blondmyth Posted March 6, 2013 Share Posted March 6, 2013 My new resun cl-280 takes very long to chill even 1 degree when first operational. about 20 mins to chill from 32 to 31 degrees? and another 30 mins to chill from 31 to 30 degrees? thats 1 hour to chill 2 degrees. using a 2000lph atman pump. flowrate should be fast enough. what seems to be the problem? external thermostat required? thanks all.

SRC Member [V]tEc Posted March 6, 2013 SRC Member Share Posted March 6, 2013 Check the flowrate for your chiller. Fast flowrate dont mean shorter chilling time. 1 Quote Link to comment Share on other sites More sharing options...
reby Posted March 6, 2013 Share Posted March 6, 2013 U need to change to a smaller pump bro less than 1000 will be good... Quote Link to comment Share on other sites More sharing options...
blondmyth Posted March 6, 2013 Author Share Posted March 6, 2013 How long does it normally take to chill one or two degrees for example? Read that for my chillers model, 2000lph is ideal Quote Link to comment Share on other sites More sharing options...
SRC Member [V]tEc Posted March 6, 2013 SRC Member Share Posted March 6, 2013 How long does it normally take to chill one or two degrees for example? Read that for my chillers model, 2000lph is ideal Time taken to chill down 1 degree depends on few factors. Tank heat load, tank water vol etc. My resun 450 takes about 15min to chill down 1 degree and rest for about 45min. To see if u are using the right chiller, worse case is running time vs standby time is 1 : 1. Example if your chiller run for 2 hrs but rest for only 1 hr, then high chance your chiller is undersize or due for gas top up. 2000l/hr is for bigger hp like 1/4 or 1/2hp. Not sure where u read it, but online states cl280 pump required is 500l/hr Quote Link to comment Share on other sites More sharing options...
I love angel Posted March 6, 2013 Share Posted March 6, 2013 How big is the tank? Quote Link to comment Share on other sites More sharing options...
zabz01 Posted March 7, 2013 Share Posted March 7, 2013 Hi bro, Nothing much to worry about... Naturally, it will take awhile for the chiller to chill down your entire water volume for the first operational. Once the entire volume of water run through the chiller, eventually you will notice the kick-in time will decrease. Resun CL280 pump recommendation is only 1500L/hr and you have mentioned yours is 2000L/hr, then should be enough unless you have a T-connection that can lower the flow rate.

SRC Member spkentchai Posted March 7, 2013 SRC Member Share Posted March 7, 2013 This chiller should be used for 3ft or smaller tank....any bigger will be not effective to cool down the tank. Average temperature ts 27deg and cool-down around 30-45 mins.... standby time 1-2hrs Quote -5x1.5x2ft Tank 5x2.5x2 Full Height Tank Link to comment Share on other sites More sharing options...
blondmyth Posted March 7, 2013 Author Share Posted March 7, 2013 Thanks spkentchai and zabz. Tank is small, 2 by 1.5 by 1.5ft Quote Link to comment Share on other sites More sharing options...
建沅 Posted March 19, 2013 Share Posted March 19, 2013 From my experience, the ambience temperature will also affect the rate of chilling down the water. And where chiller is being placed. Heat produced by equipment will also add on to it. Like what the other has advise, higher LPH does not mean a faster cool down length. Modifying with an external thermostat and taking temperature reading straight from the tank will ensure a more accurate temperature reading.

SRC Member yiocs Posted April 24, 2013 SRC Member Share Posted April 24, 2013 I think ur flow rate too fast... Quote Link to comment Share on other sites More sharing options...
