Industrial refrigeration units are not the same as residential refrigeration units. When it comes to cooling food items at an industrial level, different refrigerants are used, including anhydrous ammonia, carbon dioxide, and propane. In order to choose the best refrigeration system for your industrial space, it's best to first understand how each unit functions.
Anhydrous ammonia is used frequently, and it is often the type of coolant in most industrial refrigeration units. Due to ammonia's excellent heat transfer capabilities, this coolant can keep food cold for a long period of time. In addition, ammonia does not harm the environment, and it is also biodegradable.
Carbon dioxide was once the only form of industrial refrigeration. Even though carbon dioxide was largely phased out over the past few years, this type of coolant is resurfacing once again. The main advantage to carbon dioxide is that it can cool foods quickly, which is often crucial for industrial applications.
Propane refrigeration units tend to be found mostly in refineries. Since propane is highly flammable, this type of refrigeration system must be carefully observed. In fact, most countries do not allow the use of propane within a regular industrial setting. Propane refrigeration units can be used in industrial areas that follow specific laws in regards to safety.
