A price would help wouldn’t it... $1500. If not local to Houston or New Braunfels Texas, buyer would cover shipping.
I also have a bunch of components that I can give to the buyer that would help bring the cost down of building a controller.
Sorry, was posting multiple places and got carried...
Selling electric HERMS beer brewing system (control panel not included). Includes pumps, hoses and wort chiller in addition to the fully built kettles. Kettles are 30 gallon and I've used the system to brew anywhere from 7 gallon to 20 gallon batches. This is priced at just over half the cost of...
Hello, I've got a PLC controlled E-HERM's system for sale. To build the same system new would be over $9,500. I'm asking $5,000 or best reasonable offer. Will give preference to one buyer for all, but may be willing to sell the 'Other items' listed below separately.
I've only done four...
I run mine wide open and have not had a stuck mash. The HERMS coil and other fittings/hoses create enough back pressure that it's only flowing at about 2gpm using chugger pumps.
Rather than trying to go the route of a modulating valve for flow control, I'm going to get some of the variable speed pumps from ussolarpumps.com. From what I've found for valve options, the pumps will be a less expensive way to go...
A Johnson controller isn't going to flip on/off nearly as quickly or frequently. The frequent on/off shifting is where SSR's build up most of the heat.
+1 on this for two reasons. Turning the fan on/off that frequently will wear it out faster. Also, heat transfer isn't instant, so once the SSR switches off, it is still transferring heat to the heat sink. Having the fan on full time would be better to help dissipate all the heat.
You could...
Setting them up that way creates a little extra back pressure that will slow your flow rate some, but that's usually not an issue.
Edit: I was only referring to after the pump above. It shouldn't be enough restriction to hurt having it set up as a 90 before the pump, but I like the better...
