Chillers vs. Water Recirculators
What’s the difference between a chiller and a water recirculator?
The major difference between the two is whether or not the unit contains a refrigerant.
An actual CHILLER will have a compressor and a pump to actively remove heat from the liquid flowing through it, using a refrigerant (much the same way a refrigerator or a drinking fountain works).
A WATER RECIRCULATOR does just that; it recirculates coolant through a radiator (much like the radiator in your car). It passively cools liquid by using a heat exchanger and cooling fins. |
Do I need a chiller or a recirculator?
There is no simple rule to determine whether you need a chiller or a recirculator. If you are welding in high production, welding aluminum, or other important or exotic applications, a chiller is the clear choice. If the production rate is low, or the machine is used infrequently, a recirculator is probably fine. Please contact us for details. |

Chiller Sizing
A general rule for sizing a chiller is that, for every 100KVA of welder, you should have about a 1-ton chiller. For example, if you want to cool 4 welders that are 100KVA each, you will need a 4-ton chiller. If you want to cool a 300KVA machine, you will need a 3-ton chiller. |
