You really don't need to do thatI have two chillers here I will run in parallel.
New grow hydroponic options for hot climate...

Why not? I have two units, it makes sense to me - if one fails, then the other one will keep working.

Cause your chillers aren't gonna fail. Just use one. If it shits the bed, use the other. What brand and HP are they?

It's too hot here my friend for fun.... 97F at 6am is no joke to wake up to.
I just thought running them in parallel is a good way to have a backup without having to mess around unplugging pipes, etc.?

it depends. are you guys monitoring the grow daily? every hour? all the time?It's too hot here my friend for fun.... 97F at 6am is no joke to wake up to.

i'd keep the second one fresh and ready to go.

I'll check tonight when I'm home on the make and HP.
The issue here is the electric is very bad, we often get surges and brownouts, things always blow up here. I run my expensive led lights on two huge 3000V APS UP's to protect them, however the chillers use too much power to run via a UPS. I do have a safety cut off switch for the chillers, but it's still possible they can be damaged.

Will be monitoring it 24/7 via cctv / bluelab guardian, etc. However, sometimes I work away for a week at a time so looking to build a system that is as falilproof as possible.

sounds like you got the cash to put in a propane back up generator for this op. instant switch over. or diesel if that's easier to obtain.

We have a 35KVA diesel generator on site. It's not instant switch over, takes about 5 seconds to kick in.

Whatever you do I hope you charge top dollar because it sounds expensive to produce weed indoors where you are. Hella worth it though...

Ya I'd like to know. I'm surprised you don't know off the top of your head at least the HP. How many gallons in the system to chill again?

The most likely way they would get damaged is if the power went off and right back on. They can experience a condition called rotor lock where the compressor will strain to fight the pressure in the system during startup. A delay on off control is the way around this. It will have a delay after the power goes out (not when it comes back on). This prevents the compressor from restarting without having a few minutes to allow the system pressure to equalize. A good insurance for any refrigerant compressor. Easily wired with a contactor on the power feed for the chiller.

No idea, I bought the biggest ones I could at the time.
In the previous setup I had I was chilling 1000L of water.I have a 500L reservoir for the new system.

Thanks man. Normally here it's brown-outs (under voltage) that kills the compressor. We use safety cut switches, so if the voltage falls under 200V then it kills the power. I'll have to check if the safety cut has a delay built in when re-supplying power to stop what you say happening.

MOST modern compressors, once losing power, have an automatic 3min delay before starting the compressor again. Usually called a standby mode.

Hopefully my cheapo chinese chillers have this built in.
