Investment in commercial refrigeration has historically been in direct systems, due to lower capital costs, widely understood and readily available equipment and the comparative safety of synthetic refrigerants.
Secondary systems – where cooling is achieved by a smaller primary refrigeration circuit cooling a fluid circulating around the refrigerated space, have typically only been available to larger cool stores and food processors, providing higher levels of safety and reliability in cool store operation.
However, with the potential impacts of the HFC phase down, advances in technology have enabled secondary systems to become more commonplace across a variety of industries and applications to take advantage of the using less refrigerant through smaller primary refrigerant charge design.
The next generation in secondary systems – advanced secondary systems.
Through leading design and technology, the development of advanced secondary systems using natural refrigeration provides companies with a competitive advantage through superior performance and operational efficiencies, including energy use reductions and improved reliability, while ensuring safety and compliance with regulatory requirements.
