Question on chiller and flowrate

[jowy]

Hi guys,

May i ask.. what if the flowrate is over the recommended flowrate of the chiller, will be harm my chiller?

[Wolfgangs246]

I don't think it will harm your chiller in the short term but if the flow rate is a lot faster than your recommended flow rate, what might happen is that the water won't be cooled sufficiently the first time it goes through the chiller.

This just means your chiller will be running longer than necessary which might result in reduce lifespan of the equipment.

But don't forget that your flowrate will be reduced because your system will have to pump the water through your entire system meaning:

Tank-->Filtration Canister (assuming an external one) --> Chiller --> Back to tank.

So your actual flowrate may be lower depending on how many of these components of the filtration system are above/below, close/far from the tank.

Hi wolf,

This is the setup i have.. but currently my chiller got problem.. went to change a new 1... now waiting for the person to call me to go collect

Hi,

May i know is it normal for my chiller to kick start and stop every few mins.

[Wolfgangs246]

It shouldn't be doing that every few minutes. In my experience, the chiller will run for a long time once you introduce it to the system. But after that it shouldn't turn on more then 1-2 times every hour. Depending on what conditions might make your tank water rise. But every few minutes is definitely not normally. It could be a sign that your water flow is too slow.

I not sure what happen also.
Dont know either my thermometer not accurate or wad..
It just kick in almost every few min.. maybe cos my chiller does not have 0.1 decimal place.

It is not normal. You might have chiller not powerful enough to cool the tank.

my tank is only 1.5ft..
i suspect is my thermostat having problem.
As after it kick start from 25degree.. drop to 24degree.. it stop..
just around 3min later.. it change to 25degree again.

It is an issue surrounding chiller unless your temperature can drop 1 degree in 3 minutes which is very fast. But it is possible because it is only 1.5 feet. Things can happened quicker.

My tank temperature show alot diff... the surrounding of the chiller will affect the temperature also?

[barmby]

What is the difference between tank temperature and chiller temperature?

I don't get it? Surrounding of the chiller affects the temperature of what ?

[jowy]

my water temp in tank is 24.9 to 25.. when i set it at 24 degree.
when it kick start at 25degree(show on the chiller).. it stop at 24degree(on the chiller)
but my water temp still remain the same.
i mean the surrounding of the chiller will affect the thermostats also?

[barmby]

No. More like the surrounding of the tank will affect the kick in ...depend how hot, and fast your tank can get.

[jowy]

the surrounding of my tank are ok.. never really affect much on the temperature.
