My DIY Chiller

[ef_med2001]

hi guys, i'm new here. and here is my diy chiller. i built it from AC outdoor unit. it's 1/2 hp.

this is the diagram

the titanium coil

i put the coil submersed in the sump

digital controller

the probe

it takes 30-45 minutes to chill 120x50x50 (cm) main tank, and 96x25x37 (cm) from 29C to 25C

what do u think?

Great DIY! Can i know where you get the Ti coil from? Btw how long has the system been running?

[leochngyh]

How much you got the ti coil? I believe is not cheap..

Hi. Welcome to SRC.

Would appreciate if more details can be given. I am sure most of us here will be interested. I know I am.

How well does it work? Comparison if possible, otherwise your personal take on it will be more than enough. How much does it cost? How exactly you hooked up everything.

Can also advise what is the running cost like compared to the conventional chiller?

Hey!! great DIY!! how about adding more insulation tubing to the vertical part of the titanium coil? minimise energy loss

merry Christmas!!

thanks guys, i forgot to say that i'm from indonesia.

and sorry for my bad english

i found this forum about 2 days ago, and i think this forum is great!

i bought that coil from my friend, whom from indonesia too. it's about 1.500.000 rupiahs (in SGD, it's about 250)

I used to use Resun CL280 for my tank. for the first 8 month, it was nice. it can chill my tank from 30-25 for 2 hours. after that, i found that it couldn't do its job well anymore. 24 hours running, and could only reach 28C! and i think it's sucks! my mother wanted to "kill" me because of its electric bill

i've tried to get it repaired, but none of ac technicians in my city can repair it. and there's no resun service centre in my country .it made me mad!

then i did a search in RC, i found so many thread about great diy chiller. then i made this chiller with my AC technicians. the titanium was the hardest part to find. fortunately i managed to find it

i got the digital controller and probe from the cl-280. the titanium coil in it isn't enough for 1/2 hp.

this diy has been running in my tank for about 3 months, and i haven't found any problem yet.

the total cost is 3000.000 rupiahs (about SGD 500). quite expensive, but i think i got what i paid

resun cl-650 is about 3000.000 rupiahs (SGD 500) in indonesia, but remember that it's only 1/6 hp!

why do i have to pay SGD500 for 1/6hp if i can get 1/2 hp at the same price

it only runs for about 4-5 hours a day in my tank.
