Back in 1999, there were global calls for recognition of climate change as a serious problem facing the next several generations. Companies across all sectors were called upon to investigate ways to reduce waste and cut carbon emissions. Hitachi, as one of the world's leading manufacturers of industrial equipment, rose to the occasion and rolled out their own program for saving energy and improving operations for all of their customers. This program resulted in many improvements in commercial compressor installations and offered companies a clear path to operating more efficiently in the future. We'll take a look at how we got there. 

How hard is it to spot a new commercial compressor versus an old one? The answer is, it really depends on what you're looking at. For many people, identifying the age and quality of a particular compressor is nearly impossible, because it all comes down to the components inside. Today, there are three main categories of commercial compressors available for sale: new, rebuilt and remanufactured. Knowing the difference between these three products will determine how good of a deal you get on your next buy.

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. 

Today’s compressor models and technologies are as varied as the HVAC/R applications they need to serve. But when it comes to the reliability and performance of HVAC/R systems, the scroll compressor delivers one of the best options for specific residential, commercial and industrial applications. That’s because modern scroll compressors are equipped with new technologies that allow compressors to deliver higher efficiency and greater flexibility under full- and part-load conditions.

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.

The term Rotary Compressors can actually be used to describe several different types of compressor mechanisms. The one thing they have in common is that the air inside is being compressed through the rotating action of some internal component. The way the insides of the compressor look actually breaks down even further. Here are the most common types of commercial rotary compressors in use today:

For decades, HVAC systems have been equipped with conventional single-speed compressors. An HVAC system that uses a single-speed compressor switches on when the indoor temperature reaches a certain value. The compressor will continue to operate at full capacity until the indoor temperature decreases sufficiently. When the temperature matches the thermostat setting, the compressor turns off.

Rotary screw compressors are commonly used in a wide range of commercial, industrial, and light manufacturing applications that range from 3hp to over 500hp. A conventional rotary screw compressor employs two intermeshing rotors in a stator housing that has an intake and a discharge port. Also referred to as helical screws, the rotors interlock precisely and spin at high speeds, in opposite directions.

Over the past few years, compressor manufacturers have worked to develop modulation technologies that not only provide better system performance, higher efficiency, and improved comfort but also meet specific part- and full-load challenges.  

In recent years, the cooling loads in residential, commercial and public buildings have grown constantly due to a series of environmental and lifestyle changes. In response, compressor manufacturers have developed new technologies that can meet different cooling demands in a sustainable manner.
