ANTIFREEZE VERIFICATION
Both Glycol and Alcohol based antifreeze solutions can
be veried to the specic percentage of volume within the
ground loop system. One of the easiest ways to check this
is through use of a Hydrometer to check the specic density
of the ground loop uid and comparing these to the charts
supplied by the antifreeze manufacturer (see Figure 11).
Hydrometers can be purchased from your local distributor
and are also available through national wholesalers.

WARNING
Always use properly marked vehicles (D.O.T.
placards) and clean/suitable/properly marked
identified containers for handling flammable
antifreeze mixtures. Post and advise those
on the jobsite of chemical use and potential
dangers of handling and storage.
CAUTION
Always obtain MSDS (material safety data
sheets) for all chemicals used in ground loop
applications - including chemicals used as
antifreeze.

It is recommended that IGSHPA design and specifications are utilized for Loop Design, Pipe Manifolding and Hot Fusion
operations.
There are many available software programs available to aid with loop design parameters. Your local loop material or
equipment supplier may have this technology available. Technical Service has the capability to assist you in this area as well,
but it is on a first come - first serve basis.
