This calculator is used to calculate how much refrigerant can be recovered into a recovery tank.
It's part of the HVAC-Calcs file available for IOS users, who first download FileMaker from the app store.
Email me at oilman19008@yahoo.com if you would like a copy of the file. Include 'HVAC-Calcs file' in subject line.
Many of these calculations are also available on an Excel spreadsheet. I can send you that file also.
