Accurately Estimate the Amount a System Needs

Access the Calculator

freezemaster™ antifreeze meets NFPA 25 standards, is approved by UL for use in more applications than any other and is the only UL-listed antifreeze for use in volumes up to 375 gallons in Ordinary Hazard Groups 1 & 2.

Beyond ensuring an antifreeze product is listed, it is also critical to ensure approval specific to your application and system volume. Our volume calculator accurately estimates the amount of freezemaster™ antifreeze you will need for a given system.

How the Calculator Works

  1. Select your piping material type – this is essential because different materials have different internal dimensions, which are required for proper volume calculation.
  2. Enter the size and length of pipe.
  3. Enter the number of drops.
