Outdoor Refrigeration Units: Noise, Correct Placement and Relations with Neighbours

Author: Echipa Modaco

Why the placement of an outdoor refrigeration unit matters

Any food shop, restaurant or HoReCa establishment that uses professional refrigeration equipment will sooner or later face a practical question: where do we install the outdoor unit, and how do we make sure we don't disturb the neighbours? The question is far from trivial. A refrigeration unit placed incorrectly can generate complaints, sanctions from local authorities and even disputes with neighbouring property owners. At the same time, incorrect placement also affects the efficiency of the equipment.

This guide is aimed at business owners and managers — neighbourhood shops, supermarkets, restaurants, cafés, guesthouses — who are installing or planning to install outdoor refrigeration units and want to do so responsibly.

The main noise sources of an outdoor unit

An outdoor refrigeration unit (condensing unit or monobloc unit) contains a compressor, a fan and, in some cases, additional pumps or fans. Noise comes primarily from:

  • The compressor — the component with the highest noise level, especially at start-up and under full load;
  • The condenser fans — they produce continuous noise, especially during periods of high temperatures when they run intensively;
  • Vibrations transmitted through the structure — if the unit is fixed directly to a wall or a concrete slab without anti-vibration elements, the sound propagates into the building interior and into adjacent buildings.

The noise level varies depending on the power and type of unit. The TEFCOLD CRU3050N monobloc refrigeration unit, for example, is a compact piece of equipment designed for outdoor installation, with clear noise specifications stated in the product data sheet — always check these values before choosing a unit.

Regulations and noise limits in Romania

Romanian legislation, through STAS 10009 and local urban planning regulations, sets noise limits for residential and mixed-use areas. In general, the permitted values are stricter at night than during the day. Local authorities (the town hall, the Environmental Guard) can inspect, following a neighbour's complaint, whether the equipment exceeds the permitted level and may impose fines or even require the equipment to be shut down.

Before any installation, consult the urban development plan for the area and, where applicable, request approval from the town hall or the Environmental Guard. The technical documentation of the unit, which includes noise data, will be required during this process.

How to correctly position an outdoor refrigeration unit

A few practical rules every business should keep in mind:

  • Distance from neighbours' windows and doors — the further the unit is from the windows of adjacent dwellings, the lower the perceived noise level. Direct hot air exhaust towards open spaces, not towards windows.
  • Anti-vibration mounts — install the unit on anti-vibration rubber mounts or pads. This measure significantly reduces noise transmitted through the building structure.
  • Avoid mounting on walls shared with dwellings — vibrations are transmitted directly into the load-bearing structure and from there into neighbouring flats or houses.
  • Check maintenance access — the unit must be accessible to an authorised technician for periodic servicing. A cramped space complicates the work and increases service costs.
  • Observe minimum clearances from obstacles — the manufacturer specifies minimum installation clearances in the technical documentation to ensure correct airflow. Failure to observe them reduces efficiency and increases the compressor's operating temperature.

Always consult the instructions for use, cleaning, maintenance and placement of your equipment. These contain the manufacturer's specific requirements, including installation clearances and ventilation conditions.

Relations with neighbours: communicate before problems arise

Beyond legal obligations, a good relationship with neighbours is built through proactive communication. Inform them before installation about the type of equipment and its operating schedule. If your business involves night-time operation, consider sound-absorbing barriers or special enclosures for noise reduction — certified commercial solutions compatible with standard units are available.

Another important aspect: regular maintenance of the unit reduces noise in the long run. Dirty fans or poorly maintained compressors work harder and more noisily than clean, periodically inspected equipment.

What MODACO offers businesses looking for professional refrigeration equipment

MODACO provides businesses with a complete range of commercial refrigeration equipment, including outdoor units and monobloc systems. If you are purchasing equipment for your own operations, you can request a bulk wholesale quote. Companies registered in Romania that wish to resell the equipment can apply for the B2B Partner Programme, which offers personalised commercial terms, a product feed for online shops and the option of direct delivery to the end customer.

In-stock products are delivered quickly (24–48 hours), while items sourced to order from imports are delivered within 15–25 working days. Payment can be made by bank transfer, online card payment or cash on collection from the warehouse in Găești (only for buyers with a CUI and within the legal cash limit).
