The Real Time Temperature Transient Program is a powerful personal computer-based software package that employs transient heat transfer analysis, allowing engineers and scientists to easily perform complex calculations and measure HVAC system performance.

RT3 was designed by engineers to reduce the time to perform nuclear plant HVAC calculations.

RT3 has already saved HGP's clients millions of dollars by better defining the margin in their HVAC design configuration.
