Pressure-Temperature (PT) charts, suction operating bounds, safety classifications, and charging diagnostics for field HVAC technicians and plant engineers.
High-pressure near-azeotropic HFC blend (50% R-32 / 50% R-125) widely used in modern inverter split ACs.
Next-gen zero-ODP single component refrigerant with 67% lower GWP than R-410A and higher energy efficiency.
Standard medium-pressure refrigerant for domestic refrigerators, automotive AC, and centrifugal water chillers.
Heavy-duty low and medium-temperature commercial refrigeration blend for supermarket freezers and walk-in coolers.
Zeotropic HFC blend (R-32/R-125/R-134a) designed as a drop-in retrofit for legacy R-22 commercial rooftop units.
Legacy HCFC refrigerant used in older split ACs. Being phased out globally due to ozone depletion potential (ODP).
Use our field-ready PT chart tool to dynamically look up bubble/dew saturation points for R-410A, R-32, R-134a, R-404A, and R-22.
