Why Purity & Certification Matter

Refrigerant purity has a direct effect on system performance and equipment life. Non-condensable gases, moisture, or residue in a charge can raise head pressure, reduce cooling capacity, and shorten compressor life. Buying a factory-sealed, virgin charge – rather than reclaimed or repackaged product of unknown origin – is the simplest way to protect the equipment you're servicing.

Frequently Asked Questions

• Is this a drop-in replacement for another refrigerant?
  R-507 is a standalone azeotropic blend – confirm system compatibility before charging.
• What does the A1 safety classification mean?
  It's a refrigerant industry safety rating. This product is classified A1 (non-flammable), which describes its flammability under ASHRAE/ISO guidelines and determines what handling and installation precautions apply.
• Can this be shipped, and how should it be stored?
  Refrigerants are regulated hazardous materials and generally ship via ground freight under DOT rules. Store the cylinder upright in a cool, dry, well-ventilated area out of direct sunlight, and keep it away from heat sources.
