17 The RAC Engineer’s Guide to Low GWP Refrigerants SILENSYS® Advanced condensing units The SILENSYS® range offers acoustically engineered, streamlined, fully featured and ready to install condensing units. They have exceptionally low noise levels, regardless of the installation conditions. The design means that they can be installed easily and be floor or wall mounted. All accessories are supplied as standard. The main components can be accessed immediately, ensuring easy maintenance as well as ease of installation for additional control or command components. The units are suitable for cold rooms, display cases, fermentation rooms, reach-ins, wine cellars and ice machines. Features and benefits The units offer a sustainable solution and run on low GWP refrigerants R455A, R454C and R1234yf. SILENSYS® Advanced condensing units address all requirements for stationary refrigeration systems. They are COP & SEPR compliant according to the Eco-design Directive for stationary refrigeration systems and condensing units. The units are designed to the highest safety standards and should be installed by a qualified contractor. Their design helps prevent refrigerant leaks and the units are tested on an assembly line before being sold. They are appropriate for systems with cooling capacities ranging from 1Kw to 15Kw, are suitable for direct expansion systems and are simple to install. Acoustics The compressor compartment of SILENSYS® Advanced condensing units is insulated and the fan blades benefit from optimised geometry. Compliance SILENSYS® Advanced condensing units are designed to meet standard series EN378 of systems, ISO5149 and all the directives and applicable regulations. As with all jobs in refrigeration and air conditioning, it is the responsibility of the installer to conduct a risk analysis of the system in its environment before starting work.
