Trane Engineers Newsletters are topical, informative articles that provide engineering professionals who design HVAC systems with reliable, objective, and technologically current information in a non-commercial format.
For 50 years, these newsletters have been published by Trane Applications Engineering group to aid engineers in the design and application of HVAC systems. Subjects range from acoustics to water piping to interpretation of ASHRAE standards. These newsletters have become a trusted technical resource, with a current circulation of more than 40,000.

A2L Refrigerants and ASHRAE® Standard 15
The HVAC&R industry is in the midst of another refrigerant transition. Some of the newer refrigerants under consideration are designated as having “lower
flammability” (Class 2L), indicating that they can ignite under certain conditions. Building codes and industry standards (such as ASHRAE Standard 15) have been updated to include safety requirements that reflect the less-flammable nature of Class 2L refrigerants.
