PT Chart

Honeywell International, Inc.

About this app

HVAC mechanics have a new option when it comes to the standard paper pressure-temperature (PT) chart they currently carry. Honeywell offers a colorful display in which users can select a refrigerant and get all of the data they need to perform their tasks in the field. Using the touch screen, users can quickly calculate superheat and subcool averages to set a control.

Ratings and reviews

Latest release fixes all of the previous versions issues. Must have for techs for setting superheat, sub cooling and working with refrigerants with temperature glide

doesnt actually have the pressure temperature correlation. just average coil temp, superheat and subcooling

App is good but is not as convenient as of "Danfoss Refrigerant Slider" app.
