Quick Summary

  • Industry-Leading Capacity: Holds up to 24 Standard HotPacs (10" x 12") for maximum clinical throughput.
  • Superior Mobility: Heavy-duty 3" swivel-type rubber casters ensure silent, friction-free movement between treatment bays.
  • Maximum Efficiency: Full fiberglass insulation reduces energy consumption and prevents heat loss in large spaces.

Why Choose the Chattanooga M-4 Mobile Unit?

The Chattanooga M-4 is the ultimate solution for high-demand clinical workflows. In environments where dozens of patients require thermal therapy daily, smaller units often struggle to reheat fast enough. The M-4 eliminates this bottleneck with its massive 27-gallon reservoir, ensuring a fully heated bentonite clay pack is always ready the moment you need it.

Built from high-quality, corrosion-resistant stainless steel, the M-4 is designed for decades of clinical service. Despite its large capacity, it is engineered with a compact footprint, requiring only 20" x 32" of floor space. The fiberglass-insulated walls keep the internal water between 160°F and 165°F while ensuring the exterior remains safe for staff and patients to be near.

The unit is fully self-contained, meaning it does not require a dedicated water line or drain hookup. Its "plug-and-play" 110-120V operation makes it easy to integrate into any existing facility. For over 70 years, the M-4 has been the gold standard for treating chronic pain, arthritis, and muscle spasms in the world's leading medical institutions.

Frequently Asked Questions (FAQ)

How long does the M-4 take to reach therapeutic temperature?

Due to its large 27-gallon capacity, the M-4 takes approximately 8 hours to reach 160°F from a cold start. For this reason, most facilities choose to leave the unit on 24/7 to maintain immediate readiness.

What comes included with the M-4 unit?

The M-4 unit comes complete with an internal rack and 24 Standard Size (10" x 12") Hydrocollator Moist Heat HotPacs, providing everything you need to begin treatments out of the box.

While the unit weighs approximately 340 lbs when full, the high-quality 3" swivel casters are specifically designed to distribute that weight for smooth, one-person maneuverability on flat clinical flooring.

Fascinating exploration of God's Word!
Urban Legends of the New Testament: 40 Common Misperceptions is an impressive work by David A. Croteau that discusses 40 "commonly circulated myths, repeated throughout the culture as common knowledge, but which isn't true." But we're talking about the infallible Word of God, right? That is correct. But according to the author, certain passages of the New Testament have become victims of the notorious Urban Legend phenomena. The titles of each chapter are the actual legends and are presented as if the author really believes what he is writing to be true. The reader will soon find out that is not the case. Croteau goes on to discuss the incorrect interpretation versus an accurate interpretation and then ends the chapter with his opinion of what the text means, followed by a practical application section. The presentation and discussion of each myth is clear, although some are harder to piece through than others. The length of the chapters vary according to the history of the myth and depth of the discussion. Topics vary from the birth, life, and crucifixion of Jesus to Paul's profession, the plan of salvation, hell, divorce, money, pastors and their families, and cults. You can pick up the book and read only the chapters that interest you, although I do encourage you to read the introduction and epilogue. The prologue discusses two types of legends: a mistaken-contains wrong information; misleading-those that need clarification. The cause and solution for urban legends of the New Testament come down to three components: Context, Greek, and Backgrounds. Croteau clearly discusses this at the end of the book and my only criticism is that I would have liked that information in the introduction. I believe it would have aided in my overall structure for comprehension. Overall, the research was fascinating and I learned—a lot. This quote from the final conclusion summarizes the purpose of this book: "In the end our goal should be to interpret Scripture as accurately as possible, to apply that interpretation to our own lives, and to be transformed by God's Word so that our lives may bring glory to the One who rescued us from an eternal destiny in hell." I highly recommend this book to all readers. Don't plan to read it in one sitting. Use it as a study guide and tool to inspire you to dig deeper into God's Word.

Only Orthodoxy Will Lead to Orthopraxy and Orthopathy
Format: Kindle
This book authored by David Croteau is truly an enjoyable yet at the same time a convicting read. Even though it was written about 10 years ago, the principles of interpretation advocated by him to deal with the "mistaken and misleading legends" are timeless. Out of the 40 legends, I have encountered at least half of them in the local church, writings and even seminary especially issues pertaining to salvation, Christian living and women's adornment. The main takeaway is this: Just as there are three things that matter in property: "Location, Location, Location", similarly the three main things that matter in interpretation of the Word is: "Context, Greek, and Background Information", or even simpler: "Context, Context, Context". David Croteau has demonstrated in his 40 legends the utmost importance of context in correctly interpreting a particular passage which was unfortunately taken out of context. The interpretation can further be handled even more accurately by taking into account the Greek language and the socio-historical background behind the text. In fact, I have been focusing on these three elements in my hermeneutical approach whenever I come across passages which I need more understanding. I don't know Greek; but with the many useful online Greek tools nowadays, I can always do a word study which more or less balances my lacking of Greek knowledge. Also, the study of socio-historical background is extremely illuminating if one have access to these resources. Personally, I discover that a proper understanding of background information can eliminate most of the mistaken or misleading interpretation of a text. Lastly, I totally agree with David Croteau's conclusion: "In the end our goal should be to interpret Scripture as accurately as possible, to apply that interpretation to our own lives, and to be transformed by God’s Word so that our lives may bring glory to the One who rescued us from an eternal destiny in hell." His conclusion reminds me of a phrase which I encountered years ago: "Orthodoxy Will Lead to Orthopraxy and Orthopathy." Indeed, only by "accurately handling the word of truth" (2 Tim 2:15) can we realise the necessity of holy living and the proper response that we should have towards our living God.

The book is also great in pointing to additional resources for further study
Format: Paperback
Other than the Bible, I hesitate to use the term "must read" for a book. This one is definitely a "should read" for anyone who teaches, preaches, or wants to minister more faithfully. The book is engaging, and offers both a negative (doesn't mean this) and positive (means this) response to common urban legends of the NT. You'll be surprised by some beliefs you had that you didn't even realize were not correct, or should be adjusted. The book is also great in pointing to additional resources for further study. Pastors, seminarians, and lay people will all benefit from this book.

Rescuing the Bible from its Friends
The inerrant, infallible Word of God has endured countless intentional assaults of misrepresentation by its enemies. Unfortunately it has also had to endure the unintentional insults of misinterpretation by its friends. Dr. Croteau has given us an excellent handbook to gently correct. His specific examples are well considered and his general principles are well established. Highly recommended.

Thoughtful, Encouraging, Didactic and Accessible
The title is what drew me to the book, and then the shortness of the chapters convinced me to take up this book and read it. I've read various types of theology books, but this one addresses underlying viewpoints that the average Christian assumes. While addressing these legends, the author does a wonderful job helping the reader grow in his or her biblical interpretational skills. And the author does this in a way that is both gracious and easy to understand. Even if a reader may not agree with every conclusion, I heartily recommend this book, not only for the legends it addresses, but for the opportunity to learn how to interpret the Bible.
