Things to Know about Anhydrous Ammonia Refrigeration Systems

When you have commercial or industrial refrigeration needs, you may want to check out the benefits of anhydrous ammonia refrigeration systems. If your equipment uses NH3 (ammonia), it’s a good idea to know how these systems run and what to do if you have problems. Here is some basic information on NH3.

What is Anhydrous Ammonia?

Ammonia consists of hydrogen and nitrogen. For every one atom of nitrogen, it has three atoms of hydrogen. Its chemical name is NH3, and it emits toxic fumes.

Anhydrous means it has no dissolved water, so it’s pure. Anhydrous NH3 is not the same as household cleaning ammonia because those cleaners have water. Pure liquid NH3 boils easily. In fact, its boiling point is about minus 28 degrees Fahrenheit. This makes it an efficient refrigerant, and that’s one reason why it’s used for anhydrous ammonia refrigeration.

Toxicity

One must exercise caution around NH3 equipment because the fumes can cause harm when inhaled. This is why you need special safety precautions and equipment for NH3 refrigeration systems. However, because fumes are easily detected, you can tell when there are leaks in the system without special equipment.

Cost-effective

NH3 systems are the most cost-effective option for large cooling and chilling needs. In fact, they are between ten and twenty percent more efficient than halocarbon cooling systems.

Better in Colder Systems

Do you need to freeze products or keep things extremely cold? If so, you should consider anhydrous ammonia refrigeration equipment. It takes more energy to keep things below zero degrees Fahrenheit, so you’ll save even more money on energy with NH3 systems.

State and Local Regulations

Companies with NH3 systems must meet stringent rules set by the EPA and OSHA. The best way to make sure you meet all qualifications is to hire a trusted refrigeration company specializing in ammonia systems. They can handle all your needs.
