Ultra low watt density heater for RIMS system

[Ramdough]

Does anyone have a recommendation for an Ultra low watt density heater for RIMS system that is strait (not wavy like Kal's e-brewery)? I would like the same or less watt density as Kal and strait to fit better in a tube.


Thanks

yup I seen them recently there too

Do you know if they have the same watt density?


That is what I am looking for.

um they are "ultra low watt density" which is less likely to scortch the wort... because they likely aren't as long as the wavy ones they will not have the same surface area to the wort... Unless to found a really long one.

No they don't, the watt density is higher than the CAMCO 02963.

Has anyone ever found one that is longer with equal or lower watt density?

You do realize that even a 4500w element is overkill in a rims tube application? I would think any 5500w uldw element would do what your looking for? are you trying to bring it from tap temps to boiling in one pass or something?
I'm building one now with a 1000w stainless element.

Check out this site: Boston Heating Supply - element link

I think you will find what you need there.

Bobby M gave me this tip when I picked up my Rims Tube from him. Lowes has a store brand 5500W element that if you run on 120V will operate @ 1375W

Surprised this question hasn't come up yet. Are you running 120 or 240? I've got a 5500 ULWD from amazon that will be run at 120 which will spread the wattage out even more. It's about 11" long and straight.

 

[augiedoggy]

I assumed it was being ran at 220v since no mention of running it at half power came up. plus he was specifically looking for 5500w...

 

[Ramdough]

I plan on using an arduino with multiple RTD temperature sensors and then driving this element with a digital dimmer circuit, so the wattage used will change based on a desired change in temperature.

In reality, the voltage will be probably low generally because I will start with water that is at temperature from the HLT. It will only be used to maintain temperature.

I wanted the low watt density just to make it less likely to collect junk on it.

Thanks everyone for your feedback.

Think of how long it would need to be. Why would a manufacturer make a water heater element too long to fit in a water heater? Use a high wattage 240v element folded onto itself and run it@ 120 v. It's an easy way too make an uld out of a low density.

Or. you could go onto amazon and buy a ULWD (Camco) that is barely over eight inches long that fits in my RIMS tube great and you can run it at the specified voltage.

 

[cjgenever]

Yes, agreed. Looks like that has about 28-30 inches of element. The 220v option is a bit longer giving even lower heat density. Either would work just as well with 120vac. I suppose the decision here would come down to size requirements.

I don't recommend it. Amazon has been representing the Camco 2853 as ULWD at just under 8" for a really long time http://www.amazon.com/dp/B000KKVZUO/?tag=skimlinks_replacement-20

and in reality it only measures 4" and the fold back section is only 1". That means it's about the same density as a 5-6" straight element.

If you're happy with 1500 watts, the best way to achieve it is to put the largest 5500 watt 240v element in there that you can fit and run it on 120v for 1375 watts.

Running an element at its rated voltage is fine, but it's not like running it half voltage carries any liability with it. These things are big resistors.

I bought this exact supposed 8" element from Amazon and return it. It's ridiculously short (4" is a close measurement) and in reality would have had very contact with the wort on the in port side of the tube because of it's length. I got this element and it's almost 11" with a fold back portion of about 5" or so. It's perfect for a RIMS tube. Step mashing would be annoying, but I don't do that. Mash out might be a 15 minute process, but that's not bad when you can get full conversion in 45 minutes with a RIMS set up.

 

[cjgenever]

The camco 5500w (1375w @120v) lwd I use is in stock@ hd and is probably about 9" long. There is also an uld in stock at like 11 or 12". My 240v element is uld 5500w ripple@about 15" long (bk)

I use the Camco 02933 @ 120v for 1375w and it works fine and keeps it within range for a 15 amp circuit.

 

[cjgenever]

Yeah, @1375w I can run a cord to an outlet in the kitchen and still be able to use countertop appliances. My house is all 12 ga so my breakers are 20a. The gfci's are 20a as well. Don't know why the electrician did that... I would have used cheaper 15a gfci w/ 15a breaker. He still would have needed 12 ga due to voltage drop. Whatever, it helps me

I don't worry about sharing grounds since it is only temporary and every circuit does have its own appropriately sized ground. There is no fire hazard that way.

if its a dedicated line and its 12ga the 20a breakers and gfci are a benefit especially when it comes to kitchen outlets were the 20a is utilized by appliances like coffe makers and toasters..microwaves. you can run two of them on the same circuit with a 20a line with no worries.... The 12gauge wire is the only real cost increase as far as I understand it. I'm not sure what you mean by "voltage drop" though? is it a long cable run?

The cost of 20A gfci outlets is quite higher that 15A. It's also not required, so I too find it odd his house is all 20A gfci outlets. Score!

They are required with the 20a breaker.

It's not dedicated. It simply feeds the entire kitchen

Only if your circuit has a single outlet. I'm sure those exist, but personally I've never seen that. Most have 2 or more outlets on the same circuit, which is perfectly legal to run 15A.

 

[atoughram]

This is the 2KW 240V element I use in my RIMS - three brews and works well.

I see... since you only have one breaker for the whole kitchen it makes that much more sense to go with a 20a breaker....
So what He did makes really just makes sense to make it possible to run 20a appliances....
