There are many possible causes of oxygen
contamination such as:
1. Addition of excessive make-up water as a result of
system leaks.
2. Absorption through open tanks and fittings.
3. Oxygen permeable materials in the distribution
system.
In order to insure long product life, oxygen sources
should be eliminated. This can be accomplished by
taking the following measures:
FIG. 17
RECOMMENDED BOILER PIPING FOR
COMBINATION HEATING & COOLING SYSTEMS
1. Repairing system leaks to eliminate the need for
addition of make-up water.
2. Eliminating open tanks from the system.
3. Eliminating and/or repairing fittings which allow
oxygen absorption.
4. Use of non-permeable materials in the distribution
system.
5. Isolating the boiler from the system water by
installing a heat exchanger.
