What are the primary benefits of ammonia refrigeration?

Ammonia is highly efficient, has excellent thermodynamic properties, and is environmentally friendly with zero global warming potential (GWP) and ozone depletion potential (ODP). It is also generally more cost-effective as a refrigerant.

What safety considerations are important for ammonia systems?

Ammonia is toxic and flammable in certain concentrations, requiring robust safety protocols, leak detection systems, proper ventilation, and trained personnel for operation and maintenance. Compliance with relevant safety regulations is essential.

Can this unit be integrated into an existing refrigeration system?

Integration is often possible but depends on the existing system's design, capacity requirements, and control infrastructure. A detailed assessment by a qualified refrigeration engineer would be necessary.

What is the typical lifespan of an industrial ammonia refrigeration pack?

With regular servicing and maintenance, industrial ammonia refrigeration packs can have a lifespan of 20 to 30 years, or even longer for well-maintained units.

What is the significance of having a spare motor?

A spare motor provides critical redundancy, allowing for quicker repairs and minimising downtime in the event of a motor failure on an operational compressor.

Is the Baltimore Condenser included with the refrigeration pack?

The description indicates the condenser is 'available with' the pack. Buyers should confirm with the seller whether it is included in the stated price or offered separately.

Informazioni tipiche per questa categoria di macchinari. Verifichi sempre i dettagli con il venditore.

Large-scale cold storage facilities for food processing and distribution.
Industrial refrigeration for chemical and pharmaceutical production.
Blast freezing and chilling operations in the food industry.
Breweries and distilleries requiring precise temperature control.

Typical capacity: Industrial ammonia refrigeration packs commonly range from 500 kW to several megawatts, with this specific unit offering 884 kW total capacity.
Compressor type: This unit features Howden screw compressors, known for their efficiency and reliability in continuous operation.
Refrigerant: Ammonia (R717) is the specified refrigerant, valued for its high efficiency and zero ozone depletion potential, though it requires specific safety protocols.
Configuration: Units of this type often feature multiple compressors (e.g., two high-side, one low-side) to provide redundancy and optimise performance across varying loads.
Power supply: Industrial refrigeration packs typically require a three-phase electrical supply, commonly 400V or 415V, 50Hz, with significant current draw.
Ancillary equipment: Such packs are usually paired with evaporative condensers (e.g., Baltimore VXC series), receivers, and control systems.
Maintenance: Regular servicing and maintenance are crucial for ammonia refrigeration systems to ensure safety, efficiency, and longevity.

Ammonia is highly efficient, has excellent thermodynamic properties, and is environmentally friendly with zero global warming potential (GWP) and ozone depletion potential (ODP). It is also generally more cost-effective as a refrigerant.

Cold rooms and refrigeration units are considered essential assets in food processing operations. Buyers typically prioritise reliability, energy efficiency, and ease of maintenance when selecting used models. Industry sentiment favours equipment from reputable manufacturers known for durability. Key considerations include checking refrigerant systems, insulation condition, and temperature consistency. Well-maintained units often deliver strong performance at reduced cost compared to new alternatives, making them attractive for budget-conscious operations seeking dependable temperature control.
