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