The de-super on third stage was in case you would use R1150, do you plan to use R1150 with the R23 TEV?Originally Posted by bazx
thanks very much for all the work here clem
i will be going with the r23 tev and will do as you suggest for the de-super on the third stage
thanks baz
yes sorry a tev r23

Made a bit of progress
Base cover
Commando plugs
Removable control box
Wheels with braking system
The base cover is made in two half’s from aluminum sheet which has been lacquered to keep its finish
There is one commando socket for each compressor this will allow me to spread the units load when being used in other location/events
Also allows me to remove all cabling when on the move
As I am running out of space on the lower level I have opted for a removable control box
Which will house all the capacitor, breakers ect
As you can see from the images there are plugs going into the unit which allow power into the control box and then send it back out to the compressors, fans and switches
This feature will help during construction and for any maintenance of the cascade when finished

Looking very good baz, can’t wait to get my hands on the control box to do some electrics, this idea will work very well and if needed will give you the option to remove the electrical box with ease at anytime by just removing the Kettle plugs.
OMG just wow.
If you have a cooling question or concern feel free to contact me.
emmm, ill say again love it
A perfect work of art! Truly amazing!

I'm blown away bazxAre you keeping count on the costs?? I'd be interested in final numbers on this one.
thanks lads
ron
trying not to think about the cost of this unit
but i am trying very hard with this one to learn from all of my mistakes with my earlier cascades
my last 3 stage i could not get to anything if it needed work
so with this unit i want to be able to get to any part with out a compleate strip down

Paul (sacha) came over today with the control box all wired up
And I can’t say how happy I am with the work he has put into this unit
After we had installed the control box he went on to wire in all the fans,
And compressors
Thanks dude
It’s been a while since my last update so here is the rest of the cascade up to date
All that’s missing from the lower level is the expansion tank for the R14
So I have been able to move on to the second level where the 2x plate HX will be installed
Along with the evaporator and suction mount/dismount housing
I have also built the top frame which is removable if needed
Once the top level is underway the frame will be off for powder coating along with the
Gauge and side panels

i cannot tell you how good it feels to have made it to the uper level of this unit
the lower and chassis seemed to go on forever

Wow that is beautiful, what a beast. The electrical, wow
Whats on the top right (3 things) of the control box? And great job, so amazingly done.

Magnetic contactors.
Sacha35 did a superb job on the wiring & components ,Neat,securely mounted and labeled. The way it should be......

Looking nice!

Fantastic job
What a work of art, you are a real master baz.
Speechless on the quality of the wiring, piping and general design. Flawless.

Sorry I don't do commercial HVAC, but what are the magnetic contractors for?

Hi nOOb
A contactor is an electrically controlled switch (relay) used for switching a power circuit. A contactor is activated by a control input which is a lower voltage / current than that which the contactor is switching.
Contactors come in many forms with varying capacities and features.
Contactors range from having a breaking current of several amps and volts to thousands of amps and many kilovolts.
The physical size of contactors ranges from a few inches to the size of a small car.
Contactors are used to control electric motors, lighting, heating, capacitor banks, and other electrical loads.
The use of contactor’s is normally for large current loads, the idea is that you can have a large load that will be switched via the contactor which is just a magnetic coil that will close the contacts when switched with very little current pull on the coil.
So the idea is you can have any given load providing the contactor is rated for that load with a very small load/current being drawn across the switch.
I will give you one example of where this type of contactor is used, large office lighting circuits where the current pull could be any ware up to 30+ amps on one circuit this would not be possible to switch this amount of lights due to the amount of current being pulled across a normal light switch as they are only rated for small loads, by having a contactor this is now possible as the main load/lights will be directly connected to the supply side of the contactor with only the switch switching the coil.
There are so many types of contactor and relays available such as high and low voltage switching so do a bit of a Google on what you are looking for, in the world that we live in playing with high current start-up compressors the contactor make things much easier for us as we are able to switch any amount of load or voltage with only a small switch which reduces the risk of any spiking/arc across the switch it as it is only switching a magnetic coil which normally range from, 12volts up to 415volts.
Ah so it allows you to not need as big a power switch basically? That's all.
