WTS: Hailea 300A Chiller (1/4 HP)

[Alvin Koh]

Hi all,

I would like to sell the following Hailea 300A chiller that I bought from another hobbyist when it was ~6 months old in mid-2009 and tested to be in good working/exterior condition. Manufacture date of the chiller is June 2008 (2.5yrs exactly), the date of purchase is probably a few months later.

Asking Price: $180 (including brand new external sensor).
Location: Clementi/West for self-collection at my home location.
Condition: 8/10 (minor scuff marks, screws with surface abrasion - no rust)
Contact: Please reply to this thread, PM or SMS me at 969-three-three-zero-zero-one and I will update this thread accordingly. Available for immediate collection.


More details:
It was kept in storage when I shifted home and I collected it just last week with the intention to use in my upcoming 3'x1.5' setup. The chiller was tested with a large pail of freshwater and a 2028 filter as pump - cooling to 26 DegC.

I also bought a brand new external thermistor (sensor) 4 days back and paired it with the same connector so it can be plugged directly to the unit for much more accurate/precise measurement of the tank temperature - tested and working well with the full intention to use in my setup.

Reason for selling is because I've downsized my plans from 4ft to 3ft and just realised yesterday that the cabinet is going to be tight with all the equipment. I've gotten a Teco 1/5HP chiller today instead which has a smaller footprint and still sufficient for my tank volume.

Photos (just taken):


Comes with brand new external sensor/thermister which can be placed in-sump/tank.


Display panel plastic film still intact and not peeled off.


Manufacture date: 2008/06/03


Fins are very clean thanks to previous owner. They were in that condition like that since I collected the chiller - previous owner used for ~6 months.


Connector of the original in-built sensor which can be plugged out and replaced with the external sensor.


External sensor: FOX FS-200N (NTC) bought from Sim Lim Tower at ~$20, wired at one of the shops with the same connector.

I think it can be used on the Resun chillers (if there are no significant differences in the model number of the external sensor), however, I have no prior experience with Resun chillers. The 2-wire connectors are however identical.

I did consult BarraCuda & checked out Shadow's blog @
http://aquatic-art.blogspot.com/2008...5-minutes.html for details on obtaining the sensor. There is a slight difference in the newer probe (pointed tip) which is surposed to increase the response rate - but is probably not significantly in a chiller monitoring environment which is gradual. I also added an additional electrical shrink tube halfway down the probe for better water-proofing.

Hi. Can advice any noise during the cut in or cut out?

Hi SFC,

I will try to describe the noises I can pick up from the HC300A.

1) During cut in - fan starts up, increasing air flow noise in 2-3 seconds until it reaches a constant level. No knocking.

2) During running - The sound is a combination of fan spinning (cutting air) and air suction from the front/side panels. There is also a softer but noticable huming/zinging sound (like old-type of fridge). The Teco which I just hooked up, doesn't have this zinging sound at all which makes it quieter.

3) During cut out - fan slows down, no unusual vibrations/knocking.

Chiller reserved by member Troyz to be collected on Monday. Thanks for looking.
