Retrofit Your Industrial Refrigeration System

If you have an old refrigeration system that is constantly needing repairs, consider contacting our refrigeration engineers to retrofit your old system with modern technologies. Discovery Designs Refrigeration specializes in retrofitting industrial refrigeration systems to be more energy-efficient and save money.

Upgrade Your Refrigeration System to CO2 (R-744) or Ammonia (R-717)

Recently, laws and regulations have limited the use of environmentally adverse refrigerants like HFC-134a (known as R-134a). The previous generation of refrigeration technology has a high Global Warming Potentials (GWP) and Ozone Depletion Potential (ODP). CO2 and ammonia refrigerants are the top preferred alternatives today. CO2 is preferred for large commercial systems (like the ones typically found in supermarkets and food distributors) because they have fewer risks than ammonia refrigerants and are more cost-effective for larger systems. CO2 is now recognized by scientists as the best natural refrigerant for food retail markets. CO2 is increasingly being used in smaller systems too.

Retrofit Refrigerant Compatibility

The first step to retrofit your industrial refrigeration system is to make sure the new components will be compatible with your current system. Our refrigeration professionals can help assess your system's compatibility. We look at 9 components:

  • Compressors - the heart of the system that forces the refrigerant to move around between all the major components
  • Coils - the evaporator coils help maintain the cool temperature inside a refrigeration unit by absorbing warm air that passes through them
  • Heat exchanger - the component that ejects unwanted heat and pulls in cool air
  • Cooling tower - the part that expels waste heat out of the system
  • Relief valves - these valves prevent pressure from excess heat from building up
  • Pumps - the component that moves the refrigerant through the entire system
  • Lubrication oil - the oil and oil filters will need to be compatible with the compressor
  • Pipework - the existing piping system will need to be assessed by a professional to determine if a different density and enthalpy will result in different velocities or pressure dropping
  • Controller - the controller may need to be changed depending on the refrigerant and system 

Cons of Retrofitting Refrigeration Systems

The main downside to retrofitting a commercial refrigeration unit is retrofitting will likely compromise on system performance and efficiency. The system was originally designed to handle a different type of refrigerant. Installing a new refrigeration system will result in higher efficiency and save money in the long run. However, our engineers understand that installing a new system may not be financially viable, which is why we offer retrofitting services. Retrofitting a system is the least expensive way to comply will new laws and regulations. 


With over 20 years of experience in cold storage, process piping installation, fabrication, systems engineering and project management, you can rest assured our engineers are ready for any complication.
