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.

Understanding the Selection of Direct Expansion (DX) Coils for Both Cooling and Heating
The need to heat without the use of onsite fossil fuels (i.e. electrifi cation of heat) has become an urgent initiative as the built environment focuses on decarbonization. Paramount to these goals is the broader use of heat pumps. But to maximize the use of mechanical heating, we must understand how to select direct expansion (DX) coils for both cooling and heating operation.
Trane Engineers Newsletter LIVE programs are technical, in-depth 60-minute programs covering the topics listed below. Many are available on-demand, free of charge for continuing education credit.
