About this title

From the author:

Information in this book is based on my thirty years of technical field experience with process control instrumentation and the generation and utilization of steam. This practical and technical knowledge in both areas was acquired from leaders in the food, refining, petrochemical and other industries who have helped me successfully pinpoint and solve chronic, costly process problems for their companies.

My background in the function and application of steam traps has provided the know-how to solve problems, such as those caused by unchecked and misapplied traps. Sometimes, simple changes produce quick paybacks and a safer environment. But, my job is more than handling trap difficulties. It is to educate and help customers make wise energy-saving decisions. The prime goal is not to produce short-term fixes, rather practical solutions that improve processes and reduce maintenance, usage of fuel, chemicals and water.


"... very informative and useful source of information... has helped us identify and correct a number of energy opportunities in the field. I recommend this book for all who are involved with steam systems."

Bernie Shepard, Sr. Director Engineering, Pilgrim's Pride Corp.

"Straightforward, basic info with historical insight. Great job!"

Dale Leckie, Assets Specialist, Water Treatment, Suncor Energy

"Thanks for the books, they are a great guide - nicely done."

Mark Robertson, Reliability Specialist, Land O' Lakes

"Got your books and found them very to the point. No 'fluff' - just straightforward explanations... good to see the insulation savings chart. Curious what the savings are for fiberglass insulation with PVC jacketing. Enjoyed your book and will make it available here to anyone interested."

Tony Meier, Maintenance Lead, Cargil (Horizon Milling)

"Read your book. I must say it was jam-packed with useful information. Very well done."

Brian Navlyt, Maintenance, Purina Animal Nutrition LLC

"Awesome job, well done."

Tim Farmer, Feed Mill Supervisor, Tyson Foods, Inc.

"Bill, the books are a big hit! I may be asking for a few more in the future if they're available."

Dwayne Bagley, Maintenance Team Leader, CSM Bakery Products
