CHILLED WATER DISTRIBUTION PIPING
The chilled water distribution piping is an important factor in the performance of the water
chiller. Proper piping will prolong the LIFE of your chiller. This chiller is designed to be a
containment free system. The chilled water piping should be the same. NO BLACK
IRON PIPE.
1. If you are installing this water chiller to some existing chiller water lines (Black of
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 evaporator heat exchanger and cause damage to the pump.
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 lose 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. Make sure the hose is rated at least at 150psi or greater. 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. Black Iron will damage the watering
system. Schreiber Engineering will NOT grant the warranty of the chiller if this type of
piping is used.
5. The Chiller is provided with a female piping connection. The connections 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 1”
NPT, then the chilled water lines should be no less.
7. For Dual Stage System, clean the strainer every 3 months or materials start to build up
in strainer (as pictured). The strainer can be located by the Brazed plate heat
exchanger or by the pump discharge.
