Flow rate through 1/2 HP chiller

[Thomashtom]

Hi any idea what would be the maximum GPH you could put through a 1/2 HP chiller? thanks for your help. Tom

They all vary but I'd shoot for around 400-600

 

[Thomashtom]

its a oceanic chiller. i thought i could go a lot higher than that? Thanks

What does the manual say? (Or what model is it, so we don't have to guess?)

 

[Thomashtom]

yeah thats the thing, no manual bought it used and Oceanic does not exist anymore. Will get Model # when i get home from work. Thanks

For a chiller that large the flow rates will need to be quite high. Also will depend on the size of the input/output. My 3/4HP chiller, for example, is plumbed with 1 1/2" PVC and requires a MIN of 1,200 gph. At 500 gph, I'd think you'd run a real chance of icing up a 1/2HP unit. So, if it has 1" in and out I would think you'd want to have at least 1,000 gph. I'm not sure there is a max, beyond that which the native piping can handle.

I heard that Oceanic's were probably Hailea chillers....

Hailea HC chillers have strong metal chassis with a housing of
contemporary design,ensuring the chiller does not look out of place in
any surroundings and as with other cooling units,our chillers-the HC
series use the environmental friendly refrigerant R134a.

Lower noise design,whilst the digital temperature ontroller ensures
that the selected temperature is maintained.

The rate of flow is decided according to the max jet of the pump

(immersible power filter) and the circulation equipment.

HC-500A

200~1200L

1/2HP

R134a

220~240V(110~120V)

1200~3000L/H

50Hz(60Hz)

22kg

2.4A(4.4A)

475×360×490mm

1200-3000L/H = 300-750 GPH

Thanks i appreciate it wow i am getting a wide range of GPH from 300 to 1500 gph.

I was at 950-1000 GPH on my 1/2 HP AquaLogic - Mag 12 (or Laguna 1350) with some normal sump-to-tank head plus the head from the chiller chamber. It would still drop the water about 3-4 degrees before entering the tank.

I would go with whatever you have, track the drop and make sure that it is not too much, or too little. If it only drops a degree, or even less, then you are too fast. If it drops 10 degrees, then too slow.

 

[Thomashtom]

Ok thanks, will take temp of water entering and leaving. Will look for a 3-4 degree drop is that correct. Thanks for your help. Tom

I think the most important thing is that the delta is not too high. I experimented with slow flow through my trade winds 3/4 and lost my nerve when the internal temp dropped below 60 F. Whether the temp drop is 3-4 degrees or 1 degree as a consequence of flow makes absolutely no difference to the chillers ability to cool the water volume - in fact, I'd argue that the latter is better. BTUs are BTUs. I'd use the native plumbing on the unit to guide my flow rates.
