Thanks to Peter - bob(nz), I'm now the proud owner of my first Kayl Cascade cooler - 2x 1.7HP unit. This cascade cooling unit was built by fellow Team Australia team mate, Kayl for another team mate youngpro (James) and was then sold to another team mate bob(nz) and now it lands in my hands

While I am busy with work right now, found some time to at least start up the cascade cooler to check if it survived the trip from South Australia to Brisbane

Took a few photos and 11.5 minute edited video of the Kayl Cascade unit starting up - quite noisy . At around ~49 seconds into video I tested out the cold bug bypass switch, so you see a momentary increase in temps to -91.5C mark then I turned it off to end up with coldest temps of -111.6C on evap and -49.3C on first stage.

Power-mate wattage meter measured a peak at startup of 2695 watts, and average operating power consumption measured from the wall was between 1775 - 1795 watts at ~247-249 volts mains power. Checked my electricity box and while I have 1 phase mains (10A) - all my fuses show rated at 16A, so nothing tripped the safety switch.

The compressors definitely put out considerable heat starting off at +55C rising eventually to around +88C to +93C. Definitely will need a fan to cool those compressors.

This will be fun as I've never tried colder than -45C temps with my old Kayl 1/4HP single stage phase change cooler also built by Kayl
