    I would say so indeed... not that I am a pro either - I don't own a chiller. BUT - the slower the more effective the chilling...... That's what my logic dictates....

    Well it doesn't actually matter as the amount of heat removed will be the same even if the water is flowing fast.therefore use a smallish pump to save power...will work just as efficient as high flow as long as its not very low or else your livestock will actually feel a cold current in the tank.

    I am using a chiller rated for 1500 litres you can use anything from 1500 litres per hour to 4000 litres per hour.

    Remember you will lose lotsa flow if plumbed correctly which is outside, to have a chiller inside is like having ice in a kettle - total contradiction.

    Keep within mnfr guidelines...

    Note ratings, are slightly overstated:whistling:

    SPECS:
    Titan 1500
    1/2HP
    Electric Power 375 Watt
    Cooling power (watts) 790 watt
    10 C drop up to 240 gallon
    5 C drop up to 450 gallon

    Recommended water flow 200 - 500 gph
    Cooling Gas R 134 A
    Dimensions 15.6"L x 13.6" W x 15.6" H
    Heat Exchanger: Titanium
    Temperature controller: Digital accuracy 1 degree C, Set point in 1 degree steps
    .

    mnfr range: 750-1900L/h
    Depending on pipe run, any head,sytem volume and internal restrictions.
    Pump should deliver as close to 2000L AFTER deducting for all losses described.

    Use pressure rated centrifugal(return type)pump
    Powerhead may work, but with lower confidence levels.

    Thermal insulation(lagging) of pipe from chiller to tank if need be.

    Based on feedback of owners, including those with failed units , discussions with LFS and importer.

    Better to apply slightly higher flow rates.
