Special Maintenance Tasks. Fluid Cooler Winterization.
Normally fluid coolers are used in the systems, filled with glycol mixture to prevent the system and the fluid cooler
from freezing and, potentially, rupturing, when exposed to temperatures below freezing point.
When fluid cooler is used with media that, when exposed to low temperatures, could freeze (water or lower-
percentage glycol mixture), one way to protect th
e equipment is to drain it (also known as “winterization” of the
equipment).
Though fluid cooler itself is normally equipped with means to be drained properly/fully, it is recommended to have
same means in place for entire system (fluid cooler
– piping – dehumidifier etc.):
•
Have each local high point of the system equipped with means to bleed the air (air bleeding valve etc.)
•
Have each local low point of the system equipped with means to drain the fluid.
CAUTION.
Draining and re-filling the fluid cooler must be performed by trained personnel, according to
proper field practice and system layout. Improper draining or re-filling the system could lead to equipment
damage, malfunction, premature tear and ware and may void equipment warranty.
CAUTION.
Ensuring that the fluid cooler and associated system(s) equipped with proper means of
draining, creating draining and re-filling procedures as well as determining whether draining is warranted to
protect the equipment is outside of manufacturer’s scope an d is a responsibility of installing contractor and local
maintenance team.
