Water Quality

  -  In order to protect the package components in contact with the cooling water against

attack by corrosive and fouling agents, we recommend that the cooling water meet the following quality
standards

Total Dissolved Solids (TDS)..................

<500 ppm

Iron.......................................................

<2 ppm

Total Hardness......................................

<60 ppm

Silica ....................................................

<25 ppm

Oil and Grease......................................

<5 ppm

Sulfate..................................................

<50 ppm

Chloride................................................

<50 ppm

Nitrate...................................................

<2 ppm

Corrosivity.............................................

Langelier Index between 0 to 1

Unlike the internal injection water system, the cooling water system does not have any form of filtration or
treatment.  It is the responsibility of the end user to ensure that cooling water of adequate quality is used.
The water quality tests described in the “RO Water Filtration System”, SECTION 8, may also be used to
monitor the quality of the cooling water.

Water Flow Requirements

cooler core performance:

Notes:

•

 

Estimate of core pressure drop at lower than maximum flowrate = (GPM/GPM max.).

•

 

Flows exceeding maximum rate will cause severe erosion and will void unit warranty.

•

 

Water temperature below 60

°

 F may:

- 

produce excessive cooling and condensate formation, overtaxing the separation 
device and allowing water carryover into the customer pipe works.

- 

result in low water velocities (e.g., to check cooling rate) which promote tube 
fouling.

•

 

Water temperature above 90

°

 F may cause recurring high discharge temperature 

shutdowns.
