Designed for today’s HVACR classroom, this full-color 24" x 36" Temperature–Pressure (PT) Chart provides a clear, side-by-side comparison of commonly used legacy and next-generation refrigerants. Ideal for instructional settings, labs, and training facilities, this chart helps students and technicians quickly visualize the relationship between temperature and pressure while reinforcing refrigerant characteristics and safety classifications.
The chart includes P/T data for R-22, R-410A, R-454B, and R-32, along with bubble and dew pressures, where applicable, making it a valuable reference during lessons on system charging, diagnostics, and refrigerant transitions. Integrated temperature and pressure conversion formulas support learning and reduce the need for separate reference materials.
Printed in a large, easy-to-read format, this chart is perfect for wall display in classrooms, shops, and training labs, keeping critical information visible and accessible during instruction.
