I-Vac control box as coolant pump safety device

[hpby98]

For those running a 110v coil, what about running an I-Vac switch. When the cooling pumps running, it enables the element.

If there’s no load on the pump side the element automagically gets cut off

Just an extra level of safety....?.

Technical spec’s:

• Operates from one or two 115Vac 15 Amp mains circuits.
• Power Tool receptacle: rated at 115Vac 15Amps, limited by a 15Amp circuit breaker. Click here to view our technical note on current ratings.
• Vacuum Receptacle: 115Vac. Dust Collector should not exceed 1HP or 5 Peak HP, limited by a 15Amp circuit breaker.
• Turn On Delay (In Auto Mode.) 0.5 seconds to 2.0 seconds.
• Turn Off Delay (In Auto Mode.) Approximately 6.0 seconds.
• Turn On Tool Current threshold in Auto Mode. 0.3 Amps.
• Plastic housing is 4.625” x 4.625” x 1.875” (11.7cms x 11.7 cms x 4.7 cms )
• Housing Material ABS 94VO
• Tool Power Cord 54” (137cms.)
• Vacuum Power Cord 19.5” (50 cms.)

An energized pump does not always produce flow.

A flow switch would be a better safety if you're trying to avoid running the element when there is no flow.

No amount of automation will replace the need to be close to your still and paying attention during operation.

True, but an extra safety factor certainly doesn't hurt. In one former job, I made a mistake which caused a release to be late. I proposed a change to the process to make that particular mistake to be impossible to make. My tech lead's response was that I should just be more careful. "Be more careful" is never an acceptable safety policy if there is a practical way to prevent a dangerous situation.

I've got a similar switch that I use to turn on/off my shop vacc connected to my table saw, and it's great for that application. I expect it would also be great for ensuring that your coolant pump whenever you start heating your boiler.

I think mine is the i-Socket, which is about half the price.

Of course, it only works if you have a 110v plug-in heater on your boiler, and if you have a 110v pump running your coolant. Those who have 220v heaters, or use gas, or use a stove, or use a faucet/hose for cooling water will not be able to use this. So it's not a solution for everybody. But for those who can use it, it seems like a good idea. And it is also darned useful to have around if you do any woodworking.

I agree - just an extra safety just in case

It's probably more $$ than the other one as it can support two 15 amp devices - both your tool and your vacuum, giving much over head

Noted, but it's still better to have something as a secondary safety than nothing

A latched relay and a simple controller reading the condenser outlet temperature can shut the still down for any event that causes vapor to exit the condenser. Once that is set up, other switches can be daisy chained into the circuit, dead man timer, boiler temperature, boiler pressure, whatever takes your fancy.

You know, it *sounds* like you're speakin de english but some of us are simple when it comes to this stuff...

It is less complicated than what you suggested in your OP, so I assumed you would understand it. Have a talk to the electrician you were intending to use to install your proposal.

No electrician required for either the i-Vac in the OP or the i-Socket I suggested. You plug the box into the wall, plug the boiler into the "tool" socket and plug the pump into the "vacuum" socket. Whenever the boiler is turned on, the box detects current flow and automatically turns on the pump. Very simple.

Exactly why I am interested in this to start with

I think I will try this shortly, except run it so that when I turn the pump on, it then enables the boiler.

Reflux runs do tend to take their sweet time!
