PHASTEx v1.01 is a modified Excel format version of The Process Heating Assessment and Survey Tool (PHAST).  It is developed by E3M Inc. in collaboration with Oak Ridge National Laboratory (ORNL).  PHASTEx software tool is designed to improve energy efficiency and save energy for industrial heating systems. Industrial heating systems include all commonly used heating equipment such as furnaces, melters, ovens, heaters, dryers, and boilers used in industrial facilities. The PHAST and PHASTEx tools have been used in many industrial plants in the U.S. and a number of other countries to identify energy use distribution, estimate energy losses, as well as analyze potential energy savings by using commonly recommended energy saving measures.

PHASTEx is specifically designed to be used where it is necessary to consider multi component charge-load and account for a number of different areas of energy losses. Use of PHASTEx requires collection of certain critical data for the heating equipment. The required data are collected when the heating equipment is operating at typical or average production conditions. A report is generated to show various areas of energy use and the amount of energy used for each of these areas. The data are reviewed to identify possible areas of large energy use. PHASTEx can be used to analyze energy savings by applying commonly used energy saving measures. Potential energy savings with application of energy saving measures are displayed using a separate column of "modified conditions".  The PHASTEx tool is a downloadable, standalone tool, and doesn’t require import and export functionalities. The users can create plant specific MS Excel files and share the results with their colleagues by sharing actual file.  

Purpose: 

Conduct an energy assessment or energy audit of the heating equipment used in an industrial plant to identify energy use distribution, estimate energy losses, as well as analyze potential energy savings by using commonly recommended energy saving measures. The tool can be used for most industrial plants in manufacturing sector.

Application Note: 

Please download PHASTEx and save the downloaded copy as a master file for future use.  Do not make changes to the master file.  Any changes made for a specific application must be saved separately to avoid any changes to the master file.
