Koolance EXC800 Recirculating Chiller - Reviews

bladesofglory

HI GUys

I ordered the koolance exc 800 recirculating chiller yesterday afternoon, so I'm hoping to drop temps and post some reviews of the device to see is it a worth while investment for ultimate overclocks.

As soon as I have it running ill post pics and thoughts, and of course stats on cooling cpu on load.
Some spec below and pics






Koolance's EXC-800 is a portable recirculating liquid chiller rated at 800W, or 2730 BTU/hr (@25°;C liquid & ambient). Chiller control is based on one of four configurable temperature methods, including the option to lock liquid to ambient for avoiding condensation, or to an external K-type thermocouple sensor (not included). The integrated pump is a Koolance PMP-500, with a maximum coolant output from the unit of 11L/min (2.9 gal/min) and 7.5m (24.6ft) of static head.

Along with the local temperatures and user set-point, EXC-800 can report internal coolant flow rate, pump RPM, and condenser fan RPM on a customizable 2-line OLED display. An adjustable relay trigger output on the rear of the unit is available based on temperature.

Cooling capacity: 800W (2730BTU/hr) @ 25°C liquid/ambient
Temperature options: liquid set-point (1 to 50°C), optional external thermocouple set-point (1 to 149°C), liquid and ambient delta-T (± -50 to 50°C), external sensor and ambient delta-T (± -50 to 50°C).
Select only values you want displayed on the front 2-line OLED display (fixed or rotating)
Adjust pump speed with 10 level increments
Show pump impeller speed in RPM
Show coolant flow rate in LPM/GPM
Show condenser fan speed in RPM
Adjust audio alarm based on temperatures
Relay trigger can be configured as NO or NC and adjusted based on temperatures
Refrigerant: R-134a
Power input: 120VAC, 60Hz
Maximum power consumption (approximate): 450W @ 25°C, 650W @ 35°C
Designed for an operational temperature range of 0-40°C (ambient and liquid)
Reservoir capacity: 3 liters
G 1/4 BSPP threads on back for fittings
NOTE: Requires 120VAC, 60Hz input power. Keep unit upright at all times, and for at least 24 hours before applying power to ensure sufficient oil reaches the compressor.

Your aware we are 240 volt DC here right?

Serephucus

Actually we're 240 AC, but point made; that cooler won't work here. Turn it on when plugged in and you'll fry it.

You have heard of a converter right!!!

Serephucus

Of course, but they're not the cheapest from what I've seen, and can be a little messy at times from what I've heard too. You know Overclockers, Specialtech, and WatercoolingUK all sell UK compatible chillers, right?

Yes but there not a recirculating chiller, i.e need a pump.

ps, Converters are NOT expensive. check amazon

You do realize the whole electricity rage in Ireland is based on transformers, of step up and down voltage transformers.

Sure go nuts. I've had nothing but horrible experiences from cheap converters for sensitive electronics.

I'm also a little dubious of a product brought to market with 0 reviews.

In the meantime, do some overclocking with your rads in ice water :P

Its a transformer Mate not a converter, but normally cheap items are cheap for a reason.

Serephucus

I think he means the water chiller.

We all know he meant transformer.
The real question is why you appear to be so touchy about anyone questioning your methods.

Well I didn't know. I'm not touchy just explaining my reasons.

Genghiz Cohen

You do come across as a bit agressive though. Maybe I'm reading you wrong

Anyway, whats the plan for mounting it?
Will you connect it directly to your loop or will it chill the air going to your rads?

Well on the instructions it just gets connected to the Water-block. It has the res, pump and of course the chiller in one, So im just gonna sit it beside the desktop or maybe place a mounting bracket right on top of the case.

Im just looking to get those temps down, and of course I will need to insulate for condensation if I go below ambient

BloodBath

There's not much point buying it if you aren't going below ambient. Good rads alone should bring water temps close to ambient.

Ah yeah I know, Im gonna run it low enuf in order to gain good temps, as at the moment the rads are no bloody good, I need chiller intervention in order to achieve results.

Anyone ever use one before?

Serephucus

How much rad have you got again? I find it difficult to think they'd be "no bloody good".

Im using 1 x 480 and 1 x 240,

Serephucus

CPU and two GPUs, yeah?

Yeah mate

Serephucus

Then you're doing it wrong. That's a ****tonne of rad for that amount of component.

What pump and fans have you got?

My room is a very hot room, so regardless of how many rads I have the ambient temp is just way to high. I also wanna point out Im running my 3970 @ 5ghz with gpus over @ 1167mhz and a further 2 on the way,

I'm using penetrator fans along with a d5 pump.

So its the only way lad

BloodBath

How low can you go before condensation starts being an issue?

You just need to insulate it, and don't go to low below ambient temp.

Key is good insulation and your grand.

How many threads do you need for this build,it's been said a hundred times. Stop calling people mate.

Have a breather will you,

Pic of your rig? Good chance airflow setup is the cause Id say.

Airflow has feck all to do with it, if the room is close to 30C, you can have all the rad and fans you want, your never gonna drop below room ambient

I'm not going to say what's on my mind (I've gotten smacked for that before) but sufficed to say you're completely wrong. The fact that you can build that sort of machine, and not know this, is astounding.

Post a picture, then we'll talk.
