enseng Posted March 8, 2012 Share Posted March 8, 2012 Hi all, Anyone can share what is the different bet. these two? In terms of cooling efficiency, cooling method, prices, noise, heat generated? Thx! Quote Link to comment Share on other sites More sharing options...
SRC Member limsc Posted March 8, 2012 SRC Member Share Posted March 8, 2012 Drop in coil condenser (compressor): Like your home air-con. Can be installed further away and run the air-con pipe to the tank to cool down the water. Just imagine your tank is the fan coil, so you would have the air con trunking running to your tank. Thus wont feel so hot if it is installed in the kitchen or balcony. No feed pump needed. Higher horsepower, usually at least 1 HP. Recommended for bigger tank >3ft. Higher cost too due to higher horsepower but it is more efficient. Chiller: Feed pump needed thus the chiller should be nearer to the tank. Else you would need a larger pump and larger pump add more heat. As it is nearer to your tank. The surroundings would be hotter and noiser unless you installed it further away but normally ppl place it next to tank. Smaller horsepower, from 1/15, 1/10, 1/5, 1/4, 1/3, 1/2 to largest 1 HP. My opinion. So smaller tank = chiller 3ft to 4ft or (maybe even 5ft but a bit tough)= chiller or drop in coil. Larger tank = Drop in coil Quote Link to comment Share on other sites More sharing options...
enseng Posted March 8, 2012 Author Share Posted March 8, 2012 thx bro! how abt cost wise? which is more expensive for a 3ft tank? Quote Link to comment Share on other sites More sharing options...
SRC Member limsc Posted March 8, 2012 SRC Member Share Posted March 8, 2012 Hi bro, cost also depends on the brand of the chiller. For 3ft, I would prefer chiller over drop in coil. Less hassle in terms of setup and (I think) should be cheaper too. But not as efficient and take longer cooling time than drop in coil. Depends on what you want actually.

ystad8 Posted March 19, 2012 Share Posted March 19, 2012 Drop in-coil more efficient. For 1 HP, below 1K(got mine 2 yrs ago). Abt 65% faster in cooling down a 4 by 2.5 by 2.5 FT tank as compared with a 0.75 HP chiller. Been there. Quiet operation and minimal heat.

scfong8 Posted June 11, 2013 Share Posted June 11, 2013 Hi Bro, Re-visiting this topioc again. Do you know of any lfs which will install drop-in coil? Also, can we have one coil for 2 tanks like a mulit spilt? thanks for any advice. Quote Link to comment Share on other sites More sharing options...
SRC Member peacemaker Posted June 11, 2013 SRC Member Share Posted June 11, 2013 Hi Bro, Re-visiting this topioc again. Do you know of any lfs which will install drop-in coil? Also, can we have one coil for 2 tanks like a mulit spilt? thanks for any advice. I have a similar question, but more like cooling the tank and cooling my room. My air-con compressor is down, so I was thinking of replacing it, as well as using it for aquarium. Anyone can share contacts? Quote Link to comment Share on other sites More sharing options...

SRC Supporter Harlequinmania Posted June 11, 2013 SRC Supporter Share Posted June 11, 2013 I have a similar question, but more like cooling the tank and cooling my room. My air-con compressor is down, so I was thinking of replacing it, as well as using it for aquarium. Anyone can share contacts? As far as i know only single unit compressor can be used for aquarium chiller. Mulit split system unit cannot be use together for both aquarium and room air-conditioning for the reason that it need to hook on to the temperature sensor to kick start the chiller.

kraken Posted June 14, 2013 Share Posted June 14, 2013 Inverter systems cannot be controlled by external temperature controller, they rely on the fan coil since the sensor and thermostat is located. As such, for marine cooling using compressor, we can only use non-inverter types (3 stars ratings maximum). for 3ft and above tanks, it is more efficient and cost effective to deploy a compressor cum drop in coil solution for cooling. Other benefits including wife no longer nagging about the chiller's noise and heat in the living room (this is priceless). Quote Link to comment Share on other sites More sharing options...
scfong8 Posted July 5, 2013 Share Posted July 5, 2013 Hi all, Is there any major issue of having a titanium coil vs insulated copper coil? Quote Link to comment Share on other sites More sharing options...
Guest Posted July 6, 2013 Share Posted July 6, 2013 Hi all, Is there any major issue of having a titanium coil vs insulated copper coil? I am using insulated copper coil for about close to 3 year now and so far so good. I personally feel copper cool faster than titanium coil and most importantly it is much cheaper.

I love angel Posted July 6, 2013 Share Posted July 6, 2013 Insulated copper is more or less custom made. So there is more turns or double turns depending on the air guy and yours needs. Therefore will cool faster. That is what I know. Quote Link to comment Share on other sites More sharing options...
idle69 Posted July 6, 2013 Share Posted July 6, 2013 If I still remember from my science classes, copper is a better conductor of heat whereas titanium is a very strong but light metal..so for usage as drop in coil, copper can tranafer de heat away faster but prone to rust n oxidation, while titanium can last so much longer but not as good on heat transfer..

scfong8 Posted July 6, 2013 Share Posted July 6, 2013 Thanks all. I was told that copper coil risked "poisoning" the water if insulator is damaged through wear and tear. Then, all corals will die. Is this a reasonable concern? Quote Link to comment Share on other sites More sharing options...

Is this a reasonable concern? Yes you are right about that as well. That's the down side of using copper insulated coil , and which is also why some still prefer titanium coil. So it depend on the choice and risk you willing to take. Sent from my GT-I9300 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

David5077 Posted July 7, 2013 Share Posted July 7, 2013 does the distance of the condenser to the tank affect the efficiency of the chilling process? Quote Link to comment Share on other sites More sharing options...
Guest Posted July 7, 2013 Share Posted July 7, 2013 does the distance of the condenser to the tank affect the efficiency of the chilling process? Yap, the closer the coil to the compressor the fastest it chill . Sent from my GT-I9300 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
SRC Member triggerfish Posted July 8, 2013 SRC Member Share Posted July 8, 2013 could I clarify with those using a compressor which is located under/near the tank, it uses the traditional 3-pin plug or an isolated power source? thanks Quote Link to comment Share on other sites More sharing options...
dnsfpl Posted July 8, 2013 Share Posted July 8, 2013 why not consider aquarium chiller if you intend to place it near your tank 1 of the few advantages for compressor is heat and noise, but you must place further away from tank Quote Link to comment Share on other sites More sharing options...
