Diversitech PG-100-01 Propylene Glycol 1 Gallon

Product Description

The DIVERSITECH PG-100-01 is a propylene glycol-based freeze protection and corrosion inhibitor formulated for use in closed-loop hydronic, HVAC, and plumbing piping systems. This 1-gallon product is designed to prevent freeze damage in water-based systems during cold-weather operation or seasonal shutdowns. The inhibitor package helps protect ferrous and non-ferrous metals from corrosion and scale buildup inside piping, coils, and heat exchangers. HVAC technicians and licensed plumbers install this product in systems where prolonged exposure to below-freezing temperatures presents a risk to piping integrity and equipment performance.

This glycol solution is suited for residential and light commercial applications including hydronic heating systems, chilled water loops, radiant floor systems, and domestic water piping in unheated spaces. It is commonly used during pre-season winterization of HVAC equipment and plumbing runs in crawl spaces, attics, and exterior wall cavities where freeze risk is elevated. The product ships as a ready-to-dilute or direct-use concentrate depending on system requirements and desired freeze protection level.

Key Features

• Propylene glycol base provides freeze protection in closed-loop and open piping systems
• Corrosion inhibitor package helps protect ferrous and non-ferrous metal components
• 1-gallon container sized for single-system service calls or top-off applications
• Suitable for hydronic heating, chilled water, and radiant floor system applications
• Propylene glycol formulation is lower toxicity compared to ethylene glycol alternatives

Compatibility

Designed as an OEM-style freeze protection solution for use in residential and light commercial closed-loop hydronic, HVAC, and plumbing piping systems where propylene glycol inhibitor treatment is specified.

Installation Notes

Installation and system treatment should be performed by a licensed HVAC technician or plumber familiar with hydronic or plumbing system service procedures. Prior to adding glycol solution, isolate and depressurize the system section being treated and verify that all existing fluid has been drained or flushed as required. Follow the system manufacturer and local code requirements for glycol concentration ratios appropriate to the minimum expected ambient temperature. Dispose of drained system fluid in accordance with local environmental regulations.
