digital power controller

[benpandaae86]

The sparkys at work are putting together a digital temp controller for me what temp.

should it be run at??

Where should it be positioned to the element??

it will have
Switch for on and off
digital temp controller
contact for switching
light to show it has power
and temp probe in the boiler

(Yes i have a dodgy kk element i will get one or 2 of macs when i can)

a digital temp controller ???

alcohol % controls temp

think you want a power controller ???

Just slow up a bit champ, you can not run a still by boiler temps.

have a read of the following link mate

What you want is a voltage controller, not a temp controller.

Hopefully one of our resident sparkies can set you straight.

Cheers.

My bad its a voltage controler with digital guage that uses a probe to sense temp and contactor to regulate power to the element to adjust temp

[Meatheadinc]

I think you have missed something ?

The wash will boil at a temp determined by the % of alcohol and the temp will increase during the run as the alcohol % decreases

Hence if you regulate the temp ...... you will get no output.

The voltage controller can regulate power input and flow output, it cannot regulate the temp..

Ok cool

When i last ran my keg boiler it was pushing out 3l a hr out of a small reflux head with extension tower so was tryn to slow it down a bit till i build something bigger

yes me too 8-}

That controller would be good for something like a fermenter fridge, or something that would be used to keep a temperature steady and constant. As the previous comments say, that is not how to control a still. The temperature constantly changes in the boiler, so a fixed temperature controller would effectively stop distilling once the temperature is exceeded, not ideal or practical.

Search Voltage Controllers, heaps of information in here on them too.

Forget about temp controlling at all mate
for your power side of things, you want to focus on your voltage
You need a circuit to regulate the voltage, so an SSR (with a heat sink) and a potentiometer housed in an enclosure is your easiest way down this path
You can add an analogue or digital voltmeter to display the volts you're currently running at

Save the temp control for the condensing side of things, not your power

Ok thanks i read the post and i understand a lot better now

Thank you. So simple.
