what maintenance do chillers need?

zeusfc · 08/26/2007, 04:25 AM

my chiller has been running for about 15 months now, and i'm wondering whether they need any maintenance at all... for instance, my car and house air-con have both been re-gassed in that time.
please, no guesswork, can anyone tell me hard facts?

the unit is a titan 150, and i brought it S/H but unused, with no packaging and no info

They don't need to be recharged ever unless there is a leak in the system.Condenser coil needs to be cleaned.And motor oiled every two years if applicable.I am an hvac tech so no guesswork here,LOL.

brilliant! i remember now doing "deep cleans" at the supermarket... the 'fridge engineers coming in and blasting the coils with compressed air to shift all the dust!
cheers!

I backflushed mine last year, and a TON of crud came out. I'll do it again this year before the summer's over.

To backflush, I used my waterchange pump, and some tap water, and pumped water into the 'out' fitting. The 'in' fitting was attached to a hose that went to the drain. Once I was finished, I ran a bit of saltwater through the chiller before hooking it back up to my system in the correct way. I was quite surprised at the amount of scale and 'crud' that rinsed away. Peering in the fitting with a flashlight before and after flushing made me feel confident that I did something useful.
