If your application requires a unique, highly efficient, and compact cooling system, our decades of experience and leading-edge technology can help us design and manufacture a custom cooling system that meets your needs and gives you a distinct market advantage.


  • What Are The Benefits of Vapor Compression?

    The vapor compression refrigerator is known for its ability to remove large amounts of heat with a small mass flow of refrigerant. It is one of the most efficient refrigeration systems on a macro scale, with a high coefficient of performance (COP). In addition, this system is capable of achieving sub-ambient temperatures without the need for additional pumping energy at the cold junction.


    How Does a Compression Refrigeration System Work? In the compression refrigeration cycle, a liquid refrigerant is continuously circulated through a closed system consisting of four stages. As it travels through the system, the refrigerant undergoes both compression and expansion, resulting in a change in state from liquid to vapor. As this occurs, the system absorbs and releases heat, effectively lowering the temperature of the conditioned space.


    Vapor compression cooling uses the phase change of the refrigerant to efficiently cool heat sources, often to temperatures below the ambient air. This technology is commonly used in home refrigerators to keep the interior colder than the room it is in. It has been around for over a century and has been continually improved with the latest technological advances. A compressor is used to pump refrigerant from an evaporator, where it absorbs heat, to a condenser, where it releases heat. The refrigerant changes phase from liquid to vapor in the evaporator and from vapor to liquid in the condenser. This phase change, along with the compressor, makes the process very efficient.


    By using appropriate refrigerants, compressors, and heat exchangers, a vapor compression refrigeration system can provide a highly reliable and efficient means of cooling a wide range of applications, including medical equipment, laboratory equipment, high-tech lasers, military communications, and electric vehicle charging cables. At RIGID, we use only approved, environmentally safe refrigerants that comply with international regulations to reduce ozone-depleting and global warming substances. We continually monitor the evolution of international regulations and are currently testing alternative refrigerants that are even more environmentally friendly than those currently in use around the world.
