Water treatment
Untreated or insufficiently treated
water, if used in this unit, may cause
scale, slime or algae to accumulate
or cause erosion and corrosion.
As Trane does not know the
components used in the hydraulic
network and the quality of the water
used, we recommend the services of
a qualified water treatment specialist.
The following materials are used in
Trane chillers heat exchangers :
- Stainless steel plates AISI 316,
1.4401 with copper brazing.
- Water piping: copper 99,9 %
- Water connections: brass
Trane will not accept any liability in
regards of damage due to the use of
untreated or improperly treated
water or from the use of saline or
brackish water.
If required, contact your local Trane
Sales Office.
Antifreeze protection
During negative ambient air
temperature chilled water piping
must be fully insulated.
Insure that all safeties are taken to
prevent frost damage during
negative ambient air temperature.
Following system can be used:
- Electrical heater mounted on all
water piping exposed to negative
temperatures.
- Start chilled water pump during
negative ambient air temperature.
- Add ethylene glycol in the chilled
water.
