FAQ

Are the So-Low Explosion Proof Manual Defrost Freezers also suitable for flammable material storage?

Yes, they are.

 

What safety designs make this unit suitable for use in a Class 1, Division II, Group C & D environment?

The unit is spark-proof, meaning that all spark generating electrical components and connections (compressor, thermostat) are isolated and sealed in vapor-proof enclosures such that they will not ignite any flammable / explosive vapors unless they are damaged. This is also why the unit must be hard-wired and the unit does not come with a power cord: standard electrical outlets carry a risk of sparking and, therefore, ignition of vapors.

 

Are there special installation considerations for an explosion-proof freezer?

Yes. The freezer must be hardwired to the building's electric and cannot be connected to an electrical outlet via a plug, as that carries a sparking risk. Furthermore, the room / area around the freezer must also be explosion proof. For instance, any nearby equipment also must be explosion proof, any lighting and / or other fixtures must be explosion-proof, and there cannot be any electrical outlets.

 

What is the weight limit on the shelves?

Each shelf has a weight limit of 50 pounds.

 

Can the shelves be removed or can the freezer be built without shelves in it?

No. The fixed shelves are permanently in place and cannot be moved nor can the unit be built without the shelves, as refrigerant lines run through the shelves to help ensure more even temperature throughout the chamber.

 

What kind of refrigerant is used in the So-Low Explosion Proof Defrost Freezers?

R-404A

ProTip

The So-Low Explosion Proof Manual Defrost Freezers are identical to the American Biotech Supply Hazardous Location Freezers, which are less expensive. They are literally the same freezers, with the same warranty and certifications. Just get the cheaper ones.

Good Stuff!
Format: Paperback
Very good material for anyone considering marriage and even couples that are already married. However, it would be best to study this book prior to being married. Dr. Chapman has been providing quality material for many years. I started utilizing his material as an aid in counseling when it was on VHS. Like I said, he's been around. While this book is not an end all be all, it definitely has some great advice and insight within its pages. It works very well in conjunction with "The 5 love languages" and "The 5 languages of apology", also offered by Dr. Chapman. There are free online quizzes and other info that can also be utilized as mentioned in the book that will enrich everything else he discusses in the book. There are several applicable true to life stories inside that help you understand each point he is attempting to relay and makes for an easy read by keeping interest up. I also ordered the audio version and found it easier to listen to and take notes for self enrichment, as well as notes for guiding others into what I hope will be lasting marriages.

Great book!
Format: Paperback
Wonderful, helpful, insightful. Points out many of the key "sore spots" that can sour a marriage if left unmanaged, and how to address them. Very helpful, whether as a premarital counseling book, a book for the happily married couple, or even for the unhappily married couple willing to set their relationship right. Must read!

Good discussion book to eliminate conflict between couples
Format: Kindle
Use this book as a checklist of things you should discuss with your partner - especially if you're considering or are in a long-term relationship. It explains each topic, why it's a likely source of conflict, how to prevent the conflicts, and includes questions for discussion between partners. Understanding and discussing these topics may not feel romantic and fun, and some of the conversations may be challenging for couples who aren't accustomed to such discussions. Do it anyway though because it will eliminate future conflicts before the conflicts even begin and make your relationship run smoother, last longer, and be a source of relaxation and contentment for you both. I'm speaking from experience here. If you are new to the study of this topic, this book will be extremely valuable for you. If you've already studied interpersonal relationships, preemptive conflict resolution, and collaborative negotiation tactics, it's still a great checklist of topics to discuss with your partner. I'm on this end of the spectrum, hence 4 of 5 stars because I'm familiar with the author's other work and this book didn't contain much new content. As a compact, all-in-one, relationship discussion guide though, it's great and worth reading and having on hand for future reference for new relationships or for when new conflicts crop up.
