Silent Pack condensing units for low-noise refrigeration installations

Silent Pack Condensing Units are compact, acoustically efficient refrigeration units designed for installations where noise is a critical factor: cold rooms in urban areas, ground-floor shops, workshops next to residential areas or any installation subject to local noise restrictions. The Silent Pack design integrates the compressor, condenser and circuit accessories in a soundproofed casing, significantly reducing noise emissions compared with equivalent conventional units.

Technical specifications

  • Soundproofed casing with high-efficiency acoustic absorbing material
  • Scroll or hermetic reciprocating compressor
  • Condenser with low-noise, high-efficiency fan motors
  • Compatible with R-404A, R-448A, R-449A, HFO blends and A2L refrigerants depending on model
  • Built-in electrical panel with compressor protection and pressure switches
  • Available versions: low temperature (LT) and medium temperature (MT)
  • Wide range of capacities for cold rooms of any size

Advantages

✔ Reduced noise level: meets the most demanding local noise ordinances
✔ Compact plug & play installation with no plant room
✔ Outdoor installation without disturbing neighbours or staff
✔ High energy efficiency to reduce the cold room’s operating cost
✔ Built-in electrical panel for quick installation
✔ Wide range for chilled and frozen applications of any capacity

Applications

Cold rooms in urban retail premises (butcher shops, fishmongers, supermarkets); catering kitchens in residential areas; cold rooms in mixed-use buildings; industrial installations on estates with noise emission limits; any installation where noise standards are a design constraint.

Standards and compliance

Noise emissions from refrigeration equipment are subject to local noise ordinances, in accordance with Spanish Royal Decree 1367/2007 on acoustic zoning and noise emissions. The refrigerants used are subject to the F-Gas Regulation (EU) 517/2014. A2L models meet the latest GWP reduction guidelines of the European refrigeration industry.

FAQs

How much noise does a Silent Pack condensing unit make?

Depending on model and capacity, Silent Pack units emit between 45 and 58 dB(A) at 1 metre, compared with 60-70 dB(A) for equivalent conventional units. The lowest level is roughly equivalent to a normal conversation in a quiet setting.

Can I install a Silent Pack indoors?

Silent Pack units are designed for outdoor use. However, their low noise level allows them to be installed in inner courtyards or on roofs close to neighbours. Indoor installation requires ventilation ducts to remove heat from the condenser. Check the specific conditions of the selected model.

Which version do I need for a freezer room at -20 °C?

For freezer rooms you need the low temperature (LT) version, optimised for evaporating temperatures of -35 °C to -45 °C, which allows the cold room to be kept between -18 °C and -25 °C with the necessary margin. Make sure you specify the design temperature and ambient conditions when selecting the model.
