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.
