Silensys® Inverter Scroll is an advanced outdoor condensing unit designed for modern commercial refrigeration systems where operating cost reduction, low noise levels, and long-term reliability are critical business drivers. By combining proven scroll compressor technology with inverter control, it delivers a high-performance solution for cold rooms, display cases, reach‑in cabinets, and other professional refrigeration applications.

Faster installation and lower project costs

The plug & play design enables quick integration into single or multi-station systems, significantly reducing installation and commissioning time. A clean and accessible internal layout simplifies servicing, minimizes downtime, and lowers total cost of ownership—key benefits for both contractors and end users.

   

Optimized efficiency where systems actually operate

Commercial refrigeration systems rarely run at full load for extended periods. Silensys® Inverter Scroll is technically optimized for stable operation at around 30% RPM, the range where systems operate most of the year. The combination of inverter control and by‑pass regulation provides:

  • up to 20% energy savings compared to conventional solutions,
  • higher annual COP and reduced electricity costs,
  • lower mechanical and thermal stress on components,
  • stable temperatures and improved humidity control.

The system also supports heat recovery, increasing overall energy efficiency and improving return on investment.

Low noise as a competitive advantage

Steady low-speed operation, variable fan control, an isolated compressor compartment, and night mode functionality result in exceptionally low sound levels. Measured noise values below 30 dBA make Silensys® suitable for noise-sensitive locations without compromising performance.

 

Engineering focused on durability

Silensys® features start-up pre-ventilation, a suction accumulator, and an oil separator. This robust design ensures reliable oil return, reduces overheating risks, and extends compressor lifetime, even during long periods of part-load operation.

Flexibility for modern refrigerants

The unit supports R448A, R449A, R455A, and R454C refrigerants and covers a wide range of cooling capacities for low and medium back-pressure applications. Availability in L and XL sizes allows precise matching to specific project requirements.

Silensys® Inverter Scroll is not just a technical product—it is a strategic investment for businesses seeking lower operating costs, enhanced system reliability, and compliance with increasingly strict noise and energy-efficiency requirements.
