CHILLED WATER DISTRIBUTION PIPING
The chilled water distribution piping is an important factor in the performance of the water
chiller. Proper piping will add to the LIFE of your chiller. This chiller is designed to be a
containment free system. The chilled water piping should be the same.
1. If you are installing this water chiller to some existing chiller water lines (Black or
galvanized) there is a good chance there will be rust in this system. If you cannot
flush this system clean then it should not be used. A rust contaminated system
will cause damage to the copper evaporator heat exchanger. NO BLACK IRON
PIPE.
2. Should this be a new system and you are installing chilled water piping. We
suggest using PVC piping if allowed. It is a poor conductor of heat, so you do not
loose as much BTU capacity in the movement of the chilled water and there is no
rusting.
Copper line will prevent any rusting but there is greater heat loss. You might want
to insulate these lines.
3. Should the water chiller be installed next to your cooling load? We would suggest
rubber hose. This would prevent any great heat loss. And there would also be no
contamination.
4. If black pipe, galvanize, iron, and steel pipe are your piping of choice, you should
be aware of the corrosiveness of these materials. Never use black iron pipe.
5. Female connections to chiller are brass. If your connections to the chiller are
anything other than, PVC, copper, or rubber hose you should consult with your
local plumbing supplier about the use of dielectric pipe connections when
dissimilar metals are used. If we can be of any assistance with this please call
the manufacturer.
6. Keep in mind you should keep all chilled water lines full size. If your chiller has 2"
NPT, then the chilled water lines should be no less.
