Safe and Reliable

HFOs have been heavily studied and are rigorously regulated, pursuant the U.S. Clean Air Act, other U.S. EPA programs including TSCA and FIFRA, and California CARB. To-date, more than 75 third party studies, including Good Laboratory Practice-compliant OECD in vitro, acute and chronic toxicology reports, and environmental properties research that evaluates persistence and global warming potential, have been conducted on HFOs to ensure they are non-PBT (non-persistent, non-bioaccumulate, and non-toxic) and safe for human and environmental health. These oversight agencies rely upon the best, most accurate testing methods available, and have consistently listed HFOs as acceptable and sustainable alternatives to other less climate-friendly substances.  

Higher level of safety compared with other industrial refrigerants such as CO2, ammonia and propane.

  • Honeywell HFOs are non-persistent, non-bioaccumulate, and non-toxic
  • HFOs are non-flammable or mildly flammable, unlike hydrocarbons such as propane
  • HFOs can be used in low pressure systems which reduces the potential for pressure explosions, and catastrophic equipment failure
  • HFOs operate at lower pressures which, in most cases, avoids complete shutdown of equipment
  • HFOs maintain performance over the lifetime of the equipment which increases the usable life of the system and reduces maintenance needs
  • HFO installations have more trained technicians for service needs
  • HFOs provide a more reliable heat supply through less downtime
