3.7 Refrigerant Management System
The MAC2000’s Refrigerant Management System tracks all aspects of
refrigeration usage, which can significantly help in the management
of an A/C repair business. In addition, the unit’s software allows a
business to meet new federal regulations requiring strict records of
refrigerant usage.
Refrigerant measurement during charging is extremely accurate. In
the recovery mode, however, accuracy is plus or minus 3 ounces based
on variations in air temperature and pressure.
Uses of the refrigerant data include:
• Improved record keeping
• Accurate determination of net profits for your business
• Reduced billing errors
• Minimized refrigerant loss from leaks and theft
• Reduced technician errors
