Peltier are ungodly ineffective..... Interesting thought tho

Sent from my SM-G973U using Tapatalk
I believe these use peltier chips to cool beer to 35 or so below ambient, and a good amount of people use them from what I hear, but I don't have the cash for them...

I think maybe you meant in-efficient and you'd be right for sure but I was thinking if you had surplus solar its not getting used anyway and you could pre cool the insulated keg then use the ARB for final temp drop.

I use a peltier cooler in my service truck and it gets pretty damn cold, not freezing or anything but it will easily keep my drinks cold. They are not the best for allot of projects but they are simple.

That's a good price on that pump. I have been wanting to add a bladder tank to dampen the noise and provide short burst water supply without running the pump (night time piss break).

Sorry yes, inefficient. I do have excess solar on days in direct sun for sure.

I too have looked at the accumulator tanks. May not need one now, I cant hear the pump anymore. Like the water splashing is louder with the bench assembled.

That's what I am after. With my pump (looks like your old pump) the pex rattles to the shower so loud it sounds like the pump is diesel powered.
I figured the bladder tank would lessen the demand on the pump and help quiet it down.

Yeah mine was the same. I was told longer flex sections would help as well, but this is a world of difference.

Not sure if you've had much experience with mobile beer/jockey boxes, but I can never get it to the point of non-foaming. I hear you should run like 30psi to keep the gas in solution but I dunno...it never works out for me... I have 2 jockey boxes (25' and a 50' 3/16 SS coil in a cooler of ice), and keeping the keg as cool as possible is your best bet. I hear cold plates like yours can be even tougher to manage. Let me know how it works out!
I have a jockey box that has something like 100' of 5/16" and then drops to 30' of 1/4" or 3/16" just before the tap. It works crazy good. Taken it to parties, camping, the parking lot of the bar, all kinds of places and it's always cold and non-foamy. I run it at 30psi. It is a beermeister brand that's in a screwtop 10 gal water cooler. Had lots of good times with that thing, I think I bought it in '95.

Yeah I wanted to be able to use the fridge too, IIRC they said this plate was equivalent to 44' of line. Im getting a fair bit of foam...... Running 15psi

Misadventures in upholstery.... Oy. Not my forte.

Cut and pack in a bunch more insulation



definitely the correct stapler?


What am I doing?!


Spray glue?


Getting somewhere.....


Now the hard part..... Cant be tight as the truck moves, looks worse in the pics....More staples.
Those ribs on the back wall didnt help at all with no stretch fabric....


Switch panel and power by the bed came out ok though, no more wires hanging out of the wall.

Can the insulation between the cab and box be seen from the outside? Can you post picks from the outside looking in between the cab and box and or describe what and how you did the insulation. Thanks in advance...love this build thread.

I have an accordion seal between the box and cab.

From the outside


And inside

But the water pulses a bit, may look into an accumulator tank eventually, but my god its so much QUIETER!...
I added an accumulator to mine this spring. I love it. RV accumulators seemed small to me (Like .65L or something stupid). I got this 2 gallon one for the same price. It's great. Can run the sink at low flow without pulsing the shit out of the pump. The wife likes it because she can use water during the night without running the pump and waking up the kids. It helped the flow in the shower too, especially if you run it for a few minutes, then shut it off and let pressure build while soaping up.
It also leaves my options open for a higher flow pump in the future.

Wouldn't a small accumulator have an easier time suppressing pump pulses at low flow as opposed to high flow?

I guess it's time for me to read up on accumulator sizing.

No idea on sizing them, but the expansion tank just makes the pump not needed for the first 1.75 gallons or whatever till the pressure drops. What pressure are you running on the air side of it? FWIW its supposed to match the delivery pressure.

I dont have room for a two gallon tank..... Maybe not even the small accumulator....

Right. It just increases the time between the low pressure "on" and high pressure "off" set points. The pump is positive displacement. With only the pipes for capacitance in the system, the pump can bang between the set points while trying to put out more flow than your faucet is taking. The accumulator just takes the extra flow and stores it.

The instructions said to set the bladder within 2 psi of the delivery pressure. My pump is supposed to make 50 psi, according to the specs sheet. In reality, it's more like 35 or 40 psi. I set the bladder based off the high shut off pressure. Guys say you can play with the bladder pressure to get the most capacity possible. I kind of set it and forgot about it. lol

If you're going to the overland rally thing, do like the overlanders, and make your own out of ABS bro!

:D I have a real outdoor shower..... With a hot water heater!

Good, just dont leave them at the factory 2 psi or whatever they put in them, they wear out quick if the pressure isnt close to delivery pressure.

You saved that pass through upholstery job, it had me scratching my head with the trim-less picture. I was thinking this guy does super clean work on all the other stuff he does then throws this curtain around the hole with staples and shit everywhere....

I should have known better.
