Torch Coolant Specifications
Note: Refer to the supplier’s most current Material Safety Data Sheet for
information regarding safety, handling, and storage of torch coolant.
The Spirit system is shipped without torch coolant in the reservoir.
Coolant
must be added before applying power to the system.
Only use approved
torch coolant solution for optimal system performance as commercially available
antifreeze contains corrosion inhibitors that will damage the cooling system. The
standard coolant solution consists of 25% industrial grade propylene glycol and
provides freezing protection down to -13º C (9º F). The standard solution can be
ordered in one-gallon containers, PN BK500695. For operating temperatures
below -13º C, a 50% solution of industrial grade propylene glycol can be ordered
in one-gallon containers, PN BK500895, providing protection down to -36º C
(-33º F).
Failure to use the proper propylene glycol
solution may result in cooling
system and/or torch damage
.
The torch coolant should be flushed out of the Spirit system every six months
and replaced with new coolant. The coolant filter / deionization cartridge should
also be changed at the same time. See Section 6 for details.
