Don't let decisions overwhelm you when buying equipment.
A few years ago, I had a new house built. What I liked best about the process was being able to tailor the home to my wants and needs. As long as I could afford what the change would add to the contract price, I could do whatever I wanted. What sometimes overwhelmed me was all of the decisions I had to make. For example, once I'd decided on hardwood floors in some of the rooms, you'd think my job was done. But no, I still had to select the stain color, gloss of the finish, and even the direction the boards were to be laid. Multiply myriad details by the myriad choices when building a home and you'd be overwhelmed, too. At times, the choice was easy. But, when all things were equal, I still had to make a choice. How could I be sure that what I chose would work with my other choices? At those moments, I longed for a Martha Stewart-like maven who could just make it all work for me.
Process heating applications often aren't much different than my decorating dilemmas. Process engineers don't buy ovens, dryers and other heat processing equipment every day -- and even if they have purchased similar equipment in the past, that's no guarantee that their knowledge will apply when they work with a different process.
