Page 18 Royal Series Water Temperature Control Units
Ferrous piping is recommended to minimize galvanic action. If
piping must be copper, use dielectric unions at the unit.
3-5 Piping Considerations for High Mobility
Installations
Mobile Royal Series systems must use high quality hose rated for
at least 150 psig and 250°F (1,034.25 kPa/10.34 bars and 121ºC).
Special 300°F (149ºC) high temperature Royal Series systems
must use hosing rated at 150 psig and 300°F (1,034.25 kPa/10.34
bars and 149ºC) or greater.
Quick disconnects may be used for mobility, although they cause
a drop in pressure. If used, they must be sized carefully to
minimize pressure drop. Don’t use quick disconnects with check
valves unless absolutely necessary.
! CAUTION
Non-relieving quick connect fittings or check valves on the water supply
must have a pressure relief piped to the drain.
Failure to do so could result in a dangerous over-pressure condition!
3-6 Process Water Considerations
Raw Water
Water treatment is vital in any piping system. In some cases, raw
water may be used in the system without problems; in other cases,
it can result in large deposits of scale and corrosion.

treatment options.
Distilled Water
Non-ferrous (brass, copper, or high-temperature plastic) piping is
recommended for distilled water processes.
