Microchiller
Hi all,
Does anyone has any better info, seen or use this product before? It's mainly for Nano-Reef Tanks or Small Aquariums. Saw this while browsing articles for chillers. http://www.fishnfriends.com/FishSpec...es_Chiller.htm Thanks |

This is my DIY integrated chiller into a 1 feet tank, able to achieve down to 22C and temperature can be regulated at higher then 22C, I am running it at 24/25C for good.
Checking the performance, it can achieve 22C even with an internal filter to circulate the water and to introduce heat as in normal operation Showing the cold fin with maximum exposure to the water. It is much cheaper to DIY then to buy such a microchiller. |

EHHK,
Not a problem to show u how to DIY, I had an article making use of the same concept to cool down a tank. This time, I use direct cooling to achieve better result, instead of passing water to cool in a reservior in the old method. However, to DIY a TEM (Themoeletric Module)/Peltier based chiller for 2 feet tank is rather ambition, due to the large amount of heat to be disspated. I know that a bro is using a extra huge TEM to make a chiller good for 2 feet, will get update from him. With our climate, using TEC as an heat exchanger is more realistic to cool down a 1 feet or 1.2 feet, any large size tank will have to resolve the large amount of heat produced. humvee, The heart of the integrated chiller is a TEM which is used as an heat exchanger. I bought my TEm from USA using mail order, I heard that Sim Lim Tower is selling too. Other than this part, it is heat sink and cold fin, which can get from Sim Lim Tower too. An old PC PSU can be used to drive the TEM and fans on heatsink. the_r0ck, I guess from the above replies, you have already known the trick is in TEM, it has one side hot and one side cold. The cold side draw heat from tank to cool the water. Note that by using TEM, lower temperatuer can be achieved compare to cooling fans, and there is no evaporation of water. |

Since you do not use the rest of the voltage trails and only 12V. You are not drawing maximum current and thus you are not operating the PSU at its maximum rate wattage. From my test, using a timing to operate it at 33% of the time, under operation, it draw 8A and the 12V trail drop to 10V. So it is 80W, and since only 33% of the time is operating the effective wattage is 80/3, about 30W. |

Not only CRS needs cold temperature, some exotics plants, killies and moss do better or can only live in cool water. It is really up to oneself to see if the spending on electricity bill is justifiable for the hobby. Not everyone will to spent an overhead on high electrical bill, a months of tens of dollars on electrical bill maybe too much for $0.35 bee shrimps. |
