of production that requires specialized tools. Everything else is straight forward to put together.
What do you guys think? Creating the guide would allow us to get rid of the headache that we’ve just found ourselves in manufacturing this system and building your own would allow for customization that a lot of our customers are looking for. Is $10 reasonable and would anyone be interested?
By the way, love the “That’s what she said” comment
