glycol being the most popular, particularly in supermarket applications, due to its non-toxic properties.
Due to the primary circuit being confined to the plant room, up to 90% less refrigerant is needed for operation of the secondary refrigeration system, enabling a significant reduction in the risk of leaks and completely eliminating the opportunity for leaks near food chillers, as the refrigerant does not leave the plant room.
There is a common misconception that
secondary refrigeration systems have a higher installed cost, due to the additional expense of the pumps and heat exchanger. However, these initial costs can be offset against other savings over the lifetime of the system. The pipework requirements are less demanding within a secondary loop solution, helping to bring down the initial set up costs. The pipe network for a DX system needs to be designed to ensure oil returns to the compressor, which is eliminated within a secondary loop as there is no need for an oil return.
Secondary refrigeration systems also boast a lower cost of operation due to the increased energy efficiency, resulting in average energy savings of 4.9% compared with DX systems. Reduced maintenance requirements also add to the operational cost savings, as a simplified pipe network, a reduced number of leaks and a more easily accessible primary circuit all combine to culminate in a reduction in maintenance costs of up to 20%. Due to the changes in pipework
requirements, secondary loop systems can be delivered as a factory-assembled unit, which can be connected easily to the pipe system on- site, offering further installation time and cost savings. However, if this option is pursued, it is important to select a pipe network that can mirror these installation savings to help meet budget and project constraints.

transferring the cooling medium around the refrigeration circuit, with single thinwall steel the most widely installed for this application. However, glycol and hycool solutions can be highly corrosive, and if a corrosion inhibitor is not added to the solution, they can begin to corrode metal materials very quickly. Due to its corrosion resistant properties, ABS pipework, such as Durapipe’s SuperFLO ABS, is increasingly being utilised as a more effective and durable solution for secondary refrigeration systems.
Its wide operational temperature range of -40°C to +60°C makes it ideal for a secondary refrigeration application, which typically operates at -15°C to -17°C. In addition to the
performance benefits, ABS can also aid the installation process; at 1/6th the weight of steel, its lightweight nature makes it easier to handle on site, while its quick and simple solvent weld jointing technique significantly reduces installation time.
Taking all these factors into consideration and when compared with single wall steel, ABS pipe offers an installed cost saving of 30%, making it a more cost effective option. With refrigeration systems being placed under scrutiny and reviewed up and down the country, the increased performance, along with the installation, maintenance and cost savings associated with a secondary refrigeration system simply cannot be overlooked.
