If you have read the Compressors Unlimited blog in recent years, you’ve probably seen one of our most common pieces of advice. We always warn our readers not to assume that HVAC problems are caused by the compressor and to check for trouble elsewhere before spending too much time on it.
The commercial refrigeration system has expanded to a massive industry. The process of chilling can be a high-temperature process to get the environment to low-temperature freezing. Freezers hold key importance in the food business. If the refrigerating system does not work properly, the entire business is jeopardized.
One question that you will often hear with regard to commercial compressors is how much oil pressure they need to operate. The oil pressure required will depend on the size, type and intended use of the system. The age of your compressor may also affect oil pressure, because older compressors have more worn parts, which creates gaps that allow for extra oil to flow, thereby reducing pressure in the system. As you compare different compressor types and oil pressure requirements, it is important to understand the difference between useful or net oil pressure and discharge oil pressure. These two measurements apply to different parts of your system, and you must understand which is which to ensure that your compressor is properly lubricated and operating normally.
One of the key ingredients to a well-functioning commercial compressor is having the right lubricant in place. Oil or lubricant protects your compressor, and without it, your compressor will break down quickly. The problem is that there are many different types of compressor oils and lubricants on the market, so you need to know how to choose the right type for your commercial system.
When you invest in a remanufactured commercial compressor, what you are really buying is a piece of equipment that has been restored to original manufacturer specifications. If you've shopped online for a remanufactured compressor, you've probably seen a whole range of companies offering compressors at varying prices. So how do you go about determining which ones are high quality and which ones are not? Here are a few hints to help you get the best quality remanufactured commercial compressor from a trusted source.
In an effort to keep your commercial HVAC and refrigeration systems in good shape, it is important to understand the difference between the various components. Even being able to identify individual components can help with troubleshooting and identifying problems before they grow into serious failures. In this guide, we will explore the differences between your condensing unit and your commercial compressor so that you will be able to correctly identify each piece of the puzzle and understand how they work together.
Refrigeration has been accomplished in a variety of ways over the course of history, but vapor-compression refrigeration systems (VCRS) have become the preferred option thanks to their efficiency and reliability. If you've ever driven a car or used an HVAC system, you have probably used a VCRS without even realizing it. So what is a vapor-compression refrigeration system?
Bearing vibration is an indication of parts wearing down over time. HVAC maintenance technicians use vibration tests to determine signs of wear and plan a proper maintenance course for the future. With this guide, you should be able to identify early signs of bearing vibration so you can call in an expert to run a full diagnostic test. Here's what that process looks like for you:
Commercial compressors are built for a wide range of functions and services. Oftentimes compressors are oversized for their intended application in hopes that they will last longer and take on fewer stresses with the extra headroom. However, this can also lead to challenges when it comes to maximizing the efficiency of the compressor within its operating range. This is where re-expansion gas comes into play.
A motor protection module is a key component in any healthy compressor system. Many people have never heard of a motor protection module, and have no idea how this particular component helps protect their compressors in the long run. We're here to explain the importance of this part and how it works for you.
