Is it modified with external thermoprobe?
Flowrate of the filter might be the issue with the kick in timing. How long does it rest for till the next cooling down?
Hi everyone, check with you guys whether is it's a norm. My hailea hc-150 need around 30 min to cool from around 25"c to 24"c . I using it for a 2ft tank pair with a eheim 2213. This is my first time using a chiller and it's a gift from my gf brother. Before that, he have been using it for 1yr plus

Nope, it's does not have a external thermoprobe. It's rest about 45min then kick in again. By the way, I set it at "24"c" . So the chiller will only kick in when it's around 25"c.Originally Posted by Jianyuan
But sometime it's take more than half hour to cool from 25"c to 24@c. Is it normal?
Bro jianyuan, currently I monitoring the kick in. It's started just now at 515pm, chiller show 25.1"c. Now at 5:47pm, chiller show 24.8"c. Its take quite sometime for the temperature to drop.
Then should be ok, its normal.
Flowrate issue normally will be 5min on and 15min off.
Sounds like flowrate issue to me too, unless you decide to upgrade your filter.
Alternatively, I've taken up advise to modify my hailea hs28a with external probe.
I was facing a different problem from yours though, my kick in is quite frequent every 10+ mins.
Bro jianyuan, care to share how long it's take for your tank to drop from 25"c to 24"c? Or to your desired temperature?
Hi bro shadow, but for my case mine chiller took very long to decrease for 25"c to 24"c("I set the chiller to kick in at 24"c). Is it like our human aircon, need to top up gas, so as to cool down faster?
I take 16minutes to chill down to 24 degree from 25 degree currently and kick out for nearly 1 hour. Prior to that it takes 6 minutes to chill down one degree and kick out for 13 minutes.
Its possible. I just Google that HC-150 is 1/10 hp and you are cooling 2ft tank (I assume 60x30x36cm). Anyone have similar setup
There may be a few problems. The problem now is that you SHOULD have flowrate issues, as your filter is too weak IMO. However, you did not face, but instead your chiller took much longer time to cool down the water in the chiller reservoir. It clearly means that the chiller is unable to perform efficiently, these can be due to several reasons.
1. Gas need to be top up.
2. Surrounding temp is very high while you set your ideal temp too low.
3. Ventilation is too weak. Hc-150's fan is already considered weak, thus if you still put the chiller in a enclosed area, it's will result in chiller not performing efficiently.
Thats my take on the issue. Correct me if I'm wrong.

Consider if you do solve your chiller efficiency problems, the problem will be flowrate issue. This can be observed by noting the current problem(chiller take if long to chill) to chiller kick in kick out very often(this suggest that your chiller is chilling effectively, but not efficiently because the problem now will be flowrate issues) hope this helps

Hi bro zackzhou, I will like to take the approach of changing the chiller gas first, if it's still don't work. Then I change the filter. But do you know where can I change the gas and what is the damage? Possible to bring down the chiller and top up the gas on the spot? Sorry for so many questions ask, as I keeping some crs and worry they might died off if without chiller for too long.
Or any bros can recommend repairman that come to your house to top up the gas?
Repair man name Andy, one of the hailea distributors. Hp: 9146 5383
Damage on wallet less than $100 I think. Cannot top up on the spot as hailea refrigerant is sealed with no opening. He need to physically create a hole and later seal it up..

Thank bro zackzhou for your contact. Just now, my gf bro pass me a chiller repairguy derrick contact. I called him up and he advise me that hailea chiller is not like our room aircon need to top up. He advise me to check the back of my chiller. If there is warm air blowing out from the back. That mean the gas is still enough, if the air is cold, that mean there is a leakage.
So far my chiller is blowing hot air from the back. He advise me to change the filter and monitor. Guess I go get a 2nd hand filter to test out see
Yesterday i hooked up a eheim 2028 to my chiller to do a test. Result don't seem too good, time needed to cool from 25'c to 24'c need an average of 1hr and a half. After that its rest for half an hour before starting again.
Anyone using the same configuration can share with me the timing needed to cool from 25'c to 24'c? Or advise me what is the problem here.

Did you do a search or read previous thread? You need to modify your chiller with an external temperature sensor. After doing this, your chiller operating time will drop, your chiller standby time will increase from your current timing and your flow rate requirement minimum is 500lt/hr.
If you've learnt, teach, if you have, give.

Hi mod, I have read previous posts and I believe that ehiem 2028 is sufficient to pair up with hailea hc-150c chiller. I know that the default temperature sensor from hailea is not accurate as it's measuring the temperature in the tank inside the chiller.
Maybe I did not make myself clear. Sorry about it. My concern is when I lst got tue chiller. It's doing it's job well, cooling from 25 to 24"c like say in half hour time. That time I using 2213 with the chiller. But recently with 2213 , it's took 1hr plus . Some bros mentioned it's could be the filter flow rate too low. Therefore I change to a 2028 to test. But it's still took 1 hr plus to achieve 24"c. Sighz.
I just want to find out anyone encounter this problem before. Their chilling time take much longer and how they solve it. ^.^
Since the cooling time double from 30 minutes to 1 hour, maybe dust blocking the intake? does the chiller cooling fan working?
Hi TS,
If you had understand my 1st post, you should have understand. I have already stated CLEARLY that right now it is definitely NOT a flowrate issue yet. Why? Because when you hook up 2213 with the chiller, you will definitely face with flowrate problems if your chiller is working will. The sign of flowrate problem are very short kick in/out time(3~6minutes).
But even with possible flowrate issues, your chiller took +/- 1 hour to chiller the water down by 1 degrees.
Let me tell you agin, it's definitely NOT flowrate issue right now. Solve your chiller problem 1st. Shadow is pointing you a highly possible porblem to you. Clean the chiller intake and see how it is again. Although I believe that there are other causes beside this. Goodluck
