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.

Bearings are designed to help the internal components of your compressor glide smoothly around one another without binding. Unfortunately, bearings are a wearable part, and as they get worn down there are gaps in their path which can cause vibration. Knowing the common signs of vibration and bearing wear is a good way to plan for replacements before something goes wrong. 

Trane has always been a leader in the commercial compressor industry, since its earliest days, but modern Trane compressors are going a step above and beyond to give consumers and businesses alike an unbeatable experience.  There is nowhere where this is quite as apparent as it is in Trane's commercial compressor units, including everything from their reciprocating compressors to their scroll and screw designs. 

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? 

Compressor floodback is a common cause of HVAC/R system failure. Floodback occurs when uncontrolled liquid refrigerant enters the compressor during system operation. In an HVAC/R system, the refrigerant exits the evaporator and enters the compressor in a vapor state. But when the refrigerant is not vaporized entirely in the evaporator, a part of it gets sucked into the compressor in its liquid form. Compressor floodback may be misdiagnosed as compressor failure, even though the compressor doesn’t cause this phenomenon.

Labs are common in different industry sectors, including scientific research and manufacturing. However, strict temperature and humidity control is required particularly in medical and pharmaceutical laboratories. A lab’s environment together with storage and testing areas need to be maintained at certain temperature and humidity levels in order to ensure the safety and quality of different samples and lab products.       

When assessing the efficiency of an HVAC/R system, all operating expenses should be considered, including the cost of energy consumption, maintenance, repairs, and eventually equipment replacement. Although a variety of factors can affect the efficiency of HVAC and refrigeration systems, the compressor plays a major role in the overall performance of these systems. The consequences of using an underperforming compressor can be multi-faceted and damaging to your company’s bottom line. By reading the rest of this post, you’ll find out how an inefficient compressor can decrease your profit margin.  

When it comes to commercial compressors, an undercharge or overcharge of refrigerant may have many undesirable consequences. That’s because both conditions prevent the compressor from operating at peak performance, eventually leaving you with a malfunctioning system that can negatively affect your business.

Troubleshooting undercharge and overcharge conditions for commercial compressors requires a thorough knowledge of HVAC/R systems and their functions. However, the ability to correctly identify the symptoms of an undercharged or overcharged system is key to determining and fixing the exact cause of system malfunction before it escalates into a more serious problem.

Copeland's 3D series of compressors has been one of the most successful commercial refrigeration products ever released. These powerful compressors delivered a ton of flexibility and utility to the user, while also coming with an industry leading warranty program that kept them in play for many years. Today, we still see exceptional levels of demand for Copeland 3D series compressors on the remanufactured side of things. Here's why our remanufactured Copeland 3D compressors continue to set the pace for the entire commercial refrigeration industry.
