Pegasus Posted April 17, 2002 Report Share Posted April 17, 2002 How lucky are we. Could get into probs over this, but this guy from another site I'm a member of has no such prob, and because it was so funny, I thought you'd all like to read it. I don't think he'll mind. To put you in the picture, they are talking about chillers, and one guy even suggested putting the tank in the fridge for a few hours a day Musta been a small tank Besides, this is Canada. Don't you know Canada is the land of ice n snow?? Don't let that 90 degree summer stuff fool you. Just haul your tanks outside and park em next to the doghouse full of husky pups and the penguin you rescued from those rabid wolves over on Glacier street. Wolves. bah. humbug. Always scaring the potential young hockey players away from the outdoor hockey rinks. Then again, if a kid isn't man enuff to fight off a few measly wolves for the right to the rink, what kinda lousy hockey player would he turn into anyways.

Caryl Posted April 17, 2002 Author Report Share Posted April 17, 2002 We might not have wolves Pegasus but we have had a few territorial hedgehogs with attitude around our place lately! :lol: Quote Link to comment Share on other sites More sharing options...
WEKA Posted February 12, 2006 Report Share Posted February 12, 2006 I have built a chiller for my 600L cold marine using a unit I salvaged from a small walkin coolroom. The evapourator from inside the coolroom fitted into a section of 250mm pvc pipe with enough room for forty metres of 12mm garden irrigation pipe to be coiled around inside the lenght of it. It stands about 900mm high. Amazing how much pipe you can fit in! The 12mm pipe is split into two parallel circuits to reduce the head on the supply pump. The saltwater runs thru the irrigation pipe which is submerged in freshwater inside the pvc pipe alongwith the fridge evapourator. I have a small pump which circulates the freshwater around inside of the pvc pipe and helps with the heat transfer from the saltwater pipe to the freshwater and then into the fridge piping. I have not finished my set up yet but have had the chiller running thru my sump and it works real well. Had the sump down from 22 to 10deg in about half an hour. The fridge compressor is rated at about 1Kw. Have insulated the outside of the pvc pipe with 25mm foam. Hope you can make sense from all of this. Be happy to pass on the raft of experience I have gained from this part of my project if you are interested. Quote Link to comment Share on other sites More sharing options...
wasp Posted February 12, 2006 Report Share Posted February 12, 2006 Good job Weka! First person I've heard of to make one that actually cools the tank effectively! Quote Link to comment Share on other sites More sharing options...
Feelers Posted February 13, 2006 Report Share Posted February 13, 2006 How much was the old coldroom unit? I have heard that water coolers(ie the ones found in corporate offices ect) are also a good thing, but finding one cheap is the hard part.

suphew Posted February 13, 2006 Report Share Posted February 13, 2006 Haha thats funny, cause I had a water cooler sitting in my Christchurch office, I had it sent up here thinking I would try turning it into a chiller but never bothered so now its in storage.

WEKA Posted February 13, 2006 Report Share Posted February 13, 2006 The coolroom unit did not cost me anything as I rescued it from in front of a front end loader just before it went to the dump. It was one of those things you put in the back of the garage for ten years thinking it may come in usefull one day. I did not even know if it worked so gave it a test run prior to building the heat exchanger. My thoughts are that a water cooler would probably only have enough grunt for a small tank ie 100L. Problem with any marine tank is keeping the salt away from metal pipes. Even stainless does not survive long under these conditions. I will post some pics of my setup to date when I work out how to post them on this site. Quote Link to comment Share on other sites More sharing options...
seahorsemad Posted February 13, 2006 Report Share Posted February 13, 2006 Hi Carol I brought my chiller from a place in australia called coral plantations. I have been told it is not the very best labelled chiller but it is working well for me. Anyway i picked it up for about $600 AUD and shipped it back here through australia post for an extra $100.00 approx (including insurance). It would be worth looking at them as they seem happy to freight internationally, had great service and the price still works out to be alot cheaper than what they are selling for in little old NZ. Good luck Seahorsemad http://www.coralplantations.com/ Quote Link to comment Share on other sites More sharing options...
