Seems that both are using different thermostat circuitries....can tell from the connectors being used...unless same thermostats but different connectors

Here's the thermostat control of the Suncool

yeah..i have to say the Artica staff are very pro and service-oriented..... the mod the mod....works damn well man...lol here's the thermostat control of the Artica

The bad point about these chillers are that they are very noisy.....but Artica recalled my 1/2hp recently to do a mod of the casing/fan to reduce the noise..and noise surely reduced significantly....but it's still audible though..hehe The main intention is for the Suncool to provide cooling for my system should the Artica chiller or water flow through it fail for watever reason.... My Artica fed by a tee-off from my iwaki mx100, is set at 27.6....which means it kicks in at 28.0 and stops at 27.2..... under normal circumstances.....temperature will not rise above 28.0 So i will use an eheim 1262 to feed the suncool and set it to 27.8......meaning it will only kick in should temperatures reach 28.2 and then stops its operation at 27.4 That's double cooling loop

SunCool's label...

Artica's specs label

Here's the Suncool-Daeil..... physically similar....

Have been running the Artica 1/2hp commercial series chiller to my satisfaction and thus got a Daeil-Suncool 1/2hp chiller from a fellow reefer for my 2nd cooling loop.... Here's a picture of my Artica

bro.... yours is probably just a variant of the kole tang... here's a kole with a white tail http://species.fishindex.com/photo_30374ct..._kole_tang.html

yeah....just more stuff to confuse the confused out there http://www.thermaflo.com/interface.shtml Interface Materials - Thermal Compounds and Greases http://www.thermaflo.com/ifmat_grease.shtml Interface Materials - Thermally Conductive Elastomeric Films http://www.thermaflo.com/ifmat_elastomeric.shtml Interface Materials - Phase Change Materials http://www.thermaflo.com/ifmat_phase.shtml Interface Materials - Double Sided Tapes (personal favourite though not the most effective ) http://www.thermaflo.com/ifmat_tape.shtml

heatsink will not help much if you do not have air movement to carry heat off its fins..... what i advise you to do if you want to cool your md30 is to use those AC fans (slightly bigger versions of computer DC fans) in sim lim tower and blow your md30..... and then if you are still not happy with the cooling, then u add the heatsinks...but then it is very difficult to find curved heatsinks like the one i posted made just right for the curvature of the iwakis...

the part in blue shows the water path....water enters the pump from the right and then spins inside and pushed out of the picture, avoiding the hot parts of the motor...

this pic shows the separation between the hot motor block and the portion in contact with water....the water does not run through the hot parts of the pump.....but as you bolt all the parts together....some heat will be passed on from the *front* end (cooler end) of the motor block to this black plastic cyclone path part and that's why you still will have some heat transfer.

fortunately the iwaki water path does not involve contact with the hottest parts of the pump....at the fan end of the body is usually the hottest and at the other end where the big bolts are.....the bolts are rather cool and the water path is actually just making contact with the black *cyclone* path in the picture below and this piece is actually kinda separated from the hot motor block instead of being one-body. So while, there is still some heat transfer, the full heat of the pump is not transferred to the water. *phew*

actually i ran a resun md55 before and it was too hot to touch whereas i went over to touch my friend's iwaki md55 and it was much cooler.... similarly, even weileong has mentioned that his mx70 ran cooler than his previous resun md55. as for your iwaki md30, i got no personal experience with this pump...but if i am not wrong, this pump does not have a fan to cool it, probably that's why you feel that it's hotter?

Indestructible Iwakis

i think we need something like this for our iwakis maybe i see if can order in and then remachine/recut it to clip on some parts of my mx100s

again i must state i feel that both iwakis and RDs have a niche of their own.... like robe has said....iwakis are built for tough and rough use....think of the Mitsubishi heavy vehicle that can pull a container and a ferrari running a championship car tournament....both possess immense power..... but would you use a ferrari to pull a container? or would u use a Misubishi heavy vehicle to run the LeMans? The Iwaki (mitsubishi) being pressure rated, excels at pulling loads under pressure, through restriction, construction obstacles (elaborate piping work) and so on.......whereas the RD (ferrari) excels when it is allowed to fly on a flat open road under little loading and restriction..... the inherent design of the impeller/pump (engine/transmission) of the Iwaki (mitsubishi) gives it the ability to work very well in the lower speed but high torque applications but it loses the edge when it comes to top speed performance of the RD (ferrari).....just like the impeller/pump design of the RDs give it the ability to fly under minimal restrictive applications whereas it will not do as well under what the Iwaki will excel in..... that's why i say both excel at different things. Iwakis are amongst the top choices for pressure rated use.....and RDs are amongst the top choices for non-pressure rated use.

patrick....no point putting the heat sink if you do not have air movement to bring heat off the fins.... putting heat sink with no fan will overheat the pump more than its original configuration. if it is the iwaki fan noise that is irritating you, remove it manually as i said and use quieter fans to blow the pump instead. Then u want to use those turbo fans or big AC fans also can. Adding heat sinks, irregardless of using the inbuilt fan or external fans should help the pump dissipate heat faster. But then it comes to whether is it worth the extra mile to stick the heat sinks painstakingly or just use a more powerful fan instead.

yeah..iwakis are just like Mitsubishi Heavy Industries equipment whereby it's meant for rough and tough use and you can easily find parts for it years down the road..... whereas RDs are less common and more exclusive like italian cars and finding parts for them in future may be a problem.

depends on application lah....if application requires elaborate piping work and great heights or restriction....pressure rated pumps like iwaki do the job best... if application involves minimal piping work, not too high a discharge point and no significant obstruction to flow, non pressure rated pumps will be able to handle lor....in this case RD works fine at low wattages but at a premium price lor.

correction lah.... using the 1500VA....not 750VA... i only connect to my Tunze TS07.... ran past 3 hours in my previous test with no problems on old batteries...still can go longer but i ended the test because seldom got power outage longer than 3hrs in singapore. nonetheless i changed to new batteries before i made a trip to japan end of last year. i don't think i want to deep drain the new batteries....timing wise APC is quite reputable so we can go with their runtimes approximately... http://www.apc.com/products/runtime_for_ex...m?upsfamily=165 says it can run about 5hrs on 50W load on 1500VA....so on lesser loads should pass 5 hrs easily on good batteries.

means outdated link by hardwarezone then....did u ask them to get back to you with updated price?

personally i am using the APC SMART 1500VA
