Three system-cleaning products are designed for use in thermal-fluid heaters and systems. These products fit into two product types, based on how they are used. The first is as an additive cleaner, where the user adds the cleaner as 5 to 10 percent of the system volume to clean a system while it runs. The second is as an off-line cleaner, where the user shuts system down; drains the fluid; fills with cleaner; circulates; drains; flushes; recharges and resumes operations.
