Units:
Allows the user to specify the units of measure that will be used to specify input and output parameters. The Expansion Tank Selection Program offers the options of either U.S. (English) or SI (System International) units.

Fluid Type:
Clicking on the Fluid Type Drop Down Menu will allow the User to make Expansion Tank Selections based on the Fluid Types.

Pipe Material:
Clicking on the Pipe Material Drop Down Menu will allow the User to specify either Copper or Steel Pipe for the system being sized.

System Volume (gal):
Enter the total volume of fluid in the system. The total system volume should include the amount of fluid in the piping system (including all valves and fittings) as well as in the pumps and other equipment in the system.

Minimum of Initial Fill or Operating Temperature (°F):
Enter the minimum of either the initial fill temperature or the minimum expected operating temperature. This temperature will be used to establish the lower level of the operating range for which the expansion of the system fluid is calculated. As such, it should be the lowest temperature that the system will ever be expected to see. For example, in a heating system, the minimum temperature will probably be the temperature of the water when the system is filled (approximately 50-55°F). In a chilled water system, the minimum temperature will probably be experienced while the system is operating and will be equal to the design temperature leaving the chiller. The allowable range for this value is 40.0 to 240.0 °F.

Maximum Design Temperature (°F):
Enter the maximum expected system temperature. This temperature will be used to establish the highest level of the operating range for which the expansion of the system fluid is calculated. As such, it should be the highest temperature that the system will ever be expected to see. For example, in a heating system, the maximum temperature will probably be the temperature of the water leaving the heat source (boiler). In a chilled water system, the maximum temperature will probably be experienced on a hot summer day when the system is down for maintenance and the ambient temperature causes the system fluid temperature to rise. The allowable range for this value is 40.0 to 240.0 °F.

Minimum of Initial Fill or Operating Pressure (psig):
Enter the minimum of either the initial fill pressure or the system operating pressure. The allowable range for this value is 0.0 to 250.0 psig).

Maximum Design Pressure (psig):
Enter the maximum expected system pressure. The allowable range for this value is 0.0 to 250.0 psig.
