Mixing & Freeze Protection Guidance
Chemworld NexFrost HD is supplied as a concentrate and should be diluted with water to meet system requirements. Typical working concentrations are 20%–60% by volume.
A 50% solution provides freeze protection to approximately -25°F (-32°C). Verify final concentration using a refractometer and follow equipment manufacturer recommendations.
Storage & Compatibility Notes
- Store away from strong acids
- Unlined carbon steel drums are acceptable for normal storage cycles
- For concentrate storage beyond 12 months, stainless steel, aluminum, or lined carbon steel containers are recommended (vinyl, epoxy, or phenolic linings)

Questions & Answers
What is included in the full pallet option?
The full pallet includes 4 × 55 gallon drums of Chemworld NexFrost HD concentrate, for a total of 220 gallons.
Is this product ready to use out of the drum?
Chemworld NexFrost HD is supplied as a concentrate and must be diluted with water before use. Typical operating concentrations range from 30%–60% by volume depending on freeze protection requirements.
What freeze protection does a 50% mix provide?
A 50% solution provides freeze protection to approximately -25°F (-32°C). Confirm final concentration with a refractometer after mixing.
What systems commonly use Chemworld NexFrost HD?
Chemworld NexFrost HD is commonly used in closed-loop HVAC systems, snow-melt systems, ice rinks, solar thermal installations, and industrial process cooling applications.
Does Chemworld NexFrost HD provide corrosion protection?
Yes. Chemworld NexFrost HD contains a corrosion inhibitor package designed to protect common system metals. It supports cast iron, carbon steel, copper, and brass components up to 325°F and aluminum components up to 190°F.
Is Chemworld NexFrost HD appropriate where incidental food contact is required?
For applications requiring incidental food-contact considerations, use the Chemworld NexFrost (non-HD) product line. Chemworld NexFrost HD is intended for industrial heat transfer service.
How should I store the pallet if not used immediately?
Store the drums away from strong acids. Unlined carbon steel drums are suitable for normal storage. If storing concentrate longer than 12 months, stainless steel, aluminum, or lined carbon steel containers are recommended.
Lead time 24-48 hours.
