Chemworld NexFrost HD Propylene Glycol Drum
Chemworld NexFrost HD is an industrial-grade, inhibited propylene glycol heat transfer fluid formulated for closed-loop heating and cooling systems that demand consistent thermal performance, corrosion protection, and extended service life.
Supplied as a concentrate in a 55 gallon drum, Chemworld NexFrost HD is ideal for larger system fills, maintenance programs, and contractor or facility operations managing multiple loops or high fluid volumes.
Key Performance Characteristics
- Inhibited propylene glycol formulation for closed-loop systems
- Corrosion protection for common system metals
- Supports cast iron, carbon steel, copper, and brass up to 325°F
- Compatible with aluminum components up to 190°F
- Corrosion performance aligned with ASTM D1384 (ASTM D3306 limits)
- Dyed fluid for system identification and leak detection
- Non-hazardous and non-regulated for transport
Typical Industrial Applications
- Commercial and industrial HVAC chilled water and heating loops
- Snow-melt systems, ramps, and runways
- Ice rinks and refrigeration brine circuits
- Solar thermal heat transfer systems
- Process cooling and industrial heat exchangers
Dilution Guidelines
Chemworld NexFrost HD is supplied as a concentrate and must be diluted with water prior to use. Typical operating concentrations range from 20% to 60% by volume, depending on required freeze protection.
A 50% solution provides freeze protection to approximately -25°F (-32°C). Final concentration should be verified using a refractometer.
Storage & Handling
- Store away from strong acids
- Unlined carbon steel drums are suitable for normal storage cycles
- For long-term storage of concentrate (>12 months), stainless steel, aluminum, or lined carbon steel drums are recommended

Questions & Answers
What is the advantage of the 55 gallon drum size?
The 55 gallon drum is well suited for large systems, multi-loop facilities, and ongoing maintenance programs where higher fluid volumes are required.
Is Chemworld NexFrost HD supplied as a premixed solution?
No. Chemworld NexFrost HD is supplied as a concentrate and must be diluted with water prior to use based on the desired freeze protection level.
What concentration should I use?
Typical operating concentrations range from 20%–60% by volume. A 50% solution provides freeze protection to approximately -25°F (-32°C). Always verify concentration with a refractometer.
Does Chemworld NexFrost HD help control corrosion?
Yes. Chemworld NexFrost HD contains a corrosion inhibitor package designed to protect common system metals including steel, cast iron, copper alloys, and aluminum within specified temperature limits.
Is this product suitable for food-related systems?
For applications where incidental food contact is required, the Chemworld NexFrost (non-HD) product line is recommended. Chemworld NexFrost HD is intended for industrial heat transfer performance.
Is this product regulated for shipping?
Chemworld NexFrost HD is not regulated as dangerous goods for domestic or international transportation.
