Chilled Water Piping Recommendations
Drainage
A large capacity drain must be provided for water vessel
drain-down during shutdown or repair. The evaporator is
provided with drain connections. An air vent on top of the
evaporator water box prevents vacuum by removing air from
evaporator for complete drainage.
Water Treatment
In the evaporator the following material are in contact with
water:
• Water boxes are made of cast iron (GJL250 EN-code)
• Tube plates are made of steel (P265GH code)
• Tubes are made of copper
• Turbulators when present in evaporator tubes are made
of phosphorous brass.
When the unit is supplied with hydraulic module, the
following additional materials are in contact with water:
• Pump frame and connections are made of cast iron
• Water pipes are made of iron
• Pipe sealings are made of EPDM rubber (ethylene
propylene diene monomer rubber)
• Pump sealings are made of silicon carbide
• Strainer is made of stainless steel
Dirt, scale, products of corrosion, and other foreign material
will adversely affect heat transfer between the water and
system components. Foreign matter in the chilled-water
system can also increase pressure drop and consequently,
reduce water flow. Proper water treatment must be
determined locally, depending on the type of system and
local water characteristics.
Neither salt nor brackish water is recommended for use
in Trane air-cooled chillers. Use of either will lead to an
unpredictably shorter life cycle. Trane encourages the
employment of a reputable water treatment specialist,
familiar with local water conditions, to assist in this
determination and in the establishment of a proper water
treatment program.
CAUTION!
If using an acidic commercial flushing solution,
construct a temporary bypass around the unit to prevent
damage to internal components of the evaporator. Trane
assumes no responsibility for equipment failures which
results from untreated or improperly treated water or saline
or brackish water. If calcium chloride is used for water
treatment, an applicable corrosion inhibitor must also be
used. Failure to do so may result in damage to system
components. Do not use untreated or improperly treated
water. Equipment damage may occur.
