Dry Cooler Maintenance
Quest equipment is intended to provide the ability to perform sensible cooling year-round. As such, systems are
sold with appropriate glycol concentrations to prevent freezing/burst hazards.
Though dry cooler itself is normally equipped with means to be drained properly/fully, it is recommended to have
same means in place for entire system (dry cooler
–
piping
–
HVAC system 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 dry 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 dry 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 ou
tside of manufacturer’s scope and is a responsibility of installing contractor and local
maintenance team.
