Which step in equipment sizing comes before ordering the unit?

Performing load calculations is a crucial step in the equipment sizing process, as it provides the necessary data to determine the specifications and capacity required for the unit. This step involves analyzing the demands that the equipment will need to meet, based on the specific requirements of the facility and the tasks that will be performed. Load calculations help establish baseline requirements, ensuring that the equipment selected can adequately handle the intended loads without being over- or under-sized, which could lead to inefficiencies or even system failures.

This foundational step informs all subsequent actions, including selecting the correct equipment and checking current facility use, as it ensures that decisions are made based on accurate and relevant data. Only after having completed the load calculations can one appropriately assess available options and move forward with making an informed order for the unit.
